How does the CIS Tax Rebate work?

Total the gross payments made to you by contractors.

Check the amount of CIS tax already deducted (usually 20%).

Calculate your actual tax liability based on your annual profit after expenses.

The rebate is the difference between the tax already paid and your actual liability.

Calculated instantly with up-to-date HMRC thresholds. Our engine ensures 100% accuracy for the current tax year.

Pro Tip: Keep your receipts!

Registered Status: Being registered for CIS ensures you are taxed at 20% rather than 30%.

Construction Specific: This scheme applies specifically to subcontractors in the UK construction industry.

Refund Processing: Rebates are typically claimed after the end of the tax year via a tax return.
