PAYE Tax Rates UK and Payroll Tax Reporting
The Pay As You Earn (PAYE) system is how UK employers deduct income tax and National Insurance contributions directly from employees’ salaries. Employers use the tax code provided by HMRC to calculate the correct deductions, and report payroll data through Real Time Information (RTI) submissions.
Accurate payroll processing ensures employees pay the correct amount of tax and helps businesses meet their HMRC reporting obligations. Any changes to tax codes or employee benefits should be reviewed promptly within the PAYE scheme.
For a detailed breakdown of PAYE rates, thresholds and RTI reporting, read our guide to PAYE tax rates in the UK
Personal Savings Allowance: What Business Owners Should Know
The Personal Savings Allowance (PSA) is relevant to company directors and business owners managing personal income from savings or retained profits. The amount of interest you can earn tax-free depends on your income tax band.
Taxpayer Type | Tax-Free Interest Allowance |
Basic rate taxpayer | £1,000 |
Higher rate taxpayer | £500 |
Additional rate taxpayer | £0 |
For a full guide on the Personal Savings Allowance and tax-free interest thresholds, read: How much interest can I earn tax free?.
Capital Gains Tax in the UK: An Overview
Capital gains tax (CGT) applies when you dispose of an asset — such as property, shares, business assets, or cryptocurrencies — for more than you originally paid. The rate depends on your income level and the type of asset.
Items subject to capital gains tax include:
- Property investments
- Shares and securities
- Business assets
- Cryptocurrencies
Every individual receives an annual CGT allowance, which reduces the amount of taxable profit on disposals. Keeping accurate records of purchase price, sale price, and allowable costs is essential for calculating any CGT liability.
For CGT rates, allowances, and legal strategies to reduce your liability, read our full guide to capital gains tax allowance in the UK.
Corporation Tax in the UK: Rates, Thresholds and Compliance
Corporation Tax Rates
Profit Range | Tax Rate |
Up to small profits threshold | 19% |
Above main rate threshold | 25% |
The rates above apply to profits after deducting allowable expenses.
Companies must file the following with HMRC:
- Corporation tax return (CT600)
- Annual accounts
- Supporting documentation
Businesses must also monitor corporation tax payment deadlines to avoid interest and penalties.
For full details on corporation tax rates, thresholds, marginal relief and payment deadlines, read our guide to corporation tax in the UK.
Reducing Your UK Corporation Tax Bill: Allowable Expenses and Reliefs
Businesses often look for legal ways to reduce their corporation tax liability. Strategic tax planning — through allowable expenses, capital allowances, and reliefs — can reduce taxable income and improve profitability.
Allowable expenses
Common allowable expenses that reduce taxable profits include:
- Staff wages and employer NI contributions
- Office rent and utilities
- Software subscriptions
- Business travel expenses
Capital allowances
Companies can also claim capital allowances on qualifying equipment and machinery purchases, reducing taxable profit in the year of acquisition.

Dividend Taxation UK: Rates, Bands and Allowances
Many company directors structure their remuneration to include dividends as a distribution of company profits. UK tax rules determine how dividends are taxed, with different rates applying depending on the recipient’s income tax band.
Dividend tax bands
| Income Tax Band | Dividend Tax Rate |
| Basic rate | 8.75% |
| Higher rate | 33.75% |
| Additional rate | 39.35% |
A dividend allowance applies each year, meaning the first portion of dividend income is not subject to dividend tax. Company directors and investors should factor this into their remuneration planning.

VAT Rates UK and VAT Compliance Requirements
VAT Category | Rate |

Frequently Asked Questions About UK Taxes
How does the UK tax system work?
The UK tax system is administered by HMRC and covers several types of tax — including income tax on earnings, corporation tax on business profits, VAT on sales, capital gains tax on asset disposals, and dividend tax on distributions. Each tax has its own rates, thresholds, and compliance requirements. Businesses are responsible for registering, filing, and paying the correct taxes on time.
What are the main types of tax in the UK?
The main taxes in the UK for businesses and individuals are: income tax, corporation tax, VAT (Value Added Tax), capital gains tax, dividend tax, and National Insurance contributions. Some businesses also pay business rates. Each tax operates under separate rules set by HMRC.
Who administers the UK tax system?
HMRC (His Majesty’s Revenue and Customs) is the UK government body responsible for collecting taxes, enforcing compliance, and providing guidance on tax obligations. Businesses must register with HMRC for relevant taxes and submit returns on time.
What is Making Tax Digital (MTD)?
Making Tax Digital is HMRC’s initiative requiring businesses to keep digital records and submit tax returns using compatible software. It is currently mandatory for VAT-registered businesses and is being extended to income tax self-assessment from April 2026. Businesses should begin preparing their digital record-keeping systems now to avoid penalties.
Do I need to pay both corporation tax and income tax?
It depends on your business structure. Limited companies pay corporation tax on their profits. Sole traders pay income tax on business profits through self-assessment. Company directors often pay both — corporation tax on company profits, then income tax or dividend tax on the personal income they draw from the business. Getting the structure right can significantly improve overall tax efficiency.
