Do I need Making Tax Digital software if I am self-employed?

From 6 April 2026, sole traders and landlords with gross income over £50,000 must keep digital records and send HMRC four quarterly updates plus a year-end declaration using MTD-compatible software. The threshold drops to £30,000 from April 2027 and is proposed at £20,000 from April 2028.

Is there one tax and compliance app for every trade?

Yes. The tax and admin core is the same for every trade — MTD, Self Assessment, invoices and mileage — with a compliance certificate layer built for each trade, from CP12 for gas to EICR for electrical. From £29 per month.

How much does tax software for the self-employed cost?

£29 per month. 30-day free trial, no card to start. Mates, apprentices and labourers use it free.

Say the cert at the boiler.
It's written by the time you leave.

CP12, EICR, EIC or minor works, filled in on the phone at the job. The invoice off the same visit. The photos tied to the address. Dated the day you did it, and it stays that way.

Start freeNo card. 30 days. Then £29 a month.

You're covered.

Built by a Gas Safe and electrical engineer.

The app on a phone: a CP12 landlord gas safety record being filled in by voice, three fields of twenty done. — The write-up as it happens at the boiler: spoken in, field by field, twenty fields to a finished CP12. It works with no signal and sends itself when you get one.

What you walk away with

A finished certificate

The customer has it there and then. CP12, EICR, EIC, minor works.

The invoice, sent

Off the same screen, the same day. Paid faster because it went the day you did the work.

Your remarks, written up

Say what you found. It writes the observations up for you.

Photos that know the address

Tied to the job they belong to, not lost in your camera roll.

A record that holds

Dated the day you did it. No one can change it after — not even us.

You don't type it. You say it.

Stood at the boiler, gloves on, you talk and the certificate fills in — landlord, tenant, address, every appliance. Spoken, not thumbed in on a doorstep.

Time the meter. It tells you if it passes.

Gas rate worked out as you go, checked against the appliance rating. No sums on the back of the job sheet, no second-guessing on the doorstep.

No signal? It doesn't care.

Fills in fine in a cellar or a plant room with no bars. Saves on the phone, and sends itself the moment you're back on.

If a job's ever argued over

What you wrote on the day is still there, exactly as you left it. Dated then, not now. No one can go back and change it, and you can take the whole lot with you whenever you like.

What you're doing now

A pad and a shoebox

Cheap and yours, but it's the evening writing it all up, and a certificate the customer chases you for six months on.

This

The cert done at the job, by voice. The invoice off the same visit. The record kept and dated. The one thing you carry, not a business to run.

The big all-in-one platforms

Scheduling, a team, a CRM, a diary to fill. Worth it if you're growing a firm with staff to run. A lot to pay for and learn if you're one man doing the work.
