Working as a CIS subcontractor in the UK construction industry comes with its own set of rules, especially when it comes to taxes. Whether you’re new to the Construction Industry Scheme (CIS) or have been subcontracting for years, this guide will help you understand what’s required to file your tax return and how you can maximize your tax refund. Let’s break down everything you need to know, step by step.
What Is the CIS (Construction Industry Scheme)?
The Construction Industry Scheme (CIS) is a tax scheme in the UK set up by HMRC specifically for individuals and businesses working in construction. The goal is to ensure tax compliance among subcontractors, who are often self-employed.
Under CIS:
- Contractors deduct 20% tax (or 30% if you’re not registered with HMRC) from your payments.
- These deductions go towards your income tax and National Insurance contributions.
While this might sound like a hassle, CIS deductions can actually work to your advantage if managed properly. Many subcontractors end up getting a tax refund at the end of the tax year.
Who Needs to Register as a CIS Subcontractor?
If you work in construction as a subcontractor, you’ll need to register for the CIS scheme. This applies if you:
- Are self-employed and provide construction services to a contractor.
- Work in construction areas like repairs, demolition, groundwork, painting, or even site preparation.
- Are a sole trader, part of a partnership, or operate through a limited company.
However, if you only supply materials, design work, or equipment (without labour), you might not need to register.
Why Do CIS Subcontractors Need to File a Tax Return?
Even if tax is already being deducted from your payments, as a subcontractor, you still need to file a Self Assessment tax return. Here’s why:
- To Report All Your Income: CIS deductions only cover payments made by contractors. If you have other income sources, like private jobs, they need to be declared.
- To Claim Business Expenses: As a subcontractor, you’re entitled to claim various expenses related to your work. This can reduce your taxable income and potentially result in a tax refund.
- To Get a Tax Refund: Often, the 20% tax deducted is more than you actually owe, especially if you have business expenses to deduct. Filing a tax return ensures you get back what you’re owed.
Step-by-Step Guide to Filing Your CIS Tax Return
If you’re a CIS subcontractor, filing your tax return might seem daunting, but it doesn’t have to be. Here’s a step-by-step guide to help you get it done:
- Register for Self Assessment with HMRC: If it’s your first time, you’ll need to register online to get a Unique Taxpayer Reference (UTR) number.
- Keep Accurate Records: Throughout the year, keep track of:
- Your CIS statements (contractors should provide these monthly).
- Receipts for expenses like tools, fuel, travel, and protective gear.
- Any additional income not covered by CIS deductions.
- Gather Your Paperwork: Before filing, gather:
- Your UTR number, National Insurance number, and CIS statements.
- Invoices, receipts, and bank statements showing your business expenses.
- Complete the Self Assessment Form (SA100): Include your total income, CIS deductions, and expenses.
- Claim Your Refund: If your CIS deductions exceed what you owe, HMRC will issue a tax refund directly to your bank account.
What Expenses Can CIS Subcontractors Claim?
One of the biggest benefits of filing a tax return is the ability to deduct business expenses, which can reduce your tax bill. Here are some common expenses you can claim:
- Tools and Equipment: Hammers, drills, protective gear, and any other tools necessary for your job.
- Travel Costs: Fuel, parking, public transport costs if you travel between job sites (excluding commuting from home to a fixed place of work).
- Subsistence: Meals and accommodation if you’re working away from home.
- Training and Certifications: Any courses or qualifications necessary for your work.
- Accountant Fees: The cost of hiring an accountant to handle your tax return.
Make sure you keep all receipts and records. HMRC may ask for proof if they decide to review your tax return.
How Much Tax Will You Pay as a CIS Subcontractor?
The amount of tax you pay depends on whether you’re registered with CIS:
- If registered: 20% of your payments will be deducted by the contractor.
- If not registered: 30% will be deducted.
Tip: Always register with CIS to avoid the higher 30% deduction rate. If you’re owed a refund, you’ll get it back when you file your tax return.
How to Maximize Your CIS Tax Refund
To get the most out of your tax return, consider the following:
- Track Every Expense: The more expenses you can claim, the less taxable income you’ll have. Use accounting software or even just a simple spreadsheet to stay organized.
- Claim Mileage: If you’re using your personal vehicle for work, you can claim mileage at 45p per mile for the first 10,000 miles, then 25p per mile after that.
- Use an Accountant: Navigating the tax system can be tricky. A professional accountant can help ensure you’re claiming everything you’re entitled to and can often find deductions you might have missed.
What Happens If You Don’t File Your Tax Return?
Failing to file your tax return on time can result in penalties. Here’s what you could face:
- Late Filing Penalty: £100 if your return is up to 3 months late.
- Additional Penalties: The longer you delay, the more penalties you’ll accrue. After 6 months, it can reach 5% of the tax due.
- Interest on Unpaid Taxes: HMRC will also charge interest on any unpaid tax, which can quickly add up.
The Self Assessment tax return deadline is January 31st each year.
