BIR Deadlines This MonthWhat is due in August 2026, for calendar year taxpayers
One evergreen page, refreshed at the start of every month. August runs the routine withholding early, then carries two quarterly income tax dates that both move: the second quarter for individuals and the second quarter for corporations. Read the movements below before you diarise either one.
| Statutory date | Falls on | File by | Form | Covers |
|---|---|---|---|---|
| Aug 10 | Monday | Aug 10 | 1601C | July withholding on compensation |
| Aug 10 | Monday | Aug 10 | 0619E | July expanded withholding remittance |
| Aug 15 | Saturday | Aug 17 | 1701Q | Second quarter income tax, individuals |
| Aug 29 | Saturday | Sep 1 | 1702Q | Second quarter income tax, corporations |

August 15, 2026 is a Saturday, so the individual 1701Q rolls forward to Monday, August 17. August 29 is also a Saturday, and the next working day, Monday August 31, is National Heroes Day, so the corporate 1702Q rolls to Tuesday, September 1. Filing on those dates is on time.
Dates falling on weekends or holidays move to the next working day, and the table above applies that rule rather than leaving it to you. Refresh log: rebuilt August 17, 2026 against the current BIR calendar. Regular holidays declared later in the year can move a date again.
What September brings
September opens with the rolled corporate 1702Q on the 1st, returns to the withholding routine on the 10th, then the third quarter starts building toward the October filings: 2550Q and 2551Q by the 25th, and 1601EQ by month end.
