Weekends, bank holidays and a few things we left out
- Payments due on a weekend: GOV.UK says Self Assessment payments must reach HMRC on the last working day before a weekend or bank holiday deadline, unless you pay by Faster Payments or by debit or credit card. For Class 1A National Insurance the payment must arrive on the last working day of the week, unless you use Faster Payments.
- Tax-Free Childcare: you must sign in to your childcare account every 3 months to reconfirm your details or the top-ups stop. Your date depends on when you applied, so it isn't in this calendar. Your account shows when it's due; see the Tax-Free Childcare guide.
- Child Benefit charge: the 5 October dates above are also the deadline to register for Self Assessment if you need to pay the High Income Child Benefit Charge that way. If you don't need a tax return for any other reason, you can usually pay the charge through PAYE (your tax code) instead, as long as you set it up by 31 January after the tax year; see the High Income Child Benefit Charge guide.
- Not included: dates we couldn't confirm on GOV.UK today, such as the 2027-28 ISA limit, and deadlines that depend on your own circumstances, such as reporting UK property sales.
FAQ
How do I add the UK tax deadlines calendar to my phone?
On an iPhone or iPad, tap the Subscribe button on this page and confirm. On Android, use the Google Calendar button from a browser signed in to your Google account; the calendar then syncs to the Google Calendar app. You can also paste the feed address into any calendar app that supports subscribing by URL.
Will the calendar update itself?
Yes. It's a subscription, not a one-off import. The feed asks apps to check for changes once a day, and if a date changes on GOV.UK we update it. Each app decides how often it actually refreshes, and Google Calendar can take longer than a day.
When is the Self Assessment deadline for the 2025-26 tax year?
Paper returns must reach HMRC by 11:59pm on 31 October 2026. Online returns are due by 11:59pm on 31 January 2027, which is also the deadline to pay any tax you owe for 2025-26 and your first payment on account for 2026-27.
What are the Making Tax Digital for Income Tax quarterly deadlines?
Quarterly updates are due by 7 August, 7 November, 7 February and 7 May (the following tax year). The deadlines are the same for standard and calendar update periods. HMRC says it won't give penalty points for late quarterly updates in the 2026-27 tax year, but you must send them before you can submit your tax return.
What if a deadline falls on a weekend?
For Self Assessment payments, GOV.UK says that if the deadline falls on a weekend or bank holiday your payment must reach HMRC on the last working day before, unless you pay by Faster Payments or by debit or credit card. 31 January 2027 is a Sunday and 31 July 2027 is a Saturday.
Do I need an account, and do you see my calendar?
No. The calendar is a free, read-only file. Subscribing doesn't need an account with Tidy Sheets, and we can't see your calendar or anything in it.

Checked 17 October 2026. Times are UK time. If you register after 5 October, HMRC will give you a different deadline for your return (3 months from the date of its letter or email), but the tax is still due by 31 January; follow what HMRC tells you.
