MTD for Income Tax (MTD ITSA) became mandatory on 6 April 2026 for sole traders and landlords with annual income above £50,000. In April 2027, the threshold drops to £30,000, pulling in hundreds of thousands more businesses. Quarterly returns replace the familiar annual Self Assessment — and ‘readiness’ means more than installing software. It means restructuring your record-keeping, your cashflow, and your relationship with your accountant. Most sole traders are not yet ready, even if they think they are.
Who Is Affected by MTD for Income Tax and When
MTD for Income Tax applies to sole traders and landlords above specific income thresholds — and ‘income’ here means gross income from self-employment and property, not taxable profit. A sole trader with £45,000 of turnover and £20,000 of costs has £45,000 of qualifying income for MTD purposes, not £25,000. This catches many small businesses who did not expect to be in scope. The official scope sits on the gov.uk MTD ITSA guidance.
| From Date | Threshold | Who Is In Scope |
|---|---|---|
| 6 April 2026 | £50,000+ qualifying income | Sole traders and landlords with gross self-employment and property income over £50,000 |
| 6 April 2027 | £30,000+ qualifying income | Threshold drops — hundreds of thousands more businesses in scope |
| 6 April 2028 | £20,000+ qualifying income | Third phase confirmed by HMRC — bringing an estimated additional 900,000 sole traders and landlords into MTD ITSA |
General partnerships and limited companies are not affected by MTD ITSA — companies sit under Corporation Tax MTD, which has been consulted on but not yet scheduled. If you trade through a limited company, this article does not apply to your corporate returns. It does apply to any personal property income or sole trader side income above the threshold.
What Quarterly Reporting Under MTD for Income Tax Actually Involves
Under annual Self Assessment, you file one return by 31 January covering the whole prior tax year. Under MTD ITSA, you submit five reports per tax year: four Quarterly Updates (summarising income and expenses for each three-month period), plus a Final Declaration covering adjustments, allowances, and finalising the figures.
| Period Covered | Deadline |
|---|---|
| 6 April – 5 July 2026 (Q1) | 7 August 2026 |
| 6 July – 5 October 2026 (Q2) | 7 November 2026 |
| 6 October 2026 – 5 January 2027 (Q3) | 7 February 2027 |
| 6 January – 5 April 2027 (Q4) | 7 May 2027 |
| Final Declaration for 2026/27 | 31 January 2028 |
Each Quarterly Update is a running total of income and expenses by category. It is submitted directly from MTD-compatible software to HMRC — you cannot key it into your HMRC online account manually. The Final Declaration is where reliefs, capital allowances, pension contributions, and any non-digital adjustments are applied.
What Counts as a Qualifying Digital Record
‘Digital record’ is a technical term with specific meaning under MTD rules. Each transaction must be recorded electronically with: the date, the amount, and the relevant tax category. Scanning receipts into a folder on your laptop is not enough — the data has to be structured so that software can read it. The acceptable formats are:
- Direct bank feed into MTD-compatible software (the common path)
- Manual entry into MTD-compatible software
- Digital-link import from another digital system (for example, an invoicing tool feeding accounting software)
- Spreadsheet with bridging software that submits to HMRC via API — acceptable but technically complex
The test HMRC applies: could an inspector trace every digit on your Quarterly Update back to a digital source without manual re-entry? If the answer is no, you are not MTD-compliant even if your figures are correct.
HMRC-Approved Software Options
HMRC maintains a list of recognised MTD ITSA software providers. The most widely adopted for sole traders and landlords include Xero, QuickBooks, FreeAgent, Sage Business Cloud, and Coconut. Prices range from £10 to £35 per month. HMRC also supports ‘bridging’ software — tools that connect spreadsheets to MTD submissions — which suits those with complex existing spreadsheet workflows but requires more setup.
For landlords with only a handful of properties, FreeAgent and Coconut offer the smoothest entry. For sole traders with mixed business models, Xero and QuickBooks are the mainstream defaults. The right choice depends less on features and more on which one your accountant already supports — because quarterly reporting will mean more accountant involvement, not less.
Exemptions — Who Can Apply and How
HMRC allows digital exclusion exemptions in narrowly defined cases: age or disability that prevents digital use, remoteness of location without reliable internet, religious objection to electronic communications, or a practical reason why digital recording is not reasonable. Exemptions are granted on individual application, not by category. The application is made in writing to HMRC with supporting evidence. In practice, exemption is hard to obtain for anyone under 75 living in an area with broadband access.
The Penalty Regime for Non-Compliance
MTD uses a points-based late submission penalty system, introduced in 2024 and now fully operational.
| Offence | Penalty |
|---|---|
| Missed quarterly update | 1 point; 4 points in 12 months triggers £200 penalty |
| Missed Final Declaration | Standard Self Assessment penalty (£100 fixed, then daily, then 5% surcharges) |
| Late payment 15 days | 2% of unpaid tax |
| Late payment 30 days | Further 2% of unpaid tax (total 4%) |
| Late payment 31+ days | Daily penalty at 4% per annum |
| Non-digital records | £100–£500 per submission, depending on severity |
Points reset to zero only after a clean 24-month compliance period. For a sole trader who misses one quarterly update every year, points compound and penalties become persistent.
Common Mistakes
- Assuming turnover below the threshold means exemption — if you have combined property and self-employment income and the total exceeds the threshold, you are in scope
- Running a spreadsheet and planning to enter figures into software quarterly — this fails the digital-link requirement and risks penalties
- Starting MTD in the middle of a tax year — you must have clean digital records from 6 April of your start year, not from when you bought the software
- Treating MTD as an accountant’s job — you or your team will be producing the underlying records weekly or monthly; the accountant reviews and files
- Choosing software based on price alone — the cheapest option is often the one your accountant does not support, doubling their time to handle your returns
Key Takeaways
- Check your combined self-employment and property income against the threshold for your start year (£50,000 from 2026, £30,000 from 2027)
- Move to MTD-compatible software at least three months before your start date, to build clean records from day one
- Align with your accountant’s preferred platform — it cuts both your time and their fees
- Budget for four quarterly reviews per year plus the Final Declaration, not one annual return
- Understand the points-based penalty system — persistent small misses are worse than one-off errors

Frequently Asked Questions
When does MTD for Income Tax apply to me?
If your gross self-employment and/or property income exceeds £50,000 per year, MTD ITSA applies from 6 April 2026. The threshold drops to £30,000 from 6 April 2027 and to £20,000 from 6 April 2028 — all three phases now confirmed by HMRC. The threshold is based on gross income, not taxable profit, and combines property and self-employment income. HMRC has also confirmed a soft-landing year for 2026/27: no financial penalty points for late Quarterly Updates during the first four quarters, though the full penalty regime applies from 2027/28.
Do I still need to file a Self Assessment return under MTD ITSA?
The annual Self Assessment is replaced by five MTD submissions: four Quarterly Updates plus a Final Declaration that serves the same purpose as the old annual return. The Final Declaration is due 31 January, matching the old Self Assessment deadline. Most other Self Assessment pages — employment, pensions, investments — still apply and feed into the Final Declaration.
What software do I need for MTD for Income Tax?
HMRC publishes a list of recognised MTD ITSA software. The main options for sole traders and landlords are Xero, QuickBooks, FreeAgent, Sage Business Cloud, and Coconut, priced between £10 and £35 per month. You can also use spreadsheets with bridging software. The key requirement is that transactions flow digitally from source to submission without manual re-entry.
What happens if I miss a quarterly update?
Each missed update adds one point to your account. Four points in a rolling 12-month period triggers a £200 penalty, and every subsequent missed update in the same window adds another £200. Points only reset after a clean 24-month compliance period. Chronic small misses are treated more harshly than a one-off failure, reflecting HMRC’s focus on behavioural compliance.
Can I get an exemption from MTD ITSA?
Digital exclusion exemptions are available in narrow cases — age, disability, remoteness, or religious objection — but are granted only on individual application with supporting evidence. In practice, very few exemptions are granted to working-age taxpayers with broadband access. You apply in writing to HMRC and must provide evidence of the specific barrier to digital compliance.
I have a limited company — does MTD ITSA apply?
No. MTD ITSA applies only to sole traders and landlords filing personal income tax returns. Limited companies file Corporation Tax returns, which sit under a separate regime. MTD for Corporation Tax has been consulted on but is not yet scheduled for mandation. If you trade through a company but have personal property income above the threshold, MTD ITSA applies to that property income.
