2551Q Deadline 2026: Every Percentage-Tax Due Date (and How to Skip It)

Missing a 2551Q deadline is one of the most common — and most avoidable — ways online sellers rack up BIR penalties. Import all four 2026 due dates into your calendar below, then read who actually has to file — and how the 8% option lets many sellers skip 2551Q entirely.

The 2026 2551Q deadlines

The percentage tax return (BIR Form 2551Q) is filed quarterly, due 25 days after the end of each quarter:

QuarterCoversDeadline
Q1 2026Jan – Mar 2026Apr 25, 2026Sat — file by Mon Apr 27
Q2 2026Apr – Jun 2026Jul 25, 2026Sat — file by Mon Jul 27
Q3 2026Jul – Sep 2026Oct 25, 2026Sun — file by Mon Oct 26
Q4 2026Oct – Dec 2026Jan 25, 2027
Three of these four land on a weekend in 2026. When that happens the deadline rolls to the next working day under RMC 65-2016(eFPS, eBIRForms and manual filers alike) — that's the second date above. Treat it as a safety net, not a plan: filing on the earlier date is never penalised, and the eBIRForms servers are at their worst on a deadline Monday.

Wait — do you even need to file 2551Q?

This is the part most people miss. You only file 2551Q if you're a non-VAT taxpayer on graduated income tax rates. If you elected the 8% flat option, the 8% already stands in for the 3% percentage tax — so you don't file 2551Q at all. That's one fewer quarterly return, four times a year.

Not sure which option you're on, or which is cheaper? It changes both your tax bill and how many returns you file. The free calculator shows both side-by-side.

Penalties for filing late

Filing 2551Q late isn't free. The BIR generally assesses:

  • 25% surcharge on the amount due (can be 50% for willful neglect or fraud),
  • Interest on the unpaid tax, accruing until paid, and
  • a compromise penalty — a fixed amount that scales with your sales.

These stack per return, so a missed quarter can cost several times the tax itself. Even a zero-sales quarter usually needs a return filed.

How to file 2551Q

  1. Compute your 3% percentage taxon the quarter's gross sales/receipts.
  2. File electronically via eBIRForms (or eFPS if enrolled) and submit the return.
  3. Pay through an authorized channel (GCash, Maya, online banking, or an authorized agent bank) before the deadline.
  4. Keep the confirmation — it's your proof of filing.

Frequently asked questions

＋ When is the 2551Q deadline for 2026?

The quarterly percentage tax return (2551Q) is due 25 days after the end of each quarter: Q1 by April 25, 2026; Q2 by July 25, 2026; Q3 by October 25, 2026; and Q4 by January 25, 2027. Three of those fall on a weekend in 2026, so the actual last day to file is the next working day — Monday April 27, Monday July 27 and Monday October 26 (RMC 65-2016). Filing on the earlier statutory date is always safe.

＋ Do I need to file 2551Q at all?

Only if you are on graduated income tax rates as a non-VAT taxpayer. If you elected the 8% flat income tax option, you do not file 2551Q — the 8% already replaces the 3% percentage tax.

＋ What is the penalty for filing 2551Q late?

Late filing generally triggers a 25% surcharge, plus interest on the unpaid tax, plus a compromise penalty. These stack per return, so filing on time — even a zero return — is far cheaper.

＋ What if I had no sales for the quarter?

You usually still file a return, showing zero. Skipping it entirely because you had no sales can still count as a failure to file and attract penalties.

＋ How do I know if 8% or graduated (with 2551Q) is better?

The 8% option removes the 2551Q filing and is usually cheaper for low-expense businesses. Graduated rates can win when expenses are high. Compute both with the free calculator to see which is lower for your numbers.
