Making Tax Digital for Income Tax: What Self-Employed and Landlords Must Do from April 2026
Published 21 March 2026 · 10 min read · AI-assisted analysis
I used AI to break down the Making Tax Digital (MTD) for Income Tax requirements taking effect from April 2026. Here is a practical summary for self-employed professionals and landlords.
MTD for Income Tax is the biggest change to self-assessment reporting in decades. Instead of one annual tax return, affected taxpayers must keep digital records and submit quarterly updates to HMRC using compatible software. This is not optional, and penalties apply for non-compliance.
1. Who Is Affected and When
MTD for Income Tax is being rolled out in phases based on qualifying income — your gross income from self-employment and/or property before deducting expenses. If your combined qualifying income exceeds the threshold, you are in scope.
| Tax Year Starting | Qualifying Income Threshold | Who Is Affected |
|---|---|---|
| April 2026 | Above £50,000 | Self-employed individuals and landlords |
| April 2027 | Above £30,000 | Self-employed individuals and landlords |
| April 2028 (proposed) | Above £20,000 | Self-employed individuals and landlords |
This is based on gross income, not profit. A landlord with £55,000 in rental income but £20,000 in expenses still exceeds the £50,000 threshold, because qualifying income is measured before deductions. This distinction catches more people than many expect.

2. What MTD for Income Tax Actually Requires
The three core obligations under MTD for Income Tax are:
- Keep digital records using MTD-compatible software (spreadsheets alone are no longer sufficient unless they connect to HMRC via an API-enabled bridging tool).
- Submit quarterly updates to HMRC summarising your income and expenses for each quarter. These are not full tax returns — they are summary submissions of your digital records.
- Submit a final declaration by 31 January following the end of the tax year. This replaces the Self Assessment tax return and confirms your total income, reliefs, and tax liability.
Quarterly Submission Deadlines
| Quarter | Period Covered | Submission Deadline |
|---|---|---|
| Q1 | 6 April – 5 July | 7 August |
| Q2 | 6 July – 5 October | 7 November |
| Q3 | 6 October – 5 January | 7 February |
| Q4 | 6 January – 5 April | 7 May |
That means five submissions per year: four quarterly updates plus the final declaration, up from the single annual Self Assessment return most people file today.
Penalties for Late Submission
HMRC is introducing a points-based penalty system. Each late quarterly submission earns a penalty point. Once you reach 4 points (within 12 months), a £200 penalty is charged for that and every subsequent late submission until the points are reset. Points expire after 24 months of full compliance. Habitual lateness accumulates real cost quickly.
3. Cost Analysis — MTD-Compatible Software
For many sole traders and landlords who track income with a spreadsheet or paper records, compatible software is a new ongoing cost.
| Software Provider | Monthly Cost (approx.) | Annual Cost (approx.) |
|---|---|---|
| FreeAgent | £19 – £36 | £228 – £432 |
| Xero | £15 – £47 | £180 – £564 |
| QuickBooks | £12 – £35 | £144 – £420 |
| HMRC Free Software | Free | Free |
HMRC will provide free software, but it is likely limited to basic record-keeping and submission — no bank feeds, invoicing, receipt scanning, or multi-property management. For most people, a paid solution will be the practical choice.
At the mid-range, expect £200 to £400 per year in software costs that did not previously exist. For a sole trader earning £50,000, that is a 0.4%–0.8% reduction in net income — a real cost even if the government frames it as “modernisation.”
4. Real-World Scenarios
Scenario A: Freelance IT Contractor (Sole Trader) Earning £75,000
A freelance IT contractor operating as a sole trader with £75,000 gross income — comfortably above the £50,000 threshold, so MTD applies from April 2026.
Current situation:
- Files one Self Assessment return per year (usually in January)
- Tracks income and expenses in a spreadsheet
- Spends 3–4 hours once a year pulling records together
From April 2026:
- Must submit 4 quarterly updates + 1 final declaration = 5 submissions per year
- Must switch from spreadsheet to MTD-compatible software (or an API bridging tool)
- Additional software cost: roughly £250–£350/year
- Additional time: roughly 2–4 hours per quarter (8–16 hours/year, up from 3–4)
- Late penalty risk: £200 per late submission once 4 penalty points are reached
Some contractors find that proper accounting software saves time through automated bank feeds and categorisation — but the upfront adjustment period is real.
Scenario B: Landlord with 3 Properties Earning £65,000 Rental Income
A landlord with three buy-to-let properties generating £65,000 gross rental income is above the threshold from April 2026.
Key challenges:
- Must digitally record all rental income and expenses per property — repairs, management fees, insurance, ground rent, and service charges
- Quarterly submissions must consolidate income from multiple properties into a single update
- Mortgage interest is recorded as an expense but only eligible for a 20% tax credit (Section 24 restriction) — the software must handle this correctly
- Void periods, irregular income, and mixed-use adjustments add complexity
Keeping digital records in real time is a meaningful shift from gathering receipts at year-end. The quarterly rhythm forces a discipline many landlords have not previously needed, but it also gives earlier visibility into rental profitability.

5. How to Prepare Before April 2026
If your qualifying income exceeds £50,000, the clock is already ticking. Here is a practical checklist:
- Choose MTD-compatible software now. Most providers offer free trials. HMRC publishes a list of compatible software.
- Start keeping digital records immediately. Building the habit now means you will not be scrambling in August when the first quarterly update is due.
- Test with the HMRC sandbox. HMRC provides a test environment for practising submissions without affecting your real tax record — useful for verifying your software connects correctly.
- Speak to your accountant. Clarify who will handle quarterly submissions and what that means for fees. Some accountants offer MTD onboarding packages.
- Budget for the additional cost. Factor in £150–£400/year for software, plus any increase in accountancy fees for quarterly submissions.
- Review your income sources. Qualifying income is gross, not net. A small revenue increase could push you into scope even if profit remains modest.
6. A Note on Choosing the Right Software
MTD compliance means accounting software is no longer optional — it is a legal requirement if your qualifying income exceeds the threshold. Having gone through this myself as a contractor, the adjustment is real but manageable once you pick the right tool and build the habit.
Xero is one of the MTD-compatible options listed in the table above. It handles quarterly submissions directly to HMRC, automates bank feeds so categorisation becomes routine rather than a quarterly scramble, and gives your accountant shared access so they can review and submit on your behalf if that is how you prefer to work. For landlords managing multiple properties, it tracks rental income and expenses per property — which is exactly what MTD requires.
If you also deal with international income — overseas clients, rental payments in foreign currency, or supplier invoices in EUR/USD — Wise Business integrates with most accounting software and gives you the real exchange rate on every transfer, which simplifies your digital records and saves on fees.
And if you are self-employed or running a property business, protecting your ability to work is worth considering. NHS wait times for specialist referrals can be long, and when you are the business, being out of action has a direct financial impact. Vitality health insurance is one option — we both receive a £100 voucher if you sign up through this link.
These are tools we personally use or recommend. Individual circumstances vary — the right software for a sole trader with simple income will differ from a landlord with multiple properties. This is not financial advice. Always speak to a qualified accountant about your specific MTD obligations and the best setup for your situation.
