BIR Penalties Explained (2026): Surcharge, Interest & Compromise

What are BIR penalties for late tax filing?

BIR penalties are the additions to tax the Bureau of Internal Revenue imposes when you file or pay a return late, file an incorrect return, or do not file at all. In the Philippines, every late return triggers up to three separate charges that stack on top of the original tax: a surcharge (a percentage of the tax due), interest (an annual rate on the unpaid amount), and a compromise penalty (a flat administrative fine). These are set out in Sections 248 and 249 of the National Internal Revenue Code (NIRC), as amended by the TRAIN Law, and in Revenue Memorandum Order (RMO) No. 7-2015. Understanding how each is computed lets you predict the cost of a late filing and decide whether to file immediately or seek relief.

How much is the BIR surcharge: 25% or 50%?

The surcharge is a one-time penalty equal to 25% of the tax due in ordinary cases of late filing or late payment, and 50% in cases of willful neglect to file or a false or fraudulent return. Under Section 248 of the NIRC, the 25% surcharge applies when you fail to file and pay on the prescribed date, fail to pay a deficiency tax within the time stated in an assessment notice, or fail to pay the full tax shown on your return by the deadline.

The rate jumps to 50% when the failure is willful, when the return is false or fraudulent, or, critically, when the BIR discovers your non-filing before you voluntarily file. This is why tax professionals advise filing on your own initiative even if you are already late: voluntary late filing keeps you at 25%, while waiting for a BIR notice can double the surcharge. For example, if Maria, a freelance graphic designer in Cebu, owes ₱40,000 in income tax and files late on her own, her surcharge is ₱10,000 (25%). If the BIR catches the omission first, it becomes ₱20,000 (50%). Estimate your base tax with our withholding tax calculator or percentage tax calculator before computing penalties.

How is BIR interest computed at 12% per year?

BIR interest is charged at 12% per annum on the unpaid tax, running from the day after the deadline until the date you pay in full. Section 249 of the NIRC, as amended by the TRAIN Law and implemented by Revenue Regulations (RR) No. 21-2018, sets the interest at double the legal interest rate set by the Bangko Sentral ng Pilipinas (BSP), which produces 12% for ordinary taxpayers. A key TRAIN reform: deficiency interest and delinquency interest can no longer both run for the same period after January 1, 2018, so you are not double-charged interest on the same amount.

Interest accrues daily. The formula is: Interest = Unpaid Tax × 12% × (days late ÷ 365). So if Juan, a sari-sari store owner in Quezon City, owes ₱30,000 and pays 90 days late, his interest is ₱30,000 × 12% × (90 ÷ 365) = ₱887.67. Interest is computed only on the basic tax, not on the surcharge or the compromise penalty.

What is the BIR compromise penalty and how much is it?

The compromise penalty is a flat administrative fine the BIR collects in lieu of criminal prosecution for a tax-code violation. It is not a percentage; it is a fixed peso amount that ranges from ₱200 to ₱50,000 under the graduated schedule in RMO No. 7-2015 (Annex A), keyed to the size of the size of the violation (keyed to gross sales, earnings or receipts). Crucially, the compromise penalty can apply even when your tax due is zero, because it attaches to the act of filing late, not to any unpaid balance. A dormant corporation filing a nil annual income tax return after the deadline still owes a compromise penalty.

For late filing of an income tax or VAT return, a common first-offense compromise penalty is around ₱1,000. The graduated schedule rises with the basic tax, illustrated below:

The compromise penalty is technically voluntary: the BIR cannot force you to pay it without your agreement, but declining it generally means the Bureau may pursue the criminal case instead. The amounts above are suggested figures; deviations require approval from the Commissioner, a Deputy Commissioner, or a Regional Director.

Do micro and small taxpayers get reduced BIR penalties?

Yes. Under the Ease of Paying Taxes (EOPT) Act, Republic Act No. 11976, implemented by RR No. 6-2024, micro and small taxpayers pay significantly reduced penalties. A micro taxpayer has gross sales of less than ₱3,000,000 for the taxable year; a small taxpayer has gross sales of ₱3,000,000 to less than ₱20,000,000. These taxpayers benefit from:

• 10% surcharge instead of the usual 25% under Section 248.
• 6% annual interest instead of 12% (a 50% reduction of the Section 249 rate).
• ₱500 compromise penalty for each failure to file an information return, statement, list, or to keep required records.

If you are a freelancer or solo professional earning under ₱3,000,000, you almost certainly qualify as a micro taxpayer and these reduced rates apply. Check whether the 8% flat rate or graduated rates suit you in our 8% vs graduated income tax guide, and see your obligations as a self-employed taxpayer or freelancer.

Worked example: late filing of an income tax return

Let us compute the full penalty for a realistic late filing. Suppose Liza, a self-employed consultant in Davao classified as a regular (non-EOPT) taxpayer, owes ₱100,000 in annual income tax due on April 15, 2026, but files and pays voluntarily 120 days late on August 13, 2026.

Now compare: if Liza instead qualified as a micro taxpayer under the EOPT Act, the surcharge falls to 10% (₱10,000) and interest to 6% (₱1,972.60), cutting her total penalties by more than half. The difference, roughly ₱16,000, shows why classifying your business correctly matters. Before you file, estimate the underlying tax precisely using the income tax calculator, then add the penalties above.

Common mistakes that increase BIR penalties (information gain)

Most penalty overpayments come from avoidable errors. Watch for these:

• Waiting for a BIR notice. The single most expensive mistake. Voluntary late filing keeps the surcharge at 25%; a BIR-discovered non-filing doubles it to 50%. Always file first, even late.
• Forgetting the compromise penalty on zero-tax returns. Filers assume "no tax due, no penalty." Wrong. The compromise penalty attaches to the late filing itself, so a nil quarterly return still costs you.
• Computing interest on the surcharge. Interest runs only on the basic tax, never on the surcharge or compromise penalty. Adding them inflates your estimate and your BIR Form 0605 payment.
• Missing the EOPT reduced rates. Many micro taxpayers pay the full 25% and 12% because they do not know RR 6-2024 entitles them to 10% and 6%. Confirm your classification.
• Amending a return after the deadline. An amended return that increases your tax can itself trigger a 25% surcharge on the additional tax, per BIR practice and Grant Thornton commentary. File correctly the first time.
• Ignoring quarterly deadlines. Penalties apply per return. Missing four quarterly deadlines means four sets of charges. Track them with our quarterly tax deadlines guide.

How do I pay BIR penalties and can they be reduced?

You pay penalties together with the tax using BIR Form 0605 (Payment Form) or as part of the relevant return, at an Authorized Agent Bank, through eFPS/eBIRForms, or via accredited e-payment channels. If you genuinely could not file on time for a valid reason, you may request abatement or cancellation of penalties under RMO No. 20-2007, which the Commissioner may grant for reasonable causes such as a calamity, destruction of records, or BIR system failures. The basic tax itself is rarely abated; relief usually targets the surcharge, interest, or compromise penalty.

To stay compliant going forward, register correctly from the start with our BIR registration guide and freelancer registration walkthrough, then file on time using our how to file your ITR guide. Self-employed taxpayers typically file annually on BIR Form 1701 and quarterly percentage tax on Form 2551Q. Knowing your exact tax in advance, via our salary tax calculator, is the surest way to avoid penalties entirely.
