    Self Assessment Help in Brentwood and Essex

    Fixed-fee Self Assessment for individuals, sole traders, landlords and directors across Brentwood, Shenfield, Billericay, Chelmsford, Romford and the wider Essex area.

    A Local Brentwood Accountant for Your Tax Return

    We're based in Brentwood and look after Self Assessment clients across Essex — from local tradespeople in Hutton and Ingatestone, to landlords in Shenfield, to directors of limited companies across Chelmsford, Billericay and Romford.

    Being local matters. We know the typical income profiles of Essex business owners, the rental market quirks around the M25 commuter belt, and we're happy to meet in person if that's easier than email and video calls.

    Who Needs to File a Self Assessment?

    You usually need to file a tax return if any of the following apply:

    • You're self-employed as a sole trader and earned more than £1,000
    • You're a partner in a business partnership
    • You're a company director taking dividends
    • You rent out property in Brentwood, Essex or anywhere else
    • You earn over £150,000 from any source

    Common Questions

    Do I need a local accountant in Brentwood to file my Self Assessment?

    No — Self Assessment is filed online with HMRC, so your accountant can be based anywhere. That said, many Brentwood and Essex clients prefer using a local firm they can meet face-to-face, drop paperwork into, and trust to understand the local business environment.

    When is the Self Assessment deadline?

    Online tax returns are due by 31 January following the end of the tax year (5 April). Paper returns must be filed by 31 October. Any tax owed is also due by 31 January, with a payment on account due 31 July.

    How much does Self Assessment cost in Brentwood?

    Fees vary depending on complexity, but for most individuals — PAYE earners with rental income, sole traders, directors, or those with side income — our Brentwood Self Assessment service starts from a fixed fee. We always quote upfront before any work begins.

    What do I need to give my accountant for Self Assessment?

    Typically your P60, any P11D, P45s, rental income and expense records, sole trader income/expenses, dividend vouchers, bank interest, pension contributions, gift aid donations, and your UTR. We'll send a clear checklist before we start.
