What is Company Tax?

Company tax (or corporation tax) is the tax levied on a company's taxable income. Rates vary by country and sometimes by company size.

Company tax is the tax imposed on the profits of incorporated businesses. Unlike sole traders (who pay individual income tax on business profits), companies are separate legal entities that pay tax at corporate rates. Current company tax rates include: Australia 25% for base rate entities (turnover under $50 million) and 30% for others, UK 25% main rate (19% for small profits under GBP 50,000), US 21% federal rate, Canada varies by province (approximately 15% federal for small businesses), Singapore 17%, Ireland 12.5% and many others. Company tax is calculated on taxable income (accounting profit adjusted for tax differences) and paid annually or in instalments. Companies must lodge annual tax returns and may need to make provisional or instalment payments throughout the year. Understanding your company tax rate and obligations is essential for cash flow planning and tax minimisation strategies.
