Making Tax Digital for UK carpet fitters: what changes from April 2026

TL;DR: Making Tax Digital for Income Tax affects sole traders and landlords in stages: qualifying income over GBP 50,000 from 6 April 2026, over GBP 30,000 from 6 April 2027, and over GBP 20,000 from 6 April 2028. For UK carpet fitters, the practical work is keeping digital records through the year and submitting quarterly updates from software, not rebuilding the accounts at the last minute.

Current HMRC rule: Each update is calculated by compatible software from digital records and covers cumulative category totals from the start of the tax year to the end of the update period - not only the previous three months. If record keeping and filing use different software, keep a permitted digital link between them; manual re-keying or clipboard transfer is not a digital link. HMRC will not apply penalty points for late quarterly updates in 2026/27, but the updates must still be sent before you submit your Self Assessment tax return using compatible software. Check HMRC digital-record guidance, quarterly-update guidance and HMRC's current MTD journey.

If you run a carpet fitter business as a sole trader, Making Tax Digital for Income Tax changes the rhythm of your admin. It does not change the underlying idea that you record income and expenses. It changes when those records need to be digital and how often summary figures are sent to HMRC.

For carpet fitters, the exact start date still depends on qualifying income, so HMRC's current guidance matters more than hearsay: Use Making Tax Digital for Income Tax. Check that official guidance or speak to your accountant before making decisions for your own business.

For carpet fitters, the change is not a new kind of tax. It is a new operating rhythm for records. Digital income and expense records need to be kept as the year goes, quarterly updates become part of the timetable, and you still submit a Self Assessment tax return using compatible software for the year.

That matters because materials can be bought before fitting, while deposit and balance timing can split. Those timings can make the records look uneven if they are only rebuilt months later. Current records make the pattern easier to explain.

Every business has its own record-keeping wrinkles. For carpet fitters, the common ones are:

• Materials can be bought before fitting. Carpet, underlay and accessories may be paid for before the customer pays the balance. Record the cost when paid.
• Deposit and balance timing can split. A customer may pay a deposit at booking and the balance after fitting. Keep both together.
• Supplier accounts may settle later. Trade account invoices may not match the fitting date. Save and match them back to the job.
• Property readiness affects income timing. Delayed access or unfinished rooms can move work between periods. Record why.

For a carpet fitter, those are normal commercial patterns rather than problems by themselves. The risk is letting them sit in memory until a quarterly update or year-end review forces you to rebuild the story from fragments.

For a carpet fitter, income may come from one-off jobs, repeat customers, deposits, add-ons and retained arrangements. Record each payment when it arrives and connect it back to the job, customer, booking, route or invoice that produced it.

Use the measure sheet, invoice or customer reference as the anchor for deposits, balances and late-settling income. Save receipts for carpet and underlay and gripper and door bars as soon as they arrive, so the cost side is not waiting on customer settlement before it is recorded. If cash is still part of your business, record it in the same week. Cash is not the issue; missing records are.

Most carpet fitters will need clear categories for:

• carpet and underlay
• gripper and door bars
• adhesives
• van costs
• fuel
• waste disposal

Keep those categories stable enough that carpet and underlay, gripper and door bars and adhesives land in the same place each month. A short, consistent list is more useful than a complicated one that changes whenever the paperwork gets busy.

The least painful MTD preparation is weekly, not annual. For carpet fitters, that means adapting the same admin habit you already need for the business:

• record each payment against the measure sheet or invoice it belongs to
• save receipts for carpet and underlay and gripper and door bars
• mark deposits, balances or delayed payments while the detail is current
• note any unusual week or quarter while the detail is still fresh
• move the week's income and expenses into the digital finance record

That weekly habit is not about doing a tax return every Friday. It is about making the quarterly update a summary of records you already hold from the way the carpet fitter business actually runs.

For carpet fitters, cloud bookkeeping software can be easier if you want bank feeds and direct submission. A spreadsheet plus bridging software can work for simpler carpet fitter businesses if it is maintained properly. An accountant-led route can also work, but your accountant still needs timely digital records from you.

For many carpet fitters, a spreadsheet is the bridge between informal records and full software. It works only if it is updated consistently. A spreadsheet abandoned until year-end is not a practical MTD plan.
