The best MTD software for your small business is any product on HMRC's official recognised list that can keep digital records and file your quarterly updates and Final Declaration. HMRC checks and recognises software, but it does not endorse or recommend any single product. You choose between two valid routes: all-in-one accounting software, or spreadsheets plus bridging software with digital links.
Making Tax Digital (MTD) for Income Tax becomes mandatory from 6 April 2026 for sole traders and landlords whose qualifying income is over £50,000. About 860,000 people are in this first wave. This guide explains what makes software compatible, the capabilities you must have, and how to pick the right type for how you work, without quoting invented prices or fake feature claims.
Who needs MTD for Income Tax software in 2026?
You are in the first wave of MTD for Income Tax if your qualifying income (your gross turnover or receipts from self-employment and property, before you deduct any expenses) is over £50,000. HMRC assesses this from the figures on your 2024/25 Self Assessment return.
The threshold then steps down:
- From 6 April 2026: qualifying income over £50,000.
- From 6 April 2027: qualifying income over £30,000.
- From 6 April 2028: qualifying income of £20,000 or more.
If you are below the current threshold you can carry on with a normal Self Assessment return for now, but it is worth getting your records digital early. For the full picture of how the regime works, read our pillar guide to Making Tax Digital for Income Tax.
What makes software HMRC-recognised or compatible?
"Compatible" or "recognised" software is software that has passed HMRC's recognition process. HMRC checks that the product can keep your digital records and submit both the quarterly updates and the Final Declaration correctly. Passing that process is a technical tick, not a seal of approval: HMRC is clear that it does not endorse, rate or recommend any one product or provider over another.
That is why the single most useful thing you can do is check HMRC's own Find software that works with Making Tax Digital for Income Tax finder. It is the authoritative, current list, it is filterable, and at least one free product appears on it. Any list of "best" products elsewhere (including ours) is just commentary on top of that official source.
What are the two valid routes to filing?
There are exactly two compliant ways to meet the rules.
Route 1: all-in-one MTD-compatible software
One product does everything: it captures your income and expenses as digital records, then files your quarterly updates and Final Declaration straight to HMRC. Most cloud bookkeeping and accounting tools sit here.
Route 2: spreadsheets plus bridging software
You keep your records in a spreadsheet and use bridging software to send the figures to HMRC. The rule that catches people out is the digital link: the data must flow from spreadsheet to bridging tool digitally, with no manual re-typing or copy-pasting of totals between systems. If you like spreadsheets, this route lets you keep them. Our guide to bridging software and digital links walks through how the connection has to work.
What must MTD software actually do?
Whichever route you pick, the software has to deliver four things:
- Keep digital records of your business income and expenses, with digital links between any separate systems.
- File four quarterly updates a year. The first quarterly update ever falls due on 7 August 2026.
- Handle cumulative updates. Each quarterly update restates your year-to-date income and expenses and overwrites the previous one. They are totals only, with no accounting adjustments, so a mistake in an early quarter is simply corrected in the next.
- Submit the Final Declaration, which replaces your annual Self Assessment tax return. This is where accounting adjustments, allowances and reliefs are applied. For 2026/27 it is due by 31 January 2028.
If you want to understand how the year-end filing differs from the old return, see Final Declaration vs Self Assessment.
Which type of MTD software suits you?
Software falls into a few broad categories. The table below compares the types, not named brands, so you can match a category to how you work, then confirm specific products on the HMRC finder. It contains no prices and no invented features on purpose.
| Software type | Best suited to | Trade-offs |
|---|---|---|
| All-in-one cloud accounting software | Sole traders and small businesses who want one tool for bookkeeping, quarterly updates and the Final Declaration, and who like bank feeds and mobile apps. | Usually a monthly subscription; more features than a very simple business may need. |
| Bookkeeping or spreadsheet records plus bridging software | People who already keep good spreadsheets or use a bookkeeping tool that is not itself MTD-ready, and want to keep their existing system. | Two moving parts to maintain; you must set up and preserve a proper digital link so figures are never re-typed. |
| A free HMRC-listed option | Sole traders with simple, low-volume records who want to meet the rules at no software cost. | Fewer features and less hand-holding; check the HMRC finder for what each free product actually covers. |
| Landlord-specific tools | Landlords who want property income, tenancies and allowable expenses handled in one place. | May not suit a mixed self-employment plus property affair; confirm it files everything you need. |
If you also run a limited company or compare mainstream cloud tools, our overview of Xero vs QuickBooks vs FreeAgent gives useful context, though always verify current MTD for Income Tax recognition on the HMRC finder.
Worked example: a sole trader with £60,000 turnover
Priya is a self-employed designer with £60,000 of turnover in 2024/25. Because her qualifying income is over £50,000, she is in the first MTD for Income Tax wave from 6 April 2026 and must file four quarterly updates for 2026/27:
| Quarter | Period covered | Filing deadline |
|---|---|---|
| Q1 | 6 Apr to 5 Jul 2026 | 7 August 2026 |
| Q2 | 6 Jul to 5 Oct 2026 | 7 November 2026 |
| Q3 | 6 Oct 2026 to 5 Jan 2027 | 7 February 2027 |
| Q4 | 6 Jan to 5 Apr 2027 | 7 May 2027 |
Her Final Declaration for 2026/27 is then due by 31 January 2028, replacing the old Self Assessment return.
If Priya chooses spreadsheets plus bridging: she keeps her familiar income and expenses spreadsheet and adds a bridging tool that reads it digitally and files each update. Cheaper and comfortable if she is confident with spreadsheets, provided she never re-types figures by hand.
If Priya chooses all-in-one software: she links her business bank account, categorises transactions as they arrive, and the same tool files all four updates and the Final Declaration. More automation, at the cost of a subscription. Because updates are cumulative, if she mis-categorises something in Q1, Q2 simply restates the corrected year-to-date totals. To sanity-check where she stands, she can use our MTD Income Tax checker and estimate her bill with the self-employed tax calculator.
What are the MTD for Income Tax deadlines for 2026/27?
The standard quarterly periods and deadlines are fixed: 7 August 2026, 7 November 2026, 7 February 2027 and 7 May 2027, followed by the Final Declaration on 31 January 2028. You can make a calendar-quarter election (periods ending 30 Jun, 30 Sep, 31 Dec and 31 Mar) if that fits your bookkeeping better, but the four filing deadlines stay exactly the same. For a deeper look at the first one, see our guide to the 7 August 2026 quarterly deadline.
Are there penalties if you miss a quarterly update?
This is where accuracy matters. For the 2026/27 tax year there are no penalties for missing a quarterly update deadline: HMRC is running a first-year grace period. Penalty points for quarterly updates only start to apply for tax years after 2026/27.
When the points regime does bite, it is points-based: one point per missed submission, and at a 4-point threshold you get a £200 penalty, with a further £200 for each later late submission. Points below the threshold expire after 24 months.
Late-payment penalties are different and do apply from the year you join MTD. In your first year, there is no late-payment penalty if you pay the tax due (or agree a Time to Pay plan) within 30 days of the due date. After the first year, late-payment penalties can start after 15 days. In short: missing a 2026/27 quarterly update will not fine you, but paying your tax late still can.
Can you be exempt from MTD for Income Tax?
Yes. Some people are automatically exempt, and others can apply to HMRC for an exemption if it is not reasonable or practicable for them to use compatible software, for example because of age, disability, being digitally excluded, living somewhere with no reliable internet, or religious grounds. The key point is that you must apply to HMRC; you cannot simply decide to stop filing. If you think this is you, do not assume, get the exemption confirmed.
How to choose and sign up

Frequently asked questions
Does HMRC recommend a best MTD software?
No. HMRC recognises software that passes its process but does not endorse or recommend any single product. The authoritative list is HMRC's Find software that works with Making Tax Digital for Income Tax finder, which includes at least one free option.
Can I still use spreadsheets under MTD for Income Tax?
Yes. You can keep spreadsheets if you add bridging software that files your updates, as long as there is a digital link between them so figures are never re-typed by hand. This is one of the two valid routes HMRC accepts.
Will I be fined for missing a quarterly update in 2026/27?
No. There are no penalties for missing a quarterly update deadline in the 2026/27 tax year. Penalty points for quarterly updates apply only from tax years after 2026/27. However, late-payment penalties can still apply from the year you join MTD.
When is the first MTD for Income Tax deadline?
The first quarterly update covers 6 April to 5 July 2026 and is due on 7 August 2026. Three more follow on 7 November 2026, 7 February 2027 and 7 May 2027, with the Final Declaration due by 31 January 2028.
