BIR Form 1701Q Q3 2026: Deadline, Computation, and Filing Guide

If you are self-employed, a freelancer, a professional in private practice, or a sole proprietor in the Philippines, the end of September means another important tax period is closing. 

The third quarter of 2026 ends on September 30, and qualified individual taxpayers must file BIR Form 1701Q, or the Quarterly Income Tax Return for Individuals, Estates and Trusts. 

The Q3 income tax filing deadline may still seem far away, but it is better to start preparing early. Waiting until the due date to organize your Q3 transactions, collect your BIR Form 2307 certificates, and verify the figures carried forward from your Q1 and Q2 returns can turn a straightforward filing into a rushed one. 

Here is what you should know before filing your Q3 return. 

BIR Form 1701Q is filed for the first, second, and third quarters of the taxable year. The taxpayer's total annual income and tax payments are then reported and reconciled in the applicable annual income tax return, which determines the taxpayer's final income tax liability.  

BIR Form 1701Q is the quarterly income tax return used by individuals earning income from business or the practice of a profession, as well as certain estates and trusts. 

The return is used to report income and determine the taxpayer's income tax due for the quarter, taking into account taxable income from previous quarters and applicable tax credits or payments. The computation is based on the taxpayer's cumulative taxable income for the year to date. 

If you are still in the registration stage, our guide to how self-employed individuals should register with the BIR explains when registration is required and what comes after registration.  

Employees who earn purely compensation income do not file BIR Form 1701Q because they do not have income from a trade, business, or practice of a profession. Depending on their circumstances, their compensation income may be covered by substituted filing or reported in an annual income tax return. 

Likewise, taxpayers whose income consists solely of income subject to final withholding tax, or who are exempt from income tax under the Tax Code or other applicable laws, generally do not file an income tax return on the basis of that income.

Regular deadline for quarterly income tax returns is as follows: 

Under the BIR's prescribed filing schedule, BIR Form 1701Q is due on November 15 following the close of the third quarter, as reflected in the BIR 2026 Tax Calendar. For 2026, however, November 15 falls on a Sunday. The deadline therefore falls on the next working day, Monday, November 16, 2026. 

Taxpayers should still monitor future BIR advisories in case the Bureau announces any deadline changes. 

Check the official Bureau of Internal Revenue website 

Not exactly. 

Although the third-quarter return covers the period from July 1 to September 30, 2026, the income tax computation in BIR Form 1701Q is cumulative for the taxable year. 

The form takes into account the taxpayer's year-to-date taxable income, including amounts from previous quarters. It also considers applicable tax payments and creditable withholding taxes from earlier quarters when determining the amount of income tax still payable.  

This means your Q3 return should not be treated as a standalone calculation based only on July through September transactions. The figures reported should be consistent with your cumulative records from January through September 2026. 

This is why discrepancies in earlier quarters can create problems later. If your books and previously filed returns no longer agree, review Accountable PH’s guide on what happens if your books don't match your filed tax return before simply carrying the numbers forward.  

This is an easy mistake to make. 

Being eligible for the 8% income tax rate does not mean that a taxpayer can wait until the third quarter and choose the 8% option after seeing which calculation produces a lower tax. 

The taxpayer must properly elect the 8% income tax rate within the period prescribed by the BIR. For existing taxpayers, the election is generally made when filing the first quarterly income tax return for the taxable year. Once validly elected, the chosen income tax rate generally applies for the taxable year. 

When preparing the Q3 return, therefore, first confirm which income tax rate was elected earlier in the year. Do not switch between the graduated income tax rates and the 8% income tax rate simply because one produces a lower Q3 or year-to-date tax calculation. 

If a client or customer withheld creditable income tax from payments made to you, you should receive a BIR Form 2307 (Certificate of Creditable Tax Withheld at Source). 

The amount shown on Form 2307 is not an additional tax on top of your income tax liability. It represents income tax already withheld and remitted to the BIR on your behalf and may be claimed as a credit against your income tax due, subject to the applicable rules and supporting documentation. 

This is particularly important when preparing your Q3 return because BIR Form 1701Q includes creditable withholding taxes from previous quarters as well as creditable tax withheld during the current quarter. Your Q3 computation should therefore include applicable withholding tax credits from January through September, not just those reflected on Q3 certificates. 

When claiming creditable withholding taxes, the taxpayer should also prepare the Summary Alphalist of Withholding Taxes (SAWT) and submitted through [email protected]. BIR issuances provides guidelines for SAWT submission in connection with the relevant income tax return and supporting withholding tax credits.  

Do not wait until filing day to ask clients for missing 2307s. Reconcile the certificates against your accounting records first so you do not accidentally claim an unsupported amount or fail to claim a valid tax credit. 

Taxpayers may notice that older BIR forms and regulations refer frequently to “gross sales or gross receipts.” 

The Ease of Paying Taxes Act changed this treatment. Under Revenue Regulations No. 3-2024, BIR now uses gross sales for both sale of goods and services. The EOPT changes also shifted the recognition of service sales from a cash-based to an accrual-based approach for these tax purposes.  

The EOPT reforms also introduced the Invoice as the principal sales document for both goods and services, replacing the previous distinction between sales invoices and official receipts for these purposes. 

Because Form 1701Q was originally issued before those EOPT changes, some of its wording still reflects the older terminology. 

A zero tax payable does not automatically mean there is no filing obligation. 

For example, your deductions and credits may reduce the amount payable to zero, or your business may have had little or no activity during the quarter. If you remain registered for and required to file Form 1701Q, you still need to submit the applicable return by the deadline. 

The BIR's electronic-filing guidance expressly provides procedures for “No Payment” returns, including electronic submission through eBIRForms where applicable.  

This distinction matters because filing the return and paying tax are separate compliance requirements. 

It depends on your tax status and the income tax option you elected. 

If you are eligible for and properly elected the 8% income tax rate, the 8% tax applies in lieu of the graduated income tax on your business or professional income and the 3% percentage tax under Section 116. 

In that case, you generally do not file a separate Form 2551Q for percentage tax while you remain validly covered by the 8% option. 

Late filing or payment can result in surcharges, interest, and applicable compromise penalties. 

The Ease of Paying Taxes Act introduced special concessions for taxpayers classified as Micro and Small, including a reduced civil penalty rate of 10% under Section 248 and a 50% reduction in the applicable interest under Section 249, subject to the law and implementing rules.  

However, the best strategy is still to file accurately and on time rather than rely on reduced penalties after the deadline. 

One important thing to remember: BIR Form 1701Q is filed only for the first three quarters of the year. 

There is no separate Q4 Form 1701Q. Instead, income and expenses from October through December are included in the taxpayer's annual income tax return, which reconciles the full year's income, allowable deductions, tax payments, and applicable tax credits.

The November 16 filing date may make Q3 income tax feel like a November task. 

It is not. 

The numbers you eventually report on Form 1701Q come from the records you build throughout the quarter. Missing invoices, unreconciled bank transactions, incorrect expense entries, missing BIR Form 2307 certificates, and differences between your books and previously filed returns are easier to resolve before the filing deadline gets close. 

By the time Q3 ends on September 30, your goal should be to have your books substantially updated and know what documents are still missing. 

That gives you time to fix the records instead of fixing the return after it has already been filed. 

Accurate tax filing starts with accurate books.

The regular Q3 deadline is November 15. Because November 15, 2026 falls on a Sunday, the 2026 filing and payment date is November 16, 2026.  

A freelancer registered as a self-employed individual or professional files quarterly income tax returns when required under their BIR registration and applicable tax rules. The obligation is not limited to formally licensed professions.  

Having no tax payable does not by itself remove an existing filing obligation. If you are required to file Form 1701Q, a no-payment return may still need to be submitted electronically.  

No. The BIR's instructions state that compensation income need not be reported in the quarterly income tax return. It is reported through the annual income tax return. Your business or professional income is the portion relevant to 1701Q.  

A purely self-employed individual or professional using the qualified 8% option gets the ₱250,000 reduction. A mixed-income earner does not deduct the ₱250,000 from the business income subject to the 8% option.  

Generally, no. The 8% income tax rate must be properly elected within the applicable period, generally when filing the first quarterly income tax return for the year. You cannot switch to 8% in Q3 simply because it results in a lower tax. 

Yes, valid creditable withholding tax supported by Form 2307 may be credited against income tax due, subject to the applicable BIR requirements. Form 1701Q contains specific fields for those credits.  

No. Form 1701Q covers only the first, second and third quarters. Fourth-quarter activity is reconciled through the applicable annual income tax return.
