What the published plan prices look like
| Plan | Price | Notes |
|---|---|---|
| Lite | £5.42/mo | £64.99/year, VAT included; 30-day free trial; paid plan required for filing; income caps apply |
| Pro including MTD | £10.83/mo | £129.99/year, VAT included; 30-day free trial; paid plan required for filing |
A note before you decide
untied is often listed as free in roundups, but the free version is a 30-day trial and filing requires a paid plan. Plans are priced per tax year with VAT included, which is unusual for this market, so compare like-for-like against ex-VAT monthly prices carefully.
