Corporation tax FAQs
Corporation tax is the tax a company pays on its profits. Every UK-based limited company must pay it, and even non-UK companies trading in the UK may be liable. We handle the whole return for limited companies of all sizes.

Your CT600 is normally due 12 months after the end of your accounting period, but the tax itself is usually payable earlier — 9 months and one day after the period ends. We make sure both the payment and filing deadlines are met so you avoid penalties and interest.
