Making Tax Digital: a guide for UK glaziers

MTD for VAT already covers every VAT-registered glazier, and MTD for Income Tax started for sole traders in April 2026. Here is who is in, when, and where your job software fits.

General guidance, not legal or tax advice. Last checked: October 2026.

MTD for VAT

Since April 2022, every VAT-registered business — whatever its turnover — has had to keep VAT records digitally and file VAT returns through MTD-compatible software. For most glaziers that means accounting software such as Xero, fed by the invoices and bills the business raises.

MTD for Income Tax: sole traders and landlords

Making Tax Digital for Income Tax applies to sole traders and landlords according to their qualifying income — self-employment plus property income, before expenses:

Qualifying incomeMTD for Income Tax from
Over £50,0006 April 2026 (based on the 2024–25 tax return)
Over £30,0006 April 2027
Over £20,0006 April 2028

If you are in, you keep digital records and send HMRC quarterly updates through compatible software, then finalise the year. Limited companies are not in MTD for Income Tax. Check your own position with HMRC's eligibility checker or your accountant.

Where job software fits

The figures HMRC sees start life on your jobs: deposit invoices, final invoices, card payments, supplier bills for glass. The less re-typing between your job system and your accounts, the fewer errors at quarter end. The usual setup is a job system that raises the paperwork, connected to accounting software that holds the books and files with HMRC. Xero says it is recognised by HMRC for both MTD for VAT and MTD for Income Tax — HMRC now lists compatible software through its online finder.

Where Coglass fits

Coglass is not MTD filing software. It raises the paperwork and sends it to Xero, which files with HMRC:
