Self Assessment Tax Services in Merstham & Chessington
 Do You Need Help With Your Self Assessment?

Self Assessment is exactly what it sounds like—your legal responsibility to declare your taxable income and expenses to HM Revenue & Customs (HMRC). Every individual or business required to file must meet strict deadlines: 31st October for paper returns and 31st January for online submissions. Missing these deadlines can result in penalties, interest charges, and surcharges on unpaid tax, which can quickly add up.

At Maze Accountants, we provide expert Self Assessment tax return services in Merstham & Chessington, making the process simple, accurate, and stress-free. Our team ensures your return is filed on time, fully compliant with HMRC rules, and that you claim all eligible tax reliefs to avoid overpaying. With over 22 years of experience, we’ve helped local sole traders, landlords, directors, and small business owners stay compliant and avoid costly mistakes.
