Hi,
Please see the below important information for the contractors to be aware of.
CIS on subcontractors from 6 April 2026:
As the rules currently stand, when contractors pay subcontractors within the construction industry scheme, 20% CIS tax should be deducted (30% for unregistered sub-contractors). A submission to HMRC must be made monthly for all CIS deducted. This applies to all subcontractors unless they have gross payment status. Materials being reimbursed alongside the CIS, must be paid to the subcontractor in full, but also reported to HMRC on your monthly CIS return.
From 6th April changes have been made by HMRC, to ensure contractors and subcontractors are complying with the above regulations.
-If a subcontractor is found to not have been paid correctly by having the relevant tax deducted from the labour cost, the contractor will face a penalty of 30% of the deduction which should have been made.
-If a contractor has not taken the appropriate action ensuring subcontractors have been paid correctly, they are at risk of the loss of their gross payment status for up to 5 years if they currently hold this.
-HMRC have also clamped down on the lack of filing monthly CIS returns. If a contractor fails to submit their CIS on time. Now you will receive a monthly fixed penalty of Β£100, a second late submission a fixed penalty will be charged at Β£200.
Then a tax-geared penalty at 6 months of a minimum of Β£300 or 5% of any liability which should have been shown on the return.
A further penalty at 12 months β the amount of this penalty will depend on why the return was late.
This means the responsibility as a contractor to ensure your subcontractors tax treatment is correct is essential. Before engaging with a new subcontractor, ensure that they are CIS registered and confirm the correct tax treatment before paying the subcontractor, so they will need verifying before any payment is made. This will ensure that submissions are made on time to avoid unnecessary fixed penalties.
Please do contact us if you have any queries with any of the above.
