A complete CIS Returns service for both contractors and sub-contractors

Because working in the construction industry need not be more complex.

We file your returns along with all your other HMRC submissions and produce all CIS documentation

A CIS Return for both Contractors and Subcontractors is optional in all of Accounting Wise’s competitively priced packages

If you work in the construction industry, there’s a good chance you’ll need to register under HMRC’s Construction Industry Scheme (CIS). This ensures the correct tax and National Insurance payments are being made.

Our CIS service has been designed to streamline the whole process for contractors and subcontractors working in the construction industry. Just sign up, send us your information every month and we’ll take care of the rest.

Our CIS service covers:

  • CIS monthly filings
  • Yearly CIS reclaim management
  • CIS deduction statements
  • HMRC Subcontractor verification

Our expert CIS accountants will ensure you are paid correctly, with the right tax deductions to comply with HMRC’s regulations.

What is 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 Return


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 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.


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.

Benefits of using 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 return will be correct and accurate.


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.
