Deadlines are statutory; if the last day is a weekend or holiday they move to the next business day.
The office builds a monthly checklist for VAT, MPHB, income, corporate, BSMV and stamp tax. Monthly SSI is not a separate 23rd — it sits inside MPHB. Hire notices are the same day; exits within 10 days.
Provisional tax is not VAT: it is an instalment of period profit and is due by the 17th of the second month after the period. For the 2026 third period that line is 17 November.
This page is the frame. Concrete September–November 2026 dates sit on the Tax calendar page. Special regimes, exemptions and credits sit on the working paper.
