UK Income Tax Rates and Income Tax Levels Explained
The UK income tax system is based on progressive income tax levels, where different portions of income are taxed at different rates.
The table below provides a simplified income tax chart based on current income tax rates:
Tax Band | Tax Rate |
Personal allowance | 0% |
Basic rate | 20% |
Higher rate | 40% |
Additional rate | 45% |
These bands apply to income over the personal allowance, which is subject to change in line with government Budget announcements.

Practical insight for businesses
From a business perspective, income tax levels play a key role in director remuneration planning. Many directors structure earnings through a mix of salary and dividends to improve tax efficiency while remaining compliant with HMRC regulations.
HMRC Changing Tax Code: Reasons, Updates and What Businesses Should Do
Tax code changes are a common source of payroll queries for businesses and their employees. A tax code is used to calculate how much tax is paid through the PAYE system.
HMRC changes tax codes when:
- Employment income changes
- Benefits in kind are reported
- Pension contributions change
- Unpaid tax is recovered
Where tax codes are incorrect, employees may underpay or overpay tax, resulting in an unexpected liability or a repayment claim.
It is important for businesses to regularly check their payroll records to ensure that the PAYE deductions are correct. For more information about how to make corrections and learn about the process, learn more about HMRC changing tax codes.
PAYE Tax Rates UK and Payroll Tax Reporting
The Pay As You Earn (PAYE) system is a method by which employers in the UK deduct income taxes and National Insurance contributions directly from the salaries of their employees. To calculate the correct deductions, employers use a tax code given by HMRC, and then report the payroll data through Real Time Information (RTI) returns.
Accurate payroll processing helps ensure that employees are paying the right amount of tax, as well as helping the business comply with HMRC reporting obligations. Any changes in tax codes, as well as employee benefits, need to be reviewed in relation to the PAYE scheme.
For a deeper explanation, understand PAYE tax rates UK and payroll reporting.
How Much Interest Can I Earn Tax Free?
While primarily relevant to individuals, the Personal Savings Allowance can also impact company directors and business owners managing personal income from savings or retained profits.
Taxpayer Type | Tax-Free Interest |
Basic rate taxpayer | £1,000 |
Higher rate taxpayer | £500 |
Additional rate taxpayer | £0 |
This means that many individuals can earn money from their savings without having to pay income tax.
For directors and business owners managing surplus funds or personal savings, understanding the PSA is relevant to personal tax planning. Learn more about how much interest you can earn tax-free.
Capital Gains Tax UK: Rates, Allowances and Capital Gain Tax
Capital gains tax rates depend on income levels and asset type, making it important to understand capital gains tax allowances and applicable percentages.
Items subject to capital gains tax include:
- Property investments
- Shares
- Business assets
- Cryptocurrencies
Capital Gain Tax
When calculating the tax payable on the capital gain, HMRC takes into account the following:
- Purchase price
- Sale price
- Allowable costs
- Annual allowance
Documentation is vital for businesses and investors when it comes to the calculation of CGT.
Capital Gain Tax Allowance UK
Every year, individuals are given a capital gain tax allowance, which reduces the amount of taxable profit.
Example:
Asset sale profit | CGT allowance | Taxable gain |
£10,000 | £3,000 | £7,000 |
The amount of this allowance changes periodically in line with changes in UK tax policy.
Businesses looking to dispose of company assets should do so in a way that minimises tax risk.
How to Reduce Capital Gains Tax Legally
While capital gains tax cannot be avoided entirely, businesses and investors can apply legal strategies to reduce capital gains tax exposure.
The ways of reducing tax legally are:
- Utilising the CGT annual exemption
- Transferring assets to a spouse
- Utilising capital losses
- Utilising ISA investments
These are all legitimate strategies recognised under UK tax legislation.
