Corporation Tax FAQ's

A corporation tax return, also known as a CT600, is your company’s annual tax return. It shows your company’s taxable profit. Your company is liable to pay corporation tax on this profit. This figure consists of your company’s income minus expenses and any tax allowances.

As of March 2022, the current corporation tax rate is 19%, which generally applies to all companies, regardless of size.

From April 2023, the rate of corporation tax which is paid on company profits is expected to increase from 19% to 25%. As a caveat of this increase, a small profits rate of 19% will apply to companies whose profits are equal to or less than £50,000.

Once we’ve completed your corporation tax return, we’ll let you know how much corporation tax you must pay. You need to pay this sum within nine months and one day of your company’s year-end.

For example, if your company’s financial year-end is January 31, you would have to pay your corporation tax bill by November 1.

The easiest and quickest way to pay your corporation tax is online. The back of the payslip HMRC sends to you will tell you which account to use. If you’re not sure, use Cumbernauld or contact us to confirm.

You must also include your 17-character corporation tax payslip reference for the accounting period you’re paying. You can find this on any payslip that HMRC has sent you, or through your company’s HMRC online account.

You must submit your corporation tax return to HMRC within 12 months of your company’s financial year-end. If you fail to do so, you’ll be issued a penalty notice. The current penalties are:

  • One day late: £100
  • Three months late: a further £100
  • Six months late: HMRC will estimate your corporation tax due and add a penalty of 10 per cent
  • 12 months late: a further 10 per cent of any unpaid tax.
