Making Tax Digital for Income Tax Self Assessment — known as MTD ITSA — finally goes live for the first wave of taxpayers on 6 April 2026. After several deferrals, the first phase will be mandatory for sole traders and landlords whose gross self-employment plus property income exceeded £50,000 in 2024/25.

MTD ITSA goes live 6 April 2026 for sole traders and landlords with combined gross self-employment and property income above £50,000 in 2024/25. You’ll need HMRC-recognised software to keep digital records, send quarterly updates to HMRC, and submit a Final Declaration replacing the old Self Assessment return. Threshold drops to £30,000 in April 2027 and £20,000 in April 2028.

If you fall inside the threshold, the change is significant. The familiar annual Self Assessment return will be replaced by quarterly digital updates, mandatory digital record-keeping, and a Final Declaration after the tax year end — all submitted through HMRC-recognised software. This guide explains exactly who must comply, what the new obligations look like in practice, and the steps to take before the April 2026 deadline.
⚠️ Three Phased Deadlines to Plan For
- 6 April 2026: Mandatory for sole traders and landlords with gross income above £50,000 in 2024/25
- 6 April 2027: Threshold drops to £30,000, bringing in roughly 1 million more taxpayers
- 6 April 2028: Threshold drops again to £20,000 — the largest expansion of the regime
Who Is in Scope from April 2026?
The first wave covers individual sole traders and landlords. You are inside MTD ITSA from 6 April 2026 if your gross income from self-employment plus property combined was above £50,000 in the 2024/25 tax year. Two important details often get missed:
🔍 The £50,000 Test — Common Misunderstandings
- It’s gross income, not profit. A landlord with £55,000 in rental income but only £18,000 net profit after mortgage interest and expenses is still inside MTD ITSA — gross income is what counts.
- Self-employment and property are combined. A consultant with £35,000 in fees and a buy-to-let producing £20,000 in rent has £55,000 gross — over the threshold.
- The reference year is 2024/25. HMRC looks at the figures on your 2024/25 Self Assessment return, filed by January 2026, to determine whether you must comply from April 2026.
- Limited companies are not included. MTD ITSA applies only to individuals reporting self-employment or property income on Self Assessment. Companies remain outside the regime — they file CT600s as before.
- Partnerships are deferred. General partnerships have been pushed back beyond 2026/27 — HMRC has not yet confirmed a start date.
If your 2024/25 gross income from self-employment and property is below £50,000, you remain on the existing Self Assessment regime for now — but the threshold drops to £30,000 in April 2027 and £20,000 in April 2028, so most working-age UK taxpayers with side income will eventually be drawn in.
The Three New Obligations
MTD ITSA creates three distinct compliance duties that replace the single annual Self Assessment return:
1. Digital Record-Keeping
From the start of the first MTD-mandated tax year, you must keep a digital record of every income and expense item — per business and per property income source separately. A handwritten cash book, an Excel spreadsheet on its own, or a shoebox of receipts no longer satisfies the rules. Records must be captured in functional compatible software — either a recognised accounting platform or a spreadsheet linked to HMRC-approved bridging software.
2. Quarterly Updates
Each quarter, you submit a digital update to HMRC summarising income and expenses for that period. Updates are cumulative, so each one effectively restates the year-to-date totals. The standard quarterly periods (and submission deadlines) are:
| 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 |
Many taxpayers will instead elect calendar quarter reporting (1 April – 30 June, 1 July – 30 September, etc.) which aligns more naturally with most accounting software and bank statements. This election can be made through your software at the start of each tax year.
3. Final Declaration
After the tax year ends, you replace the old Self Assessment return with a Final Declaration, due by 31 January following the end of the tax year. This is where you make any year-end adjustments — capital allowances, accounting period adjustments, claims for reliefs, and any non-MTD income (interest, dividends, employment income). For 2026/27, the Final Declaration is due 31 January 2028.
What Software Do You Need?
HMRC publishes a list of recognised MTD ITSA software. The major UK accounting platforms have all built MTD ITSA modules — including Xero, QuickBooks, FreeAgent, Sage, and FreshBooks — and most charge between £10 and £30 per month for plans that include MTD ITSA submissions.
If you use a spreadsheet for record-keeping (still permitted), you also need bridging software to digitally connect the spreadsheet to HMRC’s API. Several low-cost bridging tools exist (typically £40–£100 per year), but the workflow is materially clunkier than a full accounting platform.
💻 Software Options at a Glance
- Xero — strong all-rounder, popular with bookkeepers, MTD ITSA module included on Standard plan and above
- FreeAgent — free for NatWest and Mettle business banking customers; designed for sole traders and landlords
- QuickBooks Self-Employed — entry-level option, automated mileage tracking, lower price point
- Sage Accounting — established UK option with MTD ITSA support
- Spreadsheet + bridging software — possible but requires more discipline; recognised options listed on gov.uk
For landlords, FreeAgent and Hammock are commonly recommended — both are property-aware. For consultants and freelancers, Xero or FreeAgent typically work well. Whichever route you choose, it pays to start using it now — not after April 2026 — to be fully familiar by the time live submissions begin.

The New Penalty Regime
MTD ITSA brings UK income tax under the points-based penalty system already in place for VAT. Each missed quarterly update or Final Declaration deadline earns one point. Once a taxpayer accumulates four points (for quarterly filers), HMRC issues a £200 fixed penalty, and a further £200 penalty for each subsequent missed deadline until the points are reset.
⚠️ How the Points System Works
- Quarterly filers: 4 points = £200 penalty. Points expire after 24 months of full compliance.
- Late payment penalties sit alongside late filing penalties: 3% of unpaid tax after 15 days, 3% more at 30 days, then 10% per annum thereafter.
- Daily interest accrues on unpaid tax from the day after the deadline at HMRC’s official rate (Bank of England base rate + 4% from April 2025).
The points system is more forgiving than the old fixed penalty regime for occasional one-off slips, but materially harsher for taxpayers who consistently miss deadlines. Late payment remains expensive regardless.
Voluntary Sign-Up and the Opt-Out
Taxpayers below the £50,000 threshold can voluntarily opt in to MTD ITSA from April 2026 — useful for those who want to get ahead of the regime change before it becomes mandatory in 2027 or 2028. HMRC has run a voluntary pilot since April 2024.
There is no opt-out for those above the threshold. If you are in scope, you must comply — there is no equivalent to the VAT exemption thresholds. The only ways out are: (a) reducing gross income below the threshold for two consecutive years, (b) ceasing the relevant trade or property activity, or (c) very limited HMRC exemptions for digitally excluded individuals (proven inability to use digital tools — a high bar to meet).
What to Do Before April 2026
📋 Six-Step Pre-MTD ITSA Checklist
- 1. Confirm whether you are in scope. Check your 2024/25 gross self-employment and property income. If combined gross is over £50,000, you are in from 6 April 2026.
- 2. Choose your software now. Don’t wait until March 2026. Pick a platform, sign up, and use it for at least one full quarter before live submissions begin so you are familiar with the workflow.
- 3. Open a separate business bank account (if you don’t already have one). It dramatically simplifies digital record-keeping. Many platforms offer free banking specifically because the bank-to-software feed reduces friction.
- 4. Connect your bank feed. Live bank feeds populate income and expenses automatically — saving hours of manual entry every quarter.
- 5. Categorise your transactions monthly. Don’t let it pile up to the quarterly deadline. Ten minutes a week is far less painful than a frantic afternoon every three months.
- 6. Authorise your accountant. If you use one, ensure they are listed as your MTD ITSA agent in HMRC’s Agent Services Account before the first submission deadline.
The Practical Impact: What Will Change in Your Life
MTD ITSA is not just a software change — it changes the rhythm of tax compliance. Three things look genuinely different:
Tax thinking becomes quarterly, not annual. Where most sole traders and landlords previously thought about tax once a year (typically in panic, in January), MTD forces a four-times-a-year discipline. Most clients tell us, after a few quarters, that this is actually easier — the tax bill is no longer a January surprise, and quarterly visibility makes financial planning meaningfully better.
Accountancy fees often shift higher. Even where the work is broadly the same in volume, the fee model changes. Many firms now quote MTD ITSA on a monthly retainer (£40–£150 per month is typical for landlords and small sole traders) rather than an annual fixed fee. Expect to discuss pricing with your accountant before April 2026.
Software literacy becomes a baseline requirement. Some taxpayers — particularly older landlords who have run their portfolio on paper for decades — will need help adapting. The “digitally excluded” exemption exists but is narrow. For most, the answer is to pair good software with a good bookkeeper or accountant.
Specific Issues for Landlords
Landlords face a few quirks worth highlighting:
- Each property is one income source. If you own properties in your own name, all UK property income is treated as a single property business — one MTD ITSA stream. Furnished Holiday Lettings (formerly a separate regime) was abolished from April 2025, so most rental property is now consolidated under standard property income rules.
- Section 24 calculations still apply. Mortgage interest still falls under the basic-rate restriction for residential lettings. The quarterly updates capture gross rental income and allowable expenses; the mortgage interest credit is calculated at the Final Declaration stage. Use our Section 24 calculator to model the impact.
- Joint properties need two submissions. If you own a property jointly with a spouse or business partner, each owner files their own quarterly updates for their share of the income — creating two compliance streams from one property.
- Property held in a limited company is outside MTD ITSA. Limited company landlords continue with annual CT600s and statutory accounts. Many landlords approaching the £50,000 MTD threshold are now actively considering incorporation as part of a wider tax strategy.
Specific Issues for the Self-Employed
For sole traders, three areas often cause problems:
- Cash basis vs accruals basis. Most sole traders use the cash basis (income recognised when received, expenses when paid). This is the default from April 2024 and aligns naturally with MTD’s quarterly bank feed approach. Accruals basis is still available but optional and adds complexity.
- Capital allowances and asset purchases. Equipment purchases need correct capitalisation in your software — they are not simple expenses for tax purposes. Most software handles this correctly if categorised properly, but get the chart of accounts right at the start.
- Mixed personal-business expenses. Use of home as office, mileage, mobile phone — all need consistent monthly apportionment, not one-off year-end estimates. Software handles this if you set up rules for it once.

Frequently Asked Questions
Who has to comply with MTD ITSA from April 2026?
Sole traders and landlords whose gross income from self-employment and property combined exceeds £50,000 in the 2024/25 tax year must comply with MTD for Income Tax from 6 April 2026. The threshold is gross income (turnover plus rental income) before expenses, not profit. The threshold drops to £30,000 in April 2027 and £20,000 in April 2028.
What do I actually have to do for MTD ITSA?
Three things. First, keep digital records of your business and rental income and expenses using HMRC-compatible software. Second, send quarterly updates to HMRC summarising income and expenses for each three-month period. Third, submit a Final Declaration after the tax year end replacing the traditional Self Assessment return. The Self Assessment return goes away once you are inside MTD.
Is MTD ITSA the same as MTD VAT?
No. MTD VAT applies to VAT-registered businesses and has been mandatory since 2019. MTD ITSA is a separate regime covering Income Tax for sole traders and landlords. The principles are similar (digital records, regular submissions through compatible software) but the rules, deadlines and software requirements are distinct.
What software do I need for MTD ITSA?
You need software that HMRC has approved as MTD ITSA-compatible. Major accounting platforms including Xero, QuickBooks, FreeAgent, Sage and FreshBooks have MTD ITSA modules. Spreadsheets can also be used if combined with HMRC-recognised bridging software. Bookkeeping notebooks and basic spreadsheets alone are no longer sufficient.
What are the penalties for MTD ITSA non-compliance?
From April 2026, MTD ITSA submissions move to the points-based penalty regime. Each missed quarterly update or final declaration deadline earns one penalty point. Once a taxpayer accumulates four points (for quarterly filers), a £200 fixed penalty applies, with further £200 penalties for each subsequent missed deadline until the points are reset by 12 months of full compliance.
