Does this apply to me?

If you turn over more than £50,000, it applies now.

MTD for Income Tax is measured on gross income before expenses. Timber and materials for larger commissions push your gross turnover up faster than the profit alone.

The carpentry detail

The bits specific to your trade.

Commission deposits

A deposit is income when received. Record it against the job so the eventual balance and materials all line up.

Timber and materials

Sheet goods and hardwood are real costs. Logged against the job, they offset the income so you're taxed on the margin.

Machinery and tools

Big machines go through capital allowances; smaller tools are expensed. Keep both recorded and nothing is missed.

CIS on site

If you subcontract on construction sites, CIS may be deducted from your labour. It still counts towards your tax, reconciled through MTD.

Common questions

Carpenter & joiner MTD FAQ.

Do carpenters and joiners 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.
How do commission deposits work under quarterly reporting?
A deposit is income in the quarter you receive it. The timber and materials you buy are expenses in the quarter you buy them, so your profit reflects the real margin over the job.
Can I claim my workshop and machinery?
Yes. Workshop rent and running costs are deductible, and larger machinery is typically claimed through capital allowances. Clear Books lets you record both.
What else can I claim?
Typical costs include timber and materials, hand and power tools, consumables, your van and fuel, insurance and workwear.
I do CIS subcontract work too, does that change MTD?
No. CIS deducted from your on-site work still counts towards your tax bill. Under MTD you record the gross income and CIS deducted so it reconciles at year-end.
