Yes, you can do a self-assessment tax return yourself — and many people in the UK do it each year. If your finances are simple, it’s often quite straightforward. HMRC (HM Revenue & Customs) provides an online system that guides you through the process.
Who Needs to Do a Self-Assessment?
You usually need to do a self-assessment tax return if:
- You’re self-employed
- You earn money outside your main job (like rental income or side gigs)
- You’re a company director
- You have investment income or foreign income
If you’re unsure, HMRC’s website has a quick checker to see if you need to file.
How to Do a Self-Assessment Tax Return Yourself
Here’s how you can do it step-by-step:
- Register with HMRC – You’ll need a Unique Taxpayer Reference (UTR).
- Keep records – Save invoices, receipts, and any income or expense details.
- Log in online – Use your Government Gateway ID to access the HMRC system.
- Fill in the form – The system will ask you questions based on your situation.
- Check and submit – Review everything carefully before submitting.
- Pay what you owe – HMRC will tell you how much tax you need to pay.
Should I Get Help?
While it’s possible to do your self-assessment tax return yourself, some people choose to get help from an accountant or financial expert — especially if things get more complicated.
But if your income is simple, doing it yourself can save money and give you a better understanding of your finances.
Can I do a self-assessment tax return myself? Yes — and with the right records and a bit of time, it’s completely doable.
