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.
When Do You Need to File a Corporation Tax Return?
For Luton limited companies, the deadline to file your corporation tax return is 12 months after your company’s financial year ends, but corporation tax must usually be paid within 9 months and 1 day after the end of the accounting period.
