Your CIS Questions Answered
Can I claim back CIS tax?
If you're self-employed, the CIS deductions taken from your pay count towards your tax bill in your Self Assessment return. Many subcontractors have paid too much and are owed a refund.

20% if you're registered for CIS, 30% if you're not, and 0% if you have gross payment status.
When is the monthly CIS return due?
Contractors must file the CIS300 by the 19th of each month, covering the tax month that ends on the 5th.
How do I get gross payment status?
You have to pass HMRC's business, turnover and compliance tests. We check whether you qualify and apply for you.
