CIS Income & Deductions
Enter your gross income and the CIS tax deducted by your contractors. This is the core of your rebate calculation.
How CIS works: Your contractor pays you the gross amount minus 20% (or 30%) CIS tax deduction. You enter the full gross amount you were entitled to, and separately the total CIS deducted. The difference is what you actually received. Your rebate is calculated from these figures plus your expenses.

Number of Contractors
Allowable Expenses
Every expense you claim reduces your profit and increases your CIS rebate. Don’t leave money on the table — enter everything you’ve spent for work this quarter.
SmartTaxSense tip: Most CIS subbies underclaim expenses and leave hundreds of pounds of rebate unclaimed every year. Enter everything — tools, fuel, PPE, phone, even the work boots. Our AI will check you haven’t missed anything obvious.
