Self Assessment
No stress. No slips. No last-minute scrambles.
Self Assessment shouldn’t be a source of panic. Whether you’re a sole trader, company director, landlord, or freelancer, we make tax returns simple – and get them done right, first time.
At AD Accountancy, we don’t just tick boxes. We spot problems before HMRC does, give you clear answers, and make sure you’re not overpaying tax you don’t owe.
Who needs to file a Self Assessment?
If you’re earning untaxed income or running your own business, you probably do. That includes:
-
Sole traders and freelancers
-
Directors receiving dividends
-
Landlords with rental income
-
Investors with capital gains
-
Side-hustlers, influencers, content creators
-
Anyone with multiple income streams

We file early. Always. The sooner it’s done, the more options you have.
