The BIR tax calendar — what to file and when

Most penalties Philippine companies pay aren't for owing too much tax — they're for filing late. The Bureau of Internal Revenue (BIR) runs on a rhythm of monthly, quarterly, and annual deadlines, and once you know the shape of it, staying compliant is mostly about not missing dates. Here's the calendar at a glance.

The monthly filings

Each month, most companies deal with withholding taxes — amounts you withhold from employee salaries and from certain payments to suppliers, then remit to the BIR. These returns keep the year's withholding current so there are no surprises at year-end.

Tip

Withholding is money you've already taken out on the BIR's behalf. Remitting it late is one of the easiest penalties to avoid — and one of the most common to incur.

The quarterly filings

Every quarter, companies file income tax returns based on the period's results, and — if VAT-registered — value-added tax returns. These are interim filings: they keep your liability current through the year rather than settling everything at the end.

The annual filings

After the year closes, the big-ticket items come due:

FilingWhat it is
Annual income tax returnThe year's final income tax computation
Audited financial statementsIndependently audited accounts (above set thresholds)
AlphalistsYear-end summaries of withholding by employee and payee

For calendar-year taxpayers, the annual income tax return and audited financial statements are generally due by April 15 of the following year.

Key takeaways

  • Withholding returns are monthly — remit on time, every time.
  • Income tax and VAT are filed quarterly through the year.
  • Year-end brings the annual income tax return, audited financial statements, and alphalists.
  • For calendar-year filers, April 15 is the date to plan around.
