HMRC-registered self-assessment specialists serving Harrow's professionals, family businesses, self-employed, contractors and landlords across HA1 to HA3. Full SA100 returns, payments on account, expense maximisation and HMRC compliance, from a fixed monthly fee.
Self-Assessment Accountant in Harrow
Harrow is one of North West London's most established and entrepreneurial communities, home to a large and successful Indian, Sri Lankan and wider South Asian population, a strong professional base, and a busy high-street and small-business economy. That gives the HA1 to HA3 area a varied self-assessment market: self-employed professionals and consultants, family-run retail, wholesale and food businesses, contractors working through their own companies, and a substantial London landlord base. Many households run a business or hold rental property alongside PAYE work. As a Stanmore-based firm, Harrow is right on our doorstep and we know it inside out.
Your Tax Help Accountants, HMRC-registered, handles complete self-assessment for Harrow taxpayers. SA100 returns for the self-employed and family businesses, dividends and the salary-dividend split for contractors, landlord property pages, payments on account, MTD readiness and HMRC correspondence, all at a fixed monthly fee with same-day filing available near the deadline. Whatever your mix of income, we make your return accurate and keep your bill to what it should be.
💡 As an HMRC-registered agent, we deal with HMRC directly on your behalf. Authorisation in place, returns filed, refunds chased, compliance letters handled. You only ever hear from us, never from HMRC.

📅 Get Your Free Self-Assessment ReviewReal Client Story
Client H is a Harrow professional with a PAYE salary who had built up two buy-to-let properties, with around £31,000 of rental income. He had been declaring the rent but claiming almost nothing and applying the old mortgage-interest rules, paying more tax than he needed to alongside his salary.
We prepared proper property pages, applied the 20 per cent finance-cost tax credit on his mortgage interest correctly, and claimed the costs he had missed: letting and management fees, repairs and maintenance, landlord insurance, ground rent and service charges, safety certificates and mileage to the properties. We combined this cleanly with his PAYE income.
His rental tax fell once the genuine costs and the interest credit were in, a refund came back on an amended year, and his record-keeping was set up cleanly for Making Tax Digital for landlords. He now files once a year for a fixed fee with the portfolio handled correctly.
