Corporation Tax is a tax levied on the profits of UK-based companies and organisations. Unlike income tax, which applies to individuals, Corporation Tax is paid by limited companies, foreign companies with UK branches, and certain organisations on the profits they generate from trading, investments, or selling assets. The tax applies to all profits, including revenue from business activities, investments, and capital gains.
Corporation Tax is an essential part of running a limited company in the UK. Accurate calculation and timely payment of Corporation Tax ensure compliance with HMRC regulations and avoid penalties or interest for late payments. Companies must prepare annual accounts and compute taxable profits based on revenue minus allowable expenses, reliefs, and deductions. Filing a Company Tax Return with HMRC is a legal requirement, and the process integrates with other accounting practices, such as bookkeeping and payroll, to maintain accurate financial records. Proper Corporation Tax management helps businesses plan their finances, reinvest profits, and make informed decisions for growth.
In the UK, all limited companies must pay Corporation Tax on their profits, regardless of whether they are actively trading or dormant. This includes private limited companies (Ltd), public limited companies (PLC), and certain clubs, associations, or organisations that generate taxable profits. Companies with UK branches but registered abroad may also be liable for UK Corporation Tax on profits earned within the country.
Sole traders and partnerships do not pay Corporation Tax; instead, they pay Income Tax on their business profits through Self Assessment. However, limited company directors must ensure that their company’s taxable profits are calculated accurately, Corporation Tax returns are filed on time, and payments are made by HMRC deadlines. Proper management of Corporation Tax is crucial for compliance, avoiding fines, and maintaining a transparent financial record for investors, lenders, and regulatory authorities.

Corporation Tax is a mandatory tax levied on the profits of UK-registered limited companies. Every active company must file a Corporation Tax Return (CT600) with HMRC within 12 months of the financial year-end. However, tax payments are due within 9 months and 1 day after the accounting period ends.
Failure to meet these deadlines can lead to significant penalties and interest charges. Affotax ensures your tax returns are prepared accurately and submitted on time, preventing unnecessary financial burdens.
