CISR61230 - Monthly returns: overview: CIS300 - familiarisation - CIS300(Notes) - page 5 & 6

The text of the notes contains useful information for contractors.

Pages 1, 2, 3 and 4 of the notes can be found in the information panels at CISR61190, CISR61200, CISR61210 and CISR61220. Pages 5 & 6 conclude with:

Materials paid for by the subcontractor. Enter the amount for the cost of any materials paid to the subcontractor in the month.

Total amount deducted on account of tax. Enter the amount you have deducted from the subcontractor in the month. If making a payment under deduction to a subcontractor for the first time, you must use the deduction rate we gave you.

If making a payment under deduction to a subcontractor you have paid previously, you must continue to use the same deduction rate as before unless we have told you of a change to that rate.

Example of how to calculate the deductions

Using an 20% rate

Example of 20% Deduction Amount
Total payments made £2, 567.00 (A)
Less cost of materials £367.00 (B)
Total amount deducted (A) – (B) £2,200 x 20% = £440.00
Example of 30% Deduction Amount
Total payments made £2, 567.00 (A)
Less cost of materials £367.00 (B)
Total amount deducted (A) – (B) £2,200 x 30% = £660.00

If a subcontractor’s tax treatment changes in the month and you have made payments under deduction of tax as well as gross payments, you should only make one entry for that subcontractor showing the total payments and deductions made.
