# Filing and contribution deadlines in October 2027

Reviewed by [Mar Angelo N. Revelo](https://philforms.com/about/mar-angelo-revelo), founder of PhilForms.

These are the recurring deadlines from the PhilForms deadline calendar that fall in October 2027. A date that lands on a weekend or holiday is shown on the next working day, with the date the rule gives.

Each one applies only to the taxpayers or employers it names; the form page says who files, where, and what to attach.
