Claim a refund of Construction Industry Scheme deductions as a limited company

Get a refund of your Construction Industry Scheme (CIS) deductions if you're a subcontractor and you've had more taken than you need to pay in tax.

How CIS refunds work

If you’re a subcontractor, your Construction Industry Scheme (CIS) deductions are advance payments towards your company’s tax.

If the amount you’ve had deducted is higher than the amount your company needs to pay in tax, you need to make a claim.

After you claim, we’ll use your deductions to pay any overdue PAYE or Corporation Tax balances.

If there’s any money left over, you can:

  • get a refund
  • use it to pay VAT or upcoming Corporation Tax bills

Who can make a claim

You must:

When you can claim

You can claim for a tax year once it has ended. A tax year runs from 6 April to the following 5 April.

For the past 6 tax years, you can claim online or by post.

For earlier tax years, you must claim by post.

You need to have submitted all:

In some cases, you can claim a refund for the current tax year before it has ended. Read the section ‘Claiming for the current tax year’.

What you’ll need

Overpayment amount

You’ll need to tell us how much you overpaid in the tax year you’re claiming for. This is the total amount of CIS deductions taken, minus the total amount of tax paid using CIS deductions.

To work this out, use your:

  • monthly Payment and Deduction statements
  • FPS and EPS records
  • monthly CIS returns, if you’re also a contractor

If you’re not sure, give us an estimate.

Company details

You’ll need your:

  • company name, telephone number and address
  • PAYE reference number
  • Corporation Tax unique tax reference

Payment details

If you want us to pay the refund into a bank or building society account, tell us the:

  • bank or building society name
  • bank account number
  • sort code
  • account holder’s name

If you want us to pay an agent or nominated person, submit your claim with a completed form R38 or signed authority.

Evidence

We check if your information matches the information your contractor has given us. If it does not, we’ll ask you for copies of your:

  • Payment and Deduction statements
  • bank statements

If you know that the information does not match, you can include copies when you make your claim.

If you want to use your refund to pay another tax

To use your deductions to pay an upcoming Corporation Tax bill, tell us which accounting period you want to pay for.

To use your deductions to pay VAT, tell us:

  • your VAT registration number
  • how much VAT you want to pay

Claiming for the current tax year

You can only claim a refund for a tax year before it has ended, if either:

  • your business has stopped trading
  • you’ve had deductions taken after changing to gross payment status

Your claim must include copies of all Payment and Deduction statements and bank statements you’ve received this tax year.

Claim online

You need to use the sign in details linked to your Corporation Tax and PAYE accounts.

If you’re an agent, you need to use the details you use to sign in to your agent services account.

You can create an agent services account if you do not have one.
