If you earn a regular salary from a job while also making money from freelance work, consulting, online gigs, content creation, or a small side business, you are a mixed income earner in the eyes of the Bureau of Internal Revenue (BIR). Your employer withholds and remits taxes only on your compensation income through the BIR Form 2316, but you remain responsible for reporting your total income from all sources and settling any additional tax due on the combined amount. Filing your own annual Income Tax Return (ITR) consolidates everything accurately. This guide explains exactly how to prepare and file your ITR online as a mixed income employee and freelancer in the Philippines using the BIR’s electronic systems.

Who Needs to File as a Mixed Income Earner

You must file your own annual ITR if you have both compensation income (from employment) and income from trade, business, or the practice of a profession (freelance, professional fees, commissions, or business receipts). This applies even if your freelance income is modest or your employer already withholds taxes correctly on your salary.

The employer’s withholding covers only the salary portion. Your total taxable income — salary plus net freelance or business income after allowable deductions — determines your final tax liability under the graduated rates (or the 8% flat rate option on the business portion if you qualify). Filing your own return ensures the correct tax is paid or any over-withholding is refunded.

Pure compensation earners whose tax withheld exactly equals their tax due and who meet certain conditions may be exempt from filing their own ITR. Once you add freelance or business income, that exemption generally no longer applies.

Legal Basis and Key Obligations

Section 51 of the National Internal Revenue Code (NIRC) of 1997, as amended, requires individuals engaged in trade or business or the practice of a profession — including those with mixed income — to file an annual ITR regardless of the amount of gross income. Revenue Memorandum Circulars (such as RMC No. 20-2026 and RMC No. 37-2026) provide the current guidelines and forms for calendar year 2025 income filed in 2026. The Ease of Paying Taxes Act (Republic Act No. 11976) introduced simplified options like BIR Form 1701-MS to reduce compliance burden for smaller taxpayers.

You are also required to file quarterly income tax returns (BIR Form 1701Q) for the business or professional income portion and to pay any tax due on that income throughout the year. Your annual return then reconciles everything.

Choosing the Right Form: BIR Form 1701 or 1701-MS

Two main forms apply to mixed income earners:

Form	Who Should Use It	Key Features	Best For
BIR Form 1701	Individuals engaged in trade/business/profession with mixed income (compensation + business), any gross sales amount	Full schedules, supports multiple tax rates, detailed deductions	Most mixed income earners, especially those with complex deductions or larger business income
BIR Form 1701-MS	Micro taxpayers (gross sales/receipts < ₱3 million) or small taxpayers (₱3 million to < ₱20 million) with mixed income who prefer a simplified return	Simplified 2-page form, single income tax rate on business income portion	Smaller mixed income earners seeking easier filing and compliance

Both forms can be filed electronically. If your business or freelance gross sales/receipts fall below ₱20 million and you are subject to a single tax regime on the business portion (graduated rates, 8% flat rate, or exempt), you may choose the simpler 1701-MS. Otherwise, or if you need more detailed reporting, use Form 1701. Check the form instructions or BIR resources to confirm which fits your situation best.

Important Preparations Before You File Online

Update your BIR registration if needed. If you started freelancing or any business activity while employed, update your registration status to “mixed income earner” through the BIR’s Online Registration and Update System (ORUS) at orus.bir.gov.ph or at your Revenue District Office (RDO). This ensures your Certificate of Registration reflects the correct activity and avoids issues with filing under the wrong category.
File your quarterly returns. For the freelance or business portion, file BIR Form 1701Q and pay any tax due on or before May 15 (Q1), August 15 (Q2), and November 15 (Q3). The annual reconciliation happens in April of the following year.
Obtain your BIR Form 2316. Request this Certificate of Compensation Payment and Tax Withheld from your employer(s) as early as possible (usually available by late January or early February). It shows your gross compensation, taxable compensation, and taxes already withheld.
Organize your freelance or business records. Keep summaries of gross receipts/sales, cost of sales or services, and deductible expenses (or decide whether to claim the Optional Standard Deduction of 40% of gross sales/receipts or the 8% flat rate on gross sales/receipts if your business gross receipts did not exceed ₱3 million in the prior year). Gather any BIR Form 2307 certificates if clients withheld tax on your fees.

Step-by-Step Guide to Filing Your ITR Online via eBIRForms

The BIR requires most individual taxpayers, including those with no tax due, to file electronically. Non-eFPS filers use the offline eBIRForms Package (latest version, such as 7.9.6 or newer).

Go to the official BIR website (bir.gov.ph) and download the latest eBIRForms Package from the eBIRForms section.
Install the software on your computer (it typically runs on Windows). Follow the installation prompts.
Open the eBIRForms application and set up or load your taxpayer profile using your Taxpayer Identification Number (TIN), registered name, address, and other details.
Select the correct annual return for the taxable year (e.g., BIR Form 1701 or 1701-MS for income earned in 2025).
Complete the form fields carefully:
- Indicate your filing status and mark the appropriate box for Mixed Income.
- Enter compensation income and tax withheld details directly from your BIR Form 2316.
- Report your freelance or business gross sales/receipts, cost of sales/services, and allowable deductions (itemized or Optional Standard Deduction). If eligible, indicate the 8% flat rate option for the business portion.
- Include any other income, tax credits, and payments already made through quarterly filings.
- The software automatically computes tax due or overpayment based on your inputs.
Validate the form. The system will flag missing or inconsistent information.
Generate and submit the return electronically through the eBIRForms facility. You should receive a system-generated confirmation (often via email) as proof of successful filing. Take a screenshot of any pop-up confirmation message as backup.
If tax is still due after consolidation, pay it promptly through authorized ePayment gateways, online banking with BIR reference, or authorized agent banks. Reference your filed return number.
Download or save a copy of the filed return and confirmation email. Keep all supporting documents (2316, records of freelance income/expenses, quarterly filings) for at least three years.

The eBIRForms software includes validation rules and on-screen guidance. For field-specific instructions, refer to the latest form guide available on the BIR website or official instructional materials.

Required Documents, Timelines, and Offices

Core documents checklist:

BIR Form 2316 from each employer
Summary of freelance/business gross receipts, sales, and deductible expenses (or proof supporting OSD or 8% election)
Copies of quarterly BIR Form 1701Q filed and proof of payment
BIR Form 2307 (if any withholding on freelance fees)
Valid government-issued ID and TIN records
Bank account details (for refunds)

Key timelines (for calendar year taxpayers):

Quarterly 1701Q: May 15, August 15, November 15
Annual ITR (1701 or 1701-MS): Generally on or before April 15 of the following year (BIR may announce extensions — always verify the exact date on bir.gov.ph)
Employer issues 2316: Usually by January 31 or shortly after

Most filing happens online through eBIRForms. Registration updates or corrections are handled via ORUS or your RDO. No filing fee applies for the return itself, but any tax due plus penalties (if late) must be paid.

Common Pitfalls and Real-Life Scenarios

Many mixed income earners encounter these issues:

Failing to update BIR registration. Starting freelance work without updating your status can lead to filing under the wrong category and potential penalties for incorrect returns.
Treating the employer’s 2316 as the complete picture. Your salary withholding does not automatically cover tax on freelance income. You must consolidate and pay any shortfall on total taxable income.
Skipping or delaying quarterly filings. Penalties on the business portion accumulate quickly and appear when you file the annual return.
Underreporting freelance income or poor record-keeping. BIR matching systems and audits can catch discrepancies between declared income and third-party data (e.g., from platforms or clients).
Last-minute filing. System congestion near the deadline increases the chance of errors or failed submissions.

Example scenario: An employee earning ₱600,000 in taxable compensation (with taxes already withheld) adds ₱250,000 in net freelance income after deductions. The annual ITR consolidates both, recomputes the total tax under graduated rates (or applicable regime), and determines whether additional payment or a refund is due. Proper filing avoids surprises and keeps records clean.

Frequently Asked Questions

Do I still need to file my own ITR if my employer withholds taxes and my freelance income is small?
Yes. Mixed income earners must file BIR Form 1701 or 1701-MS to report all income sources and settle the correct total tax liability. The employer’s withholding covers only compensation.

Which form should I use if I have both salary and freelance income?
Use BIR Form 1701 (general mixed income form) or BIR Form 1701-MS if you qualify as a micro or small taxpayer (business gross sales/receipts below ₱20 million) and prefer the simplified version.

Can I file completely online even with mixed income?
Yes. Download and use the latest eBIRForms Package to prepare and submit your return electronically. You will receive confirmation of successful filing.

What if I started freelancing mid-year — do I need to do anything special?
Update your BIR registration to mixed income status as soon as possible through ORUS or your RDO. File quarterly returns for the business portion from the time it began and consolidate everything in the annual ITR.

How are deductions handled for the freelance part in a mixed income return?
You may claim actual expenses or the Optional Standard Deduction (40% of gross sales/receipts) for the business portion. If eligible, you may also opt for the 8% flat rate on gross sales/receipts of the business income. The form guides you on the applicable regime.

What happens if I file late?
You face a surcharge (25% or 50% depending on circumstances), interest on unpaid tax, and possible compromise penalties under the NIRC. File as soon as you can and pay any tax due to minimize additional charges.

Do I need to file quarterly taxes for my freelance income even if I file the annual return?
Yes. Quarterly filing (BIR Form 1701Q) is required for the business or professional income portion. The annual return reconciles the full year.

Can I get a tax refund as a mixed income earner?
Yes, if total taxes withheld or paid (including quarterly payments) exceed your final tax liability after consolidation. The eBIRForms system computes this, and refunds are processed through BIR channels.

Is there help available if the form looks complicated?
The eBIRForms software has built-in validation and instructions. BIR also releases form guides and instructional materials. For complex computations, many taxpayers use BIR-accredited tax software or seek assistance from licensed professionals familiar with current BIR systems.
