Tax deadlines for your diary
31 October 2021
This is the deadline for most paper tax returns. Even if you’re planning to complete your tax return online, it’s a good date to start getting your ducks in a row. Giving yourself more time to find or re-order any lost paperwork and claim for everything you’re entitled to can make things less stressful. You’ll also have three months to put extra cash aside to cover any shortfall.
30 December 2021
If you’re submitting an online tax return and want HMRC to collect the tax you owe from your wages or pension, you’ll need to submit your return by 30 December 2021. Your bill will need to be less than £3,000 and you’ll need to already pay tax via PAYE to be eligible.
31 January 2022
This is the deadline for completing your online tax returns and for paying the tax you owe. But, if you can help it, don’t leave it to the last minute.
If something goes wrong, it’s unlikely you’ll have time to put things right. For instance, you might not be able to log into the Government Gateway to complete your return and payment, or you could realise you’ve misplaced paperwork and need to order replacements.
There’s usually a second payment deadline of 31 July if you make advance payments towards your bill (known as ‘payments on account’). But if you’re not on this scheme, you’ll usually pay a penalty if you’re late.
