What Making Tax Digital Means for Sole Traders

Making Tax Digital for Income Tax Self Assessment is no longer a distant policy announcement. From April 2026, sole traders and landlords earning over £50,000 will be required to keep digital records and submit quarterly updates to HMRC. This is the single biggest change to how self-employed people report their income in decades, and it is closer than most people realise.

The core idea behind MTD is straightforward. Instead of filing one Self Assessment tax return per year, you will need to submit summary updates to HMRC every quarter using compatible software. These are not full tax returns — they are digital summaries of your income and expenses for that period. At the end of the tax year, you will still submit a final declaration, but the quarterly updates mean HMRC has a much more current picture of your tax position throughout the year.

For sole traders, this means your bookkeeping needs to be consistent and up to date. You cannot leave everything until January and expect to file twelve months of records in one go. The quarterly cadence forces a discipline that, honestly, most sole traders should have been following anyway. If you have been keeping a spreadsheet or a shoebox of receipts, that approach will no longer be sufficient.

The software requirement is worth understanding clearly. HMRC requires that you use software that can connect to their systems via their API. This is not optional. You cannot submit quarterly updates manually through the HMRC website. Your software needs to be MTD-compatible, which means it must be able to send and receive data from HMRC directly.

This is where many sole traders start to worry about cost. The good news is that you do not need expensive accounting software. Tools like Accounted have been built specifically for this — MTD-compliant bookkeeping designed for sole traders and landlords, without the complexity or cost of software designed for larger businesses.

What records do you need to keep? HMRC requires digital records of all business income and expenses, broken down by category. You need to record the date, amount, and category of each transaction. If you are a landlord, you need separate records for each property. If you have multiple trades, each one needs its own set of records.

The penalties for non-compliance are real but not draconian at launch. HMRC has indicated a soft landing period where penalties will be lighter. However, this should not encourage complacency. The systems need to be in place before April 2026, and the quarterly rhythm needs to become second nature.

One common misconception is that MTD changes how much tax you pay. It does not. MTD is about how you report, not what you owe. Your tax liability is calculated the same way. The difference is transparency and frequency of reporting.

Another concern is the quarterly deadlines themselves. These align with standard quarters — so updates are due by the 7th of August, November, February, and May for the standard tax year. Missing a deadline will eventually attract penalties under the new points-based system, where you accumulate points for each late submission before a financial penalty kicks in.

For sole traders who already use digital bookkeeping software, the transition should be relatively smooth. The main change is connecting your software to HMRC and ensuring your quarterly submissions are sent on time. For those still using manual methods, the transition requires more planning. Start now. Get your records into a digital format, choose compatible software, and practise the quarterly rhythm before it becomes mandatory.

The £50,000 threshold applies from April 2026. Those earning over £30,000 will be brought in from April 2027. There is no confirmed date for those below £30,000, but the direction of travel is clear — MTD will eventually apply to everyone.

If you are a sole trader earning above the threshold, the time to prepare is now. Choose your software, set up your digital records, and start submitting as if the deadline has already arrived. The businesses that treat this as an opportunity to improve their financial visibility — rather than just another compliance burden — will be the ones that benefit most.
