Corporation tax is being reformed and companies with profits of more than £50,000 will pay corporation tax at a higher rate than they do now.

While the changes do not come into effect for a year and start from 1 April 2023, their impact will be felt sooner where accounting periods span 1 April 2023. Consequently, they will be relevant to accounting periods of 12 months starting after 1 April 2022.

What are the changes?

From 1 April 2023, the rate of corporation tax that you pay will depend on the level of your profits and the number of associated companies that you have, if any.

If your profits are below the lower limit, from 1 April 2023, you will pay corporation tax at the small profits rate. At 19%, this is the same as the current rate of corporation tax.

If your profits are above the lower limit, you will pay corporation tax at the main rate. This has been set at 25% for the financial year 2023.

If your profits fall between the lower limit and the upper limit, you will pay corporation tax at the main rate, but you will receive marginal relief which will reduce the amount that you pay.

Where a company benefits from marginal relief, the effective rate of corporation tax will be between 19% and 25%. A company with profits nearer the lower limit will receive more marginal relief than a company with profits nearer the upper limit and pay tax at a lower rate.

The lower limit is £50,000 and the upper limit is £250,000 for a company with no associated companies. Where a company has one or more associated companies, the limits are divided by the number of associated companies plus 1, so that, for example, the lower limit for a company with one associated company will be £25,000 and the upper limit will be £125,000.

The limits are time apportioned where the accounting period (or pro rata period) is less than 12 months.

Now is the time to start planning ahead for these changes and we can help with this.
