Making Tax Digital for Income Tax: What Scottish Sole Traders Need to Know

If you're a sole trader or landlord in Scotland, Making Tax Digital for Income Tax Self Assessment — known as MTD ITSA — will change how you report your income to HMRC. From April 2026 the first wave becomes mandatory, and the changes are significant enough that leaving preparation to the last minute is a genuine risk.

What Is MTD ITSA?

Currently, sole traders file one Self Assessment return each year by 31 January. Under MTD ITSA, that changes to a quarterly system. You'll need to maintain digital records throughout the year using HMRC-recognised software, submit a quarterly income and expenses update to HMRC four times a year, and submit a final end-of-year declaration to confirm your figures and claim any reliefs.

The amount of tax you owe doesn't automatically change — but the way you report it does. Spreadsheets, paper records and year-end scrambles will no longer be workable for those in scope.

Does MTD Apply Differently in Scotland?

MTD ITSA is a UK-wide HMRC scheme with the same deadlines in Scotland as in England. The key Scottish difference is at the year-end stage: when HMRC calculates your actual income tax liability, it uses Scottish income tax bands, which differ significantly from the rest of the UK. Scotland's higher rate of 42% kicks in at £43,663 — well below England's £50,271 — meaning many Scottish sole traders pay more in tax at lower income levels. Your accountant must apply Scottish rates correctly in the final declaration.

What Software Will You Need?

You must use HMRC-approved MTD-compatible software. Options include Xero, QuickBooks, FreeAgent and others. At Forever Accounting we're Xero-certified and handle all quarterly submissions on your behalf — you just need to keep your transactions up to date throughout the year. We integrate directly with your bank feed so the bookkeeping burden is minimal.

What Should You Do Right Now?

• Check your income threshold. If your combined self-employment and/or property income exceeds £50,000 in 2025/26, you're in the April 2026 group.
• Review your record-keeping. Paper receipts and year-end summaries won't work under MTD. Start tracking digitally now.
• Speak to an accountant. MTD ITSA is more manageable with professional support from day one. We handle registration, software setup and every quarterly submission as standard.

We're helping sole traders and landlords across Glasgow, Edinburgh and Scotland prepare for MTD as part of our standard sole trader accounting service. If you're approaching the threshold or want to understand what's coming, get in touch below.
