Can I do my own self assessment tax return?

Yes. You might want to complete and submit your self assessment tax return yourself, but many people find it quite boring, complicated and stressful, especially when there’s a deadline involved and a penalty for submitting it late. If you get any of the detail wrong, or it’s incomplete or unclear, HMRC might want to ask you more questions too.

That’s where we come in. Our fully qualified accountants can take away the boredom, stress and worry. They’ve had years of experience and will able to guide you through the process and make it as easy and quick as possible.

That way you can get back to running your business and private affairs: the things you really want to be doing.
