Quarterly income taxFORM 1701Q

Quarterly filings are cumulative: each 1701Q recomputes the year so far and pays only the difference. That design forgives estimation errors mid year and settles everything on the annual return.

Estimate only. Creditable withholding from 2307s, prior year credits, and other adjustments belong on the actual return.

The Dates

Three quarters, three deadlines

May 15, August 15, and November 15, with the fourth quarter folding into the annual return in April. The deadline page keeps the details.

FAQ

Questions people actually search

Bakit cumulative ang 1701Q?
Each quarter reports the year so far and credits what earlier quarters already paid, so errors self correct as the year runs.
Do 8% filers deduct expenses here?
No. The 8% option taxes gross receipts above the 250,000 peso allowance; expenses never enter it.
What if my result is negative?
Nothing is due for the quarter. Overpayment positions settle on the annual return.
