What is a CIS Tax Rebate?

In the UK’s Construction Industry Scheme (CIS), subcontractors often have tax deducted at rates of 20% or 30%, without the benefit of the personal tax-free allowance. This setup frequently leads to tax overpayment.

When you file your Self-Assessment Tax Return at the end of the year, your correct tax liability is recalculated, taking into account your income, expenses, and personal allowance. If you’ve overpaid, you may be eligible for a CIS Tax Refund.

Who can use this calculator?

Anyone working in the construction industry who has had CIS deductions can use this calculator to estimate their potential rebate. If you work in construction as a PAYE employee, please use this calculator instead.

How accurate is this calculator?

While we strive for accuracy, the calculator is intended as a guide only. For precise figures, it’s best to consult a tax professional.

What expenses can I claim?

You can typically claim expenses like tools, safety gear, and travel costs related to work. When you make a claim with us, our accountants will provide you with detailed guidance on what you can claim.

Do I need receipts to claim expenses?

In many cases, you’ll need receipts to claim expenses. However, there are some instances where you may be able to claim without them. Our calculator can help you determine if you qualify.

How do I apply for a CIS tax rebate?

To apply for a CIS Tax Rebate, begin by using our calculator to get an estimated amount of the rebate you may be eligible for. Once you have this estimate, the next step is usually to complete a Self Assessment tax return. This formalises your application and allows for an accurate calculation of any overpaid tax that you may be entitled to reclaim.

How soon will I receive my rebate?

The time it takes to receive a rebate can vary, but it usually takes between a few weeks to a few months after you’ve submitted your claim.

Is my information secure?

Absolutely, your privacy and security are our top priorities. Any information you enter is kept confidential.
