Making Tax Digital 2026 for the Self-Employed: Your Compliance Checklist

From 6 April 2026, Making Tax Digital for Income Tax applies to sole traders and landlords whose qualifying income exceeded £50,000 in the 2024/25 tax year. You must keep digital records in HMRC-recognised software and send quarterly income and expense updates to HMRC. The first update covered 6 April to 5 July 2026 and was due by 7 August 2026.

Every guide to Making Tax Digital explains the rules. Almost none tells you exactly what to do this week. This guide does. It is written for sole traders and landlords who are already in the system (or should be) and need an actionable compliance checklist: who is in scope, how to sign up, how to pick software, every 2026/27 deadline, how the new penalty points work, and the mistakes that catch people out in year one.

This is general information about HMRC requirements, not financial advice. If your tax position is complicated, consider speaking to a qualified accountant.

What Is Making Tax Digital for Income Tax?

Making Tax Digital for Income Tax, usually shortened to MTD ITSA, is HMRC’s programme to move Income Tax reporting online. Instead of gathering a full year of figures and filing one Self Assessment return by 31 January, you now keep digital records throughout the year and send HMRC a summary of your income and expenses every three months.

Three things change for you:

1. Digital record keeping becomes compulsory. Your income and expense records must be kept in HMRC-recognised compatible software, not in a paper ledger or a standalone spreadsheet.
2. You send quarterly updates. Four times a year you submit income and expense totals to HMRC through your software. These are reporting summaries, not tax payments.
3. You still file a year-end declaration. After the fourth quarterly update you submit an End of Period Statement and a Final Declaration, which replace the old SA100 return. The deadline stays at 31 January following the tax year.

Crucially, MTD ITSA changes how and when you report, not how much tax you pay. Your payment dates do not change. Income Tax is still due on 31 January and, if you make payments on account, 31 July. For more on managing those payment dates, see our guide to tax planning strategies for small business owners.

MTD for VAT has been mandatory for VAT-registered businesses since April 2022, so this is not HMRC’s first attempt at digital reporting. MTD for Income Tax is the next phase, and limited companies are not yet in scope.

Who Must Follow Making Tax Digital from April 2026?

You must use MTD for Income Tax from 6 April 2026 if you are a sole trader or a landlord (or both) and your qualifying income exceeded £50,000 in the 2024/25 tax year.

What counts as qualifying income?

Qualifying income is your gross turnover from self-employment plus your gross rental income from UK property, before any expenses are deducted. It is turnover, not profit. A landlord receiving £55,000 a year in rent is in scope even if mortgage interest and repairs leave a much smaller profit.

If you have both self-employment and property income, the two are added together. A freelancer earning £30,000 from design work and £22,000 from a rental flat has £52,000 of qualifying income and must comply from April 2026. Each business needs its own records and its own quarterly updates.

Who is not in scope yet?

• Sole traders and landlords with qualifying income of £50,000 or less in the relevant year. You can still join voluntarily.
• Limited companies, partnerships and trusts. MTD for Income Tax covers individuals only.
• People with no self-employment or property income, such as employees with only PAYE income.

The thresholds are falling

The £50,000 threshold is only the first phase. As of the 2026/27 tax year, HMRC has announced that the rules will extend to those with qualifying income over £30,000 from April 2027, and over £20,000 from April 2028. If you are close to the current threshold, plan as though you will be caught soon. Verify the current thresholds on gov.uk before you act, as policy details can change.

How to Sign Up for Making Tax Digital

Signing up is separate from choosing software, and you must do it before you can send your first quarterly update. HMRC has said it will automatically enrol people who should be using MTD but have not registered, but relying on that is a poor strategy. Here is the process:

1. Check that you are in scope. Confirm your 2024/25 qualifying income from your filed tax return. If it is over £50,000, you should be registered.
2. Choose your compatible software first. You need it to complete sign-up, because HMRC asks for details of the software you will use.
3. Sign up through your Government Gateway account. Use HMRC’s sign-up service for MTD for Income Tax. You will need your National Insurance number, your Self Assessment Unique Taxpayer Reference (UTR), and details of your business income.
4. Authorise your software. Link your software to HMRC through Government Gateway so it can submit updates on your behalf.
5. If you use an accountant or agent, authorise them. Your agent needs separate authorisation for MTD, even if they already handle your Self Assessment. Check this is in place rather than assuming it.
6. Send your first quarterly update. For 2026/27, the first quarter ran from 6 April to 5 July 2026, with a deadline of 7 August 2026. If you are signing up late, submit any missed updates as soon as possible.

If you missed the first deadline, do not panic. HMRC confirmed a soft landing for 2026/27 (see the penalty section below), but you must still submit every missed quarterly update before you can file your Final Declaration. Unfiled updates block your year-end return.

How to Choose HMRC-Approved MTD Software

You cannot comply with MTD without compatible software, so this decision matters more than most software choices. HMRC maintains a public list of recognised software on gov.uk. Any product on that list can submit quarterly updates. The differences between products are about features, not compliance.

This article does not review or rank specific products, because pricing and features change constantly and a recommendation would be out of date quickly. Instead, here is what to evaluate:

Must-have features

• MTD ITSA compatibility. Confirm on HMRC’s recognised software list that the product supports Income Tax, not just VAT. Some products only support MTD for VAT.
• Quarterly update submission. The software must be able to send all four quarterly updates plus the End of Period Statement and Final Declaration.
• Digital record keeping. The software itself must be where your records live. A spreadsheet on its own does not qualify unless it is linked to compatible software that submits to HMRC.
• Bank feeds. Automatic import of bank transactions saves hours and reduces data entry errors.

Features worth paying for

• Receipt capture. Photographing receipts with a phone app and attaching them to transactions makes expense claims far easier to evidence.
• Estimated tax position. Many products estimate your likely tax bill as you go, which removes the January surprise.
• Multi-business support. If you are both self-employed and a landlord, check the software handles both income streams and their separate quarterly updates.
• Accountant access. If you use an accountant, make sure they can log in to review your records without you exporting files.

Can you keep using a spreadsheet?

Only with a bridge. Spreadsheets on their own are not MTD-compliant. You can keep your records in a spreadsheet and use recognised bridging software to submit the quarterly updates to HMRC. This works, but it is the highest-effort option and the most error-prone. For most sole traders, purpose-built software is cheaper in time than a spreadsheet plus a bridge.

What it typically costs

Software subscriptions are a genuine business expense and tax-deductible. Entry-level MTD-compatible products aimed at sole traders typically cost a few pounds to around £30 per month at the time of writing, with prices rising for multi-business or accountant-connected plans. Treat any figure you see as a starting point and check current pricing before you commit.

Choosing software and setting up your records go hand in hand. Our guide to bookkeeping for small business walks through setting up an MTD-ready bookkeeping routine from day one.

Your MTD Quarterly Update Deadlines for 2026/27

Each quarterly update is cumulative: it restates your income and expenses for the year to date, starting from 6 April. So the Q2 update repeats the Q1 figures plus the new quarter’s figures, and so on. This means errors in an early quarter can be corrected in a later one, which is a deliberate design feature.

The default quarterly periods and deadlines for 2026/27 are:

You can elect to use calendar quarters instead (1 April to 30 June, 1 July to 30 September, and so on). The deadlines stay exactly the same; only the period boundaries shift.

Three things the deadlines do not mean:

• They are not tax payment dates. Quarterly updates carry no tax charge. You pay Income Tax as before, on 31 January and 31 July.
• They are not optional. Every mandated taxpayer must submit all four, even in a quiet quarter.
• They are not the whole job. The quarterly updates are followed by the End of Period Statement and the Final Declaration, due by 31 January 2028 for the 2026/27 year.

Worked example: a freelance consultant

Priya is a freelance marketing consultant with £62,000 of turnover. She signed up in May 2026, submitted her Q1 update in early August, and repeats the process each quarter, with every update automatically restating the year to date. After the Q4 update she reviews the full year, submits her End of Period Statement and Final Declaration, and pays her balancing payment by 31 January 2028.

The New Points-Based Penalty System Explained

MTD replaces the old automatic £100 late-filing fine with a points-based system, similar to the one HMRC already uses for VAT. The principle is simple: occasional slip-ups cost you points, not money. Persistent non-compliance costs you money.

How points work

• Each missed submission deadline earns one penalty point.
• Points accumulate per filing obligation. If you run two businesses and both updates are late for the same quarter, you still get only one point for that deadline, not two.
• Once you reach the threshold, HMRC charges a £200 penalty, and every further late submission while you remain at the threshold triggers another £200 penalty.
• Points below the threshold expire after 24 months of no further breaches.
• Once you hit the threshold, points only reset to zero after 12 consecutive months of meeting every deadline.

The thresholds

The threshold depends on how often you file:

For a mandated MTD filer, this means four missed quarterly deadlines lead to the first £200 fine. A fifth missed deadline while at the threshold leads to another £200.

The 2026/27 soft landing

HMRC has confirmed that no penalty points will be issued for late quarterly updates during the 2026/27 tax year. This grace period gives the first wave of mandated taxpayers time to adjust. It applies to quarterly updates only. It does not cover:

• The Final Declaration and End of Period Statement, which face normal Self Assessment penalties.
• Late payment of tax, which faces separate late payment penalties.
• Failure to keep digital records or use compatible software. HMRC can charge up to £3,000 per quarter for non-compliance with the core MTD requirements.

Taxpayers joining from April 2027 (the £30,000 threshold group) do not get a soft-landing year. For them the points system applies from their first year.

Concrete examples

Example 1: one genuine slip-up. Tom misses the Q2 deadline in November 2026 because of a family emergency, but files in December. In 2026/27 there is no point at all thanks to the soft landing. From 2027/28 onwards the same slip-up would earn one point, which would expire after 24 months if he meets every other deadline.

Example 2: persistent lateness. From 2027/28, Aisha misses all four quarterly updates. After the fourth missed deadline she reaches 4 points and receives a £200 penalty. She misses Q1 of the following year too, and receives another £200. To clear her points she must now meet every deadline for 12 consecutive months.

Example 3: multiple income streams. James is a sole trader and a landlord, sending two quarterly updates per deadline. He is late with both for Q3. He receives one point, not two, because points are awarded per deadline.

Example 4: the expensive oversight. Sophie submits all four quarterly updates on time but never switches on digital record keeping, continuing to keep figures on paper and typing them into a portal. The quarterly points system is not her problem. HMRC’s non-compliance penalties are, with fines of up to £3,000 per quarter possible.

First-Year Compliance Checklist: What to Do Now

Work through it in order.

Sign-up and software

• Confirm you are in scope using your 2024/25 tax return figures (gross turnover plus gross rental income, before expenses).
• Choose HMRC-recognised MTD-compatible software from the list on gov.uk.
• Sign up for MTD for Income Tax through Government Gateway.
• Connect your software to HMRC and send a test or first submission to confirm the link works.
• If you use an accountant, confirm they are authorised for MTD specifically, not just Self Assessment.

Digital records

• Move all 2026/27 income and expense records into your compatible software. Backdated paper records for the current year should be digitised.
• Set up bank feeds so transactions import automatically.
• Photograph or scan receipts and attach them to the matching transactions.
• Categorise income and expenses consistently from the start. Consistent categories make every quarterly update faster. Our bookkeeping for small business guide shows a practical monthly routine for this.

Deadlines and calendar

• Put all four 2026/27 quarterly deadlines in your calendar with reminders one week before: 7 August 2026, 7 November 2026, 7 February 2027, 7 May 2027.
• Add 31 January 2028 for your Final Declaration and balancing payment, and 31 July 2027 for your first payment on account.
• If your income is between £30,000 and £50,000, diary April 2027: that is when you are likely to join.

Quarterly update routine

• One week before each deadline, reconcile your bank feed and categorise any uncategorised transactions.
• Review the software’s year-to-date totals for anything that looks wrong, such as duplicated income or missing expenses.
• Submit the update through the software and save the submission confirmation.
• Note the software’s estimated tax figure and set money aside. A separate savings account for tax is the simplest discipline that prevents January panic.

Year-end

• After the Q4 update (due 7 May 2027), review the full year and claim every allowable expense.
• Submit the End of Period Statement and Final Declaration well before 31 January 2028. The soft landing does not protect this deadline.
• Check your payments on account position so the 31 January balancing payment holds no surprises.

Your MTD Calendar: 2026/27 Key Dates

Verify all dates against gov.uk, as HMRC occasionally adjusts administrative deadlines.

Common Mistakes That Catch the Self-Employed Out

Treating the £50,000 threshold as profit. It is gross turnover before expenses. Many landlords and high-turnover, low-margin traders assume they are below the threshold when they are actually in scope. Check your gross figures.

Signing up but never submitting. HMRC reported that a large number of people registered for MTD before the first deadline but had not submitted their first quarterly update. Registration without submission is not compliance.

Assuming the soft landing means the deadlines do not matter. No points are issued in 2026/27, but every missed update must still be submitted before your Final Declaration. Four missed updates in May 2027 means four updates to file at once, under time pressure, with a year of messy records behind them.

Confusing quarterly updates with quarterly tax payments. Some taxpayers hear “quarterly” and start setting aside panic money for a quarterly tax bill that does not exist. Updates are reporting only. Your tax payment rhythm is unchanged.

Ignoring the 2027 and 2028 thresholds. If your qualifying income is £35,000, you are not mandated in 2026/27 but you almost certainly will be from April 2027, with no soft-landing year. Voluntary early adoption is often less painful than a forced switch.

Keeping records in software but receipts in a drawer. Digital records mean the evidence trail is digital too. A photo of each receipt, attached to the transaction, takes seconds and protects your expense claims if HMRC asks questions.

Frequently Asked Questions

Do I have to use Making Tax Digital if I am self-employed with income under £50,000?

No, not yet. If your qualifying income is £50,000 or less, MTD for Income Tax is voluntary for 2026/27. But the threshold falls to £30,000 from April 2027 and £20,000 from April 2028, so check which wave catches you and consider joining early on your own terms.

What exactly counts towards the £50,000 qualifying income?

Your gross turnover from self-employment plus your gross rental income from UK property, before deducting any expenses. It is based on the income shown on your tax return for the relevant year (2024/25 for the April 2026 start).

Do I pay tax every quarter under Making Tax Digital?

No. Quarterly updates are summaries for HMRC’s records and carry no tax charge. You pay Income Tax on the existing timetable: 31 January (balancing payment plus first payment on account) and 31 July (second payment on account).

Can I still use a spreadsheet for my accounts?

Only if it is connected to HMRC-recognised bridging software that submits your quarterly updates. A standalone spreadsheet does not meet the digital records requirement. Most sole traders find dedicated software simpler and less error-prone.

What happens if I miss a quarterly update deadline in 2026/27?

Submit it as soon as you can. HMRC will not issue penalty points for late quarterly updates in the first year. But you must file every missed update before you can complete your Final Declaration, and from 2027/28 the points system applies: one point per missed deadline, £200 at four points.

How do I choose between the tax-year quarters and calendar quarters?

The default periods run 6 April to 5 July and so on; you can elect calendar quarters (1 April to 30 June). The deadlines are identical either way. Choose whichever aligns with how you already think about your year. Most people who start from scratch pick calendar quarters for simplicity.

I am both self-employed and a landlord. Do I send one update or two?

Two updates per quarter, one for each business, but they share the same deadline. If both are late, you receive one penalty point, not two, because points are awarded per deadline.

What is the difference between the quarterly update and the Final Declaration?

The quarterly updates are cumulative summaries of income and expenses sent during the year. The Final Declaration, submitted with your End of Period Statement after year end, is the formal statement of your total taxable income. It replaces the old SA100 and its deadline (31 January) carries normal Self Assessment penalties.

Do I need an accountant for Making Tax Digital?

No, it is not a legal requirement. Many sole traders manage MTD themselves with compatible software. An accountant adds value if your affairs are complex, if you want the quarterly routine handled for you, or if you want a professional review before the Final Declaration. Either way, confirm your agent is authorised for MTD.

What records do I need to keep digitally?

Your income and expense transactions, with enough detail to complete an accurate return, plus evidence such as invoices and receipts. Records must be kept in compatible software and retained for at least five years after the 31 January submission deadline of the relevant tax year. Our bookkeeping guide covers the full routine.

I am VAT-registered too. Does MTD for Income Tax change my VAT reporting?

No. MTD for VAT continues as before with its own quarterly VAT returns and its own penalty points. The two systems run side by side. If you are near the VAT threshold, our guide to the VAT registration threshold explains when registration becomes compulsory.

What if my income drops below £50,000 after I have joined?

MTD rules include provisions for leaving the system if your qualifying income falls below the threshold, but the detail depends on HMRC’s current guidance. Do not simply stop submitting updates. Check gov.uk or ask your accountant before changing your filing behaviour.

Conclusion

Making Tax Digital for Income Tax is now a fact of life for higher-earning sole traders and landlords. The rules themselves are not complicated: digital records, compatible software, four cumulative quarterly updates, and a year-end declaration. What trips people up is not the rules but the routine, which is why this guide focuses on what to do rather than just what the law says.

Start with the checklist. Confirm you are in scope, get your software connected, and put the four deadlines in your calendar today. The 2026/27 soft landing is a gift of time, not a reason to wait. Taxpayers who build the quarterly habit now will find the points-based era from 2027/28 unremarkable.

Tax rules and thresholds change, so verify the current position on gov.uk before you rely on any deadline or figure in this guide. And remember, this article is general information, not financial advice. If your tax affairs are complex, a qualified accountant is money well spent.
