You do not have to wait until January to do your 2024 to 2025 Self Assessment tax return – you can it submit now and reap the benefits of early filing.

In fact, almost 300,000 early birds filed their tax return in the first week of the tax year.

Doing it early has benefits:

  • get peace of mind and avoid the stress of doing it at the last-minute
  • you’ll know what you owe, so you can budget for the year and pay your tax bill in instalments if you need to – you can also get help if you find you can’t pay
  • you can find out sooner if you’re owed a refund – and you’ll get it sooner too
  • filing early provides proof of income which you may need for a mortgage, loan or if you want to claim benefits
