How do I check or add CIS deductions in EasyTaxer?

CIS deductions taken by contractors count as advance payments towards your tax and National Insurance, and are set against your tax bill. HMRC adds the subcontractor deductions it holds to your tax return. On Income → CIS you see them, and can add a contractor's deductions once the tax year has ended.

The short answer

If you're a subcontractor under the Construction Industry Scheme, the deductions contractors take from your payments count as advance payments towards your tax and National Insurance. They're set against your tax bill. In EasyTaxer, that's Income, then CIS.
The deduction rates

A contractor deducts 20% if you're registered for CIS, and 30% if you're not. With gross payment status, nothing is deducted, and you pay your own tax.
What HMRC holds

HMRC adds the CIS subcontractor deductions it holds to your tax return, and you must check them. In EasyTaxer, Deductions held by HMRC shows a record for each contractor. Records reported by a contractor are read-only.
Adding a contractor's deductions

If one is missing, use Add a contractor's deductions: the contractor, their employer reference, the whole tax year from 6 April to 5 April, and the monthly figures. HMRC only accepts new records once the tax year has ended: for 2026 to 2027, after 5 April 2027.
