What Is a CIC Corporation Tax Return (CT600)?

A Community Interest Company corporation tax return CT600 filing is the process of reporting your CIC's taxable profits to HMRC each accounting period. While many people assume Community Interest Companies are treated like charities, the reality is different. A CIC is liable to Corporation Tax on its profits in the same way as any ordinary limited company, unless specific reliefs apply.

In our experience preparing CIC accounts and tax returns for social enterprises across the UK, this is one of the most misunderstood areas. Getting your CIC corporation tax return right matters because late or incorrect CT600 filings trigger automatic HMRC penalties, even where no tax is ultimately due. Our specialist CIC accountants handle the whole process for you.

Quick Answers

Common CIC Corporation Tax Questions

Do Community Interest Companies pay Corporation Tax?

Yes. A Community Interest Company is liable to Corporation Tax on its profits, just like any ordinary limited company, because it does not receive the same tax exemptions as a registered charity.

Learn more in our do CICs pay Corporation Tax guide.

How do I file a CT600 for my CIC?

You file a CIC corporation tax return CT600 using HMRC-approved software or through an accountant. The return reports your taxable profits and must be submitted within 12 months of your accounting period end.

Our guide on HMRC corporation tax filing notices explains what to do if HMRC contacts you.

Can a CIC claim Gift Aid or charitable reliefs?

No. A Community Interest Company cannot claim Gift Aid or the tax reliefs available to registered charities, but it can claim ordinary business expenses and capital allowances against its profits.

See our can CICs claim Gift Aid guide for the full picture.

What happens if a CIC files its CT600 late?

HMRC imposes automatic penalties that start at £100 and increase the longer the return is outstanding, even where no tax is due. Filing on time through a professional CIC accountant avoids these penalties entirely.
