If you are self-employed in the UK with gross income over £50,000, Making Tax Digital for Income Tax starts on 6 April 2026. That deadline is weeks away. This guide is a practical, step-by-step checklist to get you ready — not a theoretical overview, but the specific actions you need to take now.
If your gross income is between £30,000 and £50,000, you have until April 2027 (Phase 2). If it is between £20,000 and £30,000, your deadline is April 2028 (Phase 3). Either way, preparing early gives you time to adjust your workflow before it becomes mandatory.
Step 1: Check If You Are in Phase 1
HMRC determines your threshold using the tax return whose filing deadline fell just before the start of the tax year. For Phase 1 (2026/27), this is your 2024/25 Self Assessment return (filing deadline 31 January 2026).
Add up your gross income from:
- Self-employment (total turnover, before expenses)
- Property income (total rental income, before expenses)
If the combined total exceeds £50,000, you are in Phase 1. Note: this is gross income, not profit. A freelancer with £55,000 turnover and £20,000 expenses (£35,000 profit) is still in Phase 1.
Step 2: Choose MTD-Compatible Software
You need software that can:
- Store digital records of your income and expenses
- Submit quarterly updates to HMRC via their API
- Submit your End of Period Statement and Final Declaration
Popular MTD-compatible options include Xero, QuickBooks, FreeAgent, Sage, GoSimpleTax, and others. Some offer free tiers — see our MTD software comparison for details.
If you currently use a spreadsheet, you can continue — but you will need bridging software to submit data to HMRC. Check that your chosen bridging tool is on HMRC’s official compatible software list.
Step 3: Sign Up with HMRC
HMRC will not automatically enrol you. You must sign up for MTD for Income Tax through your Government Gateway account. If your accountant handles your tax affairs, discuss who will complete the sign-up process.
Step 4: Set Up Digital Record Keeping
From 6 April 2026, every business transaction must be recorded digitally with the date, amount, and category. If you currently use paper receipts, a notebook, or unstructured files, now is the time to switch.
The fastest approach:
- Scan receipts as you go — use SparkReceipt’s AI receipt scanner to capture every receipt in seconds. The vendor, amount, date, and VAT are extracted automatically.
- Connect your email — automatically fetch email receipts from SaaS subscriptions, online purchases, and digital services.
- Categorise by HMRC expense category — SparkReceipt categorises expenses automatically, matching the categories you need for your Self Assessment.
- Sync to accounting software — send categorised expenses to QuickBooks Online or export for use with your MTD tool.
Step 5: Understand Quarterly Reporting
Under MTD, you submit cumulative year-to-date summaries every quarter. These are not detailed line-by-line submissions — they are totals showing your income and expenses so far for the year.
Your first quarterly deadline is 7 August 2026 (covering 6 April – 5 July 2026). This means you need about four months of digital records before your first submission.
Generating quarterly expense reports in SparkReceipt gives you a clear view of your spending that maps directly to your quarterly update.
Step 6: Review Your Allowable Expenses
MTD does not change which expenses are deductible — the same HMRC rules apply. Make sure you are claiming everything you are entitled to:
- Working from home expenses (flat rate or actual costs)
- Mileage allowance (45p/mile for first 10,000 miles)
- Office supplies, software subscriptions, phone bills
- Professional fees (accountant, legal)
- Insurance, bank charges, advertising
- Training and professional development
See our complete guide to self-employed expenses in the UK for the full list.
Step 7: Talk to Your Accountant
If you use an accountant, discuss:
- Who will submit quarterly updates — you or them?
- Which software they recommend or already use
- How to share records digitally (SparkReceipt offers free accountant access)
- Whether your workflow needs to change
What Happens If You Do Not Comply
MTD introduces a new points-based penalty system. Each missed quarterly deadline adds a point. At 4 points, a £200 penalty kicks in — plus £200 for every subsequent miss. Late payments incur percentage-based charges from day 16. Failing to keep digital records can cost £5-15 per day.
