MTD Software for Gas Engineers (UK, 2026): Automatic Quarterly Tax Submissions

Gas Safe registration, parts, calibration — a gas engineer's costs are constant, and they all count against your tax bill.

From April 2026, Making Tax Digital for Income Tax requires self-employed people to keep digital records and send HMRC quarterly updates once gross income passes the threshold (£50,000 from 2026, £30,000 from 2027, £20,000 from 2028). For most full-time gas engineers, that means quarterly reporting is coming — and the smart way to handle it is automatically.

Your expenses, captured the moment you spend

A gas engineer's deductible costs typically include:

• boiler and appliance parts
• calibration and test equipment
• Gas Safe registration
• van running costs

Photograph the receipt and AI reads the supplier, date and amount, then files it under the correct HMRC category in seconds. No shoebox, no month-end sorting — and nothing claimable slips through.

Income without the data entry

If you quote and invoice jobs in Sleepless Tradesman, your income is already recorded. Mark an invoice paid and it flows straight into your accounting — no re-typing into a separate ledger. That is what makes quarterly figures effortless: the numbers are built from work you have already done.

CIS deductions, handled

Many gas engineers work under the Construction Industry Scheme, with tax deducted at source by contractors. Those deductions and your subcontractor payments are part of your tax picture — recorded alongside everything else so your quarterly figures and year-end position are right, without you keeping a separate tally.

Quarterly figures, ready on tap

Your cumulative quarterly totals are calculated for you in the categories HMRC requires, with the deadline on screen and a reminder before it lands. Review and submit, or export a clean summary for your accountant. See the full accounting features.
