Self Assessment Accountants in Southend
Leave the tax stress behind, our dedicated chartered accountants take care of your Self Assessment from start to finish.


What is a Self Assessment & Who Needs It?
Self Assessment is the process by which individuals report their income to HMRC and pay any tax owed when it isn’t automatically deducted — typically through PAYE. If you earn money outside of traditional employment, chances are you’ll need to file a Self Assessment tax return each year.
You might be self-employed as a sole trader, a director of a limited company drawing dividends, a landlord earning rental income, or a high earner with income from multiple sources. Freelancers, contractors, partners in a business, and individuals with untaxed savings or investment income — including crypto or overseas assets — may also fall under the Self Assessment system.
At ARB Accountants, we understand that tax returns can be confusing, time-consuming, and easy to get wrong — especially when your income isn’t straightforward. That’s why we offer end-to-end Self Assessment services that take the hassle off your plate. We help you understand what needs declaring, claim every allowance you’re entitled to, and stay fully compliant with HMRC regulations.
