Your new tax calendar: what MTD for income tax looks like on the ground
Making Tax Digital for Income Tax is no longer something coming down the line — it went live on 6 April 2026. If your combined income from self-employment and property hit £50,000 or more in the 2024–25 tax year, you are already in scope. That means one annual Self Assessment return has been replaced by four quarterly digital updates plus a year-end final declaration. Miss enough of those deadlines, and HMRC’s points-based penalty system starts building up — at four points, a £200 fine kicks in, and then another £200 for every miss after that.
This post is not a policy explainer. It is a practical walkthrough of what your tax year now looks like — the actual dates, the actual workload, and the straightforward steps that keep you on the right side of it without it taking over your life.
Who is in scope right now
The threshold is based on your gross income — turnover, not profit. So if you turned over £50,000 before expenses, you are in.
<INCOME_THRESHOLD_TABLE>
| Phase | Who joins | Based on income from |
|---|---|---|
| Phase 1 — from 6 April 2026 | Sole traders and landlords with qualifying income over £50,000 | 2024–25 tax return |
| Phase 2 — from 6 April 2027 | Qualifying income over £30,000 | 2025–26 tax return |
| Phase 3 — from 6 April 2028 | Qualifying income over £20,000 | 2026–27 tax return |
One thing that trips a lot of people up: qualifying income is your gross income from self-employment and UK property before expenses are deducted. If you have multiple income sources, these are added together — so someone earning £32,000 from self-employment and £20,000 from rental property would have qualifying income of £52,000 and falls within MTD from April 2026.
And it is worth noting that other sources of income are ignored for this test — you do not include wages from employment (PAYE), dividends from shares, or interest on savings.
Limited companies are currently exempt from these specific rules, and there is no Making Tax Digital for corporation tax mandate for 2026. If you trade through a limited company, this does not affect you yet.
The scale of this change
This is not a niche rule change. HMRC statistics reveal that 864,000 sole traders and landlords are expected to be in the first wave of taxpayers being brought into the Making Tax Digital for Income Tax regime from April 2026. HMRC estimates around 4.2 million self-employed individuals and landlords will eventually fall within scope.
If you are a sole trader electrician, plumber, builder, or any other trade turning over a decent amount, there is a good chance this applies to you now — or will do within the next two years.
Your four quarterly deadlines
This is the big practical shift. Making Tax Digital for Income Tax is one of the biggest changes to UK self-assessment in decades, replacing the familiar annual tax return with a system of four quarterly updates each year, plus a final end-of-year declaration.
Here are the dates for the 2026–27 tax year:
| Quarter | Period covered | Deadline |
|---|---|---|
| Q1 | 6 April – 5 July 2026 | 7 August 2026 |
| Q2 | 6 July – 5 October 2026 | 7 November 2026 |
| Q3 | 6 October 2026 – 5 January 2027 | 7 February 2027 |
| Q4 | 6 January – 5 April 2027 | 7 May 2027 |
| Final declaration | Full 2026–27 tax year | 31 January 2028 |
The new reporting cycle introduces four quarterly submissions for every trade or property business, alongside an end-of-year final declaration. Quarterly updates contain income and expense figures only, with year-end adjustments deferred to the final declaration.
The quarterly updates are not extra tax returns — each quarterly update is a summary of your business income and expenses for that three-month period. You do not need to send invoices or receipts; just the totals in each category. Think of it as a quick health check on the numbers four times a year.
One common worry: a common misunderstanding is that quarterly updates mean paying income tax four times a year — that is not how the system works. MTD means you must report your figures quarterly, but you still pay any tax liabilities only once per year.
What ‘keeping digital records’ actually means in practice
This is the bit that catches people off guard. It is not just about how you file — it is about how you store records day to day.
From April 2026, Making Tax Digital for Income Tax requires self-employed sole traders and landlords with qualifying income over £50,000 to maintain digital records of every individual transaction. Each record must capture the date, amount, and category. Paper receipts stuffed in a shoebox and end-of-year spreadsheet summaries will no longer meet HMRC’s requirements. All records must be stored in MTD-compatible software that can communicate directly with HMRC’s systems.
Relying solely on spreadsheets will not meet MTD standards unless supported by bridging software. For most tradespeople, the cleanest route is cloud accounting software with automatic bank feeds — you link your business bank account, and transactions pull through automatically. You categorise as you go, which takes minutes rather than hours.

The penalty system explained plainly
Here is where people need to pay attention. From April 2026, Making Tax Digital penalties work on a points system, similar to driving licence points.
For each quarterly update or annual tax return deadline that is missed, a taxpayer will receive one penalty point. There is no financial penalty unless you reach the threshold of four points in a two-year period — at that stage you can be charged a financial penalty of £200. You will then receive a further £200 penalty for further late returns unless the points are reset.
The good news for those already in the system: it was announced in the Budget in November 2025 that there will be a ‘soft landing’ for the new penalty regime, meaning no penalty points will be charged for the late filing of quarterly updates due for the first 12 months of Making Tax Digital becoming operational. So the 2026–27 quarterly updates have some grace — but the final declaration due by 31 January 2028 does not. The penalty easement for late filing of quarterly updates during the 2026–27 tax year does not apply to the end-of-year tax return. This means that taxpayers will still receive a penalty point if they do not submit their 2026–27 tax return by the due date.
Use this year to get the system right. The soft landing will not be there from 2027–28 onwards.
What software do you actually need
You need HMRC-recognised software — not just any accounting package, and not a standard spreadsheet on its own. HMRC-approved software is required to submit quarterly updates; spreadsheets alone are not sufficient.
Full cloud accounting software covers everything: invoicing, expense tracking, bank feeds, MTD quarterly updates, the final declaration that replaces the annual Self Assessment tax return, and VAT returns where applicable. Xero, QuickBooks, FreeAgent and Sage Business Cloud are the main UK options.
The software does the heavy lifting once your records are in it. The quarterly submission itself is usually a few clicks — your software formats the data correctly and sends it direct to HMRC. Your accountant can also access your records in real time, which tends to make year-end much less painful.
At Mucka, we integrate directly with Xero, QuickBooks, Sage, and FreeAgent. That means your job records, invoices, and expenses flow from where you manage your work straight into the accounting software that handles your MTD submissions — no double entry, no reconciling two separate systems at quarter-end.
Your action checklist
If you are in scope and have not sorted this yet, here is what to do:
-
Check your qualifying income. Pull your 2024–25 Self Assessment figures (filed by 31 January 2026). Add your sole-trade gross turnover plus any UK property gross income. If the combined total is over £50,000, you are in Phase 1.
-
Choose HMRC-recognised software. Make sure it specifically supports MTD for Income Tax (not just MTD for VAT). Xero, QuickBooks, FreeAgent, and Sage all qualify.
-
Sign up with HMRC. You register directly via your Government Gateway account. Your software provider’s setup guide will walk you through linking the two.
-
Connect your business bank account. Enable the bank feed so transactions pull through automatically. This is the single biggest time-saver.
-
Start recording from 6 April 2026. Digital records need to be in place from the start of the tax year — not just when your first deadline arrives.
-
Diarise the four deadlines. 7 August, 7 November, 7 February, 7 May. Set a recurring reminder two weeks before each one so you are not scrambling.
-
Submit your Q1 update by 7 August 2026. Even with the soft landing in place for this year, it is worth hitting this first deadline cleanly — building the habit matters.
The upside nobody talks about
Most of the coverage around MTD focuses on compliance and penalties. But there is a practical benefit here that tends to get buried.
When you are tracking income and expenses quarterly, you have a running picture of your tax position. Instead of one busy push at the end of January, you report throughout the year and can see an ongoing estimate of tax due. This helps with budgeting for payments, reduces surprises, and makes record-keeping more straightforward when done in near-real time.
For a tradesperson who has ever been hit with a tax bill they were not quite expecting in January, that visibility alone is worth something. No more setting aside the wrong amount. No more end-of-year panic.

FAQ
Does the £50,000 threshold apply to my profit or my turnover?
Thresholds are based on gross income, not profit. That means it is your total invoiced income before you deduct materials, fuel, tools, or any other expenses. If you turned over £55,000 but your profit after expenses was £32,000, you are still in scope.
I operate as a limited company. Does MTD for Income Tax apply to me?
No — not yet. If you trade exclusively through a limited company, you are currently exempt from these specific rules. MTD for Corporation Tax has not been mandated and no start date has been confirmed at the time of writing.
What if I miss a quarterly deadline?
If you miss a quarterly update deadline, you will receive a penalty point. You will not receive a financial fine immediately — you will only be fined a fixed amount (currently £200) once you reach a threshold of points (usually four points for quarterly reporters). During the 2026–27 tax year only, the soft landing means no points are issued for late quarterly updates — but that protection ends from April 2027.
Can I use a spreadsheet?
Not on its own. HMRC’s keep-digital-records rule is the hidden step that catches most sole traders out. The income and expenses you submit each quarter must originate in compatible software or in a spreadsheet linked to bridging software — they cannot be copied across from a paper diary at the end of the quarter. Bridging software is a valid route if you want to keep your spreadsheet, but you will need a compatible tool to handle the actual submission.
When does MTD expand to lower earners?
If your qualifying income is over £30,000 for the 2025–26 tax year, you will need to use MTD from 6 April 2027. If your qualifying income is over £20,000 for the 2026–27 tax year, you will need to use it from 6 April 2028.
