The situations where untied is most likely to make sense
People with mixed income (property + self-employment or PAYE), sole traders who want a phone-only workflow, and non-resident and joint-owner landlords with complex returns.
What the published plan prices look like
| Plan | Price | Notes |
|---|---|---|
| Lite | £5.42/mo | £64.99/year, VAT included; 30-day free trial; one PAYE employment; self-employment and property income each capped at £90,000; 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.
