Record CIS deductions as a subcontractor

Log the CIS tax contractors deduct from your pay, let SimpleTaxFlow calculate the deduction for you, and keep a per-contractor year-to-date view.

Follow the sequence

Work through the steps in order and return to this guide whenever the next action is unclear.

Keep the records current

Capture and review information as it happens, rather than leaving the whole quarter until the end.

Review before you finish

Check the details and any supporting evidence before completing the task.

01

What this guide covers

If contractors deduct CIS from your payments, record those deductions so they count toward your tax position. The CIS drawer can calculate the deduction from your gross pay and materials at the standard 20% or higher 30% rate.

02

1. Open the CIS drawer in Filing

Go to Filing and open the CIS section. Deductions are grouped by contractor (their employer reference), matching the CIS statements contractors must give you.

2. Enter the payment and let the rate do the maths

Enter the gross amount and any materials, then pick your CIS rate — 20% standard, 30% higher, or gross payment status. The deduction is calculated for you as rate × (gross − materials). You can still type the figure manually: your contractor's CIS statement is always the authoritative number.

3. Check the year-to-date summary

The per-contractor summary shows gross pay, materials, and total deductions for the tax year, with an overall total. Reconcile it against your CIS statements before year-end.

4. Understand where it goes

Recorded deductions are submitted to HMRC as part of your CIS position and offset against the tax you owe at year-end. Keep your contractor statements as evidence.
