Self Assessment Tax return

What is a rebate?

What is a CIS tax rebate?

  • When working as a subcontractor in the construction industry, you are taxed under the Construction Industry Scheme (CIS) at a rate of either 20% or 30%. As a subcontractor, you must submit a self-assessment at the end of the tax year. If the tax you paid under CIS throughout the year exceeds the amount you owe based on your self-assessment, you will receive a rebate for the difference.

How to maximise the CIS Rebate?

  • The CIS rebate can be maximised through the use of allowable expenses. The allowable expenses are used to reduce the profits on which your tax liability is calculated through the self-assessment, therefore increasing the difference between what you paid throughout the year and the actual tax liability.
