Compute a return

Your own figures, the same engine a filed return uses — including the dated rule tables, so a past period is computed on the rules that applied then. No account, and nothing you type is stored anywhere.

Not sure which form is yours? Answer four questions — or read the guide.

Elected each year and it lapses — see the guide.

What do these mean?
Graduated rates
The normal income tax table: nothing on the first ₱250,000, then 15% to 35% as income rises. You still owe percentage tax or VAT on top.
OSD
Optional Standard Deduction: a flat 40% of your gross sales taken as expenses, with no receipts to keep and nothing to prove. You give up deducting what you actually spent.
Itemized deductions
You deduct what you actually spent, receipt by receipt. Better than the 40% OSD only if your real expenses come to more than that — and every one needs a valid invoice behind it.
8% flat on gross
8% of your gross sales above ₱250,000, instead of both the graduated income tax and the percentage tax. Needs gross under ₱3M and non-VAT, and it lapses every year unless you elect it again.

What do these mean?
Mixed income
A salary and business or freelance income in the same year. You file 1701, attach your 2316s to it, and the ₱250,000 is not available against the business side.
Taxable compensation
Not your gross pay. It is what remains after your SSS, PhilHealth and Pag-IBIG share and the 13th-month and de minimis exclusions — often six figures lower. Your 2316 shows it as its own line.

VAT-registered means 2550Q, never 2551Q.

What do these mean?
VAT-registered
You charge 12% VAT on sales and file 2550Q each quarter instead of 2551Q. Mandatory once gross sales pass ₱3,000,000, optional below it.
Percentage tax
3% of your quarterly gross receipts, filed on 2551Q. It applies to non-VAT taxpayers — unless you elected 8%, which replaces it.

1701Q is cumulative. Enter everything from 1 January to the end of Q1 — not the quarter on its own — and put what you already paid for earlier quarters in the field below. Filling it in per quarter is the most common way this return goes wrong, and the answer still looks plausible.
