Make sure you’re not paying more tax than you should
Under the Construction Industry Scheme, tax is deducted from your income before you’re paid. Because these deductions are based on your gross income rather than your actual profit, many subcontractors end up paying more tax than they need to throughout the year.
We’ll prepare your Self Assessment tax return accurately, review your allowable expenses and, where you’re due a refund, help you claim it as quickly as possible.
Our service includes:
- Self Assessment tax returns prepared and filed with HMRC
- CIS deductions recorded accurately
- Business expenses reviewed thoroughly
- Tax refunds claimed promptly where applicable
Understanding the Construction Industry Scheme (CIS)
Under CIS, contractors deduct tax before paying subcontractors.
These deductions are advance payments towards your annual tax bill rather than the final amount you’ll owe. Once your income and allowable expenses have been reviewed through your Self Assessment tax return, you may have additional tax to pay or be entitled to a refund.
Keep your records organised all year round
Accurate bookkeeping makes completing your tax return quicker, easier and far less stressful.
We’ll help you by:
- Tracking CIS deductions from contractor statements
- Reconciling contractor statements against payments received
- Recording business expenses throughout the year
- Keeping everything organised and ready for your annual tax return

Frequently asked questions
How much tax is deducted under CIS?
Registered subcontractors have 20% deducted, while unregistered subcontractors have 30% deducted. These deductions are advance payments towards your annual tax bill rather than the final amount you’ll owe.
Am I due a CIS tax refund?
Many CIS subcontractors are. Because deductions are taken before your allowable expenses are considered, it’s common for subcontractors to have paid more tax than they actually owe. We’ll review your figures and claim any refund you’re entitled to.
Do I still need to file a Self Assessment tax return?
Yes. CIS deductions don’t replace Self Assessment. You’ll still need to submit a tax return each year to declare your income, claim your allowable expenses and calculate whether you owe additional tax or are due a refund.
Think you might be due a CIS tax refund?
Whether you need help with your Self Assessment tax return, CIS bookkeeping or registering as a subcontractor, we’re here to make the process straightforward and stress-free.
