Making Tax Digital for Income Tax: What You Actually Need to Know Now It Is Live
The programme was delayed five times before it finally went live in April 2026. Here's what is in force now, what the penalties are, and what changes next.
Quick answer
Making Tax Digital for Income Tax has been mandatory since 6 April 2026 for sole traders and landlords with gross qualifying income over £50,000, dropping to £30,000 in April 2027 and £20,000 in April 2028. Those in scope must keep digital records and submit cumulative quarterly updates through HMRC-recognised software by 7 August, 7 November, 7 February and 7 May, plus a year-end tax return (the Final Declaration) through the same software by 31 January. Late submissions earn penalty points, with a £200 fine at four points, though no points are given for late quarterly updates in the 2026/27 tax year. Partnerships are deferred indefinitely.
- MTD ITSA has been live since 6 April 2026 at £50,000 gross income, falling to £30,000 in 2027 and £20,000 in 2028.
- The threshold tests gross turnover, not profit, and quarterly updates are cumulative year-to-date figures.
- Four late-submission points trigger a £200 penalty; late quarterly updates earn no points in 2026/27, but do from 2027/28.

The short version
Since 6 April 2026, if you're a sole trader or landlord with gross business and property income over £50,000, you must keep digital records and submit quarterly summaries to HMRC using compatible software. This isn't optional and it isn't coming: it is the regime you are filing under right now. The first quarterly update of the 2026/27 tax year, covering 6 April to 5 July, was due by 7 August 2026, and the second, covering 6 April to 5 October, is due by 7 November 2026. HMRC says more than 436,000 sole traders and landlords had sent their first update by 12 August, and from September 2026 it began signing up people who should be using MTD but had not joined.
The programme was delayed five times since its original 2018 target date, which created a very understandable "cry wolf" effect: every accountant in the country had been told to prepare for it at least three times. There is no sixth delay. It went live on schedule in April 2026, and the question is no longer whether to prepare but whether your clients in scope are actually filing.
Who is affected (and who isn't)
MTD ITSA applies to individuals with qualifying income from self-employment and/or property. The threshold test is based on gross income - turnover, not profit. If your client takes in £55,000 but spends £40,000 on materials, they're still in scope despite only making £15,000.
The qualifying income includes:
- Self-employment income (all trades combined)
- UK property income
- Overseas property income
It does not include employment income, pensions, dividends, savings interest, or investment income. A landlord earning £45,000 in rental income and £80,000 from their PAYE job is not caught at the £50,000 threshold - only the rental income counts.
Phase-in schedule
Threshold Timeline
| 6 April 2026 | Gross qualifying income above £50,000 |
| 6 April 2027 | Gross qualifying income above £30,000 |
| 6 April 2028 | Gross qualifying income above £20,000 |
That final £20,000 threshold was confirmed in the Spring Statement 2025. HMRC's own estimate is that around 975,000 more people sit in the £20,000 to £30,000 band, including many landlords with a single let property.
Who's exempt
Partnerships have been punted into the long grass. HMRC remains "committed" to bringing them in, but no date has been set. For now, partnership income is out of scope entirely.
Automatic exemptions apply to trustees, personal representatives of deceased persons, Lloyd's underwriters (in respect of their underwriting), and anyone without a National Insurance number on 31 January before the tax year starts.
You can also apply for digital exclusion if age, disability, location (poor broadband), or religious beliefs make digital compliance impractical. HMRC will not, however, accept "I prefer paper" or "I find computers stressful" as grounds for exemption. HMRC aims to respond to an application within 28 days.
What quarterly reporting actually means
Four times a year, you submit a summary of income and expenses to HMRC via compatible software. These are not mini tax returns. No capital allowance calculations, no pension relief claims, no sideways loss relief. Just the numbers.
The data categories mirror the existing Self Assessment supplementary pages - SA103F for self-employment and SA105 for property. In practice, this means reporting totals for categories like: turnover, cost of goods sold, staff costs, travel, premises costs, repairs, professional fees, and other allowable expenses.
Standard quarter dates
You can elect to use calendar quarters instead of tax year quarters, which is tidier and aligns better with VAT quarters. The election must be made before your first update is submitted. Filing deadlines remain the same either way.
Cumulative Reporting
One important quirk: the updates are cumulative. Each submission shows year-to-date figures, not just that quarter's activity. So your Q3 submission contains all income and expenses from 6 April through to 5 January. If you got something wrong in Q1, you can correct it in Q2 without penalty.
Separate submissions per business
A sole trader who also rents out a property will need eight quarterly submissions per year - four for the trade, four for the property. If someone has two trades and a property, that's twelve. This is the bit that catches people off guard.
Final Declaration
After the four quarterly updates, there's a Final Declaration due by 31 January following the tax year. It does the job of the old Self Assessment return, filed through your MTD software. It's where you declare other income (employment, dividends, savings), claim reliefs, make adjustments, and confirm everything is correct. The End of Period Statement (EOPS) that was originally planned has been scrapped, and its contents were absorbed into the Final Declaration. HMRC's own guidance now simply calls this year-end step the tax return.
The software question
HMRC maintains a list of recognised software providers. There are hundreds of them, ranging from the big players (Xero, QuickBooks, Sage, FreeAgent) to specialist products aimed at landlords or sole traders with simple affairs.
IQ Books, ReconcileIQ's own accounting software, is one of them, and it is worth a look if you are setting up a sole trader for quarterly filing. The rest of the suite is built into it (CodeIQ's eight-phase AI coding, MatchIQ's reconciliation, the 44 LedgerIQ analysis modules and the RiQ assistant), so digital records are kept properly rather than reconstructed at year end. It is open to every account. The free tier gives one organisation with the whole ledger, multi-currency and MTD VAT and Income Tax filing included. Using it by hand never costs credits; only automation, such as CodeIQ coding your bank lines, draws on the 1,000 free credits every account starts with. Paid plans start at £10 a month, additional organisations are £5 a month each, and the only paid features are emailing invoices and reminders from our domain, CIS300 and Companies House filing, the invoice design studio beyond your logo and brand colour, removing the IQ Books footer from invoices, and extra users beyond the owner and their accountant. One-click migration from Xero, QuickBooks or Sage carries across the opening trial balance, contacts and outstanding invoices. To be clear about scope: IQ Books files MTD VAT returns and MTD Income Tax quarterly updates for sole traders today, and is on HMRC's list of software for Making Tax Digital for Income Tax. UK and foreign property income and the year-end tax return (Final Declaration) are not supported yet, so landlords and the year-end return need other software for now. Explore IQ Books.
The key requirements:
Digital record-keeping
Every transaction must be recorded digitally - in software or a spreadsheet. Paper ledgers are dead, at least for anyone in scope.
API connection to HMRC
Your software must submit quarterly updates directly to HMRC's systems. If you use spreadsheets, they must connect through API-enabled bridging software. You cannot email a spreadsheet to HMRC.
Digital links
Data must flow digitally from the source transaction all the way to the submission. No retyping numbers from one system to another.
You do not have to scan and store receipts digitally. The underlying evidence can still be paper. But the accounting records themselves must be digital.
For businesses below the VAT threshold, there's a concession: they can use the simplified "three-line accounts" format (income, expenses, profit/loss) rather than the full category breakdown. This helps smaller landlords and micro-businesses.
What this means practically
If your client currently records everything in a desk drawer and hands you a carrier bag of receipts every January, that workflow ends on their MTD start date. They need to be recording income and expenses digitally, at minimum quarterly, in something that can talk to HMRC.
The silver lining is that the quarterly rhythm forces better record-keeping habits. Bank reconciliation - matching bank transactions against recorded income and expenses - becomes a quarterly discipline rather than an annual panic. That's arguably the single biggest operational change for most small businesses, and the one most likely to surface errors before they compound over twelve months.
How this differs from MTD for VAT
MTD for VAT has been mandatory for all VAT-registered businesses since April 2022, so most accountants and bookkeepers have already lived through one digital transition. MTD ITSA is similar in principle - digital records, compatible software, regular submissions - but differs in several important ways:
MTD for VAT
Threshold: VAT registration (£90,000)
Reporting: Periodic (that quarter only)
Content: Output tax minus input tax
Registration: Automatic via VAT reg
Penalty regime: Points-based (active since 2023)
MTD for Income Tax
Threshold: £50K gross income (dropping to £20K)
Reporting: Cumulative (year-to-date)
Content: Full income & expense breakdown
Registration: Separate sign-up required
Penalty regime: Points-based (first-year grace for 2026/27)
Being signed up for MTD for VAT does not automatically enrol you for MTD ITSA. They're distinct services with separate sign-ups. Many people caught by MTD ITSA will not be VAT-registered at all.
Penalties: the points system
The old HMRC penalty regime - a single fine for a late return - has been replaced by a points-based system. Think of it like a driving licence, except HMRC isn't going to offer you a speed awareness course.
Late submission penalties
Points accumulation
Each missed deadline earns one penalty point. Points accumulate across all submission types (quarterly updates and the Final Declaration).
The threshold: 4 points
When you hit 4 points: £200 penalty. Each further late submission: another £200.
Clearing points
Below the threshold, each point is removed automatically 24 months after the missed deadline. Once you reach the threshold, points stop expiring on their own: to clear them you need 12 months of on-time quarterly updates and returns, plus any outstanding submissions from the previous 24 months.
Late payment penalties
Payment Penalties Are Harsher
These apply to tax paid late after the year-end return (payments on account are not penalised) and are significantly steeper than submission penalties. The 2026/27 rates are:
- Up to 15 days late: No penalty (but interest runs from day 1)
- 16 to 30 days late: 3% of the amount outstanding at day 15
- Day 31+: A further 3% of the outstanding amount, plus a daily penalty accruing at 10% per annum until paid
From 2027/28 the two percentage charges rise to 4% each. Late payment interest is calculated at the Bank of England base rate plus 4% (increased from 2.5% in April 2025), running from the day after the due date.
The first-year concession
Soft Landing for 2026/27
HMRC is charging no penalty points for late quarterly updates in the 2026/27 tax year. This is a meaningful concession: essentially a year to get your systems working without being penalised for teething problems.
Late payment gets a smaller, one-off easing: in your first year under the new penalties, no penalty is charged if you pay in full, or set up a payment plan, within 30 days of the due date rather than 15. Interest still runs from day one. And the points concession is tied to the 2026/27 tax year only, so those joining in April 2027 (the £30,000 threshold) earn points from their first quarter.
Also worth noting: you cannot file your 2026/27 Final Declaration unless all four quarterly updates have been submitted. So "I'll just skip the quarterlies and file everything at the end" is not a viable strategy.
What accountants should be telling their clients right now
If you have clients who are sole traders or landlords with gross income above £50,000, the clock is already ticking. Here's a practical checklist of conversations to have now, and again with the £30,000 cohort before April 2027:
Identify who is in scope
Run through your client list. Anyone with combined self-employment and property gross income over £50,000 is in the first wave. Don't forget overseas property income counts. Don't forget that the threshold test is on turnover, not profit. Then look at the £30,000 bracket - those clients are only twelve months behind.
Get them on software now, not in March
The worst possible time to migrate a client onto new software is the week before a quarterly deadline. If they are not already on a digital bookkeeping platform, that transition is now overdue rather than upcoming, and the sooner it happens the less of the current quarter has to be reconstructed after the fact. Clients currently using spreadsheets need to understand that their spreadsheet either needs API-enabled bridging software, or they need to move to a proper bookkeeping product. "I have a spreadsheet" is only half the answer.
Discuss the workflow change
Quarterly reporting means quarterly bookkeeping. The old model - ignore everything for eleven months, then reconstruct the year from bank statements and receipts in January - doesn't survive contact with MTD ITSA. Clients need to understand that transactions must be recorded at least quarterly, and realistically more often than that if the quarterly submission is going to be anything other than a scramble.
Set expectations on fees
More frequent reporting means more frequent work, which means fees need to reflect the new reality. Some firms are moving to monthly retainers. Others are restructuring their engagement letters to include quarterly submissions as a distinct service line. Either way, the conversation about pricing needs to happen before the work starts, not after the first invoice arrives.
Volunteer the next cohort early
Voluntary sign-up is open. Clients in the £30,000 to £50,000 band, who must join in April 2027, can volunteer now and test your software, your workflows, and your assumptions against real HMRC systems, and volunteers get no penalties for late quarterly updates. It's far better than discovering a problem in August 2027 when their first deadline is bearing down.
Check their threshold annually
Income fluctuates. A landlord at £48,000 in 2025/26 might be at £52,000 in 2026/27. The threshold test applies to the qualifying tax year (broadly, the tax year two years before), so clients near the boundary need monitoring. HMRC will write to taxpayers they believe are in scope, but relying on HMRC to tell you is not a practice management strategy.
Talk about penalties early
Clients respond to concrete consequences. "You'll need to submit quarterly" is abstract. "Miss four deadlines and you'll get a £200 fine, and then £200 for every subsequent late submission, and if you pay late there's a 3% penalty from day 16, another 3% from day 31, and a 10% a year charge on top until it's paid": that tends to concentrate the mind.
The bigger picture
MTD ITSA is the most significant change to income tax administration since Self Assessment launched in 1996/97. It transforms the UK's income tax system from an annual reckoning into something closer to real-time reporting.
HMRC's stated objective is to reduce the "tax gap" - the difference between what's owed and what's collected. The theory is straightforward: if people record income and expenses as they go and report quarterly, errors and omissions are caught sooner, tax liabilities are more accurate, and fewer people end up with unexpected bills.
Whether the reality matches the theory depends entirely on execution. The five delays haven't inspired universal confidence. The software ecosystem is still maturing. And the sheer number of small landlords who are about to be swept into quarterly digital reporting at the £20,000 threshold in 2028 is a logistical challenge that nobody has fully grappled with yet.
But the direction is set and the legislation is in force. For anyone with gross self-employment or property income over £50,000, this is no longer something to plan for. It is the current filing year, and the clock on the first quarterly deadline is already running.
The Bottom Line
The practices handling this smoothly are the ones that had these conversations with clients last year, tested their software before April, and built quarterly workflows into their service model. The ones struggling are the ones that waited for a sixth delay that never came. If you are in the second group, the recovery job is the same as the preparation job was, just compressed: get every client in scope onto digital records, reconstruct the quarters that have already closed, and file the 7 November update on time.
Quarterly reconciliation at scale?
MTD ITSA means reconciling every client's books every quarter, not once a year. If you're managing more than a handful of clients, that's a lot of bank matching.

Frequently Asked Questions
When does MTD for Income Tax start?
MTD for Income Tax Self Assessment began on 6 April 2026 for self-employed individuals and landlords with qualifying income above £50,000. It is live now: the first quarterly update for the 2026/27 tax year was due by 7 August 2026, and the second is due by 7 November 2026. Those with income above £30,000 join from April 2027.
What do I need to do to comply with MTD for Income Tax?
You need MTD-compatible software to keep digital records of income and expenses, submit quarterly updates to HMRC, and file a Final Declaration annually.
What are the penalties for not complying with MTD ITSA?
Late submission penalties use a points-based system. You receive a point for each late quarterly update. After reaching the threshold (4 points for quarterly obligations), a £200 penalty applies, and another £200 for each subsequent late submission. No points are given for late quarterly updates in 2026/27; they apply from 2027/28.
Does MTD for Income Tax affect limited companies?
No. MTD for ITSA applies to self-employed individuals and landlords, not limited companies. HMRC said in its July 2025 transformation roadmap that it does not intend to introduce MTD for Corporation Tax.
