There’s an additional payment deadline of 31st July if you make advance payments towards your bill (known as ‘payments on account’).
You’ll usually pay a penalty if your return is filed late or the payment is made late. You can appeal against a penalty if you have a reasonable excuse.
When the deadline is different
Submit your online return by 30th December if you want HMRC to automatically collect tax you owe from your wages and pension. You must be eligible.
HMRC must receive a paper tax return by 31 January if you’re a trustee of a registered pension scheme or a non-resident company. You can’t send a return online.
