Our verdict on GoSimpleTax
GoSimpleTax is cloud-based software for preparing and submitting UK Self Assessment returns to HMRC. It is designed for individuals, freelancers, sole traders, landlords, company directors, non-residents and taxpayers with multiple income types. The service covers income and expenses, tax calculations, tax-saving prompts, HMRC forms, receipt handling, error checks and plain-English guidance. Direct submission makes it particularly suitable for people who want to complete and file their return in one web-based service.
Its strongest area is tax-return depth. Individual plans cover self-employment, property forms, capital gains and tax-saving suggestions, while Residency plans add form SA109 and support for property and self-employment. Partnership plans cover the SA800 partnership return alongside property, foreign and investment income forms. Real-time calculations, tax-owed estimates, allowance prompts and checks for missing or inconsistent details add useful review support. A free account allows preparation and calculation before payment is required for submission or additional features; paid features start at 69.99, and the pricing structure includes subscription and non-subscription options.
GoSimpleTax also fits workflows built around supported accounting platforms, with integrations for FreeAgent, FreshBooks, SumUp and Xero. Email and online support are available, and the service provides guidance while users complete relevant HMRC forms. The main platform trade-off is that access is web-only, so it is less suited to buyers seeking a native mobile app. It is a strong choice for UK taxpayers with self-employment, rental, investment, residency or partnership requirements, while people with only a very simple return may prefer a narrower tool.
