Immigrant construction workers: claim your full CIS refund. Learn which expenses to include, avoid mistakes & get expert help from Leader Accountancy.
Working in UK construction as an immigrant brings unique challenges – from language barriers to understanding complex tax systems. If you’re paid under the Construction Industry Scheme (CIS), you could be missing out on substantial tax refunds. Many immigrant workers overpay tax but don’t claim it back due to confusion about the process. This guide will help you understand CIS tax refunds, maximize your claims, and overcome common obstacles faced by foreign construction workers in the UK.

Understanding CIS Deductions for Immigrant Workers
The Construction Industry Scheme (CIS) is a tax deduction system specifically for the UK construction industry. Under this scheme, contractors deduct tax directly from payments to subcontractors before paying them. This system often results in overpaid tax, especially for immigrant workers who may not be fully aware of their tax rights.
How CIS Tax Deductions Work
When you work as a subcontractor in construction, your payments are subject to automatic deductions:
- 20% deduction if you’re registered with HMRC under the CIS scheme
- 30% deduction if you’re not registered with HMRC
- 0% deduction if you have “gross payment status” (rare for new immigrant workers)
For immigrant construction workers, these deductions can be particularly confusing, especially when you’re new to the UK tax system. Many don’t realize these deductions are often higher than the actual tax they owe, meaning they’re entitled to claim money back.

Allowable Expenses for CIS Subcontractors
One of the biggest reasons immigrant construction workers overpay tax is not claiming all eligible expenses. As a self-employed construction worker in the UK, you can deduct many work-related costs before calculating your tax.

Common Expenses You Can Claim
Tools and Equipment
- Power tools and hand tools
- Specialist equipment
- Safety gear and workwear
- Tool repairs and maintenance
Travel and Vehicle Costs
- Fuel for travel between work sites
- Vehicle insurance for work purposes
- Public transport to work locations
- Temporary accommodation near sites
Training and Certifications
- Construction skills courses
- Health and safety certifications
- Professional memberships
- Technical training materials
Administrative Costs
- Phone bills for work calls
- Accountancy fees
- Work-related insurance
- Bank charges for business accounts
“Many immigrant workers miss out on claiming for tools, travel between sites, and protective clothing – these alone can reduce your tax bill by hundreds of pounds each year.”

Record-Keeping Tips for Immigrant Workers
Proper documentation is crucial for successful CIS tax refund claims. Keep these records organized:
- All receipts for work-related purchases (take photos with your phone)
- CIS payment and deduction statements from contractors
- Mileage log if using your vehicle between sites
- Bank statements showing work-related expenses
Pro Tip: Create a simple folder system in your native language to organize receipts by category (tools, travel, training, etc.). This makes it much easier when it’s time to claim your CIS tax refund.
CIS Tax Refund Process for Immigrant Workers
Claiming your CIS tax refund UK involves several steps. For immigrant workers unfamiliar with the UK tax system, this process can seem daunting, but broken down into simple steps, it becomes manageable.
Step-by-Step Guide to Claiming Your Refund
- Register for Self Assessment – If you haven’t already, register with HMRC as self-employed.
- Gather Documentation – Collect all CIS statements, receipts, and proof of expenses.
- Complete Your Tax Return – File a Self Assessment tax return, including all CIS deductions and expenses.
- Submit Before the Deadline – Ensure your return is submitted by January 31st following the tax year end.
- Receive Your Refund – HMRC typically processes refunds within 2-8 weeks after submission.
When Can You Claim?
You can claim your CIS tax refund after the tax year ends on April 5th. For example, for work done between April 6, 2024, and April 5, 2025, you can claim your refund after April 5, 2025. Most immigrant workers prefer to claim as soon as possible after the tax year ends to receive their money back quickly.

Frequently Asked Questions About CIS Tax Refunds

How much tax can CIS workers reclaim in the UK?
The amount varies significantly based on your income, expenses, and personal circumstances. On average, immigrant construction workers claim between £1,500 and £3,000 per tax year. Those with higher expenses or who work irregularly throughout the year often receive larger refunds. Some of our clients have received over £5,000 for a single tax year when all eligible expenses were properly claimed.
What documents do I need for a CIS refund?
You’ll need:
- CIS payment and deduction statements from all contractors you worked for
- Your Unique Taxpayer Reference (UTR) number
- National Insurance number
- Receipts and proof of all work-related expenses
- Bank statements showing income and expenses
- Photo ID and proof of address
If you’re missing some documents, don’t worry – Leader Accountancy can help you obtain replacements or work with alternative evidence.
How long does a CIS refund take?
After submitting your tax return, HMRC typically processes CIS refunds within 2-8 weeks. However, first-time claimants or those with complex situations may wait longer. When you work with Leader Accountancy, we expedite the process by ensuring all documentation is correct the first time, often reducing wait times to 3-4 weeks. We also provide tracking updates so you know exactly when to expect your refund.
Can I claim expenses if I’m paid through CIS?
Yes, absolutely. As a CIS subcontractor, you’re considered self-employed, which means you can claim all legitimate business expenses. This includes tools, work clothing, travel between sites (but not commuting to your first site), training, phone costs for work calls, and even a portion of your home bills if you handle paperwork at home. Many immigrant workers don’t realize the full range of expenses they can claim, which is why professional guidance often results in significantly larger refunds.
