How Is Corporation Tax Calculated?

Corporation tax is a form of tax imposed on limited companies and organizations in the UK. It is payable on any profits made by the company – including from business trading, property, investments, and overseas income. The rate of corporation tax is 19%, and this is the same rate for all companies regardless of size. 

To calculate your corporation tax liability, you will need to calculate your taxable profits. This is done by calculating your total profits for the year and then deducting any allowable expenses, such as wages, rent, and other costs. You will also need to add back any capital allowances that you have claimed. Once you have calculated your taxable profits, you can then calculate your corporation tax liability.

The first step is to calculate your total profits for the year. This is done by adding up all of your income and subtracting any allowable expenses. This figure is then multiplied by the current corporation tax rate of 19%. For example, if your total profits for the year were £50,000, you would multiply this figure by 19% and the resulting figure would be your corporation tax liability of £9,500.

The next step is to deduct any allowable expenses that you have paid. These expenses can include wages, rent, and other costs. Any expenses that you have claimed through capital allowances can also be deducted. This will reduce the total amount of corporation tax that you have to pay.

Finally, you will need to add back any capital allowances that you have claimed. This will increase the amount of corporation tax that you have to pay.

Once you have calculated your corporation tax liability, you will need to pay this amount to HMRC by the due date. It is important to pay your corporation tax on time, as failure to do so can result in penalties and interest charges.

Calculating your corporation tax liability can be a complex process, and it is important to seek professional advice if you are unsure of how to do this correctly. A professional accountant or tax adviser can help you to accurately calculate your corporation tax liability and ensure that you meet all of your filing and payment deadlines.
