CIS refunds, fast and proper

Most CIS workers have been over-deducted. We file your Self Assessment, claim back the over-paid 20% (or 30%), and apply every legitimate expense — tools, mileage, PPE, training.

Real numbers

Average CIS refund: £600 – £1,800

Most sub-contractors over-pay because the 20% (or 30% unverified) deduction doesn't account for your expenses. We routinely recover £600–£1,800 per tax year, and many clients haven't filed for 3 years — so it's £1,800 to £5,000+ back in pocket.

Honest answers

You probably want to know

How fast do I get my refund?
We file in 24 hours. HMRC then takes 2–4 weeks to process the refund into your bank account. We monitor and chase if it's late.
I've been working CIS for 3 years and never filed. Trouble?
Probably the opposite — HMRC owe you. Multiple-year filings are common in CIS. We file all overdue years at once and claim back over-deductions for each. Late penalties are sometimes waived when you're owed money.
My contractor messed up my CIS deductions — can you fix that?
Yes. We reconcile your CIS300 monthly statements against your bank deposits and what your contractor reported to HMRC. Errors are common — we'll work directly with HMRC to fix them.
Can I claim my van?
Two options: use the simplified flat-rate mileage (45p/mile up to 10k miles) or claim actual costs (fuel, insurance, MOT, tax, repairs, capital allowance on the van itself). We'll model both and pick whichever saves you most.

Stop dreading tax. Start ignoring it.
