If you work in the construction sector in the UK, it is important to understand how you can claim the maximum refund of tax paid. By being familiar with the Construction Industry Scheme (CIS), eligible expenses and the proper steps for filing documents, you can significantly increase the refund you receive from HM Revenue & Customs (HMRC, the UK tax authorities).
How does the Construction Industry Scheme (CIS) work?
The Construction Industry Scheme (CIS) is a UK government scheme that regulates payments between contractors and subcontractors in the construction sector. Its primary purpose is to ensure that taxes on income from construction activities are correctly withheld and paid to HMRC.
Key features of CIS:
- Who does it affect? All construction contractors and subcontractors, including self-employed individuals, companies and organisations that hire subcontractors for construction activities.
- Deduction rate: 20% for registered subcontractors and 30% for unregistered subcontractors. Registration allows subcontractors to pay lower tax deductions.
- Tax refunds: Subcontractors who have paid more tax than they owed can claim a refund when submitting their annual tax return.
- Contractors’ obligations: Contractors must withhold tax, keep detailed records of payments and submit monthly reports to HMRC.
The scheme is mandatory for companies paying for construction work, and failure to register can result in higher deductions and penalties.
More information can be found on the official government website.
Which expenses can be reclaimed?
HMRC allows certain expenses to be deducted from taxable income. This enables you to reduce the taxes owed and reclaim more money.
Examples of eligible expenses:
| Category | Description |
| Tools and equipment | Purchase, repair or replacement of work tools. |
| Transport | Mileage for personal vehicle use. |
| Travel and subsistence | Costs for accommodation and meals when working away from the main workplace. |
| Training and certificates | Health and safety courses, renewal of CSCS card. |
| Workwear | Purchase and maintenance of protective equipment. |
| Professional fees | Membership fees for unions or professional associations. |
Important! Always keep receipts and documentation of your expenses to avoid issues with HMRC.
How can you avoid mistakes when filing documents?
Errors in tax returns can lead to delays and loss of funds. To avoid these issues, here are some key tips:
- Register
- If you are self-employed, make sure that you register for Self Assessment with HMRC in a timely manner to avoid penalties.
- Ensure that you have the following documents prepared: P60, P11D (if employed), accounting records (if self-employed), information on savings and interest.
- Keep accurate records of all income, expenses and CIS deductions.
- Verify all entered data, including figures and reference codes.
- Submit your return on time – here are the deadlines for submitting a Self Assessment return in the UK:
- If submitting on paper, the deadline is 31 October of the following tax year.
- If submitting online, the deadline is 31 January of the following tax year.
- Use tax software like FreeAgent or Xero to help manage your finances.
Common mistakes to avoid:
- Not registering for CIS – if you work in the construction sector and are not registered, your deductions will be 30% instead of the standard 20%.
- Incorrect expenses – claiming expenses that are not allowable can lead to audits and penalties from HMRC.
- Missing deadlines – delays in filing can lead to fines and penalties.

Frequently asked questions

Typically, HMRC processes claims within four to six weeks after the return is submitted.
· If you submit a refund request online, HMRC usually sends the money within five working days.

2. Can I claim a refund without receipts?
- For certain expenses, such as mileage for business travel using a personal vehicle, receipts are not required, but HMRC may request supporting evidence, such as a mileage log.
- For most other expenses (tools, uniforms, professional fees), it is advisable to keep receipts or bank statements.
3. What should I do if I work for several contractors?
- If you are registered under the Construction Industry Scheme (CIS) and work for multiple contractors, all deductions made by them are consolidated in your annual Self Assessment tax return.
