Making Tax Digital for Income Tax Self Assessment (MTD ITSA) is HMRC's mandatory digital reporting system. From April 2026, if you earn over £50,000 from self-employment or property income, you must submit quarterly updates to HMRC digitally. The threshold drops to £30,000 in April 2027. Spreadsheets and annual returns are no longer compliant — you need compliant MTD ITSA software like DoneTax or DoneSE.

DoneTax is built for landlords with rental property income. DoneSE is built for sole traders with self-employment income. If you have both income types, you'll need both products — they connect seamlessly. DoneTax+ is exclusively for accountants and tax agents managing multiple clients. It receives data from DoneTax and DoneSE, never used directly by the end taxpayer.

All three DoneLabs products connect directly to HMRC's official MTD ITSA API via OAuth 2.0 — the same secure authorisation standard used by banks. You grant permission once and we handle every quarterly submission directly to the HMRC Gateway. There are no workarounds, no third-party intermediaries, and no manual form filling.

Yes. All data is encrypted at rest and in transit using AES-256-GCM — bank-grade encryption. DoneLabs Ltd is ICO registered (ICO-0001353294), UK GDPR compliant, and incorporated in the UK. Your data is never sold or shared. Our open banking integration is powered by TrueLayer, an FCA-authorised provider — read-only access only. We can see your transactions to categorise them. We cannot and will never move your money.

Under MTD ITSA you must submit four quarterly updates per tax year. The standard quarterly periods end on 5 July, 5 October, 5 January, and 5 April. Each update must be submitted within one month of the period end. DoneLabs sends you reminders well in advance and your data is always ready to submit — we don't let you miss a deadline.

Absolutely — and this is where DoneLabs shines. If your accountant uses DoneTax+, you connect via a practice code. Each quarter your data loads into their dashboard like a cartridge. They review, approve, and file. No spreadsheets emailed back and forth, no manual re-entry on their end. If your accountant doesn't use DoneTax+ yet, you can file directly yourself or ask them to get in touch with us.

HMRC operates a points-based penalty system for MTD ITSA. Each missed submission earns a penalty point, and once you reach your threshold (4 points for quarterly filers) a £200 fine is issued. Additional daily penalties can apply for extended non-compliance. DoneLabs is designed specifically to eliminate this risk — reminders, pre-populated data, and one-tap submission mean there's no excuse to miss a deadline.

Phase 1 onboarding is open now. Join the waitlist to be first through the door. We're opening access in controlled batches to ensure every submission is perfect.

Yes — under MTD ITSA you still submit an End of Period Statement (EOPS) and a Final Declaration (replacing the traditional SA return) after the tax year ends. The four quarterly updates throughout the year feed into these. DoneLabs handles all of this end-to-end — your quarterly data is already structured correctly so the final declaration requires minimal effort.

Most MTD software is legacy accounting software retrofitted for compliance. DoneLabs was built from the ground up for MTD ITSA and nothing else. Three focused products, one ecosystem — landlords, sole traders, and accountants all connected through the same engine. No bloated feature sets, no unnecessary complexity, no feature gating. One price, full compliance, direct HMRC integration.
