The mandate
Quarterly.
Digital.
Mandatory.
From April 2026

If you earn over £50,000 from property or self-employment income, spreadsheets and annual Self Assessment returns are no longer compliant. HMRC requires you to submit quarterly updates digitally using recognised Making Tax Digital for Income Tax software. MTD ITSA is not optional - it is the law.

From April 2027

The threshold drops to £30,000. More landlords and sole traders in scope. Same quarterly requirement. The same penalty system applies from day one.

Penalty system

HMRC operates a points-based system. Each missed submission earns a penalty point. Four points triggers a £200 fine. Daily penalties follow for extended non-compliance.

005 — FAQ
Every question.
Answered.

Everything you need to know about MTD ITSA, DoneLabs products, and how it all works. If we've missed something, email us.

01 What is MTD ITSA and does it affect me?
Making Tax Digital for Income Tax Self Assessment (MTD ITSA) is HMRC's mandatory digital reporting system. From April 2026, the mandate is live. 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.
02 Which DoneLabs product is right for me?
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.
03 How does the HMRC connection actually work?
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.
04 Is my financial data safe?
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.
05 What are the quarterly submission deadlines?
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.
06 Can I use DoneLabs alongside my accountant?
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.
07 What happens if I miss a quarterly submission?
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 is no excuse to miss a deadline.
08 When will DoneLabs products be available?
All three products are built, tested, and proven end-to-end with HMRC. Approval is the final step - not a blocker, a formality. When it lands, the waitlist goes first. No false timelines. One email when we launch.
09 Do I still need to file a Self Assessment return?
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.
10 How is DoneLabs different from other MTD software?
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.
11 What is the best MTD ITSA software for landlords?
DoneTax is built specifically for UK landlords with residential property income. It connects directly to your bank via TrueLayer open banking, automatically imports transactions, lets you categorise property expenses in seconds, and submits quarterly to HMRC in one tap. No accountant required - though if you have one, DoneTax connects directly to DoneTax+ so your data flows to them every quarter without any manual effort. At £4.99 per month it is the most focused, affordable MTD ITSA solution for landlords in the UK.
12 Do I need MTD ITSA software if I already use an accountant?
Yes - under MTD ITSA, compliant software is required regardless of whether you use an accountant. The difference is who does the filing. If your accountant uses DoneTax+, you use DoneTax or DoneSE to track your income and expenses throughout the quarter, and your data flows automatically to your accountant each quarter. They review, approve, and file on your behalf direct to HMRC via the agent API. If your accountant does not yet use DoneTax+, you can file directly yourself using DoneTax or DoneSE - it takes one tap.
