What Is a Corporation Tax Return (CT600)?

A corporation tax return, known as the CT600, is a legal requirement for all UK limited companies. It must be submitted to HMRC annually and includes your company's profit, income, allowable expenses, tax reliefs, and ultimately the corporation tax owed.

Legal Requirement

Every UK limited company must file a CT600 with HMRC, regardless of profit or loss.

When Do You Need to File a Corporation Tax Return?

For Luton limited companies, timing is critical to avoid penalties

Filing Deadline

12 months after your company's financial year ends

Payment Deadline

9 months and 1 day after the end of the accounting period

Penalties for Late Filing or Non-Filing

Failing to file your corporation tax return (CT600) on time can lead to significant penalties from HMRC

Late payment also incurs daily interest charges until the tax is fully paid. HMRC may also issue an estimated tax bill if you fail to file, which may be higher than your actual liability.
