Corporation tax planning for a Bristol business
What is corporation tax?

The basics, in plain English

All limited companies must file a Corporation Tax Return (the CT600) with HMRC within 12 months of the end of the financial year. It's based on gains made during your Accounting Period (AP) — and you must complete one even if you made a loss.

An Accounting Period should never be longer than 12 months. Although the CT600 is due within 12 months of year-end, the payment must be made within 9 months and 1 day. Late returns are penalised and late payments incur interest.

Corporation tax is not payable by sole traders, individuals or partnerships — they pay via self-assessment (SA302) instead.

How we help

Compliance plus proactive planning

CT600 filing

All limited companies must file a Corporation Tax Return (CT600) with HMRC — even if you made a loss.

Deadline management

The return is due within 12 months of year-end, but payment is due within 9 months and 1 day. We track both.
