The tax rules and obligations of limited companies in England and Wales differ from those of sole trader and partnership businesses. If you own a limited company, then it is important to understand how taxes are calculated to ensure ongoing compliance with the company tax regime. In 2025, limited companies in the UK pay Corporation Tax at a rate of between 19% and 25% depending upon how much profit they make each year. Furthermore, Value Added Tax (VAT) and employer’s National Insurance contributions (NIC) may also be payable to HMRC. In this article, we will explain how much tax limited companies pay, the penalties for late payments and how to reduce company tax liabilities.
Understanding the Basics of UK Limited Company Taxation
What is corporation tax in the UK?
Corporation Tax is a tax paid by limited companies in the UK to HM Revenue and Customs (HMRC) on any profits made in the ‘accounting period’. The exact amount of corporation tax payable to HMRC is based on the amount of profit made. Corporation tax is payable by
- Limited companies
- Foreign companies with a UK branch or office, and
- Clubs, co-operatives or other unincorporated associations (e.g. sports clubs).
It is important to understand that you will not simply receive an automatic bill for the payment of Corporation Tax; rather, your business will need to prepare and submit annual accounts and a tax return.
When do I need to register for VAT?
Limited companies in the UK are legally required to register with HMRC for Corporation Tax within three months of starting their business activities. The corporation tax registration process involves sending details of the company’s structure, activities, and accounting reference dates to HMRC.
What is a company’s Accounting Reference Date (ARD)?
The Accounting Reference Date (ARD) is often referred to as the “year-end” or “financial year-end”. For new companies, it is the last day of the month in which the first anniversary of incorporation falls. For example, if your company was incorporated with Companies House on 7th January 2023, then its initial ARD will be 31st January 2024. The company must then make its accounts up to 7 days on either side of its ARD.
How Corporation Tax Applies to UK Limited Companies
Corporation tax in the UK is payable on any profit made from the income of a limited company within a specific accounting period. This applies to profit made from income from trading, investment, and capital gains.
It is crucial for businesses to forecast and calculate accurately their taxable profits to ensure that they comply with HMRC’s taxation regime. This requires an understanding of the rates of Corporation Tax in addition to any eligible deductions, allowances, and reliefs that can reduce the overall amount of tax that must be paid. Working closely with a trusted professional accountant or tax advisor is essential in correctly calculating and reducing a company’s tax liabilities.
The Current Corporation Tax Rate for UK Limited Companies
For the 2025/2026 tax year, the rates of corporation tax will remain the same as they were in the 2024/2025 tax year. This means that the current standard rates of Corporation Tax that apply to UK limited companies are as follows:
| Profit | Rate |
|---|---|
|
Under £50,000 |
19% (this is the “small profits rate”) |
|
Between £50,000 and £250,000 |
Marginal relief provides a gradual increase in Corporation Tax rate between 19% and 25%. |
|
Over £250,000 |
25% (this is the “main rate”) |
How to calculate Marginal Relief on your Corporation Tax
If your company’s profit is between £50,000 and £250,000, the amount of corporation tax payable in the tax year depends on how much Marginal Relief can be claimed. To work out how much Marginal Relief you can claim against your Corporation Tax, you can use the HMRC’s Marginal Relief calculator. This can be helpful in assessing whether your company is eligible for Marginal Relief, the amount of Marginal Relief your company is entitled to, and your Corporation Tax and effective tax rates before and after Marginal Relief. To calculate your Marginal relief using this method, you will need your company’s:
- Accounting period start and end dates
- Total taxable profit and
- Distributions from non-group, unassociated companies
How to calculate your limited company’s taxable profits
What is taxable profit when calculating corporation tax?
“Taxable profit” is the amount of money made by a limited company minus any allowable business expenses such as stock, rent, utilities and wages. It is also important to note that limited companies in the UK pay Corporation Tax on all profits both from the UK and from businesses overseas.
For the purposes of calculating taxable profits, allowable expenses are costs that a limited company pays either wholly or exclusively for the purpose of its trade. These may include rent, utilities, salaries, uniforms, IT costs, and any other essential business expenditures. In addition, certain capital allowances may apply to reduce further the amount of Corporation Tax payable to HMRC. Capital allowances, including the Annual Investment Allowance, let businesses deduct the cost of certain assets – such as equipment and machinery – from taxable profits.
How do I calculate corporation tax?
There are three main steps in calculating a limited company’s taxable profits:
- Calculate the total amount of revenue for the tax year;
- Deduct the cost of any business expenses (e.g. travel, electricity, water and rent) and then:
- Deduct any pension contributions and gross salaries.
To ensure that your limited company’s taxable profits are correctly calculated, it is essential that you partner with a trusted accounting professional who can manage your annual Corporation Tax return.
The Role of Dividend Tax in Limited Company Taxation
The payment of dividends allows business owners and shareholders to take profits from a limited company, although tax must be paid on these amounts. Dividend tax is paid to HMRC only if the individual’s income exceeds their personal tax allowance (which is currently £12,570 p.a.). In addition to the standard personal tax allowance, those receiving dividends also have a dividend allowance. You will only pay personal tax on any dividend income that you receive from your company that exceeds the dividend allowance. For the tax period from 6th April 2024 to 5th April 2025, the dividend allowance is £500 per annum. This marks a reduction of £500 from the 2023/2024 dividend tax rate, which was set at £1,000.
How much dividend tax must be paid depends on the total amount of dividends received in the tax year, as follows:
| Tax band | Dividend amount | Dividend tax rate |
|---|---|---|
|
Basic rate |
£12,571 to £50,270 |
8.75% |
|
Higher rate |
£50,271 to £125,140 |
33.75% |
|
Additional rate |
Over £125,140 |
39.35% |
For example, if you receive £3,000 in dividends from your company and earn £29,570 in wages in the 2024 to 2025 tax year, you have a total income of £32,570. Taking into account your personal Allowance of £12,570, you then have a taxable income of £20,000. Based on this income, you would pay 20% tax on your £17,000 wages, zero tax on the first £500 received in the form of dividends, and 8.75% tax on £2,500 of dividends.
Understanding VAT and How it Affects Limited Companies
Value Added Tax (VAT) must be paid by businesses with a turnover for the last 12 months of £90,000 (the VAT threshold) or more. Limited companies are also required to register for VAT if they expect turnover to exceed £90,000 in the next 30 days, even if this has not yet happened. In turn, VAT-registered limited companies charge VAT on their sales.
VAT owed can be reduced by reclaiming VAT on allowable business expenses. There are also different VAT schemes, including the Flat Rate Scheme and the Cash Accounting Scheme, which offer businesses flexibility in how they manage their VAT obligations.
The Effect of Business Rates on Your Limited Company
Limited companies that operate from commercial premises, such as an office, shop, licensed premises, warehouse, factory or holiday rental home, should be aware of their obligations to pay business rates.
Business rates are charged by and payable to local authorities, rather than HMRC, based on a “rateable value” (the open market rental value as of 1st April 2021). The rateable value is calculated by the Valuation Office Agency (VOA) and depends upon the property’s location and value. If you believe that your rateable value is too high, then you should inform the VOA as soon as you can.
Various business rate relief schemes also apply in England and Wales to reduce the amount payable. Such schemes include the Small Business Rate Relief (SBRR) for businesses with a low rateable value or other sector-specific reliefs.
How to calculate your business rates for 2025
To calculate your business rates for 2025, there are three key steps:
- Get the rateable value of your business property.
- Check which “multiplier” to use – you will need to use the standard multiplier if your rateable value is £51,000 or over or the small business multiplier if your business’s rateable value is less than £51,000.
- Multiply your rateable value by your multiplier (see below).
- Deduct any business rate relief that your business is entitled to.
This gives you the amount that you will need to pay in business rates for 2024/2025:
| Year | Standard multiplier | Small business multiplier |
|---|---|---|
|
2024 to 2025 |
54.6 pence |
49.9 pence |
|
2023 to 2024 |
51.2 pence |
49.9 pence |
How to Pay Your Limited Company’s Tax Bill
The deadline for paying Corporation Tax is nine months and one day after the end of the accounting period for the last financial year. For example, if the accounting period ends on 30th April, then the corporation’s tax payment deadline will be on 1st February of the following year.
Corporation tax can be paid to HMRC by various methods including direct bank transfer, online payment, direct debit or at a bank or building society.
Consequences of Late or Non-Payment of Company Taxes in 2025
Late or non-payment of taxes can have negative consequences for a limited company. Depending upon the circumstances, HMRC may levy penalties and interest charges, which may increase the total that is owed. HMRC provides options for businesses facing financial challenges, such as setting up payment plans or negotiating time-to-pay arrangements.
The penalties for late payment are as follows:
| Time after deadline | Penalty |
|---|---|
|
1 day |
£100 |
|
3 months |
Another £100 |
|
6 months |
HMRC will estimate the Corporation Tax owed and add a penalty of 10% |
|
12 months |
Another 10% of any unpaid tax |
If HMRC determines that your tax return is late 3 times in a row, the £100 penalties will be increased to £500 each.
One may sometimes appeal against a penalty for late payment if there is a reasonable excuse (e.g. serious illness or the death of a close family member).
Tax planning strategies for UK limited companies
Using all of the available tax reliefs and allowances and staying informed about changes in tax legislation can help businesses reduce their tax liabilities. Tax planning strategies may include:
- Tax-efficient ways to extract profits.
- Using research and development (R&D) tax credits.
- Optimising capital allowances – e.g. using the Annual Investment Allowance (AIA) and First-Year Allowances (FYA).
Given the range of tax allowances and credits available for limited companies, it is important to seek the expertise of an accountant who understands the tax rules and will reflect these properly within your annual accounts and returns.
Final Words
The company tax regime in the UK is evolving constantly. A corporate tax strategy that works today may not be effective in the future. Hence, it is important to review regularly how your tax is calculated and how this may affect important business decisions. Effectively managing UK limited company taxation involves having a solid grasp of Corporation Tax, VAT and business rates. It is also important to understand the wide range of allowances and deductions that can legally reduce how much corporation tax must be paid. Limited company owners also need to comply with their legal obligations to keep accurate financial records and ensure that filing and payments are completed by the deadlines given by HMRC. By partnering with a knowledgeable, trustworthy and expert company accountant you can relax in the knowledge that your corporation tax is fully in hand and as efficient as possible.
