Corporation Tax Return: What You Need to Know

April 20, 2023

If you own a limited company in the UK, you are required to file a corporation tax return each year. This return reports your company’s profits and calculates how much corporation tax you owe to HM Revenue and Customs (HMRC).

Here’s what you need to know about corporation tax returns, including what they are, when they are due, and how to file them.

What is a Corporation Tax Return?

A corporation tax return is a form that you must file with HMRC to report your company’s profits and calculate how much corporation tax you owe. The form is called a CT600 and it includes information such as your company’s income, expenses, and capital allowances.

When is a Corporation Tax Return Due?

Your corporation tax return is due 12 months after the end of your accounting period. Your accounting period is typically the 12 months ending on your company’s financial year-end, although it can be longer or shorter in some cases.

For example, if your company’s financial year-end is December 31, your corporation tax return is due on December 31 of the following year.

It’s important to note that you must also pay any corporation tax owed by the same due date as your return.

How to File a Corporation Tax Return?

There are two ways to file a corporation tax return: online or by paper.

Online Filing

Online filing is the most common and recommended method of filing a corporation tax return. To file online, you must use HMRC’s online filing service or commercial software that is compatible with HMRC’s system.

When you file online, you must also pay any corporation tax owed electronically. You can pay using a debit or credit card, or by bank transfer.

Paper Filing

If you prefer to file by paper, you can download the CT600 form from HMRC’s website and complete it manually. You must then mail the form to HMRC along with any required attachments, such as your company’s accounts.

It’s important to note that paper filing takes longer to process and can result in penalties if your return is late or inaccurate.
