How Do I Claim My CIS Refund?

Step 1: Check If You’re Eligible

To claim a CIS refund, you must have had tax deducted under the CIS as a subcontractor. The scheme applies to individuals, sole traders, partnerships, and limited companies working in the construction industry.

If you’ve overpaid tax, you can claim a refund if:

1. You are registered with the CIS – This helps reduce the rate of deductions from 30% to 20%.
2. You’ve accurately reported your income and expenses – This ensures your tax calculations reflect the actual deductions.

Step 2: Gather the Necessary Information

Before you claim, you’ll need specific details. For individuals and sole traders, gather:

• Your Unique Taxpayer Reference (UTR).
• Details of the payments and deductions made to you by contractors (these are shown on your payment and deduction statements provided by contractors).
• Your bank account details to receive the refund.

For limited companies, you will also need:

• Your company’s PAYE reference number.
• Your company’s name, address, and contact number.

Step 3: File Your Tax Return

Claiming a refund is done as part of your self-assessment tax return or your company’s end-of-year tax calculations.

For Individuals and Sole Traders

1. Complete your self-assessment tax return by the deadline (usually 31 January following the end of the tax year).
2. Include details of all your income, expenses, and the CIS deductions.
3. HMRC will calculate your tax bill. If the deductions you’ve already paid are higher than your tax liability, HMRC will refund the difference.

For Limited Companies

1. Use your PAYE system to offset the CIS deductions against your corporation tax, PAYE, and National Insurance liabilities.
2. If the deductions are higher than your liabilities, you can claim a refund by contacting HMRC directly.

Step 4: Submit Your Claim

For Individuals and Sole Traders

Once you’ve submitted your tax return, HMRC will automatically process any refund you are entitled to. There’s no need to send a separate request unless additional issues arise.

For Limited Companies

If you believe your company is due a refund, you can make a direct claim to HMRC. Write to HMRC with the following details:

• Your company name and contact details.
• Your PAYE reference number.
• Your company’s UTR.
• A breakdown of your CIS deductions.

Send your claim to:

Alternatively, you can contact HMRC through their online services or phone them for assistance.

Step 5: Ensure Accurate Records

To avoid delays in receiving your refund, it’s essential to keep accurate and organised records. Ensure you have:

1. Payment and deduction statements from your contractors.
2. Records of your income and business expenses.
3. Copies of your tax returns and correspondence with HMRC.

Good record-keeping helps HMRC process your claim faster and ensures you claim the correct amount.

Step 6: Check the Timeframe for Refunds

The time it takes to receive a CIS refund depends on several factors, including how soon you file your tax return and the accuracy of your submission. Generally:

• For individuals and sole traders, refunds are processed within 4-6 weeks of submitting your self-assessment.
• For limited companies, processing may take longer, especially if there are complexities with PAYE or corporation tax offsets.

Common Issues and How to Avoid Them

Delays in Refunds

Delays often happen due to incomplete or incorrect information in your tax return. Double-check all your details before submitting them to HMRC.

Missing Payment and Deduction Statements

If you don’t have your payment and deduction statements, contact your contractor immediately. HMRC will not process your claim without this documentation.

Incorrect Registration with CIS

Ensure you are registered with the scheme to benefit from reduced deductions. If you’re not registered, contractors will deduct 30% instead of 20%, leading to higher upfront costs.
