CIS deductions: what expenses can you claim?

There are a ton of CIS deductions you can use to increase your rebate:

1. Car expenses (“mileage allowance”)

Use whichever calculation gets you a bigger refund:

A. you use your car for work 75% of the time? Then you can claim 75% of: fuel, car insurance, road tax, etc.

B. or you can just use HMRC’s simplified expense rate: 45p a mile up to 10,000 miles and 25p a mile beyond that.

2. Your own tools, materials, and safety equipment

Only thing to remember: you can only claim what is yours and bought for work.

Can be:

  • power tools, torches, drills, etc.
  • reflective vests, protective gloves, safety helmets, etc.
  • and also their cleaning and repair.

3. Meals on the site, travel to and from site

If your contract length is under 24 months, then you can claim:

  • meals at the contractor site that you pay for out of pocket: work lunchfood at the cafeteria
  • transport: bus ticket, tube ticket, etc.

4. Rent

Basically: if you use your spare room as a home office for 10% of the time, then you can deduct 10% of your rent and bills. Or — you can just claim a flat fee as your “home office allowance“.

What activities count as “office space”?

  • organising your receipts
  • writing invoices
  • doing your taxes
  • repairing and cleaning your tools, etc.

This only works for rent – you cannot claim mortgage payments!

5. Other things you probably don’t know you can claim

  • mobile phone bill – if you use your phone 50% of the time for work, you can claim 50% of the bill
  • Builders Liability Insurance premiums
  • accountancy fees (including our fee at TaxScouts).

What you need to do before you can claim something

Is it worth it?

If your expenses are under £1,000 per year, don’t bother with the receipts.

Just claim your £1,000 tax-free allowance instead.
