Professional Community Interest Company corporation tax return CT600 filing services across the UK. Our qualified CIC accountants prepare your Corporation Tax computation, submit your CT600 form to HMRC and manage your deadlines, so your social enterprise stays compliant without the stress.
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.
A CIC corporation tax return CT600 is the form a Community Interest Company files with HMRC to report its taxable profits, claim reliefs and settle its Corporation Tax liability for each accounting period.
| Requirement | What It Means for Your CIC |
|---|---|
| Corporation Tax registration | Every CIC must register for Corporation Tax with HMRC within three months of starting to trade. |
| CT600 filing deadline | The return must be filed within 12 months of the end of your accounting period. |
| Payment deadline | Any Corporation Tax due is payable within nine months and one day of your year end. |
| Penalties | Late filing attracts automatic penalties starting from £100, rising the longer the return is outstanding. |
