What Is a Company Tax Return (CT600)?
A company tax return, also known as a CT600, is a legal requirement for all UK limited companies. It reports your company’s taxable profits and calculates how much Corporation Tax is due for each accounting period.
The return must be submitted to HMRC along with:
- Statutory company accounts
- Detailed tax computations
- Supporting schedules where required
Even if your company makes no profit or a loss, a CT600 usually still needs to be filed. Accurate preparation is essential to avoid penalties and unnecessary HMRC enquiries.
When Is Corporation Tax Due?
- Corporation Tax deadlines depend on your company’s accounting period, but in most cases:
- Corporation Tax is due 9 months and 1 day after the end of the accounting period
- The CT600 tax return must be submitted within 12 months of the period end
Missing these deadlines can result in:
- Automatic penalties
- Interest on unpaid tax
- Increased HMRC scrutiny
Early preparation helps ensure you pay the correct amount, on time, without last-minute pressure.
What Happens If You File Your Company Tax Return Late?
Late or incorrect company tax returns can trigger:
- Fixed penalties for late submission
- Daily penalties for continued delays
- Interest on unpaid Corporation Tax
- HMRC compliance checks or enquiries
Even small errors can cause delays or investigations. Working with experienced accountants helps reduce risk and ensures your return is filed correctly the first time.

We help businesses reduce Corporation Tax by:
- Identifying allowable business expenses
- Reviewing capital allowances
- Advising on dividend planning
- Ensuring reliefs are claimed correctly
- Structuring profits efficiently
Our focus is always on legal, HMRC-compliant tax efficiency.
