For kitchen & bathroom fitters

MTD for Income Tax for kitchen & bathroom fitters.

Big material orders passed to the client, deposits, other trades to coordinate and cash flow to manage. Here's how Making Tax Digital for Income Tax applies to fitters, and when it starts for you.

Does this apply to me?

Material pass-through pushes you over £50,000 fast.

MTD for Income Tax is measured on gross income before expenses. When you buy the units and appliances and recharge them, that turnover counts, so most fitters are well in scope.

Gross, not profit

A £12,000 kitchen is £12,000 of turnover.

Even if most of that is units and appliances you bought in, it all counts as gross income for the threshold. Recording the matching purchases as expenses is what keeps your tax based on the real margin.

The fitting detail

The bits specific to your trade.

Materials pass-through

Units and appliances you buy and recharge count as income. Record the purchases so you're taxed on the fitting margin.

Deposits and cash flow

Deposits fund the supply order. Recorded in the right quarter, they keep your figures and your cash flow clear.

Coordinating trades

Bringing in an electrician or plumber? Their invoice to you is an expense. Keep it clear so your turnover isn't overstated.

Showroom referrals

Work referred from a showroom is income like any other. Record it against the job with its own costs.

Common questions

Kitchen & bathroom fitter MTD FAQ.

Do kitchen and bathroom fitters have to use MTD for Income Tax?
Yes, if you're self-employed with gross income over £50,000, it applies from 6 April 2026. The threshold drops to £30,000 from April 2027 and £20,000 from April 2028.
Units and appliances pass through my invoices, does that count as income?
Yes. If you buy and recharge them, the full amount is your income and the purchases are your expenses. Because MTD tests gross income, the pass-through pushes you over the threshold faster than profit alone.
How do deposits work under quarterly reporting?
A deposit is income in the quarter you receive it, and materials are expenses in the quarter you buy them. Recording both keeps your profit accurate over the job.
I bring in other trades, how do I record that?
If you pay an electrician or plumber for your job, that's an expense. If they invoice the client directly, it isn't your income at all. Keeping this clear stops your turnover being overstated.
What else can I claim?
Typical costs include materials and appliances, tools, van and fuel, insurance, waste removal and payments to other trades.
