Built for the one-person consultancy, the landlord with two flats, the tradesperson newly pulled into the April 2026 mandate. Dragonfin keeps your books in order year-round for free, and files them to HMRC when you're ready — for a flat annual price, not the enterprise markup the rest of the market runs on.
Free forever, on your device. No card at signup, no subscription trap.
Log income and expenses as they happen. Categorised against HMRC's structure so you always know where you stand.
When it's time to file, pick your tier and go direct to HMRC. Signed receipt for every submission.
The app is free. These are the annual prices for the submission service — pick the level of help that fits.
Prices shown are current at time of publication and may change. See our Terms of Service for the full policy.
MTD Income Tax applies to sole traders and landlords whose annual income from self-employment or property crosses these thresholds:
| April 2026 | Mandatory over £50,000 |
| April 2027 | Threshold drops to £30,000 |
| April 2028 | Threshold drops to £20,000 |
Around 1.6 million UK taxpayers will be in scope by 2028. HMRC's free filing service closed in March 2026 — anyone in scope now needs approved software.
Install the app, connect your accounts, file your first return in under ten minutes.
