Making Tax Digital (MTD) for Income Tax represents a fundamental change to how sole traders and landlords in the UK report their income to HMRC. Instead of completing a single annual Self Assessment tax return, you'll be required to maintain digital records and submit quarterly summary updates throughout the year.
What Is Making Tax Digital for Income Tax?
MTD for Income Tax is HMRC's initiative to modernise the tax system by requiring digital record-keeping and more frequent reporting. The aim is to reduce errors, make tax administration more efficient, and help taxpayers keep on top of their obligations throughout the year rather than facing a once-yearly deadline.
Key Requirements Under MTD
If you fall within scope, you must comply with several new obligations:
- Digital record-keeping: All business income and expenses, plus rental income and costs, must be stored electronically using compatible software or spreadsheets.
- HMRC-approved software: You must use software that can connect to HMRC's systems to submit your updates. Many accounting packages already offer MTD-compatible features.
- Quarterly updates: Every three months, you'll send summary totals of your income and expenses to HMRC—not detailed transactions, but aggregated figures.
- Final declaration: At the end of the tax year, you'll submit a final statement confirming all figures, making any adjustments, and including other income sources such as employment or investment income.
Rollout Timeline by Income Threshold
MTD for Income Tax is being introduced in phases based on your combined gross income from self-employment and property:
- 6 April 2026: Mandatory for those with combined gross income over £50,000
- 6 April 2027: Extended to those with income over £30,000
- 6 April 2028: Further extended to those with income over £20,000
Your 'gross income' means your total business and rental income before deducting expenses. If your income fluctuates near these thresholds, check the current rules with your accountant as you approach each date.
Preparing for MTD
If you're affected by the initial rollout in April 2026, now is the time to prepare. Consider whether your current record-keeping systems are already digital, or whether you need to transition from paper records or manual spreadsheets. Investigate MTD-compatible software options—many providers offer packages tailored to sole traders and landlords at various price points.
You may also want to discuss your specific circumstances with an accountant. They can help you choose appropriate software, set up your digital records correctly, and ensure your quarterly submissions are accurate. Getting professional support during the transition can prevent costly mistakes and reduce the administrative burden.
What If Your Income Falls Below the Threshold?
If your gross income is below the relevant threshold for each phase, you can continue using the traditional Self Assessment process for now. However, HMRC may extend MTD to lower income levels in future years, so staying informed about changes is advisable.
Making Tax Digital for Income Tax is a significant change, but with proper preparation and the right tools, it can actually help you maintain better financial oversight of your business or rental activities throughout the year.
