Filing an income tax return as a mixed-income earner in the Philippines can feel confusing because you are dealing with two worlds at the same time: your salary as an employee and your income from business, freelancing, professional practice, online selling, consulting, commissions, or other side work. The most important thing to know is this: once you earn both compensation income and business or professional income, you generally cannot rely on substituted filing by your employer. You usually need to file your own annual income tax return with the Bureau of Internal Revenue (BIR), report both income sources properly, and claim the correct tax credits.

What is a mixed-income earner in the Philippines?

A mixed-income earner is an individual who earns:

Compensation income — salary, wages, allowances, bonuses, or other taxable benefits from an employer; and
Business or professional income — income from self-employment, freelancing, online work, professional services, sole proprietorship, commissions, rentals treated as business income, or other independent income-generating activities.

Common examples include:

An employee who also accepts freelance graphic design clients.
A teacher who earns salary from a school and also gives paid online tutorials.
A call center employee who operates an online shop.
A company employee who receives professional fees from consulting projects.
A foreign resident working in the Philippines who is employed locally and also earns Philippine-source professional income.
An OFW or Filipino abroad who still has taxable business or professional income connected with the Philippines.

The key point is that your employer’s BIR Form 2316 covers only your compensation income. It does not automatically settle your income tax obligations from your sideline, business, or profession.

Legal basis for income tax filing by mixed-income earners

The main legal basis is the National Internal Revenue Code of 1997, as amended by Republic Act No. 10963, or the TRAIN Law, and Republic Act No. 11976, or the Ease of Paying Taxes Act.

Under Section 24 of the National Internal Revenue Code, individual taxpayers are subject to income tax depending on their classification and source of income. The TRAIN Law amended the individual income tax rates and introduced the 8% income tax option for qualified self-employed individuals and professionals. The full text of Republic Act No. 10963 is available on Lawphil.

BIR Revenue Regulations No. 8-2018 and Revenue Memorandum Order No. 23-2018 explain how the 8% income tax option applies to self-employed individuals, professionals, and mixed-income earners. For mixed-income earners, the important rule is that compensation income remains subject to graduated income tax rates, while the business or professional income may be taxed either under graduated rates or, if qualified and properly elected, the 8% income tax rate.

Republic Act No. 11976, the Ease of Paying Taxes Act, also introduced reforms such as taxpayer classification, simplified processes, and special concessions for micro and small taxpayers. BIR guidance under the Ease of Paying Taxes framework classifies taxpayers based on gross sales, including micro, small, medium, and large taxpayers.

Which BIR form should a mixed-income earner use?

For annual income tax filing, the correct form depends on your taxpayer classification and the BIR form available for the taxable year.

Situation	Usual annual ITR form
Mixed-income earner, general rule	BIR Form 1701
Mixed-income earner classified as micro or small taxpayer, when applicable	BIR Form 1701-MS
Pure compensation earner only	BIR Form 1700, unless qualified for substituted filing
Pure business/professional income only, no compensation income	BIR Form 1701A or other applicable form
Quarterly filing for business/professional income	BIR Form 1701Q

BIR Form No. 1701 is the annual income tax return for individuals, including mixed-income earners, estates, and trusts. BIR Form No. 1701-MS is the annual income tax return for individuals classified as micro or small taxpayers, including those with mixed income, under current BIR guidance.

As of the 2026 filing season for taxable year 2025, the BIR issued RMC No. 20-2026 and later RMC No. 37-2026 to guide taxpayers on the filing of BIR Forms 1701-MS, 1701, and 1701A. RMC No. 37-2026 also included electronic filing of BIR Form No. 1701-MS through the Offline eBIRForms Package 7.9.6. The BIR’s official forms and updates are available through the BIR Forms page and eBIRForms page.

Are mixed-income earners qualified for substituted filing?

Usually, no.

Substituted filing is the system where an employee no longer files an annual income tax return because the employer has already withheld the correct tax and issued BIR Form 2316. This generally applies only to qualified employees earning purely compensation income, usually from one employer during the taxable year, with tax correctly withheld.

A mixed-income earner has income outside employment. Because of that, the employer cannot report and pay tax on the taxpayer’s business or professional income. The taxpayer must file an annual ITR and include the compensation income shown in BIR Form 2316.

Tax options for the business or professional income part

A mixed-income earner has two possible tax treatments for the business or professional income component.

Option 1: Graduated income tax rates

Under the graduated system, your compensation income and your net business or professional income are considered in computing your total income tax.

For taxable year 2023 onward, the individual income tax table under the TRAIN Law is:

Annual taxable income	Income tax due
₱250,000 and below	0%
Over ₱250,000 to ₱400,000	15% of excess over ₱250,000
Over ₱400,000 to ₱800,000	₱22,500 + 20% of excess over ₱400,000
Over ₱800,000 to ₱2,000,000	₱102,500 + 25% of excess over ₱800,000
Over ₱2,000,000 to ₱8,000,000	₱402,500 + 30% of excess over ₱2,000,000
Over ₱8,000,000	₱2,202,500 + 35% of excess over ₱8,000,000

If you choose graduated rates for your business or professional income, you may generally choose between:

Optional Standard Deduction (OSD) — a standard deduction, commonly 40% of gross sales or receipts; or
Itemized deductions — actual deductible business expenses supported by invoices, receipts, books, and records.

If you use graduated rates, you may also have business tax obligations such as percentage tax or VAT, depending on your registration and gross sales or receipts.

Option 2: 8% income tax rate, if qualified

The 8% income tax option is available only if you meet BIR conditions. For mixed-income earners, the 8% applies only to the business or professional income, not to compensation income.

You may generally qualify for the 8% option if:

You are an individual earning from self-employment, business, or practice of profession.
Your gross sales or receipts and other non-operating income do not exceed the VAT threshold of ₱3,000,000.
You are not VAT-registered.
You are not subject to other percentage taxes, except the percentage tax under Section 116 of the Tax Code.
You properly signify your intention to use the 8% tax rate within the period and manner required by BIR rules.

A very common mistake is deducting ₱250,000 again from the business income of a mixed-income earner using the 8% option. For mixed-income earners, the ₱250,000 reduction does not apply to the business or professional income under the 8% option. That ₱250,000 zero-tax bracket is already considered in the graduated tax table applied to compensation income.

Example:

Item	Amount
Annual taxable compensation income	₱600,000
Freelance gross receipts	₱400,000
Tax treatment chosen for freelance income	8%
Tax on freelance income	₱400,000 × 8% = ₱32,000

The ₱400,000 freelance receipts are not reduced by ₱250,000 because the taxpayer is mixed-income, not purely self-employed.

Step-by-step guide to filing an income tax return for mixed-income earners

1. Confirm that you are registered correctly with the BIR

If you are earning business or professional income, you should be registered with the BIR as a self-employed individual, professional, or sole proprietor, as applicable.

Check your Certificate of Registration (COR) for:

Registered tax types;
Registered business activity or profession;
Revenue District Office (RDO);
Filing obligations;
Whether you are non-VAT, VAT, percentage tax, or under another tax classification;
Whether your registration reflects your current activity.

If you started freelancing, selling online, or accepting paid professional work without registration, your annual ITR may not be the only issue. You may also need to address registration, invoicing, books of accounts, and open-case concerns.

2. Determine your taxpayer classification

Under the Ease of Paying Taxes system, business taxpayers are classified by gross sales:

Classification	Gross sales
Micro taxpayer	Less than ₱3,000,000
Small taxpayer	₱3,000,000 to less than ₱20,000,000
Medium taxpayer	₱20,000,000 to less than ₱1,000,000,000
Large taxpayer	₱1,000,000,000 and above

This classification matters because micro and small taxpayers may have simplified forms, reduced penalties, and other concessions under BIR regulations.

3. Choose between graduated rates and the 8% tax option

Before filing, decide how your business or professional income will be taxed.

Use the 8% option if you are qualified and it is more practical for your situation. It is simpler because it is based on gross receipts or sales and is in lieu of percentage tax under Section 116. However, you cannot deduct expenses.

Use graduated rates if your deductible expenses are substantial or if you are not qualified for 8%. Under graduated rates, you may use OSD or itemized deductions, but you must maintain proper records.

A practical way to compare:

Factor	8% option	Graduated rates
Basis	Gross sales/receipts and other non-operating income	Net taxable income
Expense deduction	Not allowed	Allowed through OSD or itemized deductions
Percentage tax	Generally in lieu of percentage tax under Section 116	May still apply if non-VAT
Best for	Low-expense freelancers or professionals	Businesses with significant expenses
Available to VAT taxpayers?	No	Yes, if applicable

4. Gather your documents

Before preparing the return, gather all documents. Missing documents are one of the main reasons mixed-income earners file late or claim the wrong tax credits.

Document	Why it matters
BIR Form 2316 from employer	Shows compensation income and tax withheld
BIR Form 2307 from clients	Supports creditable withholding tax claims
Books of accounts	Supports sales, receipts, expenses, and deductions
Sales invoices or official invoices	Supports reported gross income
Quarterly ITRs, BIR Form 1701Q	Needed to compute prior payments and credits
Percentage tax or VAT returns, if applicable	Confirms related business tax compliance
eBIRForms or eFPS confirmations	Proof of filing
Payment confirmations or bank validation	Proof of payment
Financial statements or audited financial statements, if required	Required attachment for certain taxpayers
SAWT, if claiming withholding tax credits	Required summary attachment for tax withheld claims

For employees, employers usually issue BIR Form 2316 after year-end. If you had two employers during the year, gather both forms. If you had freelance clients who withheld tax, ask for BIR Form 2307 for each period.

5. Prepare your quarterly income tax returns

Mixed-income earners with business or professional income generally file BIR Form 1701Q for the first three quarters.

For calendar-year taxpayers, the usual deadlines are:

Quarter	Period covered	Deadline
1st quarter	January to March	May 15
2nd quarter	April to June	August 15
3rd quarter	July to September	November 15

The annual ITR then summarizes the full taxable year and takes into account quarterly income tax payments, withholding tax credits, and other allowable credits.

6. Compute your annual income tax

The computation depends on the tax option chosen.

For the 8% option, the compensation income is taxed using graduated rates, while the business or professional income is taxed at 8% of gross receipts or sales, without the ₱250,000 deduction for mixed-income earners.

For graduated rates, your compensation income and net business/professional income are combined for purposes of the graduated tax computation. You then apply tax credits such as:

Tax withheld by employer, shown in BIR Form 2316;
Creditable withholding tax from clients, shown in BIR Form 2307;
Prior quarterly income tax payments from BIR Form 1701Q;
Excess credits from prior years, if validly carried over.

7. Fill out the correct annual ITR form

Use the applicable BIR form:

BIR Form 1701 for mixed-income earners under the general annual ITR form;
BIR Form 1701-MS if you are a micro or small taxpayer and the form applies to your taxable year;
Avoid using BIR Form 1701A if you have compensation income, because 1701A is generally for individuals earning purely from business or profession.

Be careful with the taxpayer type or alphanumeric tax code fields. Selecting the wrong taxpayer type can cause BIR validation issues, wrong tax computation, or future open cases.

8. File electronically or through the applicable BIR procedure

Most taxpayers now file through BIR electronic platforms:

eFPS — for taxpayers required or enrolled to use the Electronic Filing and Payment System;
Offline eBIRForms Package — commonly used by non-eFPS taxpayers;
Manual filing — only when allowed by BIR issuances, system unavailability, or when the applicable form is not available electronically.

For the 2026 filing season, BIR RMC No. 37-2026 included BIR Form No. 1701-MS in the Offline eBIRForms Package 7.9.6. Because BIR form availability changes, it is important to use the latest official BIR version for the taxable year being filed.

9. Pay the tax due

If your return shows tax payable, payment may be made through available BIR payment channels, such as:

eFPS-authorized agent bank, for eFPS filers;
BIR ePayment gateways;
Authorized Agent Banks;
Other BIR-authorized electronic payment channels.

For taxable year 2025, BIR RMC No. 30-2026 extended the filing, payment, and submission deadline for 2025 annual income tax returns from April 15, 2026 to May 15, 2026. The ordinary statutory deadline for calendar-year individual annual ITRs remains April 15 of the following year, unless the BIR issues a specific extension.

10. Submit required attachments through eAFS, if applicable

If your return has required attachments, such as audited financial statements, SAWT, BIR Form 2307, or other supporting documents, these may need to be submitted through the BIR’s Electronic Audited Financial Statements (eAFS) system.

Under BIR annual filing guidance, attachments are generally submitted electronically through eAFS within the period stated in the applicable revenue memorandum circular. Keep the Transaction Reference Number or confirmation receipt as proof of submission.

Common mistakes mixed-income earners make

Using the employer’s BIR Form 2316 as if it covers everything

BIR Form 2316 covers compensation income. It does not report your freelance, business, professional, or online selling income.

Choosing 8% but still deducting expenses

The 8% option is based on gross receipts or sales. You do not deduct rent, internet, supplies, equipment, transportation, or other expenses.

Deducting ₱250,000 from business income despite being mixed-income

This is one of the most common errors. For mixed-income earners under the 8% option, the business or professional income is generally taxed at 8% of gross receipts or sales without the ₱250,000 deduction.

Claiming withholding tax without BIR Form 2307

If a client withheld tax, you need proper supporting documents. Without BIR Form 2307 and the required summary attachment, the claimed tax credit may be questioned.

Forgetting percentage tax when using graduated rates

If you are non-VAT and choose graduated income tax rates, you may still need to file percentage tax returns, usually BIR Form 2551Q, unless an exemption applies.

Filing only the annual return and ignoring quarterly returns

The annual return does not erase missed quarterly obligations. Missed BIR Form 1701Q filings can appear as open cases.

Not updating BIR registration

If your COR still reflects old tax types, old business activity, or an inactive registration, filing may become more complicated. Registration issues are often discovered only when the taxpayer needs a tax clearance, loan, visa document, or business closure.

Practical scenarios

Employee with a small freelance sideline

If you are employed and earned ₱150,000 from freelance projects during the year, you are a mixed-income earner. If registered and qualified for 8%, your freelance income may be taxed at 8% of the gross receipts. Your salary remains subject to graduated rates through employer withholding.

Employee with an online shop

If you sell products online while employed, your online shop income is business income. You need to track gross sales, cost records, invoices, books, and applicable business taxes. If your sales grow beyond the VAT threshold, the 8% option will no longer be available.

Employee with two employers and freelance work

You need to gather BIR Form 2316 from each employer and include your freelance income. This is not a substituted filing situation. The annual ITR should consolidate the taxable information.

Foreigner employed in the Philippines with side consulting

A foreigner may have Philippine tax obligations depending on residence, source of income, and whether the work is performed in the Philippines. For services, the place where the services are performed is often important in determining source. A foreign client does not automatically make the income foreign-source if the work is performed in the Philippines.

Filipino abroad with Philippine business income

A non-resident citizen is generally taxed on income from sources within the Philippines. If the Filipino abroad continues to earn Philippine business, rental, or professional income, Philippine tax filing may still be required.

Required documents checklist

Before filing, prepare:

BIR Certificate of Registration;
TIN and registered RDO information;
BIR Form 2316 from employer or employers;
BIR Form 2307 from clients or withholding agents;
Sales invoices or official invoices;
Books of accounts;
List of gross receipts or sales for the year;
Expense records, if using graduated rates with deductions;
Quarterly BIR Form 1701Q returns;
Percentage tax or VAT returns, if applicable;
Prior-year excess tax credits, if claimed;
SAWT, if claiming creditable withholding tax;
Financial statements or audited financial statements, if required;
eBIRForms, eFPS, payment, and eAFS confirmations.

Deadlines to remember

Filing or payment	Usual deadline
BIR Form 1701Q, 1st quarter	May 15
BIR Form 1701Q, 2nd quarter	August 15
BIR Form 1701Q, 3rd quarter	November 15
Annual ITR for calendar-year individual taxpayers	April 15 of the following year
Percentage tax, if applicable	Generally within 25 days after the close of each taxable quarter
eAFS attachments	Based on the applicable BIR annual filing circular

If the deadline falls on a weekend, holiday, or the BIR issues a special extension, the applicable deadline may change. For taxable year 2025, the BIR extended the annual ITR filing, payment, and attachment submission deadline to May 15, 2026 under RMC No. 30-2026.

Penalties for late or incorrect filing

Late filing, late payment, or non-filing may lead to:

Surcharge;
Interest;
Compromise penalties;
Open cases in the BIR system;
Difficulty securing tax clearance;
Problems when closing a business registration;
Issues when using ITRs for loans, visas, immigration, scholarships, or government transactions.

The general civil penalty for failure to file and pay on time is commonly 25% of the amount due, plus interest and possible compromise penalties. Under Revenue Regulations No. 6-2024 implementing the Ease of Paying Taxes Act, qualified micro and small taxpayers may be entitled to reduced penalties, including a 10% civil penalty in covered cases and reduced interest.

Even if your tax due is zero, a missed required return can still create an open case. This is why registered mixed-income earners should file required returns even during periods with no operations or no tax payable.

Frequently Asked Questions

Do mixed-income earners need to file an annual ITR?

Yes. If you earn both compensation income and business or professional income, you generally need to file an annual income tax return. Your employer’s BIR Form 2316 does not cover your freelance, business, or professional income.

What BIR form should I use if I am employed and freelancing?

Most mixed-income earners use BIR Form 1701. If you are classified as a micro or small taxpayer and BIR Form 1701-MS applies for the taxable year, you may use BIR Form 1701-MS. BIR Form 1701A is generally for individuals earning purely from business or profession, not those with employment income.

Can a mixed-income earner choose the 8% tax rate?

Yes, if qualified. Your business or professional income must not exceed the VAT threshold, you must not be VAT-registered, and you must properly elect the 8% option. Your salary remains taxed under graduated income tax rates.

Can I deduct ₱250,000 from my freelance income if I am also employed?

No, not under the 8% option for mixed-income earners. The ₱250,000 zero-tax bracket is already part of the graduated tax table applied to compensation income. For mixed-income earners, the 8% generally applies to the full gross business or professional receipts.

Do I still need to file BIR Form 1701Q?

Yes, if you are registered as earning business or professional income. BIR Form 1701Q is filed for the first three quarters, and the annual ITR summarizes the full year.

What if my employer already withheld tax from my salary?

You still include the compensation income in your annual ITR and claim the tax withheld as a credit. The withholding shown in BIR Form 2316 helps reduce your final tax due, but it does not replace your obligation to report business or professional income.

What if my client withheld tax and gave me BIR Form 2307?

You may claim the amount as creditable withholding tax, provided it is properly supported and included in the required attachment, such as SAWT. Keep the original or digital copies of BIR Form 2307.

Can I file even if I have no tax payable?

Yes. If you are required to file, you should file even if the result is zero tax payable. Filing prevents open cases and preserves your compliance record.

Are foreign clients taxable in the Philippines?

The client’s location is not the only factor. For services, the place where the services are performed is often important. A Philippine resident performing services in the Philippines for a foreign client may still have Philippine tax obligations.

What happens if I forgot to register my sideline income?

You may need to address BIR registration, invoicing, books of accounts, and missed filings. Filing the annual ITR alone may not fix all compliance issues if the business or professional activity was never properly registered.
