You'll need to file a Self Assessment tax return if you're self-employed, a company director receiving dividends, a landlord with rental income, or if you have other untaxed income such as savings interest above your allowance, capital gains, or foreign income.
As accountants in Brentwood, we prepare and file tax returns for individuals across Essex. We make sure every allowance and relief is claimed, and that your return is filed accurately and on time.
