What Is Corporation Tax Filing?
Let’s be clear first on corporation tax filing. What is it? Corporation tax filing refers to submitting a company’s financial and tax-related information to the appropriate government authority. A corporate tax filing is a type of tax a company must pay on its profits or income. Generally, it is required to file a corporation tax return annually.
This return provides detailed information about the company’s financial activities, profits, deductions, and applicable tax credits.
Corporation tax filing in the UK means declaring an active limited company’s corporation tax liability to His Majesty’s Revenue and Customs (HMRC). Companies are responsible for paying this tax on their profits. It is a direct tax, meaning it is paid directly to the government. The Corporation Tax filing process typically involves completing a form called the CT600, which is available on the HMRC website.
You must pay Corporation Tax on profits from doing business as follows:
- A limited company.
- Any foreign company with a branch or office in the United Kingdom.
- A club, co-operative, or other unincorporated association, such as a community group or sports club.
Note: As part of their Corporation Tax return, businesses must submit their financial statements in iXBRL format to HMRC.
What Is Corporation Tax Form CT600?
A CT600 form is a document companies use to declare their taxable profits and losses for a given accounting period. It is a tax return form that businesses must complete and submit to HMRC within 12 months of the end of the financial year. The company determines the accounting period, which is usually 12 months long. During this time, companies must keep detailed records of their income, expenses, and other financial transactions.
The CT600 form is a component of a corporate tax return. When a company receives a “Tax Return Notice,” the form and other supporting documents are the corporate tax return, which must be submitted to HMRC. Limited Liability Companies use the information on the CT600 form to calculate the corporate tax owed to them.
