If you don’t know the tax return deadline, you must be new to the world of Self Assessment. If you’re not, then we assume you’re a natural risk-taker, playing with financial well-being fire!
Filing and paying your first tax return can feel very scary – especially if you’re worried about making mistakes, or making sure you pay the money you owe on time.
But don’t worry! As long as you prepare ahead of time and complete the tax return before the deadline, you have nothing to worry about.
Read on to find out everything you need to know about the tax return deadline.
Self Assessment is basically the way that you declare and pay your taxes to HMRC.
You’re taxed on income that you earn each tax year. This runs from 6th April – 5th April every year. You must tell HMRC about your untaxed income through a tax return, where you detail all your income and business spending.
They will then calculate any tax you owe based on your profits.
If you don’t file your tax return or pay what you owe before the deadline, you could land in a lot of trouble with HMRC. Eek! Here’s everything you need to know.

Although most tax returns tend to be filed and paid through HMRC’s online service, it’s still possible to file your tax the old-fashioned way. However, if you choose to file a paper return instead of completing it online, the deadline is different.
The deadline to file a paper return is 31st October. This is a lot earlier than the deadline for an online return, so you’ll need to make sure you’ve filled out all your forms and have posted them to HMRC (make sure you account for postage time!).
The main Self Assessment tax return form you’ll need to send is SA100, but there are other supplementary forms that you would need to fill out based on your situation. We’ve listed these forms for you here:
SA101 | SA105 |
SA102 | SA106 |
SA103 | SA107 |
SA104 | SA108 |
