When do I have to register for VAT?

When your gross sales or receipts exceed ₱3 million in any twelve-month period, or when you have reasonable grounds to expect they will. Registration is mandatory from that point; the Tax Code gives only a short window after the end of the month in which you crossed the line, so treat it as immediate and file Form 1905 to add VAT as a tax type.

Is VAT still filed monthly?

No. The monthly Form 2550M was removed starting January 2023 under the TRAIN Law's schedule. VAT-registered businesses file Form 2550Q within 25 days after the end of each quarter, with the quarterly summary lists of sales and purchases.

Can I register for VAT even if I am below ₱3 million?

Yes. Voluntary registration is allowed, usually because your customers are VAT-registered businesses that want input tax on your invoices. Once you opt in, you cannot cancel the VAT registration for the next three years.

What do I pay if I stay non-VAT?

Either 3% percentage tax under Section 116 on gross sales, filed quarterly on Form 2551Q, or, if you are an individual who qualifies, the 8% income tax option, which replaces both the graduated income tax and the percentage tax.

What happens if I cross ₱3 million and don't register?

You become liable for the 12% output VAT on sales made after the threshold was crossed, without the right to claim input tax on purchases, plus surcharge and interest on the unpaid VAT. The BIR can also assess the percentage tax you kept paying as insufficient.

VAT vs Non-VAT: The ₱3 Million Threshold Explained

Whether your business charges 12% VAT or pays 3% percentage tax comes down to one number: ₱3 million in gross sales or receipts over twelve months. Below it you can stay non-VAT; above it you must register for VAT. The line decides your invoices, your quarterly returns, your prices, and whether e-invoicing applies to you.

The two regimes side by side

	Non-VAT	VAT-registered
Who	Gross sales of ₱3 million or less in a twelve-month period, and not voluntarily registered	Gross sales above ₱3 million, or voluntary registrants
Business tax	3% percentage tax on gross sales (Section 116), or the 8% option for qualified individuals	12% VAT on sales, less VAT paid on purchases (input tax)
Return	Form 2551Q, within 25 days after each quarter	Form 2550Q, within 25 days after each quarter
Invoice	Non-VAT invoice marked “VAT-exempt” or “non-VAT”	VAT invoice showing the VAT-able amount, the 12% VAT, and the total
Input tax on purchases	Not recoverable; it is part of your cost	Credited against output VAT
E-invoicing mandate (2026)	Micro taxpayers excluded	May be covered if you sell online or use a computerized accounting system

The threshold is set by Section 109(CC) of the Tax Code, as last raised by the TRAIN Law. Sales that are VAT-exempt by nature (for example, agricultural food products in their original state, or residential rent at or below the exempt ceiling) don’t count towards the ₱3 million.

Reading your own numbers

The test is gross sales or receipts, not profit, over any twelve consecutive months, not just the calendar year. A business that sold ₱1.2 million from July to December and ₱2 million from January to June has crossed the threshold even though neither calendar year did.

Check the trailing twelve months every quarter when you prepare the 2551Q. If the trend says you will cross the line, the Tax Code also treats “reasonable grounds to believe” you will exceed ₱3 million as a trigger, so the safe move is to register before the quarter in which it happens, not after.

Crossing the line: what to do

File Form 1905 through ORUS or at your RDO to add VAT as a tax type and remove percentage tax. Your Certificate of Registration is reissued.
Switch your invoices. Non-VAT invoices can’t be used for VAT sales. Apply for a new Authority to Print, or reconfigure your registered POS or accounting system to show the VAT breakdown.
Reprice or absorb. Your customers now pay 12% on top of the price unless you absorb it. Business customers who are VAT-registered won’t mind; walk-in consumers will notice.
Start keeping input tax records. Every VAT invoice from a supplier is now worth 12% of the purchase as a credit. Receipts without VAT details are lost credits.
Register your books for the new tax type if your RDO asks, and start filing 2550Q from the quarter of registration.

If you were on the 8% income tax option, it ends the moment you cross ₱3 million. You revert to graduated rates for the whole year and pay percentage tax up to the registration date, then VAT from there.

Filing Form 2550Q

VAT is settled quarterly. The monthly 2550M disappeared in January 2023, so the schedule is now:

Quarter	Standard deadline
January to March	April 25
April to June	July 25
July to September	October 25
October to December	January 25

Each return reports output VAT on sales, input VAT on purchases, and the difference payable. Attach the quarterly Summary List of Sales and Summary List of Purchases (and importations, if any) through the BIR’s eSubmission facility. Input tax that exceeds output tax carries forward to the next quarter; it is only refundable in specific cases such as zero-rated sales.

Weekend dates move to the next working day, so the third-quarter 2550Q for 2026 is due Monday, October 26, and the fourth-quarter return is due Monday, January 25, 2027.

Voluntary registration and the three-year lock

Some businesses below ₱3 million register for VAT anyway. The usual reason is customers: a corporate client prefers a VAT invoice because the 12% becomes its input tax, while a non-VAT supplier’s price is a pure cost. Exporters also register to claim zero-rating.

The trade-off is written into Section 236(H) of the Tax Code: once you register voluntarily, you can’t cancel the VAT registration for the next three years, even if sales fall. Run the numbers before you opt in. If most of your customers are consumers, VAT makes you 12% more expensive for no benefit to them.

Dropping back below the threshold

A mandatorily registered business whose gross sales fall to ₱3 million or less for a full twelve months can apply to cancel its VAT registration and return to percentage tax. The request is filed on Form 1905 with proof of the lower sales, and it takes effect from the first day of the month after the cancellation is approved. The lock-in doesn’t apply because the registration wasn’t voluntary.

Common mistakes near the line

Counting only the calendar year. The twelve-month test catches a business that straddles two years.

Issuing non-VAT invoices after crossing. Sales after the threshold are VAT-able whether or not you registered. Unregistered sellers lose the input tax credit and still owe the output VAT.

Forgetting the e-invoicing trigger. The ₱3 million line also separates micro taxpayers, who are excluded from mandatory e-invoicing, from small taxpayers who sell online or use a computerized accounting system and must comply by December 31, 2026. See our guide on invoices and the e-invoicing deadline.

Paying both taxes. Percentage tax stops when VAT starts. A business that keeps filing 2551Q after registering for VAT is paying 3% it doesn’t owe.
