The “semester of contingency” is the part of the SSS maternity benefit computation that causes the most confusion. It does not mean the six months immediately before childbirth, and it is not based simply on the expected delivery date. SSS first excludes a six-month semester determined by the actual quarter of childbirth, miscarriage, or emergency termination of pregnancy. It then looks at the 12 months immediately before that excluded semester to determine whether the member has enough qualifying contributions and how much benefit she may receive.
What Is the SSS Semester of Contingency?
For SSS maternity purposes, the contingency is the event that gives rise to the benefit:
- Live childbirth, whether normal or caesarean;
- Miscarriage;
- Stillbirth or fetal death; or
- Emergency termination of pregnancy, including qualifying cases such as ectopic pregnancy.
A semester of contingency consists of two consecutive calendar quarters ending in the quarter when the contingency occurs. One quarter is a three-month period ending in March, June, September, or December. (Social Security System)
The four calendar quarters are:
| Quarter | Covered months |
|---|---|
| First quarter | January, February, March |
| Second quarter | April, May, June |
| Third quarter | July, August, September |
| Fourth quarter | October, November, December |
The semester therefore includes:
- The quarter in which the childbirth, miscarriage, or emergency termination occurs; and
- The immediately preceding quarter.
The entire six-month semester is excluded when SSS determines the qualifying contribution period and computes the benefit.
Legal Basis for the Maternity Benefit Coverage Rule
Section 5 of Republic Act No. 11210, or the 105-Day Expanded Maternity Leave Law, requires an SSS member to have at least three monthly contributions within the 12-month period immediately preceding the semester of childbirth, miscarriage, or emergency termination of pregnancy. The law applies regardless of whether the delivery is normal or caesarean. (Supreme Court E-Library)
RA 11210 took effect in 2019 and expanded maternity leave to:
- 105 days for live childbirth;
- 120 days for a qualified solo parent, consisting of 105 days plus 15 additional days; and
- 60 days for miscarriage or emergency termination of pregnancy.
The benefit is available in every qualifying instance of pregnancy, regardless of the member’s civil status, the legitimacy of the child, or the number of previous pregnancies. (Supreme Court E-Library)
The current administrative rules are also reflected in the official SSS maternity benefit guide and the implementing rules of RA 11210.
How to Identify the Correct 12-Month Coverage Period
Use the following steps.
1. Identify the actual date of contingency
Use the actual date of childbirth, miscarriage, stillbirth, or emergency termination of pregnancy.
For a live birth, this is the child’s actual date of birth—not the estimated delivery date written in the ultrasound report or maternity notification.
Because the rule is based on the quarter in which the contingency actually occurs, an early or delayed delivery that crosses into another quarter can change the qualifying contribution period. (Social Security System)
2. Determine the calendar quarter
Place the contingency date in the correct quarter:
- January to March: first quarter;
- April to June: second quarter;
- July to September: third quarter; or
- October to December: fourth quarter.
3. Add the immediately preceding quarter
The quarter of contingency plus the preceding quarter form the six-month semester of contingency.
4. Exclude the entire semester
None of the months inside this six-month semester will be used in the maternity benefit computation.
Contributions paid within or after the semester of contingency are not considered for maternity benefit eligibility or computation. (Social Security System)
5. Count 12 months backward
Starting with the month immediately before the excluded semester, count backward for 12 months.
Those 12 months are the qualifying contribution period.
Semester of Contingency Coverage Table
This table works for any year:
| Month of childbirth, miscarriage, or ETP | Semester excluded | 12-month qualifying period |
|---|---|---|
| January, February, or March | October of the previous year to March of the current year | October two years earlier to September of the previous year |
| April, May, or June | January to June of the current year | January to December of the previous year |
| July, August, or September | April to September of the current year | April of the previous year to March of the current year |
| October, November, or December | July to December of the current year | July of the previous year to June of the current year |
Example: Childbirth in August 2026
Suppose the member gives birth on August 17, 2026.
- August falls in the third quarter: July to September 2026.
- The immediately preceding quarter is April to June 2026.
- The semester of contingency is therefore April to September 2026.
- Exclude those six months.
- Count 12 months backward from March 2026.
The qualifying contribution period is:
April 2025 to March 2026
The member must have at least three qualifying monthly contributions within that period. The contributions must also have been paid before the semester began in April 2026. (Social Security System)
Example: Childbirth in February 2026
A February 2026 delivery falls in the first quarter of 2026.
- Quarter of contingency: January to March 2026;
- Previous quarter: October to December 2025;
- Semester excluded: October 2025 to March 2026;
- Qualifying period: October 2024 to September 2025.
Contributions for October 2025 through March 2026 do not form part of the computation, even though some of those contributions may have been paid during the pregnancy.
Example: Childbirth in November 2026
A November 2026 delivery falls in the fourth quarter.
- Quarter of contingency: October to December 2026;
- Previous quarter: July to September 2026;
- Semester excluded: July to December 2026;
- Qualifying period: July 2025 to June 2026.
Why a Quarter-Boundary Delivery Can Change the Coverage Period
Consider two members—or the same member with an uncertain delivery date:
| Actual delivery date | Qualifying contribution period |
|---|---|
| March 31, 2026 | October 2024 to September 2025 |
| April 1, 2026 | January to December 2025 |
A difference of one day changes the qualifying period by three months.
For a March 31 delivery, October to December 2024 may count, while October to December 2025 will not count. For an April 1 delivery, October to December 2024 drops out, while October to December 2025 may count.
This is why a computation based only on the estimated due date is provisional. The final SSS computation follows the quarter of the actual contingency.
How Many Contributions Are Required?
A member needs at least three monthly contributions within the correct 12-month qualifying period. The three contributions do not have to be consecutive. (Social Security System)
For example, contributions for May, September, and December may satisfy the minimum requirement if all three months fall within the correct qualifying period and were paid within the applicable rules.
However, having only three contributions usually produces a lower benefit than having six qualifying contributions at the same monthly salary credit.
Eligibility and benefit amount are different questions
The three-contribution rule determines whether the member meets the minimum eligibility requirement.
The benefit amount is computed using up to the six highest monthly salary credits within the 12-month qualifying period. If the member has only three posted contributions, SSS can use only those three salary credits in the total, but the divisor remains 180 days. (Social Security System)
This means that three contributions may qualify the member, but they do not automatically produce the same benefit as six high contributions.
How to Compute the SSS Maternity Benefit
After identifying the correct 12-month period:
- List all posted monthly contributions within that period.
- Determine the monthly salary credit, or MSC, corresponding to each contribution.
- Select the six highest MSCs.
- Add those six MSCs.
- Divide the total by 180 to obtain the average daily salary credit.
- Multiply the average daily salary credit by the applicable number of maternity days.
The formula is:
Average daily salary credit = Total of the six highest MSCs ÷ 180
The benefit is then:
| Contingency | Formula |
|---|---|
| Live childbirth | Average daily salary credit × 105 |
| Qualified solo parent giving live birth | Average daily salary credit × 120 |
| Miscarriage, stillbirth, or ETP | Average daily salary credit × 60 |
The SSS maternity benefit is equivalent to 100% of the member’s average daily salary credit for the applicable compensable period. (Social Security System)
Sample computation using six contributions
Assume a member gives birth in August 2026. Her qualifying period is April 2025 to March 2026, and her six highest MSCs are:
- ₱20,000;
- ₱20,000;
- ₱18,000;
- ₱15,000;
- ₱10,000; and
- ₱8,000.
Total of the six highest MSCs:
₱20,000 + ₱20,000 + ₱18,000 + ₱15,000 + ₱10,000 + ₱8,000 = ₱91,000
Average daily salary credit:
₱91,000 ÷ 180 = ₱505.56
For a live childbirth:
₱505.56 × 105 days = approximately ₱53,083.33
For a qualified solo parent:
₱505.56 × 120 days = approximately ₱60,666.67
Sample computation with only three contributions
Suppose the member has only three qualifying contributions, each with a ₱10,000 MSC.
Total MSC:
₱10,000 × 3 = ₱30,000
Average daily salary credit:
₱30,000 ÷ 180 = ₱166.67
Benefit for live childbirth:
₱166.67 × 105 = approximately ₱17,500
The member may still qualify because she has three contributions, but the unpaid months do not become additional MSCs.
Current Maximum MSC Used for Maternity Benefits
The current SSS contribution schedule allows contributions on an MSC of up to ₱35,000. However, this does not mean that the maternity benefit is computed using a ₱35,000 MSC.
Under the current SSS rules, regular SSS benefits use a maximum MSC of ₱20,000. Contributions attributable to an MSC above ₱20,000 and up to ₱35,000 go to the Mandatory Provident Fund, now called the MySSS Pension Booster, and do not increase the regular maternity benefit. (Social Security System)
If all six highest qualifying MSCs are ₱20,000:
- Total MSC: ₱120,000;
- Average daily salary credit: ₱120,000 ÷ 180 = ₱666.67;
- Live childbirth benefit: approximately ₱70,000;
- Qualified solo-parent benefit: approximately ₱80,000; and
- Miscarriage or ETP benefit: approximately ₱40,000.
For an employed member, the SSS payment is not always the entire maternity pay. RA 11210 generally requires the employer to pay the salary differential—the difference between the SSS benefit and the employee’s regular wages for the maternity leave period—unless the employer falls within a legally recognized exemption approved under the applicable rules. (Supreme Court E-Library)
When Contributions Must Be Paid
A contribution month appearing inside the correct 12-month period does not automatically count. SSS also considers when the contribution was paid.
The SSS states that only contributions paid before the semester of contingency will be considered. Contributions paid within or after the semester are excluded. (Social Security System)
This is especially important for self-employed, voluntary, non-working spouse, and land-based OFW members.
Example of an on-time payment that may still be too late for maternity eligibility
Suppose a voluntary member is expected to give birth in January 2026.
Her semester begins on October 1, 2025. Her qualifying period ends in September 2025.
Although the ordinary payment deadline for certain September or third-quarter contributions may extend into October, paying after the semester has already begun can prevent those contributions from being considered for the maternity claim. The safer practice is to pay and confirm posting before the first day of the expected semester.
SSS payment rules generally provide the following deadlines:
| Membership category | General contribution deadline |
|---|---|
| Regular employer | Last day of the month following the applicable month |
| Self-employed, voluntary, or non-working spouse | Last day of the month following the applicable month or calendar quarter |
| Land-based OFW, January to September contributions | December 31 of the same year |
| Land-based OFW, October to December contributions | January 31 of the following year |
However, the semester-of-contingency restriction still applies when determining benefit eligibility. Late retroactive payments by individually paying members are generally not allowed, and missed months normally remain payment gaps. (Social Security System)
Practical Steps Before the Semester Begins
A pregnant SSS member should not wait until delivery to review her records.
- Check the expected quarter of delivery. Determine when the likely semester will begin.
- Log in to My.SSS. Review the actual posted contribution months, not only receipts or payroll deductions.
- Identify the preliminary 12-month period. Use the quarter table above.
- Count qualifying contributions. Confirm that at least three are posted.
- Check the MSC for every posted month. A posted contribution may have a lower MSC because of an underpayment or incorrect employer report.
- Pay eligible individual contributions before the semester begins. Use a Payment Reference Number and keep the payment confirmation.
- Submit the maternity notification. An employed member notifies her employer, while a self-employed, voluntary, non-working spouse, or OFW member may notify SSS through My.SSS, the SSS Mobile App, or an available SSS service channel.
- Enroll a valid disbursement account. SSS releases approved individual benefits through an account enrolled in the Disbursement Account Enrollment Module. (Social Security System)
A maternity notification is important, but its acceptance does not by itself guarantee payment. SSS will still verify the contribution requirements and supporting records.
What to Do If Employer Contributions Are Missing
An employee may discover that contributions deducted from her salary were not posted or were reported under the wrong amount.
She should immediately collect:
- Payslips showing SSS deductions;
- Employment contract or appointment records;
- Payroll summaries, if available;
- Screenshots or printouts of the My.SSS contribution record;
- Maternity notification records;
- Emails or written communications with HR or payroll; and
- Proof of her actual salary.
RA 11210 makes the employer liable for damages equivalent to the benefit the member would otherwise have received when the employer failed to remit the required contributions or failed to transmit the pregnancy notification to SSS. (Supreme Court E-Library)
The member should first request a written correction from the employer and coordinate with the nearest SSS branch or the SSS hotline. A dispute concerning the grant of the SSS maternity benefit falls under the Social Security Commission, while a dispute concerning the employer-paid salary differential may be brought to the appropriate DOLE Field, Provincial, or Regional Office. (Supreme Court E-Library)
Documents Commonly Needed for the Claim
The exact supporting documents depend on the contingency, employment status, and place where the event occurred.
| Situation | Common supporting document |
|---|---|
| Live birth filed within six months | Registered Certificate of Live Birth from the Local Civil Registrar, with applicable receipt or acknowledgment |
| Live birth filed after six months | PSA-issued Certificate of Live Birth |
| Stillbirth or fetal death | Registered or PSA-issued Certificate of Fetal Death |
| Miscarriage or ETP | Proof of pregnancy, proof of termination, and medical records signed by the physician |
| Qualified solo parent | Valid Solo Parent ID or eligibility certification issued through the LGU |
| Childbirth abroad | Report of Birth or equivalent foreign civil record, with English translation when applicable |
Current SSS instructions state that foreign supporting documents generally do not require Philippine consular authentication, foreign notarization, or an apostille for the maternity claim, although an English translation may be required. Documents should be clear, complete, and consistent with the member’s SSS record. (Social Security System)
Maternity Benefit Applications and employer reimbursement applications are generally filed online through My.SSS. Claims may be filed within 10 years from the date of childbirth, miscarriage, or emergency termination of pregnancy, although early filing usually makes it easier to obtain civil-registry and employment records. (Social Security System)
Common Semester-of-Contingency Mistakes
Counting only six or 12 months before childbirth
The correct process is not simply to count backward from the delivery month. First exclude the semester, then count the preceding 12 months.
Using the expected delivery date as final
The expected date is useful for planning, but the actual quarter of childbirth determines the final coverage period.
Paying contributions after the semester starts
A contribution may relate to a month inside the qualifying period but still be excluded if it was paid only after the semester began.
Assuming three contributions produce the maximum benefit
Three contributions may establish minimum eligibility. The amount still depends on the total of the six highest qualifying MSCs.
Assuming all contributions up to ₱35,000 MSC increase maternity pay
Regular maternity benefit computation remains capped at the regular SSS benefit MSC, currently ₱20,000. Amounts above that level are allocated to the provident fund program. (Social Security System)
Looking only at receipts instead of posted records
Payment receipts are important, but the member should verify that the payment was correctly posted under the proper month, membership category, and MSC.
Assuming twins or triplets produce multiple benefits
SSS pays one maternity benefit per childbirth or delivery, regardless of the number of babies delivered. (Social Security System)
Frequently Asked Questions
What is the semester of contingency for an August 2026 delivery?
The semester is April to September 2026. The qualifying contribution period is April 2025 to March 2026.
What is the qualifying period for a May 2026 delivery?
A May delivery falls in the second quarter. The semester is January to June 2026, and the qualifying period is January to December 2025.
Do the three required contributions have to be consecutive?
No. They may be nonconsecutive, provided they fall within the correct 12-month qualifying period, were properly paid, and are recognized under SSS rules.
Can I pay three missed contributions after learning that I am pregnant?
You may pay only contributions that are still legally payable under the rules for your membership category. Individually paying members generally cannot pay missed months retroactively. Even when an ordinary payment deadline has not expired, payment made within or after the semester of contingency may not be counted for the maternity claim. (Social Security System)
Do contributions paid during the semester count?
No. SSS states that contributions paid within or after the semester of contingency are not considered in determining the benefit. (Social Security System)
What happens if I have only three qualifying contributions?
You may meet the minimum contribution requirement, but the benefit will normally be lower because the computation can include only the MSCs attached to your posted qualifying contributions.
Is the benefit higher for a caesarean delivery?
Not under the current Expanded Maternity Leave Law. Both normal and caesarean live deliveries receive 105 days, subject to the same SSS computation. (Supreme Court E-Library)
What is the maximum SSS maternity benefit under the current MSC cap?
Assuming six qualifying months at the ₱20,000 regular-benefit MSC cap, the SSS portion is approximately ₱70,000 for 105 days, ₱80,000 for a qualified solo parent’s 120 days, or ₱40,000 for a 60-day miscarriage or ETP claim.
What if I deliver in a different quarter from my expected due date?
Recompute the semester using the actual delivery date. Crossing a March 31, June 30, September 30, or December 31 quarter boundary moves the 12-month qualifying period by three months.
What if my employer deducted SSS contributions but did not remit them?
Keep your payslips and contribution records, report the discrepancy to the employer and SSS, and request correction. RA 11210 provides employer liability when failure to remit required contributions causes the member to lose maternity benefits. (Supreme Court E-Library)
