CIS Scheme Help for Contractors & Self-Employed Subcontractors

CIS Returns for Contractors

If you’re a contractor, you must submit monthly CIS returns to HMRC detailing all payments to subcontractors. Our CIS tax return accountants handle everything for you – from verifying subcontractors to filing on time – so you avoid penalties and stay compliant.

CIS Returns for Subcontractors

Working as a subcontractor? You may be due a tax refund if too much tax has been deducted at source. We provide complete CIS tax return help, ensuring your self-employed CIS tax return is accurate, maximises expenses, and secures any CIS tax refund you’re owed.

CIS Self-Assessment Tax Returns

Subcontractors still need to file a CIS self assessment tax return each year. We’ll manage the whole process – recording income, claiming allowable expenses, and reconciling CIS deductions – so your tax return for CIS subcontractor status is stress-free.

Bookkeeping & Expense Management

Keeping accurate records is key for CIS tax returns. We’ll maintain your books, log allowable expenses such as tools, travel, and protective equipment, and make sure every claim reduces your tax liability.

CIS Tax Refunds

If you’ve overpaid tax, we’ll process your claim quickly and accurately, ensuring HMRC issues your refund without delays. With expert CIS tax return accountants on your side, you’ll always claim back what you’re entitled to.

More Than Just CIS Tax Returns

Whether you’re a contractor or subcontractor, we don’t just file CIS returns – we help you plan ahead, manage cash flow, and keep your tax affairs simple. From monthly filings to annual self assessment, our CIS tax return help gives you complete peace of mind.

Benefits of outsourcing your CIS Returns to Accounting Wise

Some of the benefits of using Accounting Wise to handle your tax affairs are:

Peace of mind
By using professionals you know that your CIS tax return will be correct and accurate.

CIS Investigations
You are less likely to be investigated by HMRC if you use an adviser, as HMRC have ways of knowing if figures submitted on a CIS return are likely to be incorrect. This is a common trigger for a tax investigation.

Save time
In most cases it will take you a lot longer to complete your own CIS return than it would for an adviser. This time could be better spent running your business.

Essential Construction Industry Scheme FAQ

0330 113 8442 Request Call Back

A CIS return is a monthly tax report that contractors must submit to HMRC, detailing payments made to subcontractors and any deductions for tax purposes.

Contractors registered under the Construction Industry Scheme (CIS) must submit CIS returns. Subcontractors may also need to file a CIS tax return to claim deductions or request a CIS tax refund.

CIS returns must be submitted to HMRC by the 19th of each month, covering payments made to subcontractors in the previous tax month.

Late CIS returns can result in HMRC penalties, which increase the longer the return remains unfiled. It’s essential to submit on time to avoid unnecessary fines.

Yes, if too much tax has been deducted under the CIS scheme, subcontractors can claim a CIS tax refund at the end of the tax year by filing a self-assessment tax return.

Contractors and subcontractors can register for CIS through HMRC. Registering ensures the correct tax deductions are applied to payments.

The standard CIS deduction rate is 20% for registered subcontractors and 30% for unregistered ones. Gross payment status allows subcontractors to receive full payments with no deductions.

Yes, limited companies operating as contractors must file CIS returns for any subcontractor payments made under the scheme. They may also be eligible for CIS tax refunds if overpayments occur.

CIS returns require details of payments made to subcontractors, deductions applied, verification numbers, and any direct costs incurred.

Absolutely! Our expert CIS accountants will manage your CIS tax return, ensuring timely submission, compliance with HMRC, and maximising any potential CIS tax refunds. Request a callback today!

What is CIS?

What is the Construction Industry Scheme (CIS)?

CIS applies to most workers in the construction industry. If you are a contractor you will need to deduct CIS tax from your subcontractors and submit CIS Returns to HMRC. If you are a subcontractor you will need to complete a tax return and claim your CIS refund.

CIS For Contractors

If you are a contractor within the construction industry then you will have to submit a CIS Return before the 19th of each month. A CIS tax return lets HMRC know how much CIS tax you have deducted from your sub-contractors and therefore how much you owe to them.

Unfortunately the penalties for late submissions are high. If it is one day late the penalty is £100 and if it is more than 2 months late a further £200 is payable with further penalties the longer it remains un-submitted. This is why it is very important that you put in place arrangements either yourself or for a professional to complete your CIS Returns on your behalf.

CIS For Subcontractors

If you are a sub-contractor in the construction industry you are required to complete a personal tax return each year. The tax return tells HMRC how much you have earned, how much expenditure you have incurred and how much CIS tax you have already paid.

As a sub-contractor it is likely you are entitled to a tax refund each year as you will have paid more in CIS tax than you owe to HMRC.
