How to successfully pay Corporation Tax

Corporation Tax is the key tax a limited company has to pay each year. Our guide to paying Corporation Tax will help ensure you meet tax deadlines and show you the best way to pay

Paying Corporation Tax on any profits your small business makes if it’s registered as a limited company is a legal requirement.

After filing your accounts with HM Revenue & Customs (HMRC), you’ll need to pay Corporation Tax on any profits for the financial year.

Profit is money your business made after all allowable expenses and costs, such as salaries. There are also tax relief and allowances that can be applied to your company profits to lower you Corporation Tax liability.


When does my small business have to pay Corporation Tax?

Depending on the profits your business makes, the deadline for paying Corporation Tax will be different.

If your taxable profits are less than £1.5m, your business has 9 months and 1 day after the end of the accounting period to pay the Corporation Tax that’s due.

The accounting period is usually the financial year of your business – start-ups can have two periods in the first year they were established.

If your taxable profits are above £1.5m, then your business has to pay HMRC in instalments – usually every three months following the first instalment.


How do I pay Corporation Tax?

HMRC offers several ways to pay Corporation Tax, and it is worth noting the deadline of when you need to pay.

If you miss a deadline, you’ll be liable for interest payments on the outstanding amount. However, if you pay your Corporation Tax early, HMRC will pay interest to your business.

Corporation Tax can be paid electronically, and at the Post Office or your bank, depending on how quickly want the payment to clear with HMRC.

In all cases, you’ll need to quote you 17-digit Corporation Tax reference number for the accounting period you’re paying for.
