Understanding your company tax return

Understanding your company tax return

Every limited company in the UK must pay Corporation Tax on its profits. That includes profits coming from trading, investments, or even selling assets.

Your company tax return (also known as the Corporation Tax return or CT600) is the document you send to HMRC to make sure it's all tax-compliant. This is how you report your income, business expenses, profits, losses, and any tax reliefs you're claiming.

How much you pay depends on how much profit you make.

When is Corporation Tax due?

When is Corporation Tax due?

Corporation Tax is usually due nine months and one day after the end of your accounting period.

So, for example:

If your year-end is 31 March, you'll need to pay Corporation Tax by 1 January the following year.

Your company tax return (CT600) is filed later, normally 12 months after the end of the same accounting period (or three months after you pay Corporation Tax).

For example

If your year-end is 31 March, your Corporation Tax return is due by 31 March the following year.

Because HMRC works differently from Companies House, you end up with two separate deadlines. This can get confusing.

We're here so you don't miss them, saving you from penalties, interest, and unnecessary stress.

How is a Corporation Tax bill calculated?

How is a Corporation Tax bill calculated?

Your Corporation Tax bill is based on your company's taxable profits, essentially your income minus allowable business expenses and any other adjustments.

HMRC looks at:

  • Trading profits
  • Investment income
  • Chargeable gains
  • Allowable and disallowed expenses
  • Capital allowances
  • Reliefs and losses

We take the guesswork out of it. Using fast and efficient online software, we calculate your taxable profits to the last penny and advise you on how to reduce your bill where possible.
