GoSimpleTax – What You Need to Know

GoSimpleTax is one of the UK's most established Self Assessment software brands with over 20,000 customers in 30 countries file more than 125,000 returns annually using its HMRC-recognised platform (Trustpilot 4.4/5, 2,700+ reviews). It handles all standard Self Assessment forms including SA100, SA102, SA103, SA104, SA105, SA106, SA107, SA108, and SA109 covering sole traders, landlords, non-residents, and those with foreign income.

GoSimpleTax acquired !Coconut in 2023 and the two brands now share the same directors and company. !Coconut (getcoconut.com) is the GoSimpleTax family's HMRC-recognised MTD for Income Tax product, a simplified accounting app designed for sole traders, landlords, and CIS subcontractors. !Coconut is FCA-authorised as an Account Information Services Provider (FRN: 931194), connects to over 25 UK banks via Open Banking, and is available on iOS, Android, and web. Features include automatic bank feed imports, receipt scanning, unlimited professional invoicing, expense categorisation, real-time in-year tax estimates, profit and loss reports, and cash flow summaries.

The MTD and Self Assessment products work together: !Coconut handles quarterly digital record keeping and MTD submissions; GoSimpleTax handles the annual Self Assessment return. The !Coconut Full plan (£159.99/year) bundles both. Landlords with a Zempler business bank account can access !Coconut free for two years. !Coconut is deliberately simplified, it does not offer property portfolio management, tenant management, HMO support, joint ownership automation, a formal chart of accounts, or double-entry bookkeeping. Its philosophy is simplicity and accessibility for landlords and sole traders who find traditional accounting software overly complex.
