Regular published prices only. Introductory offers and tax are left out. Figures are arithmetic on the provider’s own numbers, not a recommendation.
UK prices read 29 October 2026. Default: one Self Assessment return with £35,000 of self-employment income, below the 2026 Making Tax Digital threshold.
How it works
The calculator uses only figures each provider publishes. Where a fee is not published, the row says so and the figure leaves it out, which is why such a row ranks after every fully priced one. Introductory discounts are ignored because they end; tax is excluded because it depends on you.
The same code ranks the lists in our tax apps comparisons, using the defaults shown, so the order on those pages is the order this calculator gives for that profile. See how we rank.
