Making Tax Digital (MTD) Guide UK — What You Need to Know

Understand Making Tax Digital — who it affects, when it starts, what software you need, and how to prepare for HMRC's digital tax reporting requirements.

Making Tax Digital (MTD) is the biggest change to UK tax administration in decades. It replaces traditional annual tax returns with digital record-keeping and quarterly reporting — affecting millions of self-employed people and landlords. Here is what you need to know and how to prepare.

What Is Changing

Under MTD, instead of filing one annual Self Assessment return, you will:

  1. Keep digital records of income and expenses using compatible software
  2. Submit quarterly updates to HMRC (roughly every three months)
  3. Submit a final declaration at the end of the tax year to confirm your figures

This replaces the traditional paper-based or manual spreadsheet approach with a real-time digital connection between your records and HMRC.

Who Is Affected and When

MTD Timeline

Date Who Must Comply
Already live VAT-registered businesses (since April 2022)
April 2026 Self-employed and landlords with income over £50,000
April 2027 Self-employed and landlords with income over £30,000
TBC Those with income over £20,000 (date not yet set)

Income here means your total gross business or rental income — not profit. If your self-employment turnover is £55,000 but your profit is £35,000, you still fall within the April 2026 threshold.

Who Is Not Affected (Yet)

  • Employed individuals with no self-employment or rental income
  • Self-employed or landlords with income under the current threshold
  • Companies — corporation tax has a separate digital reporting system
  • Partners in partnerships — specific MTD dates for partnerships are being confirmed separately

What You Need to Do

1. Check If You Are In Scope

If your self-employment income, rental income, or combination of both exceeds the relevant threshold, you must comply from the respective date.

2. Choose Compatible Software

HMRC maintains a list of MTD-compatible software. Options include:

Software Monthly Cost Best For
FreeAgent From £12/month Sole traders, freelancers
QuickBooks From £10/month Small businesses
Xero From £14/month Growing businesses, accountants
Sage From £12/month Traditional businesses
HMRC’s free tools £0 Very simple affairs
Bridging software Varies Those wanting to keep spreadsheets

Bridging software allows you to continue keeping records in a spreadsheet and submit via a compatible “bridge” to HMRC. This is the minimum-change option for those comfortable with spreadsheets.

3. Set Up Digital Record-Keeping

Your software must maintain digital records of:

  • All business income (each transaction or summary per customer)
  • All business expenses (categorised and recorded)
  • Any adjustments (personal use, capital allowances, etc.)

If you currently keep paper receipts in a shoebox or track income in a basic spreadsheet, you will need to transition to a digital system.

4. Submit Quarterly Updates

Approximately every three months, your software submits a summary of your income and expenses to HMRC. The quarterly periods broadly follow:

Quarter Period
Q1 6 April – 5 July
Q2 6 July – 5 October
Q3 6 October – 5 January
Q4 6 January – 5 April

You will have approximately one month after each quarter end to submit. These are estimates, not final figures — you can adjust them later.

5. Year-End Finalisation

After the tax year ends, you submit a final declaration confirming your income, expenses, and any adjustments. This replaces the Self Assessment tax return for income within scope.

MTD for VAT (Already Live)

If you are VAT-registered, MTD for VAT has been mandatory since April 2022. You must:

  • Keep digital VAT records
  • Submit VAT returns through compatible software
  • Maintain digital links between your records and the submission

The same software typically handles both VAT and income tax submissions.

Costs of Making Tax Digital

Cost Typical Amount
Compatible software £0–£170/year
Accountant (if using one) May increase slightly
Time spent learning software Variable
Set-up and data migration 1–5 hours typically

The government acknowledges that MTD imposes additional costs on small businesses. However, their position is that better record-keeping and fewer errors will ultimately save time and reduce tax over/underpayments.

How to Prepare Now

Even if your threshold date is not immediate:

  1. Start using digital accounting software — the sooner you adopt it, the easier the transition
  2. Digitise your records — move from paper to digital receipts and transaction logging
  3. Talk to your accountant — they can advise on the best software for your situation
  4. Separate business and personal finances — a dedicated business bank account makes digital record-keeping much simpler
  5. Review your income — check whether you are above the threshold and when you need to comply
  6. Use the self-employment tax calculator to estimate your quarterly figures

Penalties for Non-Compliance

HMRC is implementing a points-based penalty system for MTD:

  • Each late quarterly submission earns a penalty point
  • After reaching a threshold of points (initially 4), a £200 penalty applies for each further late submission
  • Late payment penalties accrue as a percentage of the outstanding tax

The system replaces the old fixed-penalty approach and is designed to be more proportionate — occasional late submissions are tolerated, but a pattern of non-compliance is penalised.
