Filing Deadline Calendar 2026 to 2027
Here is a free filing deadline calendar for October 2026 to June 2027. It lists payroll, sales tax and business return dates for the US, Canada, Australia and the UK on five short pages.
What is inside
- US federal payroll and information return dates, including the big Monday, Feb 1, 2027 pile up.
- Canada payroll remittance, GST/HST, T4 and personal return dates.
- Australia BAS dates with the BAS agent concession dates, plus a note on how Payday Super changed super payments.
- UK Self Assessment, PAYE and National Insurance, and VAT return dates, as HMRC states them.
The five dates that catch people out this winter
| Date | Where | What happens |
|---|---|---|
| Mon Feb 1, 2027 | US | Form 941, Form 940, W2 and 1099 NEC all land on the same Monday, because Jan 31 is a Sunday. |
| Mon Mar 1, 2027 | Canada | T4 and T4A slips are due. The last day of February is a Sunday. |
| Mon Mar 1, 2027 | Australia | The Q2 BAS moves to Monday. There is no agent concession for this quarter. |
| Thu Apr 15, 2027 | US | Individual and C corporation returns are due, plus the first estimated payment of the year. |
| Fri Apr 30, 2027 | Canada | Personal returns are due and so is any tax owing, even if you file later. |
How we checked the dates
We checked the dates on Oct 21, 2026 against the IRS employment tax due dates page, the ATO BAS due dates page and the CRA remittance page. For the US, Canada and Australia, when a date lands on a weekend we moved it to the next business day. For the UK we checked the GOV.UK Self Assessment deadlines page, the GOV.UK page on paying employers PAYE and the HMRC VAT accounting manual, and show dates as HMRC states them, including Sunday Jan 31, 2027.
This is a general guide, not tax advice. Local holidays and disaster relief can move a date, so confirm yours before you rely on it.
