The CT600 is a tax form used in the UK for companies to report their Corporation Tax to Her Majesty's Revenue and Customs (HMRC). The period of CT600 typically aligns with the company's financial year, which is a 12-month period. However, if the company's accounting period is longer than 12 months, due to it being the company's first year or for another reason, this period may be split into two returns. It's crucial to file your CT600 within 12 months after the end of the accounting period it covers.
