Honest comparison - 2026TaxMTD vs
TaxMTD vs
Sage
The UK's biggest accounting brand against a leaner, lower-cost challenger. Here is how TaxMTD and Sage compare on price, features and UK compliance - drawn from the same matrix as our full comparison.
TaxMTD vs Sage: the short version
Sage is the UK's largest accounting brand, and its cloud product - Accounting Start at around £18/month - targets everyone from sole traders to mid-sized companies, with the Sage Copilot AI assistant and a free sole-trader plan of its own. It is a mature, widely-trusted platform.
TaxMTD positions itself as the leaner, lower-cost alternative: Essential is £12/month, there is a free Starter plan for non-VAT sole traders, and AI categorisation plus Universal Credit tools are built in rather than bolted on. Both file MTD for Income Tax and VAT to HMRC, and both offer a free entry point, so the decision often comes down to price and which extras you value.
Sage brings brand weight, a long track record and Copilot. TaxMTD brings a lower monthly cost, unique UC optimisation, SA103/105/106/108 coverage, and features like inventory, budgeting and project profitability included at no extra charge where larger suites often charge more. The table below compares the two platforms feature by feature, using the same shared data as our full comparison page.
