Our verdict on MatrixTax
MatrixTax is web-based software for preparing and submitting UK Self Assessment tax returns to HMRC. It suits solo and small-business filers who want a guided form for personal and income details rather than a broader accounting platform. Coverage includes employment, self-employment, rental, foreign, investment and other untaxed income, with direct HMRC submission and application-status tracking. Multiple-language support is also available.
The plans divide the service by return complexity. Simple Tax Return covers the SA100 core return and employment income, with email support. Full Tax Return adds all supplementary pages from SA101 to SA110, plus rental, foreign and investment income, with priority support. The published starting price is 29.99, while the terms mention monthly, annual and one-off payment options. A limited trial is available before payment, and no card is required for the trial.
MatrixTax’s main strength is focused filing coverage: it can accommodate straightforward returns and several income types that require more than a basic employment return. Support is available through email, webchat and telephone, and the service provides 24/7 support. It is cloud-deployed and uses web access, with GDPR listed in its compliance details. The trade-off is a narrow ecosystem: access is web-only and no integrations are listed. Choose MatrixTax if guided HMRC submission and status visibility are the priority; consider an alternative if you need mobile access, connected software workflows or a free plan.
