Never miss a UK tax deadline
Missing a filing or payment deadline means automatic penalties and interest from HMRC — even when no tax is due. This calendar brings the key UK tax dates together in one place so you can plan ahead: Self Assessment, VAT returns, PAYE and CIS, corporation tax, and Companies House filings. If you would rather never think about deadlines again, we handle them for you.
Frequently asked
What are the dates I really cannot miss?
For individuals, 31 January — the filing deadline, the balancing payment and the first payment on account all fall on it — and 31 July for the second payment on account. For companies, corporation tax nine months and a day after the year end, and the accounts filing deadline, which is a different date. For employers, every payday, because payroll has to be reported on or before it.
What happens if I file a tax return late?
A fixed penalty applies immediately at midnight, with no discretion for being a day late and regardless of whether any tax is owed. It escalates at three, six and twelve months, and interest runs on unpaid tax separately from the penalties. Filing on time with an estimated figure and correcting it later usually costs less than filing late.
Does the deadline change if I have nothing to pay?
No. The obligation to file and the obligation to pay are separate, and the penalty for late filing applies even when the return shows nothing owed. It is one of the most common and most avoidable charges we see.
Are the payment dates the same as the filing dates?
Often not, and assuming they are is a reliable way to pay interest. Company accounts and corporation tax have different deadlines from each other. VAT filing and payment usually share a date, but payment must clear rather than be initiated by it.
Never miss a date
We can carry the deadlines for you.
Filing dates do not move and HMRC does not send reminders that help. Hand the calendar to us and stop tracking it.
