What is corporate tax?
Companies and individuals paid taxes alike until 1965, with an additional profits tax. Finance Act 1965 introduced corporation tax. Since then, the corporation tax system has undergone many systematic changes. It is projected that for the 2020-21 tax year, it accounts for circa £40 Billion, 5% of the UK’s total receipts.
The rate of corporation tax for all limited companies has been 19% since the year 2016. Companies don’t receive any tax-free allowance and must pay tax on all profits.

Taxable profits
Profits for corporation tax include the money company makes from:

Taxation for resident and non-resident companies
In the United Kingdom, you can describe tax structure in a very simplified manner. The division is made based on resident & non-resident companies.
Resident companies have to pay the tax on the profits they earn worldwide, while non-residents have to tackle UK-based profits.
General and special corporation tax regime
While examining the system, the essential aspects to consider are the taxes levied on corporate income, which are of two types general & special tax systems. After that, the prominent elements to look at are available & special rates along with other taxes.
| General Rates | 19% |
| Special Rates | No special provision apart from the below-mentioned companies: • Oil & gas company • Life insurance • Tonnage tax • Banking sector |
Oil & gas company
Profits that arise from oil or gas extraction, gas rights in the United Kingdom are subject to tax in the UK itself following rates of 2006, including a total rate of 30% and a low rate of 19%.
Life insurance company
Life Insurance also comes under different tax regimes, including different rates and rules for quantifying profits.
Tonnage tax
Companies that operate qualifying ships managed in the United Kingdom can choose to apply to the tonnage scheme. They need to tonnage tax in place of corporation tax. It replaces the tax-adjusted profit/loss on the shipping business.
Banking sector
An additional tax of 8% applies to companies in the banking sector over GBP 25 million. The loss utilization is also restricted; carried forward trading losses can be set against only 25% of profits.
Diverted profit tax (DPT)
DPT introduced in 2015 is a part of the UK’s response to the shifting tax environment and is separate from other taxes. It applies to diverted profits at the rate of 25%.
For accounting periods beginning on or after 1 April 2023, it will rise to 31%.
It may apply in two cases:
- Where companies create a tax benefit by making transactions lacking economic substance.
- Where foreign companies are operating to avoid setting up a UK permanent establishment.
The list of situations not within the scope of DPT are:
- The parties are small or medium-sized businesses
- Tax mismatch arises from loan relationships
- Receipt of payments by pension funds, charities, investment funds, and the person with sovereign immunity.

Corporate tax deadlines
This is where corporate tax gets complicated as the payment deadline is different from other taxes and depends on the accounting period. The crucial points to keep in mind are:
- You need first to pay corporation tax before tax return.
- The deadline to pay tax is nine months and one day after the end of your accounting period.
- The deadline to submit the tax return is twelve months after the end of the accounting period.
- You may have two accounting periods because your accounting period is longer than 12 months.
For example,If you set up a company on 10 January 2021, the first accounting period will be up from 10 January 2021 to 31 January 2022.
Your first tax period will usually be from 10 January 2021 to 09 January 2022, and the second tax period will be from 10 January 2022 to 31 January 2022.
Just remember, the tax return CT600 period cannot exceed 365 days except where there is a leap year.
- Businesses with more than £1.5 million in profits will need to pay their Corporation Tax in installments.
