Introduction
Making Tax Digital is the biggest change to UK tax reporting in a generation. For many sole traders and landlords, it means the end of a single annual tax return and the beginning of quarterly digital reporting directly to HMRC — a significant shift in how you manage your finances throughout the year.
If you earn above the threshold, this is no longer something to plan for in the future. The first phase of MTD for Income Tax Self Assessment went live in April 2026, and the requirements will broaden in the years ahead.
This guide explains everything sole traders need to know: what MTD actually means in practice, who is affected and when, what the quarterly deadlines look like, what software you need, and how to make the transition as straightforward as possible.
What Is Making Tax Digital?
Making Tax Digital (MTD) is HMRC’s programme to modernise the UK tax system by requiring businesses and individuals to keep digital financial records and submit tax information digitally throughout the year — rather than filling in a paper or online tax return once a year.
The goal is to reduce errors, make tax more accurate in real time, and give both taxpayers and HMRC a clearer picture of income and liabilities throughout the year rather than looking backwards after the event.
MTD has been rolling out in phases:
- MTD for VAT — introduced in 2019 for larger businesses, extended to all VAT-registered businesses in 2022. If you’re VAT-registered, you’re already required to use MTD-compatible software to submit your VAT returns.
- MTD for Income Tax Self Assessment (MTD ITSA) — this is the big change for sole traders. It replaces the annual Self Assessment tax return with quarterly digital updates to HMRC.
MTD for Income Tax: Who Is Affected and When?
MTD for Income Tax Self Assessment is being rolled out in stages based on turnover:
From April 2026 (already in force): Sole traders and landlords with total gross income above £50,000 per year are now required to comply with MTD for Income Tax.
From April 2027: The threshold drops to £30,000 — bringing a significantly larger group of sole traders and landlords into the scheme.
From April 2028 (proposed): HMRC has indicated the threshold will drop further to £20,000, though the precise details and any exemptions are subject to confirmation. If you’re below the current thresholds, it is still worth preparing — particularly if your income is growing.
Partnerships: General partnerships are not currently included in MTD ITSA. HMRC has confirmed they will be brought in at a future date, though no specific timeline has been confirmed.
Important: The income figure that determines whether you’re affected is your gross income — your total turnover before any expenses are deducted. Not your profit.
What Changes Under MTD for Income Tax?
Under the current Self Assessment system, you report your income once a year — submitting your tax return by 31 January following the end of the tax year.
Under MTD for Income Tax, that annual process is replaced by a new four-part cycle:
1. Quarterly Updates (4 times per year)
Every quarter, you submit a summary of your income and expenses to HMRC. This is not a full tax return — it’s a digital update of your running totals. HMRC uses these to give you an estimate of your likely tax bill throughout the year.
The quarterly periods are:
| Quarter | Period | Submission deadline |
|---|---|---|
| Q1 | 6 April – 5 July | 5 August |
| Q2 | 6 July – 5 October | 5 November |
| Q3 | 6 October – 5 January | 5 February |
| Q4 | 6 January – 5 April | 5 May |
There is also an option to use calendar quarterly periods (1 April to 30 June etc.) — your software provider can advise on which aligns best with your business.
2. End of Period Statement (EOPS)
At the end of the tax year, you submit an End of Period Statement — a finalised summary of your income and expenses for the full year. This is where you make any accounting adjustments, claim allowances, and confirm your figures are correct.
The deadline for the EOPS is 31 January following the end of the tax year — the same date that currently applies to Self Assessment returns.
3. Final Declaration
The Final Declaration replaces the Self Assessment tax return. It’s submitted after your EOPS and confirms your total tax liability for the year, including any other sources of income (employment, dividends, rental income, etc.).
Again, the deadline is 31 January.
In Practice
For a sole trader with a straightforward business, the process looks like this:
- Keep your income and expenses recorded digitally throughout the year in MTD-compatible software
- Every quarter, your software generates a summary and submits it to HMRC in a few clicks
- At the end of the year, you complete and submit your EOPS and Final Declaration
The quarterly updates themselves take minutes once your records are up to date. The key discipline is keeping your records current throughout the year — which is where the right software makes a significant difference.
What You Need to Do to Comply
Step 1 — Choose MTD-Compatible Software
You cannot comply with MTD for Income Tax using spreadsheets alone or paper records. You must use HMRC-approved software that can submit quarterly updates, your EOPS, and your Final Declaration directly to HMRC.
HMRC maintains a list of approved software on its website. The main options trusted by UK sole traders are:
- FreeAgent — particularly strong for sole traders, includes Self Assessment support, free with NatWest/RBS/Mettle business accounts (£19/month otherwise)
- QuickBooks — excellent MTD ITSA support, Sole Trader Plus plan at £10/month
- Xero — comprehensive MTD support, from £16/month (Ignite plan)
- Sage — strong UK payroll and accounting integration, Sage Accounting from £18/month, Sage Sole Trader from free then £7/month
All four platforms are on HMRC’s approved list and can handle the full MTD ITSA workflow including quarterly submissions, EOPS, and Final Declaration.
Step 2 — Start Keeping Digital Records
From your first MTD-mandated quarter, all income and expenses must be recorded digitally in your software. This means:
- Recording every sale and invoice in your software as it happens
- Logging every business expense with the correct category
- Connecting your business bank account so transactions feed in automatically (most MTD software supports this)
- Keeping receipts — most platforms let you photograph and attach receipts to transactions via their mobile app
If you’ve been keeping records on paper or in a spreadsheet, now is the time to transition to proper software. Doing so before your mandated start date gives you time to get comfortable with the system before your first quarterly submission is due.
Step 3 — Register with HMRC for MTD ITSA
You’ll need to sign up for MTD for Income Tax through your HMRC online account or Government Gateway. Your software provider will typically guide you through this process — most have step-by-step setup wizards that handle the HMRC registration as part of onboarding.
You must register before your first quarterly deadline. HMRC recommends doing so at least a week before your deadline to avoid any last-minute technical issues.
Who Is Exempt from MTD for Income Tax?
Not everyone is required to comply with MTD for Income Tax. You may be exempt if:
- Your total gross income from self-employment and property is below the relevant threshold (currently £50,000 for April 2026, dropping to £30,000 from April 2027)
- You are unable to use digital tools due to age, disability, or a remote location without reliable internet access
- You have a religious objection to using electronic communications
- You are in a trust, estate, or other entity type not currently included in MTD ITSA
If you believe you qualify for an exemption, you need to apply to HMRC directly. Exemptions are not automatic — you must request one and have it granted before your compliance deadline.
How Does This Affect Your Tax Payment Dates?
MTD for Income Tax changes how you report your income, but it does not currently change when you pay your tax. You still pay any tax owed by 31 January following the end of the tax year, with the possibility of a payment on account on 31 July.
However, the quarterly updates mean HMRC can give you a running estimate of your expected tax bill throughout the year — which should make it easier to set money aside rather than facing a large unexpected bill in January.
Common Questions About MTD
Does MTD for Income Tax replace Self Assessment completely?
For those within scope, yes — MTD ITSA replaces the annual Self Assessment tax return with quarterly updates plus the End of Period Statement and Final Declaration. The Final Declaration covers much of the same ground as a Self Assessment return, but it is submitted via your MTD software rather than the HMRC Self Assessment portal.
If you have income from sources other than self-employment (such as employment, dividends, or savings interest), you’ll still declare those through the Final Declaration process.
Do I need an accountant for MTD?
You don’t legally need one, but many sole traders find an accountant helpful — particularly in the first year of MTD. Your accountant can submit your quarterly updates, EOPS, and Final Declaration on your behalf if you authorise them in your MTD software. This can be a sensible arrangement while you’re getting used to the new system.
What happens if I miss a quarterly deadline?
HMRC has introduced a points-based penalty system for MTD ITSA. Each missed submission earns a penalty point. Once you accumulate a set number of points, you receive a financial penalty. The threshold is four points for quarterly filers — so you have some tolerance for occasional late submissions, but persistent lateness will result in fines.
What if my income changes and I drop below the threshold?
If your income drops below the relevant threshold in a subsequent year, you may be able to leave MTD ITSA. HMRC has processes for this, but you cannot simply stop submitting — you need to contact HMRC and confirm your position. Your software provider can advise on the process.
Preparing for MTD: A Practical Checklist
If you’re not yet using MTD-compatible software, here’s what to do now:
- Check whether you’re in scope — calculate your total gross income from self-employment and any property you rent out. If it’s over £50,000, you’re already within the April 2026 rules
- Choose your software — FreeAgent, QuickBooks, Xero, and Sage are all reliable choices. Most offer free trials
- Connect your bank account — setting up automatic bank feeds makes record-keeping significantly easier
- Register with HMRC for MTD ITSA — do this through your software or Government Gateway before your first quarterly deadline
- Set quarterly reminders — put the four submission deadlines in your calendar so nothing slips
- Talk to your accountant — if you use one, discuss whether they’ll handle submissions on your behalf or whether you’ll do them yourself
Conclusion
Making Tax Digital for Income Tax is a significant change — but for most sole traders using the right software, the practical impact is manageable. Quarterly submissions are quick once your records are kept up to date, and the benefit of seeing a running tax estimate throughout the year is genuinely useful for cash flow planning.
The biggest risk is leaving it too late. If you’re above the threshold and haven’t yet set up MTD-compatible software, now is the time to act. FreeAgent, QuickBooks, Xero, and Sage all support the full MTD ITSA workflow and can get you compliant quickly — most offer free trials so you can find the right fit before committing.
