A free AI assistant for Philippine taxes and BIR compliance. Ask questions in English or Taglish, compute your taxes with the calculators, and track deadlines — no sign-up needed.

₱3,000,000 in gross sales or receipts over any 12-month period. Above it, VAT registration (12%) is mandatory. At or below it, you're generally non-VAT and pay the 3% percentage tax — unless you elect the 8% income tax option.
The 8% option taxes gross receipts minus ₱250,000 (for purely self-employed) and replaces both income tax and percentage tax. It usually wins when your expenses are low. Graduated rates plus 3% percentage tax can be cheaper when expenses are high. Use our calculator to compare side by side — and note the 8% election is irrevocable for the year.

Get a TIN if you don't have one, file BIR Form 1901 with your Revenue District Office (or online via ORUS), receive your Certificate of Registration (Form 2303), register your books of accounts, and get BIR-registered invoices.
