Guides: CIS and tax, in English

Written for the van, not the waiting room. Short paragraphs, straight answers, a table where it helps. One new guide a week.

What is CIS? The complete guide

The whole scheme, start to finish: who counts as contractor and subbie, the 20%/30%/gross rates, how the money moves each month, the materials rule, and how to get yours back. Start here.

CIS refunds: how to get back what HMRC's been holding

Why most subbies overpay, how the claim works for sole traders and ltd companies, going back up to four years — and why a once-a-year rebate service stopped being enough in April 2026.

Reverse charge VAT: who pays HMRC when builders bill builders

The two questions that decide whether VAT goes on your invoice, the exact wording HMRC wants, the cash-flow hit nobody mentions, and the flat rate scheme trap.

The most useful page isn't a guide: the CIS calculator shows what should be coming off your invoice — 20%, 30% or gross, materials split out, reverse charge handled.
