Your CIS responsibilities

Introduced in the 1970s, the Construction Industry Scheme, commonly known as CIS, was created by HMRC as a way to regulate tax payments within the construction industry. It ensures that subcontractors’ income tax is deducted by the contractors at source and correctly paid to HMRC.

As a contractor, you are at the very heart of the scheme. 

All contractors must register with CIS by law and you have several responsibilities. This includes ensuring all deductions are made correctly and payments are made promptly. If you fail to adhere to these responsibilities, you will face significant penalties which may put your business at serious risk.

The main CIS responsibilities for contractors include:

Registering for CIS

Verify subcontractors

Deduct and pay tax

Submit monthly CIS returns

Provide payment and deduction statements

Keep accurate records







Registering for CIS

If you hire any subcontractors for any work in the construction industry, it is mandatory to register with the Construction Industry Scheme. This can be done online on the HMRC website. This is the first step to legally operate within the scheme.

Contact Us

Verify subcontractors

Before any payments can be made, you must verify every subcontractor with HMRC.

This will determine their tax status which will fall into the following categories:

  • Registered subcontractors - subject to a 20% tax deduction

  • Unregistered subcontractors - subject to a 30% tax deduction

  • Gross payment subcontractors - no deduction is required as they manage their own tax affairs

You’ll receive a verification number from HMRC, which must be included in all monthly returns. Even if you do not take any deductions from a subcontractor (as they have gross payment status) they must still be verified.


Contact Us

Deduct and pay tax

Once subcontractors have been verified, you as a contractor are then responsible for deducting the appropriate tax from their payment. This tax must be paid directly to HMRC by the 22nd of each month if paying electronically or by the 19th if paying via post.

Contact Us

Submit monthly CIS returns

Each month you must also submit a monthly CIS return to HMRC which details the following:


  • Payments that have been made to subcontractors

  • Tax deductions that have been made

  • Verification details for every subcontractor


Failing to submit CIS returns on time or with errors will cause your company to be hit with penalties by HMRC. These penalties will increase the longer the delay persists.

Calculate the penalties if HMRC decides your subbies are employees

With HMRC carrying out tens of thousands of new investigations each month, there is a high risk of big fines and penalties if your contracts are not satisfactory, or you have not fully understood the ever changing complexities of CIS (Construction Industry Scheme).

We Guarantee

Protection from HMRC reclassifing your subbies as employees.

If HMRC were to reclassify just one self-employed subbie as an employee with an average weekly pay of £1,000, the liability would surpass £9,500 in a year.

For a group of 15 self-employed subbies, this liability would escalate to over £136,000. These staggering amounts exclude potential HMRC fines, unpaid interest charges, or legal costs associated with challenging HMRC.
