MTD for Sole Traders: Everything You Need to Know in 2026
MTD for sole traders starts April 2026 for income over £50,000. Learn who is affected, what changes, common mistakes, allowable expenses, and how to get ready.
- MTD for sole traders means quarterly digital filing instead of one annual Self Assessment return
- From April 2026, sole traders earning over £50,000 gross must comply. The £30,000 threshold follows in 2027 and £20,000 in 2028
- You need HMRC-compatible software to keep digital records and submit quarterly updates
- The day-to-day change is small: a few minutes per week reviewing transactions, not hours of bookkeeping
MTD for Sole Traders: Everything You Need to Know in 2026
Making Tax Digital changes how sole traders report income and expenses to HMRC. Instead of filing one Self Assessment return each January, you will submit quarterly updates throughout the year using digital software.
If you are self-employed and earn above the threshold, this is no longer optional. MTD for Income Tax Self Assessment is now law, and the first group of sole traders must comply from April 2026.
This guide covers everything you need to know: who is affected, what actually changes in your daily routine, the expenses you can claim, and how to get ready without the stress.
- Sole Trader
- A self-employed individual who runs their own business as an individual rather than through a limited company or partnership. For MTD purposes, sole traders report their business income and expenses separately from any employment income and must file quarterly if their gross self-employment income exceeds the relevant threshold.
What MTD Means for Sole Traders
Under the current system, most sole traders file a single Self Assessment tax return each year by 31 January. You can keep records however you like (notebooks, spreadsheets, shoeboxes of receipts) and submit everything in one go.
Making Tax Digital replaces this with a different approach:
- Digital records: Your income and expenses must be stored in HMRC-compatible software, not just on paper or in a basic spreadsheet
- Quarterly updates: Four times a year, your software submits a summary of your finances to HMRC
- End of Period Statement: After your fourth quarterly update, you confirm your annual figures are complete
- Final Declaration: This replaces the Self Assessment return and calculates your final tax liability
The quarterly updates are not full tax returns. They are progress reports, summaries of what you have earned and spent so far. Think of them as brief check-ins rather than the full annual exercise.
One important distinction: MTD for Income Tax applies to sole traders and landlords. If you run a limited company, you are not affected by MTD ITSA (limited companies have separate Corporation Tax requirements). This guide focuses specifically on sole traders.
Which Sole Traders Are Affected (and When)
MTD is phased in based on your gross income, that is your total turnover before expenses, not your profit. The thresholds and dates are:
April 2026: Income over £50,000
The first wave. If your gross self-employment income exceeds £50,000 in the 2024-25 tax year, you must file quarterly from April 2026. This typically includes established tradespeople, experienced consultants, busy freelancers, and sole traders with strong client bases.
April 2027: Income over £30,000
The second wave catches many more sole traders. A plumber earning £35,000 gross, a tutor with £32,000 in fees, a delivery driver bringing in £31,000. All fall into this group. Check the MTD deadlines for every date you need to know.
April 2028: Income over £20,000
The third wave brings in sole traders with more modest incomes. At this threshold, the vast majority of full-time self-employed workers will be within scope.
Below £20,000
HMRC has not yet set a mandatory date for sole traders earning under £20,000. You can still use MTD software voluntarily, and many find it helpful for keeping records organised even without the legal requirement.
The threshold that catches people out
Your qualifying income is gross turnover, not profit. If your business brings in £55,000 but your expenses are £20,000 (giving you a £35,000 profit), you are still in the April 2026 group based on that £55,000 gross figure.
Also, if you have both self-employment income and property income, these are combined for the threshold. A plumber earning £30,000 from plumbing and £25,000 from a rental property has a combined income of £55,000, putting them in the first wave.
What Changes in Your Day-to-Day
Here is the honest truth: for most sole traders, the daily change is smaller than you expect. MTD does not mean four times as much work. It means spreading a small amount of work across the year instead of cramming it all into January.
The old way
- Throw receipts in a drawer all year
- Spend a stressful weekend in January sorting everything out
- Hire an accountant or struggle through Self Assessment
- Hope you have not missed anything deductible
The MTD way
- Spend a few minutes each week reviewing transactions in your app
- Your software categorises expenses and pulls bank data automatically
- File each quarter with a tap because your records are already up to date
- Know roughly what you owe throughout the year, not just at year-end
The shift is from one big annual task to a small ongoing habit. Five minutes a week beats five hours in January. And because your records are up to date, each quarterly submission takes minutes, not hours.
We want to make it easier for businesses and individuals to get their tax right first time, reducing the need for them to correct errors later.
The key is choosing Making Tax Digital software that handles the heavy lifting. With bank feeds and AI categorisation, most of the work happens automatically. You are reviewing and confirming, not manually entering every transaction.

The Sole Trader MTD Checklist
Getting ready for MTD does not need to be complicated. Follow these steps in order:
1. Check your income threshold
Look at your Self Assessment return for the 2024-25 tax year. What is your gross self-employment income (before expenses)? If it exceeds £50,000, you are in the April 2026 group. Between £30,000 and £50,000, you have until April 2027.
If you also have property income, add that to your self-employment income. The combined figure determines your threshold.
2. Choose your MTD software
Pick HMRC-compatible software that suits your needs and budget. For most sole traders, a purpose-built tool like TapTax (starting at £4.99 per month) is simpler and cheaper than full accounting software. Compare your options in the best MTD software for sole traders guide.
3. Connect your bank account
Most MTD software connects to your bank via Open Banking. This pulls your transactions in automatically so you do not need to enter them by hand. Set this up as soon as you have chosen your software.
4. Start recording and categorising
Begin reviewing and categorising your income and expenses. Even if MTD is not mandatory for you yet, building the habit now means you are comfortable with the process before it counts. Aim for a few minutes each week. Do not let transactions pile up.
5. File your first quarterly update
When your first quarter ends, review the summary your software has prepared and submit it to HMRC. With up-to-date records, this should take under five minutes. Your software handles the formatting and transmission.
6. Keep going
After the first quarter, it becomes routine. Review transactions weekly, file quarterly, and let the software handle the rest. The End of Period Statement and Final Declaration come at year-end, and your software guides you through those too.
Common Sole Trader Mistakes with MTD
Based on what HMRC has flagged and what accountants report, these are the most common pitfalls for sole traders:
Forgetting cash income
If customers pay you in cash, those transactions will not appear in your bank feed. You need to record cash income manually in your software. Failing to include cash payments is a common error that can trigger HMRC enquiries.
Mixing personal and business expenses
If you use one bank account for everything, your software will pull in personal transactions alongside business ones. You need to mark personal items as non-business so they are excluded from your quarterly updates. A separate business bank account makes this significantly easier.
Choosing the wrong expense categories
HMRC has specific expense categories, and putting expenses in the wrong category can cause problems. A business phone bill goes under administrative costs, not premises costs. Materials for a job go under cost of goods sold, not other expenses. Good software with AI categorisation reduces this risk by suggesting the correct category automatically.
Not understanding cumulative submissions
Each quarterly submission to HMRC is cumulative. Your Q2 update includes all income and expenses from Q1 and Q2 combined, not just Q2 on its own. Your software handles this automatically, but understanding it helps you check that the figures look right.
Filing at the last minute
Each quarterly update has a deadline roughly one month after the quarter ends. Leaving it until the final day means no buffer if something goes wrong (a software issue, a bank feed delay, or simply getting busy). File in the first week after the quarter ends and forget about it.
Ignoring it and hoping it goes away
MTD is law. Ignoring it means HMRC penalty points accumulating silently until they turn into fines. Four missed deadlines and you are paying £200 per late submission. The earlier you start, the less stressful it is.
Sole Trader Expenses: What You Can and Cannot Claim
Understanding allowable expenses is not new to MTD. The rules are the same as under Self Assessment. But because you are now categorising and reporting expenses four times a year instead of once, it pays to be clear on what qualifies.
| Counts as Self-Employment Income | Does NOT Count |
|---|---|
| Payments from clients and customers | Employment income (PAYE salary) |
| Cash payments for services | Savings interest |
| Commission and fees earned | Dividend income from shares |
| Tips and gratuities | Pension income |
| Ad-hoc or one-off freelance work | Rental income (reported separately) |
| Sale of goods you produce or trade | Capital gains from selling assets |
What you can claim
Travel costs: Fuel, train tickets, bus fares, parking, tolls, and congestion charges for business journeys. You can claim actual costs or use HMRC's simplified mileage rate (45p per mile for the first 10,000 miles, then 25p per mile).
Office and administrative costs: Phone bills, internet, stationery, postage, software subscriptions, and computer equipment under £1,000.
Stock and materials: Raw materials, stock for resale, and consumables directly related to your work. A plumber's copper pipe. An electrician's wiring. A caterer's ingredients.
Professional fees: Accountant fees, legal costs, professional indemnity insurance, trade body memberships.
Advertising and marketing: Website hosting, business cards, online ads, and promotional materials.
Home office costs: If you work from home, you can claim a proportion of your household costs (heating, electricity, council tax, mortgage interest or rent) based on the space and time used for business. Alternatively, use HMRC's flat rate (£6 per week with no receipts needed, or more with evidence).
Clothing: Only specialist workwear or uniforms. A plumber's overalls qualify. A consultant's suit does not, even if you only wear it for work.
Training: Courses and qualifications that maintain or update existing skills. A qualified electrician doing a refresher course qualifies. A plumber training to become an electrician does not, as that is a new skill.
What you cannot claim
- Personal expenses (groceries, personal clothing, entertainment)
- Fines and penalties (parking tickets, HMRC fines)
- Client entertainment (meals with clients are not deductible)
- The cost of buying or improving your home (even if you work from it)
- Capital items over £1,000 without using capital allowances
Capital allowances
Larger purchases (vehicles, expensive equipment, machinery) are handled through capital allowances rather than being claimed as straightforward expenses. The Annual Investment Allowance lets you deduct the full cost of qualifying items up to £1,000,000 per year. Your MTD software or accountant can help you handle these correctly.

How MTD Affects Sole Traders Who Also Have a Job
Many sole traders also have PAYE employment. You might work full-time and run a side business, or work part-time while building your self-employment income. MTD applies to your self-employment income specifically, but the threshold calculation includes all qualifying income.
How the threshold works
If your combined self-employment and property income exceeds the threshold, you must comply with MTD for that income. Your employment income (which is handled through PAYE) is not included in the threshold calculation but is included in your Final Declaration.
For example: you earn £35,000 from your employed job and £22,000 from freelance work. Your self-employment income of £22,000 is below the £30,000 threshold for April 2027, so MTD would not apply until the £20,000 threshold kicks in (April 2028).
But if your freelance income is £32,000 and you also earn £5,000 in rental income, your combined qualifying income is £37,000, putting you in the April 2027 group.
What you file under MTD
Your quarterly updates only cover your self-employment and property income. Your PAYE employment income is reported separately by your employer. However, your Final Declaration at year-end brings everything together to calculate your total tax liability.
Tax codes and payments on account
If you are both employed and self-employed, your tax situation is more complex. HMRC may adjust your PAYE tax code to collect some self-employment tax through your salary, or you may need to make payments on account. MTD does not change this, but quarterly filing gives you a clearer picture of what you owe throughout the year.
Choosing MTD Software as a Sole Trader
The Making Tax Digital software market is crowded, but for sole traders the choice is simpler than it looks. Ask yourself three questions:
Do I need invoicing?
If you invoice clients regularly, you need a tool that handles invoicing alongside MTD filing. Xero, QuickBooks, and FreeAgent all offer this. If you do not invoice (because customers pay you directly, or you use a separate invoicing tool) then invoicing in your MTD software is a feature you are paying for and not using.
Do I want to manage everything from my phone?
Most sole traders work on the go. A mobile-first tool lets you log expenses, scan receipts, and file quarterly updates from your phone. TapTax is designed this way. Full accounting platforms like Xero work best on desktop, with mobile apps that handle basic tasks.
What is my budget?
MTD software ranges from free to over £40 per month. For a sole trader who just needs MTD compliance, purpose-built tools start at £4.99 per month (TapTax Starter) and cover bank feeds, AI categorisation, receipt scanning, and one-tap filing. Full accounting platforms start at £12 per month and go up quickly. The best MTD software comparison breaks down exactly what you get at each price point.
Our recommendation
For most sole traders, a purpose-built MTD tool is the best fit. You get everything you need for quarterly filing without the complexity and cost of full accounting software. If your needs are simple (track income, track expenses, file to HMRC) you do not need to overcomplicate it.
What Happens Next
MTD for sole traders is happening. The April 2026 start date for the first cohort is weeks away, and the £30,000 and £20,000 thresholds follow in 2027 and 2028.
The transition does not need to be painful. Choose your software, connect your bank, spend a few minutes each week keeping your records tidy, and file when the deadline approaches. That is it.
The sole traders who will find MTD easiest are the ones who start now, before it is mandatory, before the deadline pressure, and before the last-minute rush. The ones who will struggle are the ones who leave it until the night before their first quarterly filing.
You know which group you want to be in.
