Making Tax Digital Goes Live in 10 Days — Your Complete Compliance Checklist for April 2026

Making Tax Digital for Income Tax is not optional record-keeping advice. It is a legal obligation under the Finance (No.2) Act 2017, finally coming into force after multiple postponements.

The core requirements from 6 April 2026:

• Digital record-keeping: all business income and expenses must be recorded using HMRC-recognised software. Paper ledgers, personal spreadsheets, and shoeboxes of receipts no longer count.
• Quarterly updates: you must submit a summary of income and expenses to HMRC every quarter, within one month of the quarter end. The first deadline for 2026/27 is 7 August 2026.
• End of Period Statement (EOPS): a finalisation for each income source after the tax year ends.
• Final declaration: replaces your annual self-assessment tax return, due by 31 January following the tax year.

The quarterly schedule for 2026/27 runs as follows:

Quarter	Period	Submission Deadline
Q1	6 April – 5 July 2026	7 August 2026
Q2	6 July – 5 October 2026	7 November 2026
Q3	6 October – 5 January 2027	7 February 2027
Q4	6 January – 5 April 2027	7 May 2027

This is a fundamental shift. Rather than reconstructing a year's worth of finances every January, you are reporting in near-real-time. HMRC's stated aim is to reduce the £8.5 billion annual tax gap — the difference between tax owed and tax collected.

The rollout is phased by income threshold, and the net widens fast.

From 6 April 2026 (10 days away): sole traders and landlords with combined gross income above £50,000 from self-employment and/or property. This captures 860,000 taxpayers.

From April 2027: the threshold drops to £30,000. Roughly 1.6 million additional taxpayers join.

From April 2028: the threshold drops again to £20,000. The total reaches approximately 3 million taxpayers.

The income figure is gross, not profit. A landlord with £55,000 in rental income but £20,000 in allowable expenses still qualifies — the threshold tests turnover, not taxable profit.

Both self-employment and property income are combined. A sole trader earning £35,000 from freelancing and £20,000 from a buy-to-let crosses the £50,000 threshold and must comply from April 2026.

Who is exempt? A few narrow categories escape the first wave:

• Limited company directors whose only income is salary and dividends (MTD ITSA targets unincorporated income)
• Individuals without a National Insurance number
• Recipients of blind person's allowance
• Foster carers and kinship carers (exempt until April 2027)
• Non-UK residents with no UK self-employment or property income

If you operate through a limited company and have no sole-trade or rental income, MTD ITSA does not apply to you — though MTD for Corporation Tax is expected to follow in later years.

HMRC maintains an official list of MTD-compatible software — and you must use one of them. Your existing spreadsheet, however detailed, will not satisfy the legal requirement unless it feeds into a recognised bridging product.

Here is how the main options compare for sole traders and landlords:

Software	Monthly Cost	Best For	Free Trial
FreeAgent	£7/month (NatWest/RBS free)	Freelancers, simple sole traders	30 days
Xero Starter	£8/month	Growing businesses, multiple income sources	30 days
QuickBooks Simple Start	£6/month	US-familiar interface, app-heavy users	30 days
Sage Accounting	£7/month	Traditional businesses, accountant integration	30 days
Clear Books	£5/month	Budget-conscious sole traders	30 days
Hammock	Free (landlords)	Property income only	N/A
HMRC MTD app	Free	Very simple affairs	N/A

The sweet spot for most sole traders is £5–£8 per month — and every penny is a tax-deductible business expense. At the 40% higher rate, an £84/year software subscription effectively costs £50.40 after tax relief.

A few decision principles:

If your bank offers free software, take it. NatWest and RBS business account holders get FreeAgent at no cost. That is the strongest value proposition in the market.

If you have a landlord-only portfolio, Hammock is purpose-built and free for basic use.

If your accountant already uses specific software, match them. The efficiency gains from shared access far outweigh any monthly price difference.

If you are choosing from scratch, Xero and QuickBooks have the largest ecosystems of add-ons and integrations. Both connect to over 1,000 third-party apps for invoicing, expenses, and payroll.

Do not leave this decision until April. Most software requires initial setup — connecting bank feeds, categorising historical transactions, configuring tax codes. That setup takes 2–4 hours for a simple sole trade, longer for multiple income sources.

With 10 days until MTD goes live, here is exactly what you need to do — in order of priority.

Days 1–2: Confirm your obligation

Check your 2024/25 self-assessment return. If your combined self-employment and property gross income exceeded £50,000, you are in scope from 6 April 2026. Log into your HMRC online account — HMRC has been sending MTD notices since January 2026, and your account should confirm whether you are mandated.

Days 3–4: Choose and subscribe to software

Pick from the HMRC-compatible list. If you already use accounting software, check it supports MTD ITSA quarterly submissions — most major providers have released updates. If you bank with NatWest or RBS, activate your free FreeAgent account today.

Days 5–6: Connect your bank feeds and set up categories

Link your business bank account and credit cards. Set up income and expense categories that map to self-assessment boxes. If you have both self-employment and property income, configure separate income sources — MTD requires separate tracking.

Days 7–8: Migrate historical data

Import your 2025/26 transactions if your old system allows CSV export. This is not strictly required for MTD (which starts fresh from April 2026), but having continuity helps your accountant and gives you a baseline for comparison.

Days 9–10: Test a submission

Most MTD software includes a test mode or sandbox environment. Run through a mock quarterly update to ensure your software connects to HMRC's API. Better to discover authentication problems now than on 7 August when your first real submission is due.

Ongoing: diarise your quarterly deadlines

Put the four quarterly deadlines in your calendar now. Late submissions attract penalty points under HMRC's new system — and points accumulate.

HMRC has introduced a new points-based penalty system for MTD, replacing the old surcharge model. Understanding it matters because the consequences compound.

For late quarterly submissions, you receive one penalty point per missed deadline. Once you hit the penalty point threshold — four points for quarterly obligations — you receive a £200 fine. Every subsequent late submission also triggers £200, until you bring your compliance up to date and the points reset.

For late payment, the structure bites harder:

• 1–15 days late: no penalty (grace period)
• 16–30 days late: penalty calculated at 2% of tax outstanding at day 15
• 31+ days late: an additional 2% of tax outstanding at day 30, plus a daily rate of 4% per annum on the outstanding balance

At the current Bank of England base rate of 3.75%, HMRC's 4% late payment interest already exceeds the risk-free rate. Delaying tax payments is now more expensive than borrowing to pay on time.

The penalty regime is designed to be proportionate but firm. A sole trader who misses all four quarterly updates in year one accumulates four points, hits the threshold, and pays £200. Miss one more, and it is another £200. The system rewards consistent compliance and punishes serial lateness.

One important detail: reasonable excuse provisions still apply. Genuine illness, bereavement, or HMRC system outages can excuse a late submission — but "I forgot" or "my software was not set up" will not qualify.

Here is where the optimizer's lens matters. MTD is not just a compliance burden — it is a structural change that creates genuine tax planning opportunities for those who engage with it properly.

Quarterly visibility exposes timing opportunities. Under annual self-assessment, most sole traders only discovered their tax position in January — far too late to act. Quarterly reporting means you see your cumulative profit after Q2 (October) and can make informed decisions about:

• Pension contributions: if your Q1–Q2 profits suggest a £60,000+ year, making pension contributions before 5 April reduces your adjusted net income and recovers the personal allowance taper (lost at £1 for every £2 above £100,000). Every £1 contributed between £100,000 and £125,140 effectively saves 60% in tax.
• Capital expenditure timing: the Annual Investment Allowance gives 100% first-year relief on qualifying plant and machinery up to £1 million. If Q3 figures show higher-than-expected profits, bringing forward equipment purchases to March saves tax at your marginal rate.
• Trading loss planning: if one quarter shows a loss, quarterly data helps you decide whether to carry it back against the previous year's profits (for an immediate refund) or forward against future income.

Improved accuracy reduces overpayment. HMRC estimates that the tax gap includes billions in both underpayment and overpayment. Regular digital reporting catches deductible expenses that annual filers forget — bank charges, professional subscriptions, use-of-home allowances, mileage. A sole trader claiming the simplified £6/week working-from-home allowance saves £312/year in taxable income. At the 40% rate, that is £124.80 — more than the cost of MTD software.

With the personal allowance frozen at £12,570 since 2021/22 — and not due to rise until at least 2028/29 — fiscal drag is pushing more sole traders into the higher rate band. Class 4 NI adds another 6% on profits between £12,570 and £50,270, then 2% above that. Every legitimate deduction captured through better digital records directly reduces this combined marginal burden of 46%.

Landlords face unique MTD considerations that differ from sole traders.

Property income and self-employment income are combined for the threshold test but reported separately within MTD. A landlord with a £55,000 rental portfolio and no self-employment income is in scope. So is someone with £30,000 in freelance earnings and £25,000 in rent.

Quarterly reporting for rental income requires tracking:

• Gross rents received (not invoiced — the cash basis is default for property income under £150,000)
• Allowable expenses: mortgage interest (at the 20% basic rate credit since the Section 24 restriction), repairs, insurance, letting agent fees, ground rent, service charges
• The property allowance of £1,000 — though this is rarely optimal for landlords above the MTD threshold

For landlords with mortgages, MTD's quarterly reporting makes the Section 24 mortgage interest restriction more visible. You can no longer offset mortgage interest against rental income directly — instead, you receive a 20% tax credit. Higher-rate taxpayers with large mortgages may find their quarterly updates show apparent "profits" that feel disconnected from their actual cash position.

This is precisely the scenario where good software pays for itself. Tools like Hammock or Xero's property module calculate the Section 24 restriction automatically and show your true tax liability, not just the headline profit figure.

If you are a landlord considering incorporation to escape Section 24, the MTD obligation adds another factor to the decision. Limited companies are outside MTD ITSA — but incorporation triggers Stamp Duty Land Tax on property transfers and Capital Gains Tax on the disposal. Run the numbers with an accountant before making that leap, and review our tax planning hub for the full picture.

MTD does not eliminate the need for an accountant — but it changes the relationship.

Under the old model, many sole traders handed their accountant a bag of receipts in January and received a completed self-assessment in return. That model is dead. MTD requires real-time digital records, and the quarterly submission cadence means your accountant needs access to your software throughout the year.

Three practical models are emerging:

Full delegation: your accountant manages your MTD software, categorises transactions, and submits quarterly updates on your behalf. This is the closest to the old model but costs more — expect £150–£300/month for a fully managed service.

Collaborative: you maintain day-to-day records in shared software, and your accountant reviews and submits each quarterly update. Typically £80–£150/month.

Self-service with annual review: you handle all quarterly submissions yourself, and your accountant reviews the end-of-year figures and final declaration. The most cost-effective at £500–£1,000/year, but requires confidence with software.

Whichever model you choose, agree it now — not in August when your first quarterly update is due. Accountancy practices report heavy demand for MTD onboarding, and capacity is finite.

For student loan repayments, note that MTD does not change how plan repayments are calculated on self-employment income — they are still assessed annually. But the quarterly profit visibility helps you estimate your January payment on account more accurately.

Misinformation about MTD has circulated for years. Here is the reality.

"MTD means I pay tax quarterly." No. You report quarterly. Tax payment dates are unchanged — payments on account remain due on 31 January and 31 July, with a balancing payment on the following 31 January. The quarterly updates are information submissions, not payment triggers.

"I can keep using spreadsheets." Only if they connect to HMRC via bridging software that is on the compatible list. A standalone Excel file does not qualify. Some bridging tools exist that let you continue in spreadsheets and submit digitally, but this defeats much of the benefit.

"My turnover is under £50,000, so I am safe." For now. The threshold drops to £30,000 in April 2027 and £20,000 in April 2028. If you are close to the threshold, starting early with MTD-compatible software is pragmatic — you avoid a rushed transition later and gain the record-keeping benefits immediately.

"MTD replaces self-assessment." Not entirely. The final declaration at year-end is effectively the replacement for the self-assessment return, but it exists within the MTD framework. You do not file a separate SA100 — the MTD final declaration covers the same ground.

"I can opt out if I find it too difficult." No. If your income exceeds the threshold, compliance is mandatory. HMRC has stated there are no opt-out provisions, though reasonable excuse claims can mitigate penalties for genuine difficulties.

"This only affects the self-employed." MTD ITSA affects anyone with qualifying self-employment or property income above the threshold — including employed people with a side business or rental property. If your PAYE salary is £80,000 but you also earn £5,000 from a buy-to-let, you are not in scope at the £50,000 threshold (only the property income counts). But if that property income grows above £50,000, or you add self-employment income that pushes the combined total over, MTD applies.

MTD ITSA is not an isolated project. It is phase two of a decade-long digitisation programme that started with MTD for VAT in April 2019 — which now covers 2.1 million VAT-registered businesses.

The VAT rollout provides a useful preview. Initial resistance was high, compliance costs were front-loaded in year one, and HMRC's systems experienced teething problems. By year three, the process was routine for most businesses, and HMRC reported improved accuracy in VAT returns.

Expect a similar trajectory for MTD ITSA. The first year will involve friction — software setup, unfamiliar workflows, and the occasional HMRC API outage. By 2028, quarterly digital reporting will feel as normal as filing self-assessment online does today.

HMRC's longer-term roadmap includes:

• MTD for Corporation Tax: expected from April 2028 at the earliest, bringing limited companies into the quarterly reporting framework
• Pre-populated returns: HMRC aims to use employer RTI data, bank interest reports, and dividend notifications to pre-fill your quarterly updates, reducing manual entry
• Single Customer Account: a unified HMRC portal replacing the current patchwork of personal tax account, business tax account, and Government Gateway

For marriage allowance claims, the MTD framework does not change eligibility — but the improved visibility of household income makes it easier to spot whether a transfer benefits you. If one partner earns under the personal allowance of £12,570 and the other is a basic rate taxpayer, the £1,260 transferable allowance saves £252/year.
