Annual Income Tax Return for individuals engaged in business or practice of profession.
BIR Form 1701 is the annual income tax return filed by self-employed individuals, sole proprietors, professionals (doctors, lawyers, CPAs, freelancers), and mixed-income earners (those with both compensation income and business income). It covers the entire calendar year (January 1 to December 31) and is due on April 15 of the following year.
The 1701 reconciles all income earned during the year — gross sales or receipts, allowable deductions, and any quarterly tax payments already made via BIR Form 1701Q. Creditable withholding taxes evidenced by BIR Form 2307 are also claimed here as tax credits reducing the final tax due.
In practice: Dr. Maria Santos, a dentist in Quezon City, earned ₱2,400,000 in professional fees for 2025. She already paid ₱120,000 through quarterly returns (1701Q) and has ₱48,000 in 2307 tax credits from clinics that withheld tax from her payments. Her final tax due under the graduated rate is computed on net taxable income after deductions, with the ₱168,000 already paid subtracted from the computed tax.
Why it matters: The April 15 deadline is fixed — there is no extension for individual ITRs in the Philippines. Missing it results in a 25% surcharge, 12% annual interest, and compromise penalties. Sole proprietors who fail to reconcile their quarterly payments correctly often either overpay or face a surprise tax bill in April.
Taxpayers who opted for the 8% flat tax rate file 1701A (a simplified version), not the full 1701. Check which form applies based on your tax regime election.
