Four ways to get it done
There are four sensible ways to get a tax return done. Pick the one that fits how simple your affairs are and how confident you feel.
You do it all
You keep the records and file on GOV.UK. Suits one simple income, like a small side gig or one rental, with tidy records. Cost: free.
You do it, someone checks
You prepare the records and the return; a professional reviews it before you send it. Suits people who are nearly there but want peace of mind.
You keep the books, with help when needed
You do the day-to-day records and buy occasional help, for example a set-up session or a quarterly check. Suits growing businesses heading into Making Tax Digital.
A professional does it
You hand over records and a professional does the agreed bookkeeping and filing. Suits complex affairs, messy records, or not enough time.
Get qualified help if any of these apply: records are missing or don't add up; you've sold property, shares or a business; you have income from abroad; you've had a letter from HMRC you don't understand; you've missed returns for earlier years; or you're unsure whether you're self-employed at all.
