Making Tax Digital for Income Tax 2026: Complete Guide for Sole Traders Over £50k
If you're a sole trader or landlord with annual gross income over £50,000, Making Tax Digital (MTD) for Income Tax becomes mandatory from 6 April 2026. That's just over a month away.
HMRC has started sending notification letters to affected taxpayers. If you've received one — or you think you might be affected — this guide covers everything you need to do.
What Is MTD for Income Tax?
Making Tax Digital for Income Tax (MTD for ITSA) replaces the annual Self Assessment tax return with quarterly digital reporting. Instead of submitting one return per year, you'll:
- Use MTD-compatible software to keep digital records of income and expenses
- Submit quarterly updates to HMRC (four times per year)
- Submit a final declaration at the end of the tax year (replacing your Self Assessment return)
The idea is that HMRC gets a more real-time view of your tax position, and you get fewer surprises at year-end.
Who Must Comply from April 2026?
You're in scope if all of the following apply:
- You're a sole trader and/or landlord
- Your gross income (not profit) from self-employment and/or property exceeds £50,000 per year
- You're already required to file a Self Assessment tax return
Gross income means total turnover before expenses. So if your business turns over £55,000 but your profit is only £30,000, you're still caught.
What About Lower Earners?
| Income Threshold | MTD Start Date |
|---|---|
| Over £50,000 | 6 April 2026 ← You're here |
| £30,000 – £50,000 | 6 April 2027 |
| Under £30,000 | TBC (likely 2028+) |
If you earn between £30k and £50k, see our MTD 2027 guide for £30k-£50k freelancers.
The Quarterly Reporting Schedule
Your tax year runs 6 April to 5 April. Under MTD, you'll submit updates at the end of each quarter:
| Quarter | Period | Deadline |
|---|---|---|
| Q1 | 6 April – 5 July | 7 August |
| Q2 | 6 July – 5 October | 7 November |
| Q3 | 6 October – 5 January | 7 February |
| Q4 | 6 January – 5 April | 7 May |
| Final declaration | Full year | 31 January (following year) |
Your first quarterly update (for Q1 2026/27) will be due by 7 August 2026.
What Software Do You Need?
You must use HMRC-recognised MTD-compatible software. You cannot submit quarterly updates through the HMRC website — it has to be through approved software.
Popular MTD-Compatible Options
Free/Low Cost:
- HMRC's own MTD software — free but very basic
- Spreadsheets + bridging software — keep your existing spreadsheet, use bridging software to submit digitally
Paid (Most Popular):
- FreeAgent — from £14.50/month, popular with sole traders
- Xero — from £15/month, good for growing businesses
- QuickBooks — from £12/month, user-friendly
- Sage — from £12/month, established UK provider
💡 Tip: If you're a sole trader doing straightforward invoicing, FreeAgent or QuickBooks are the easiest to set up. If you're already using spreadsheets, look into bridging software.
What Records Must Be Digital?
Under MTD, you must keep digital records of:
- Income: Every sale, invoice, or payment received
- Expenses: Every business cost, with date, amount, and category
- Bank transactions: Ideally linked to your software via bank feeds
You don't need to digitise every receipt — but you do need a digital record of the transaction (date, amount, category, supplier).
💡 Tip: Start categorising expenses now if you aren't already. Most MTD software uses standard HMRC categories. Getting this right from day one saves hours at year-end.
Step-by-Step: How to Prepare Before April 2026
Step 1: Check If You're Affected
Log into your HMRC online account and check your Self Assessment records. Look at your gross income for 2024/25. If it's over £50,000 from self-employment and/or property, you're in scope.
Step 2: Sign Up for MTD
You need to sign up through HMRC's MTD service — it's not automatic. You can do this through your Government Gateway account or through your MTD software.
Important: Don't leave this until April. The sign-up process can take a few days to activate.
Step 3: Choose Your Software
Pick MTD-compatible software that suits your business. Most offer free trials. Key things to look for:
- Automatic bank feeds (saves manual entry)
- Invoice creation (if you invoice clients)
- Expense categorisation
- Quarterly submission built in
Step 4: Migrate Your Records
If you're switching from spreadsheets or paper records, you'll need to:
- Import your opening balances
- Set up your income and expense categories
- Connect your business bank account
- Enter any transactions from 6 April 2026 onwards
Step 5: Set Up Quarterly Reminders
Mark your calendar for Q1 submission: 7 August 2026. Set reminders 2 weeks before each quarterly deadline.
What Happens If You Don't Comply?
HMRC has confirmed a soft landing period for the first year (2026/27). During this period:
- You won't be penalised for late quarterly submissions
- You will still need to submit a final declaration on time
- Points-based penalties will apply from the second year onwards
The Points-Based Penalty System
From year two, each late submission earns you a penalty point. Once you hit 4 points, you'll receive a £200 penalty for each subsequent late submission.
| Offence | Penalty |
|---|---|
| Late quarterly submission | 1 penalty point |
| Hitting 4 points threshold | £200 per late submission |
| Late final declaration | Separate penalty regime |
| Late payment | Interest + potential surcharges |
Common Questions
Do I still need to file a Self Assessment return?
No — the final declaration under MTD replaces your Self Assessment return. You'll still have a January deadline, but you'll submit through your MTD software.
What about partnerships?
Partnerships are currently excluded from MTD for Income Tax in 2026. HMRC plans to bring them in later, but no date confirmed.
Can I use my accountant?
Yes. Your accountant can submit on your behalf using MTD software. Many are already set up. Ask yours whether they're MTD-ready.
What if my income drops below £50k?
If your income falls below the threshold, you may be able to opt out. But once signed up, HMRC generally expects you to continue until you formally leave.
What about VAT-registered sole traders?
If you're already using MTD for VAT, this is a separate obligation. You'll need to do both: MTD for VAT and MTD for Income Tax.
Costs to Budget For
| Item | Typical Cost |
|---|---|
| MTD software | £12–£30/month |
| Accountant setup help | £100–£300 one-off |
| Bridging software (if keeping spreadsheets) | £50–£150/year |
