Introduction

Secondment is a common arrangement in the Philippine public sector. A government employee may be temporarily assigned or detailed to another government office, government-owned or controlled corporation, international organization, foreign-assisted project, or even, in limited cases, an entity outside the employee’s original agency. During this period, questions often arise about salary, leave credits, employer obligations, and retirement benefits.

One important issue is whether a government employee on secondment may continue paying contributions to the Government Service Insurance System, or GSIS, on a voluntary basis.

The short answer is: generally, a government employee on secondment may continue GSIS coverage if the secondment does not sever government employment and if the employee remains within compulsory GSIS coverage. However, the arrangement must be carefully examined because GSIS contributions are not purely a matter of private choice. GSIS coverage depends on the employee’s legal employment status, the paying employer, the nature of the secondment, and the rules on compulsory and optional insurance coverage.

Voluntary continuation may be possible in some cases, but it is not automatic in all secondment situations.

I. GSIS Coverage in the Philippine Public Sector

The GSIS is the social insurance institution for government employees. Its governing law is Republic Act No. 8291, also known as the GSIS Act of 1997.

As a general rule, GSIS coverage applies to:

Government employees receiving compensation;
Employees of national government agencies;
Employees of local government units;
Employees of government-owned or controlled corporations with original charters;
Members of the judiciary, constitutional commissions, and other government offices covered by law.

GSIS membership is generally compulsory, not optional, for covered government employees. This means that a covered government employee and the government employer must pay the required employee and employer shares.

GSIS contributions are usually composed of:

Personal share — deducted from the employee’s salary; and
Government share — paid by the government employer.

The usual legal structure assumes an active government employment relationship. The contribution obligation is tied to compensation and service in government.

II. What Is Secondment?

Secondment is the temporary movement or assignment of an employee from the mother agency to another office or institution, usually for a specific purpose and duration.

It differs from resignation, transfer, detail, reassignment, or leave without pay.

In secondment, the employee normally retains some connection with the original government agency. Depending on the terms, the employee may:

Remain an employee of the mother agency;
Receive salary from the receiving agency or institution;
Be carried on leave or special assignment status in the mother agency;
Return to the mother agency after the secondment period;
Continue to be governed by civil service, public accountability, and benefit rules.

The key legal question is not simply whether the employee is physically serving elsewhere. The key question is whether the employee’s government employment remains legally active for purposes of GSIS coverage.

III. The Central Issue: Can GSIS Contributions Continue During Secondment?

A government employee on secondment may generally continue GSIS contributions when the following conditions are present:

The employee remains in government service;
The secondment is officially authorized;
The employment relationship with the government is not severed;
The employee remains within the class of employees covered by GSIS;
There is a mechanism for remitting both employee and employer shares, where required;
GSIS recognizes the service and contribution arrangement.

The issue becomes more complicated if the employee is seconded to an entity that is not a GSIS-covered employer, such as an international organization, foreign-funded office, private entity, or non-GSIS institution.

In those cases, the employee may need to arrange continued remittance through the mother agency or directly with GSIS, depending on the applicable GSIS rules and the specific terms of secondment.

IV. Voluntary Contributions: What Does “Voluntary” Mean?

The phrase “voluntary GSIS contributions” can mean different things.

It may refer to:

Voluntary continuation of coverage while temporarily outside regular payroll;
Payment of the employee’s personal share when salary is not paid by the mother agency;
Payment of both employee and government shares when no covered government employer is remitting the employer share;
Settlement of arrears or gaps to preserve creditable service;
Optional insurance arrangements recognized by GSIS rules.

It is important to understand that GSIS is not like a purely private savings account where a person may simply contribute any amount at any time. Contributions are governed by law, membership status, compensation, and employer reporting.

A seconded employee cannot simply assume that paying money to GSIS will automatically result in creditable service. The payment must correspond to a recognized coverage status and must be accepted and posted by GSIS under its rules.

V. When Continued GSIS Contributions Are Usually Allowed

A. Secondment to Another Government Agency Covered by GSIS

If the employee is seconded from one GSIS-covered government agency to another GSIS-covered government agency, continued contributions are generally less problematic.

For example, a national government employee may be seconded to another national agency or a government-owned corporation with an original charter. If the receiving agency pays the salary and is a GSIS-covered employer, the employee’s GSIS deductions and employer counterpart may continue through that receiving agency.

The parties should clarify:

Which agency pays the salary;
Which agency remits GSIS contributions;
Whether the employee remains on the plantilla of the mother agency;
Whether the receiving agency assumes employer obligations;
Whether the service will be reported as creditable government service.

In this situation, the contributions may not truly be “voluntary” in the private sense. They continue because the employee remains under compulsory GSIS coverage.

B. Secondment While Salary Remains Paid by the Mother Agency

If the employee remains on the payroll of the original agency, GSIS contributions may continue in the normal manner. The personal share is deducted from salary, and the government share is remitted by the agency.

This is the cleanest arrangement from a GSIS perspective because the employee remains in the usual payroll-contribution system.

C. Secondment to a Foreign-Assisted or Special Project Under Government Supervision

Some government employees are seconded to foreign-assisted projects or special project offices. If the project is implemented through or under a Philippine government agency, the employee may remain covered by GSIS, especially if the mother agency or implementing agency continues to recognize the employment relationship.

The important point is whether the employee’s compensation and service remain connected to covered government employment.

D. Secondment to an International Organization

Secondment to an international organization is more complex.

The employee may remain a Philippine government employee, but the host organization may not be a GSIS-covered employer. It may not be legally obligated or administratively able to remit GSIS employer shares.

In such cases, continued GSIS coverage may depend on:

The secondment agreement;
Approval by the mother agency;
Whether the employee is considered on leave, special detail, or active secondment;
Whether the government employer share will be paid by the mother agency, receiving organization, or employee;
GSIS approval of the remittance arrangement.

Some arrangements require the seconded employee to shoulder both the employee and employer shares to avoid interruption of service credit. This should be expressly confirmed with GSIS and the mother agency.

VI. When Continued Contributions May Not Be Allowed or May Be Questioned

A. If the Employee Has Resigned

A resigned government employee generally ceases to be an active compulsory GSIS member. If the so-called secondment is actually a resignation followed by employment elsewhere, the person may no longer be entitled to continue regular GSIS contributions as an active government employee.

The label used by the parties is not controlling. What matters is the legal status of the employment.

B. If the Employee Transfers to a Non-GSIS Employer

If the employee moves to a private employer, a foreign employer, or an entity not covered by GSIS, and the government employment relationship is terminated, GSIS compulsory coverage usually ends.

The employee may still have vested rights or benefits based on prior government service, but that is different from continuing active GSIS contributions.

C. If the Employee Is on Leave Without Pay Without an Approved Contribution Arrangement

A government employee on leave without pay may experience gaps in contribution payments. Whether the period is creditable for GSIS purposes depends on applicable GSIS and civil service rules, as well as whether contributions are paid and accepted.

If the secondment is treated as leave without pay from the mother agency, the employee should not assume automatic crediting of service. The employee must verify whether contributions may be continued and what amount must be paid.

D. If No Employer Share Is Remitted

GSIS contributions involve both the personal share and the government share. If only the personal share is paid without the required government share, the contribution record may be incomplete.

In some cases, the employee may have to pay both shares if allowed by GSIS rules. In other cases, GSIS may require the government agency to report and remit the employer counterpart.

E. If GSIS Does Not Recognize the Employment Status

Even if an agency permits secondment, GSIS may still need proper documentation before recognizing the period for contribution and service-credit purposes.

A contribution payment made without proper reporting may create posting problems, arrears, or later disputes.

VII. The Role of the Mother Agency

The mother agency is central to the issue.

A seconded employee should determine whether the mother agency will:

Keep the employee on its plantilla;
Continue reporting the employee to GSIS;
Continue paying the government share;
Deduct the employee share from salary, if any;
Treat the secondment period as creditable service;
Issue certifications required by GSIS;
Allow the employee to reimburse or directly pay contributions if salary is paid elsewhere.

If the mother agency remains the official employer, it may have a continuing role in GSIS reporting. If the receiving agency assumes payment obligations, the secondment agreement should clearly say so.

VIII. The Role of the Receiving Agency or Host Institution

The receiving entity may or may not be a GSIS-covered employer.

If it is a Philippine government agency covered by GSIS, it may be able to deduct and remit contributions.

If it is not GSIS-covered, it may have no ordinary legal mechanism to remit GSIS employer contributions. In that situation, the secondment agreement should address whether the host will:

Reimburse the mother agency for employer contributions;
Pay an equivalent amount to the employee;
Allow the employee to shoulder contributions;
Coordinate directly with GSIS;
Recognize Philippine social insurance obligations in the assignment package.

This is especially important for secondments to international organizations, development agencies, foreign-funded offices, and regional bodies.

IX. Effect on Creditable Service

The main reason employees want to continue GSIS contributions during secondment is to avoid a break in creditable service.

Creditable service matters for:

Retirement eligibility;
Separation benefits;
Life insurance benefits;
Disability benefits;
Survivorship benefits;
Loan privileges;
Computation of length of government service.

A secondment period may be creditable if it is legally recognized as government service and the required contributions are paid. But if the employee’s status is unclear or contributions are not properly remitted, the period may later be disputed.

A seconded employee should obtain written confirmation regarding whether the secondment period will be treated as creditable service for GSIS purposes.

X. Effect on Retirement Benefits

Failure to continue GSIS contributions may affect retirement benefits, especially if the gap affects:

Minimum service requirements;
Average monthly compensation calculations;
Total length of service;
Qualification under a particular retirement mode;
Loan balances or arrears;
Insurance coverage.

However, a contribution gap does not necessarily erase prior service. The employee’s previous creditable service remains relevant. The problem is whether the secondment period itself will be counted and whether benefits may be reduced, delayed, or complicated by unpaid premiums.

XI. Effect on GSIS Loans

GSIS loan eligibility and standing may also be affected by secondment.

If contributions stop or the employee is no longer reported as active, the employee may face issues with:

Policy loans;
Salary loans;
Emergency loans;
Consolidated loans;
Loan amortization deductions;
Penalties and interest;
Renewal eligibility.

A seconded employee with outstanding GSIS loans should clarify how amortizations will be paid during secondment. If payroll deduction stops, the employee may need an alternative payment arrangement.

Unpaid loan amortizations can accumulate and affect future benefits.

XII. Effect on Life Insurance and Other Coverage

GSIS membership includes social insurance components beyond retirement. These may include life insurance, disability, survivorship, and other benefits under applicable rules.

If contributions lapse or coverage status changes, the employee should verify whether insurance protection continues during secondment. This is particularly important for employees assigned abroad or to higher-risk environments.

XIII. Secondment Versus Detail, Reassignment, Transfer, and Leave

The legal treatment of GSIS contributions depends heavily on the nature of the personnel action.

A. Detail

A detail usually involves temporary movement to another office without a change in position or agency. The employee often remains on the payroll of the mother agency. GSIS contributions usually continue normally.

B. Reassignment

Reassignment is movement within the same department or agency structure. Since government employment continues, GSIS coverage usually continues.

C. Transfer

A transfer may involve movement from one agency to another. If both are GSIS-covered and there is no break in service, contributions may continue, but records must be properly transferred or updated.

D. Leave Without Pay

Leave without pay may interrupt salary-based deductions. Contributions may stop unless rules allow continuation or settlement.

E. Secondment

Secondment is distinct because the employee may serve outside the mother agency while retaining employment ties. This creates the need for a clear contribution arrangement.

XIV. Who Must Pay the Contributions?

The usual GSIS contribution structure requires both employee and employer shares.

During secondment, possible payment models include:

Mother agency pays salary and remits both shares. This is administratively straightforward.
Receiving GSIS-covered agency pays salary and remits both shares. This may apply when the host is another government agency.
Mother agency remits, receiving entity reimburses. This may be used for special projects or inter-agency secondments.
Employee pays personal share, agency pays government share. This may occur when salary is paid outside ordinary payroll but the agency continues employer responsibility.
Employee pays both personal and government shares, if allowed. This may be considered where the host is not a GSIS-covered employer and the agency will not shoulder the employer share.

The last model should not be assumed. It must be verified with GSIS because employer-share obligations are created by law and cannot always be privately rearranged without approval.

XV. Documentation Needed

A seconded employee should secure and keep copies of the following:

Approved secondment order;
Memorandum of agreement or secondment agreement;
Approval from the mother agency;
Acceptance by the receiving agency or host institution;
Payroll arrangement;
Statement on who pays salary;
Statement on who remits GSIS employee share;
Statement on who remits GSIS employer share;
Certification of continued government employment;
GSIS confirmation of contribution arrangement;
Receipts or proof of payment;
Updated GSIS service record;
Loan payment confirmations, if applicable.

Written documentation is critical because GSIS issues often arise years later, usually when the employee applies for retirement or benefits.

XVI. Practical Steps for the Employee

A government employee on secondment should do the following before leaving the mother agency:

Ask the human resource office whether the secondment will be treated as creditable government service.
Ask the accounting or payroll office who will remit GSIS contributions.
Ask whether the government share will continue to be paid.
Confirm whether the receiving entity will reimburse the mother agency.
Request written confirmation from GSIS if the arrangement is unusual.
Check outstanding GSIS loans.
Arrange loan amortization payments if payroll deduction will stop.
Monitor GSIS records during the secondment.
Keep all official receipts and certifications.
Resolve contribution gaps immediately, not at retirement.

XVII. Practical Steps for the Mother Agency

The mother agency should not approve secondment without addressing GSIS implications.

It should specify:

Whether the employee remains in active government service;
Whether the period is creditable service;
Whether salary is paid by the mother agency or host;
Who remits employee and employer shares;
Who is responsible for arrears;
How GSIS loans will be handled;
Whether the employee must execute an undertaking;
Whether the arrangement has been cleared with GSIS.

A vague secondment order can create serious problems later.

XVIII. Practical Steps for the Receiving Entity

The receiving agency or host should clarify:

Whether it is a GSIS-covered employer;
Whether it can deduct employee contributions;
Whether it will pay or reimburse employer contributions;
Whether its compensation package includes social insurance support;
Whether it will coordinate with the mother agency;
Whether it will issue certifications needed by GSIS.

If the receiving entity is an international organization, the arrangement should be stated in writing because the organization may not be subject to Philippine payroll and social insurance systems.

XIX. Common Problems During Secondment

A. Contributions Stop Without the Employee Knowing

Some employees discover only later that GSIS deductions stopped when they moved to the host institution.

This can happen when the mother agency removes the employee from active payroll while the host does not remit GSIS contributions.

B. Employee Pays Only the Personal Share

The employee may pay what would normally be deducted from salary but fail to account for the government share. This may result in incomplete coverage.

C. Salary Basis Is Unclear

GSIS contributions are tied to compensation. If the employee receives a different salary during secondment, questions may arise about the correct contribution base.

D. Host Institution Is Not GSIS-Covered

An international or private host may not know how to handle GSIS obligations. The employee may be left to coordinate alone.

E. Records Are Not Updated

Even when payments are made, they may not be properly posted if the agency fails to submit required reports.

F. Issues Are Discovered Only at Retirement

Contribution gaps often surface when the employee applies for retirement benefits. By then, records may be difficult to reconstruct.

XX. Can the Employee Pay Directly to GSIS?

Direct payment may be possible in certain cases, but it should be cleared with GSIS.

The employee should not rely merely on informal advice. The employee should ask GSIS whether direct payment will be accepted and credited for the specific secondment period.

Important questions include:

Am I still considered an active GSIS member during secondment?
May I pay contributions directly?
Must I pay both employee and employer shares?
What salary base will be used?
Will the period be counted as creditable service?
What documents are required from my agency?
How will my loan amortizations be handled?
How can I verify posting of payments?

The safest approach is to obtain written GSIS confirmation before making payments.

XXI. Can the Employee Shoulder the Government Share?

In some secondment arrangements, particularly where the employee is assigned to a non-GSIS host, the employee may be asked to shoulder both personal and government shares.

This may be allowed only if consistent with GSIS rules and the approved arrangement. The government share is normally an employer obligation, so shifting it to the employee should not be treated casually.

If the employee agrees to shoulder both shares, the agreement should specify:

The legal basis;
The amount;
The payment schedule;
The salary base;
The effect on creditable service;
The agency’s reporting obligations;
GSIS acceptance of the arrangement.

Without GSIS recognition, the employee may pay amounts that are not properly credited.

XXII. Does Secondment Interrupt Government Service?

Not necessarily.

Secondment is generally temporary and may preserve the employee’s link with the government. However, whether the period counts as uninterrupted government service depends on the terms of the appointment, the secondment order, civil service rules, agency approval, and GSIS recognition.

A seconded employee should distinguish between:

Employment status — whether the employee remains a government employee;
Payroll status — whether the employee is paid by the mother agency or host;
Contribution status — whether GSIS premiums are remitted;
Service-credit status — whether the period counts for retirement and benefits.

These are related but not identical.

XXIII. Effect of Compensation Changes During Secondment

The employee may receive a different salary, allowance, honorarium, stipend, or foreign-currency compensation during secondment.

This creates questions about the proper GSIS contribution base.

Possible approaches include:

Contributions based on the employee’s regular government salary;
Contributions based on compensation paid by the receiving agency;
Contributions based on a special approved salary rate;
Contributions based only on compensation recognized by GSIS.

Not all payments received during secondment are necessarily treated as GSIS-covered compensation. Allowances, foreign-service support, per diems, or project-based payments may be treated differently depending on rules and the nature of the payment.

This should be clarified before secondment begins.

XXIV. Secondment Abroad

A secondment abroad adds additional concerns.

The employee should clarify:

Whether the Philippine government employment relationship continues;
Whether the host abroad will pay any social security contribution;
Whether Philippine GSIS contributions will continue;
Whether the employee will also be covered by foreign social insurance;
Whether Philippine taxes and payroll deductions continue;
Whether benefits are affected by foreign-currency compensation;
Whether the secondment period is included in Philippine government service records.

Foreign assignment does not automatically terminate GSIS coverage. But if the assignment removes the employee from Philippine government payroll and reporting, the employee must ensure a proper continuation mechanism.

XXV. Secondment to a GOCC

A government-owned or controlled corporation may or may not be covered by GSIS depending on its charter and legal status.

GOCCs with original charters are generally within the government service framework and commonly fall under GSIS. However, some government-linked corporations organized under the Corporation Code may have different social insurance treatment.

Therefore, when seconded to a GOCC, the employee should confirm whether the receiving GOCC is a GSIS-covered employer. If it is, contributions may continue through that GOCC. If not, special arrangements may be needed.

XXVI. Secondment to Local Government Units

Secondment to a local government unit generally remains within the public sector. LGU employees are typically covered by GSIS. If a national government employee is seconded to an LGU, the parties should clarify which entity pays salary and remits contributions.

The service may remain creditable if properly documented and reported.

XXVII. Secondment to the Private Sector

Secondment to a private-sector entity is less common and more legally sensitive.

If a government employee is temporarily assigned to a private entity while retaining government employment, questions may arise regarding:

Civil service rules;
Conflict of interest;
Salary source;
Accountability;
GSIS coverage;
Employer contribution obligations;
Whether the arrangement is legally permissible.

A private entity is ordinarily not a GSIS-covered employer. If the employee remains a government employee, the mother agency and GSIS must clarify how contributions will continue. If government employment is terminated, active GSIS coverage generally ceases.

XXVIII. Legal Character of GSIS Benefits During Secondment

GSIS benefits are statutory. They are not created merely by agreement between the employee and the host institution.

A secondment agreement cannot, by itself, force GSIS to credit service or accept contributions contrary to law or GSIS rules. The agreement must be consistent with the GSIS Act, civil service rules, and GSIS implementing policies.

Therefore, even a well-written secondment contract should be supported by agency reporting and GSIS recognition.

XXIX. Importance of No Break in Service

Many public officers aim to maintain continuous government service because certain benefits depend on length of service. A break may affect retirement timing, benefit computations, and eligibility.

Secondment can preserve continuity if properly handled. But a contribution gap may cast doubt on whether the entire period is creditable.

The safest practice is to ensure that the secondment order expressly states that the employee remains in government service and that GSIS contributions will continue according to an approved arrangement.

XXX. Arrears and Retroactive Payments

If contributions were not paid during secondment, the employee may later seek to settle arrears. Whether GSIS will allow retroactive payment depends on the circumstances and applicable rules.

Relevant considerations may include:

Whether the employee was still legally in government service;
Whether the agency should have remitted contributions;
Whether the omission was administrative error;
Whether employer share can still be paid;
Whether the period can still be validated as creditable service;
Whether penalties or interest apply;
Whether the claim is timely and adequately documented.

Retroactive correction is usually harder than proper prospective arrangement. Employees should not wait until retirement to fix contribution gaps.

XXXI. Agency Liability for Non-Remittance

If a covered employee remains in government service and the agency fails to remit required GSIS contributions, the agency may be responsible for remittance deficiencies.

Government employers have statutory obligations to deduct and remit required premiums. Non-remittance may expose the agency to administrative and financial consequences.

However, where the secondment arrangement is ambiguous or salary is paid outside regular payroll, responsibility may be disputed. This is why secondment documents should assign responsibility clearly.

XXXII. Employee Liability and Responsibility

The employee also has practical responsibility to monitor records.

Even if the agency is legally responsible for remittance, the employee may suffer the immediate consequences of contribution gaps. The employee should regularly check GSIS records and obtain proof that contributions are posted.

A seconded employee should not rely solely on verbal assurances from HR or payroll personnel.

XXXIII. Recommended Clauses in a Secondment Agreement

A secondment agreement should include a GSIS clause. A useful clause may address:

The employee’s continued status as a government employee;
The duration of secondment;
The salary source;
The contribution base;
Responsibility for employee share;
Responsibility for government share;
Method and schedule of remittance;
Handling of GSIS loans;
Treatment of the period as creditable service;
Duty to provide certifications;
Responsibility for penalties, interest, or arrears;
Requirement of GSIS clearance or confirmation.

A sample formulation:

During the period of secondment, the employee shall remain in government service for purposes of applicable civil service and GSIS rules, subject to confirmation by GSIS. The parties shall ensure the continued remittance of required GSIS contributions, including the personal and government shares, in accordance with law and GSIS regulations. The responsible remitting entity shall be identified in the payroll and administrative arrangements attached to this Agreement. Any change in compensation source or payroll status shall be immediately reported to the mother agency and GSIS.

This clause should be adapted to the specific arrangement.

XXXIV. Common Scenarios and Likely Treatment

Scenario 1: Employee seconded to another national government agency

GSIS contributions generally continue because both agencies are within the government system. The main issue is which agency remits.

Scenario 2: Employee seconded to an LGU

Coverage likely continues if properly reported. The parties must clarify payroll and remittance responsibility.

Scenario 3: Employee seconded to a GOCC with original charter

Coverage likely continues if the GOCC is GSIS-covered. Payroll transfer and reporting must be handled.

Scenario 4: Employee seconded to a GOCC without original charter or non-GSIS entity

Coverage may require special arrangement. The employee should confirm whether the host is GSIS-covered.

Scenario 5: Employee seconded to an international organization

Coverage may continue only if government employment remains active and GSIS accepts the remittance arrangement. The employee may need to coordinate direct payment or payment through the mother agency.

Scenario 6: Employee resigns from government and joins another institution

Active GSIS contributions generally stop. Prior GSIS rights remain subject to law, but regular compulsory coverage no longer continues.

Scenario 7: Employee is on leave without pay while serving elsewhere

Coverage and crediting depend on rules, agency approval, and payment of required contributions. This is a high-risk scenario for contribution gaps.

XXXV. Key Legal Principles

Several principles guide the issue:

GSIS coverage is statutory. It exists because the law says so, not merely because the employee wants to contribute.
Compulsory coverage follows covered government employment. If government employment continues, GSIS coverage will usually continue.
Secondment does not automatically end government employment. But the documents must show continued status.
Contributions require proper remittance and reporting. Payment alone is not enough if not properly posted and recognized.
The employer share matters. Paying only the personal share may not fully preserve coverage.
The mother agency remains important. It often provides the legal link between the employee and GSIS.
GSIS confirmation is essential in unusual cases. Especially where the host is not a GSIS-covered employer.

XXXVI. Risks of Not Clarifying GSIS Contributions

Failure to clarify the issue may result in:

Breaks in contribution records;
Reduced or delayed retirement benefits;
Disputes over creditable service;
Loan arrears;
Loss or reduction of insurance protection;
Difficulty proving service years;
Administrative disputes between agencies;
Personal financial liability for unpaid shares;
Problems in retirement processing;
Need for retroactive correction.

These risks are avoidable through clear documentation and early coordination.

XXXVII. Best Practices

For the employee:

Secure written approval of secondment.
Confirm whether government employment continues.
Ask who pays the GSIS personal share.
Ask who pays the GSIS government share.
Confirm the salary base for contributions.
Check GSIS records regularly.
Keep payment receipts.
Monitor loan amortizations.
Obtain written GSIS guidance for unusual arrangements.
Resolve gaps immediately.

For the agency:

Include GSIS terms in the secondment order.
Coordinate with accounting and HR before deployment.
Avoid vague payroll arrangements.
Ensure proper remittance reports.
Inform the employee of obligations.
Coordinate with GSIS if the host is not covered.
Maintain updated service records.

For the receiving entity:

State whether it will pay salary.
State whether it will reimburse contributions.
Coordinate with the mother agency.
Provide employment and compensation certifications.
Avoid assuming GSIS will automatically recognize the arrangement.

XXXVIII. Legal Conclusion

A government employee on secondment in the Philippines may continue GSIS contributions when the secondment preserves the employee’s government employment status and the required contributions are properly remitted and recognized by GSIS.

Where the employee remains on the payroll of the mother agency or is seconded to another GSIS-covered government agency, continued contributions are usually straightforward. Where the employee is seconded to a non-GSIS entity, international organization, foreign-assisted project, or private host, continued contributions may still be possible, but only through a valid arrangement involving the employee, the mother agency, the host institution, and GSIS.

The critical questions are:

Does the employee remain a government employee?
Is the secondment officially authorized?
Who pays the salary?
Who remits the employee share?
Who remits the government share?
What compensation base is used?
Will GSIS credit the period as government service?
Are loan amortizations and insurance coverage preserved?

The safest legal position is that a seconded government employee should not rely on informal “voluntary contribution” assumptions. The employee should secure written confirmation from the agency and GSIS that the secondment period is covered, that contributions may continue, and that the payments will be credited for benefit and retirement purposes.

In sum: yes, continuation of GSIS contributions during secondment is possible, but it depends on the employee’s continuing government status, the nature of the host entity, the payment of both required shares, and GSIS recognition of the arrangement.
