Making Tax Digital for Income Tax requires sole traders and landlords to keep digital records of their self-employment and property income and expenses. On top of an annual tax return, your client must update HMRC every three months using compatible software.
This guide covers what a digital record is, what you need to capture, and how to keep it current for every quarterly update.
No credit card required. Reading time: 7 minutes.
A digital record needs three things per transaction: the amount, the date, and the Self Assessment category.
Quarterly updates are cumulative – each one restates the year to date, so mistakes correct themselves in the next update.
HMRC only receives category totals. No receipts, no invoices, no adjustments, no tax calculation.
Deadlines are the 7th of August, November, February and May. Submission windows open 10 days before each period ends.
A client with both a sole trade and a rental property files eight quarterly updates a year, not four.
From 6 April 2026, MTD for Income Tax applies to sole traders and landlords with combined gross income over £50,000. This threshold drops to £30,000 from April 2027 and £20,000 from April 2028 – so more clients will be brought into scope each year, even if their income hasn't changed.
A digital record is your client’s transaction data, including date, amount, category, that is stored using software that complies with Making Tax Digital for Income Tax. Paper records do not meet HMRC's requirements once a taxpayer is mandated by MTD IT.
For each transaction, you must record three pieces of information:
The amount received or incurred
The date on which it was received or incurred
The category – using the same income and expense categories as Self-Assessment
Pro Tip: Paper records don't count once your client is mandated. A shoebox of receipts can still support the numbers, but the record HMRC requires has to live in compatible software.
MTD for Income Tax covers self-employment and UK property business income and expenses. HMRC never sees individual receipts or invoices – only the category totals in each quarterly update.
Digital records must cover:
The amount received or incurred
The date on which it was received or incurred
Digital records must cover:
The amount received or incurred
The date on which it was received or incurred
Several properties still make one business. If your client has more than one UK property, all of them are treated as a single UK property business. Your software adds the records together into one quarterly update.
Acting for a client as their accountant or bookkeeper, you must use software recognised by HMRC for Making Tax Digital for Income Tax. HMRC doesn't provide its own software, but there's a range of free and paid options. They fall into four groups.
Handle record-keeping, quarterly updates and finalisation in one place.
Where Dext Solo sits
Do the record-keeping and quarterly updates, and hand off to your existing finalisation software.
Business bank accounts that also file the quarterly update for you.
Connects existing spreadsheet records to HMRC.
If you or your client uses more than one software product, you must digitally link them. Figures cannot be rekeyed – you can't manually re-enter data between products.
What HMRC encourages
As close to real time as possible
Little and often keeps data clean and turns the quarterly update into a review rather than a rebuild.
The actual requirement
Before the update is submitted
The minimum is that digital records are entered into your software before the quarterly update for that period is submitted.
By default, update periods follow the tax year. If your client's record-keeping period ends on 31 March rather than 5 April, you can choose calendar update periods instead. Switch between the two to see how the year plays out.
Update period | Submission deadline |
|---|---|
6 April to 5 July | 7 August |
6 April to 5 October | 7 November |
6 April to 5 January | 7 February |
6 April to 5 April | 7 May |
Each update covers income and expenses from the start of the tax year to the end of that update period, not just the most recent three months. You and your client’s chosen software calculates these cumulative totals for you.
Update period | Submission deadline |
|---|---|
1 April to 30 June | 7 August |
1 April to 30 September | 7 November |
1 April to 31 December | 7 February |
1 April to 31 March | 7 May |
If your recording-keeping period ends on 31 March rather than 5 April, you can choose calendar update periods.
You must select calendar update periods for your client in your software before you send your first quarterly update. You cannot change this setting after your first update has been submitted for that tax year.
If you spot a mistake after submitting a quarterly update, you or your client do not need to resend the original update. Because each update covers the full period from the start of the tax year, corrections are automatically included in the next quarterly update.
Quarterly updates are deliberately light. Only category totals are submitted.
Nothing document-level is sent to HMRC.
Adjustments belong at finalisation, not in the quarterly update.
Your client doesn't need to work out any tax before sending an update.

If your client doesn't submit their quarterly update by the relevant deadline, they may receive a late submission penalty point. A £200 penalty is applied once the penalty point threshold is reached.
FILLING PATTERN | POINTS THRESHOLD | PENALTY AT THRESHOLD |
|---|---|---|
Standard quarterly filers | 4 penalty points | £200 |
There's a soft landing for 2026 to 2027. HMRC has confirmed that penalty points will not be applied for late quarterly updates for taxpayers entering MTD for IT in the 2026 to 2027 tax year. Points for a late tax return still apply.
Pro tip: All four updates must be in before finalisation. You cannot submit your client's Final Declaration until every quarterly update for the year has been submitted.
Dext Solo is HMRC-recognised MTD for Income Tax software. It collects and categorises client data, then submits quarterly updates directly to HMRC – working alongside your firm's existing tax software rather than replacing it.
Built for sole traders and landlords, not scaled down from full accounting software
Automation for CIS, disallowable expenses and rental income
Works with your finalisation software, or on its own
While Apron focuses on basic invoice capture and low-cost payments, Dext is built for firms that want reliable automation and scalability. With 99.9% accurate data extraction, deeper integrations, and end-to-end automation—from capture to compliance—Dext delivers efficiency and trust at scale, powering over 700K businesses and 12K bookkeeping firms worldwide.
While Apron’s data capture accuracy is not officially disclosed, Dext’s AI-driven data extraction achieves 99.9% accuracy, drastically reducing manual intervention. Combined with smart rules, duplicate detection, and auto-publishing, firms save hours per week and eliminate costly errors.
While Apron may look cheaper upfront, its lower automation and accuracy lead to manual rework, lost capacity, and potential data errors. Dext creates billable capacity through automation—letting firms handle more clients with the same team and increasing profitability over time.
Yes. Dext captures 13+ document types—from receipts and invoices to supplier statements and mileage claims—while Apron mainly handles invoices and receipts. Dext also connects with Xero, QuickBooks, Sage, FreeAgent, and 11,500+ banks and e-commerce platforms, compared to Apron’s limited integrations.
Dext’s robust duplicate detection, audit trail, and data accuracy help prevent double payments, misposted transactions, and VAT errors reducing risk exposure for firms handling large volumes of transactions.
Dext Solo handles the hard part – getting accurate data in, fast and at scale – so quarterly updates become a review rather than a scramble.
