CIS Deductions & Claiming Back: Unlocking Your Tax Refunds

For subcontractors working under the Construction Industry Scheme (CIS), managing and reclaiming CIS deductions is essential to maintaining healthy cash flow. Overpaid CIS can tie up much-needed funds, especially for limited company subcontractors, until you claim them back. Knowing how to allocate deductions correctly and use the appropriate processes—like the Employer Payment Summary (EPS) and I-Form—ensures your business stays compliant and financially secure.

At Nichols & Co., we specialise in simplifying CIS processes, helping subcontractors recover overpaid tax efficiently while adhering to HMRC regulations.

What Are CIS Deductions and Why Do They Matter?

Under the CIS, contractors deduct a percentage of a subcontractor’s earnings and send it to HMRC on their behalf. These deductions are typically 20% for registered subcontractors and 30% for those not registered. For subcontractors with gross payment status, no deductions are made, but they must declare all income on their Corporation Tax return.

If CIS deductions are made, they are treated as advance tax payments. However, many subcontractors, particularly limited companies, find that their deductions exceed their actual tax liability. To avoid tying up cash unnecessarily, it’s vital to reclaim overpaid deductions using the correct processes.

How to Claim Back CIS Deductions: The Correct Process

Claiming back CIS deductions for limited companies must be done via an Employer Payment Summary (EPS) submitted through your PAYE scheme. This process ensures that overpayments are correctly allocated and avoids penalties from HMRC for using an incorrect method, such as attempting to claim deductions via a Corporation Tax (CT600) return.

Steps to Claim CIS Deductions:

• 1. Submit an EPS Monthly: Use payroll software to send an EPS report to HMRC. This report must include Year-to-Date (YTD) figures for CIS deductions suffered.
  
• 2. Wait for HMRC to Update Your Account: HMRC uses these submissions to calculate your overpayments or liabilities.
  
• 3. Prepare and Submit the I-Form: Once your CIS deductions are updated in HMRC’s records, complete the I-Form to:
  
  • Request a refund of overpaid deductions.
  • Allocate overpayments against other taxes.

By following this process, you ensure compliance with HMRC rules while managing your cash flow effectively.

What Is Gross Payment Status, and Why Does It Matter?

If your company is registered for gross payment status, contractors do not deduct CIS from your payments. Instead, you are responsible for paying your tax liabilities in full when submitting your Corporation Tax return. While gross payment status can improve cash flow, you must ensure accurate reporting and timely payments to HMRC to maintain this status.

Gross payment status is particularly useful for companies managing large contracts, as it allows for greater control over your finances. However, if your business loses this status due to non-compliance, contractors will revert to deducting CIS at 20% or 30%.

Why You Should Avoid Claiming CIS Deductions on a CT600

Claiming CIS deductions through your Corporation Tax (CT600) return is not permitted and could result in penalties from HMRC. The correct process involves submitting an EPS via your PAYE scheme, as outlined above. This ensures that CIS deductions are correctly accounted for and processed against your PAYE liabilities.

Turning CIS Deductions into Cash Flow Opportunities

Managing CIS deductions proactively not only helps you avoid cash flow bottlenecks but also offers flexibility in how overpayments are handled. For example, using the I-Form to allocate deductions against other taxes, such as VAT or Corporation Tax, can help reduce immediate liabilities and improve your overall financial position.

At Nichols & Co., we guide subcontractors through the CIS process, ensuring deductions are reclaimed or allocated in a way that supports your business goals.

Common Pitfalls to Avoid

While the CIS reclaim process is straightforward, there are common mistakes that can delay your refund or cause compliance issues:

• Submitting Incomplete EPS Reports: Ensure your EPS submissions are accurate and include Year-to-Date figures.
  
• Mismatched Records: Verify contractor deduction statements against your own records to avoid discrepancies.
  
• Using the Wrong Method: Never attempt to claim deductions via a CT600. Always use your PAYE scheme to report and reclaim CIS deductions.

Partnering with a professional can help you navigate these challenges and streamline your CIS reclaim process.
