Corporation Tax

Get the advice and support you need

Regardless of whether you have a complex corporation tax computation that requires attention or a comparatively straight forward company tax question, our team can help.

Every company in the UK must file an annual tax return (a CT600). Typically, this is due 12 months after the end of the period for which Statutory Accounts are prepared. However, the tax itself must be paid well head of this, typically just over 9 months after the period end. In addition, companies can face a significant number of issues during the year, ranging from EIS relief and R&D tax credits to navigating the intangible fixed assets regime. Care is required here and not all companies will be affected. Some smaller companies may have quite straight-forward tax calculations.

Things to consider

Where a company comes within the charge to corporation tax then under Finance Act 2004, s55, they have a duty to notify HMRC within 3 months. Thereafter, a company must file a return for each accounting period and formal Statutory Accounts must accompany the return. Complications can arise here as there is a technical difference between an accounting period and a period of account and claims for reductions can easily be missed and care is required. Deadlines must be met if penalties are to be avoided and taxable and accounting profit are also different.
