Making Tax Digital for Income Tax - What Glasgow Sole Traders Must Do Now

Making Tax Digital for Income Tax Self Assessment (MTD ITSA) is live for the first wave of affected taxpayers. If you are a sole trader or landlord with qualifying income above £50,000, you are required to comply from April 2026. This is one of the most significant changes to UK tax administration in decades.

For affected taxpayers, the change is not just a new filing date. It changes the rhythm of record-keeping. Income and expenses need to be captured digitally during the year, software needs to be ready for quarterly updates, and year-end adjustments still need attention. Waiting until the next January deadline to reconstruct a full year from statements and receipts becomes a much weaker working habit under a quarterly reporting system.

What Is MTD for Income Tax?

MTD ITSA replaces the annual self-assessment process for affected individuals with digital record-keeping, quarterly updates to HMRC, and a final year-end declaration.

• Four quarterly updates each year summarising income and expenses.

• One final declaration each year confirming totals and adjustments.

Quarterly updates are not a replacement for understanding the final tax position. They are regular summaries sent from the digital records. The year-end step remains important because accounts adjustments, reliefs, final checks, and personal tax information may still need to be considered before the position is complete.

Who Is Affected and When?

• April 2026: sole traders and landlords with qualifying income above £50,000.

• April 2027: the threshold extends to qualifying income above £30,000.

• April 2028: a further extension is anticipated, subject to HMRC confirmation.

Qualifying income includes self-employment turnover and gross rental income. If business and rental income together exceed the threshold, you may be in scope.

That distinction catches people out. The threshold is about qualifying income, not the profit left after expenses. A taxpayer with more than one relevant income stream needs to look at the combined picture. If you are close to a rollout threshold, reviewing the figures early gives you time to choose software, improve bookkeeping routines, and decide how much support you want each quarter.

What Records Must You Keep?

You must maintain digital records of business income and expenses throughout the year using MTD-compatible software. Spreadsheets alone are not enough unless they are connected to HMRC through an approved bridging solution. Xero, QuickBooks, and FreeAgent are all common MTD-compatible options.

Good digital records are more than a software subscription. Bank feeds need to be reconciled, invoices and receipts need to be captured with enough detail, private items need to be separated from business transactions, and property or self-employment records need to be organised consistently. If the source records are messy, quarterly reporting only exposes the mess more often.

How to Prepare Before Your Start Date

• Confirm whether your self-employment and rental income place you in scope.

• Choose software that fits the size and routine of your records.

• Move receipts, sales invoices, and bank transactions into a repeatable digital process.

• Decide who will review coding, reconcile accounts, and submit updates.

• Use the first quarters to identify missing information before year end.

What Are the Penalties for Non-Compliance?

HMRC is introducing a points-based penalty system for late submissions. Missing quarterly updates can build penalty points until a financial penalty is triggered. Late payment of tax continues to carry separate charges.

The practical risk is not only a penalty. Late or incomplete updates leave you with weaker information during the year and less time to correct records before the final declaration. A small backlog repeated across four quarters can become a much larger clean-up exercise, especially where bank transactions, cash sales, or mixed-use costs need explanation.

How Countify Can Help

• MTD readiness reviews to confirm whether and when you are in scope.

• Software setup on Xero, QuickBooks, or FreeAgent.

• Quarterly update preparation and submission.

• Year-end final declaration support.

• Ongoing monitoring as HMRC extends MTD to more taxpayers.

For Glasgow sole traders and landlords who already use cloud bookkeeping, preparation may be a matter of checking the workflow and permissions. For those still relying on paper, disconnected spreadsheets, or year-end reconstruction, the work is larger. Starting with a readiness review means the change can be planned in stages instead of rushed when the first update is due.

A quarterly routine can also improve decision-making. When records are reviewed regularly, you have a better view of sales, costs, cash set aside for tax, and information still missing from the file. That does not remove the need for year-end advice, but it gives both client and accountant cleaner material to work with.

Good preparation makes the first submission feel planned rather than experimental.
