Tax law is complex. This guide explains the key obligations most UK individuals face - in plain terms - so you know where you stand.
Income Tax is charged on earnings above the Personal Allowance. For the 2024/25 tax year, the Personal Allowance is £12,570 - meaning the first £12,570 you earn is tax-free. Earnings between £12,571 and £50,270 are taxed at the Basic Rate of 20%. Earnings between £50,271 and £125,140 are taxed at the Higher Rate of 40%. Anything above £125,140 is taxed at the Additional Rate of 45%.
If you earn over £100,000, your Personal Allowance reduces by £1 for every £2 earned above that threshold. At £125,140, it disappears entirely.
Scottish taxpayers pay rates set by the Scottish Government, which differ slightly from the rest of the UK.
National Insurance Contributions (NICs) are separate from Income Tax. They fund the State Pension, NHS, and other state benefits.
Employees (Class 1)
Self-Employed (Class 4)
Class 2 NICs (a flat weekly charge for the self-employed) were abolished from April 2024.
Capital Gains Tax (CGT) applies when you sell or dispose of an asset that has increased in value - including shares, investment funds, second properties, and certain personal possessions worth over £6,000.
Each individual has an Annual Exempt Amount of £3,000 for 2024/25. Gains above this are taxed depending on the asset type and your income tax band. For residential property, basic rate taxpayers pay 18% and higher or additional rate taxpayers pay 24%. For other assets such as shares and funds, basic rate taxpayers pay 10% and higher or additional rate taxpayers pay 20%.
Your main home is exempt under Private Residence Relief in most circumstances.
Personal Savings Allowance
Interest above your allowance is taxed at your marginal Income Tax rate.
Dividend Allowance
The first £500 of dividend income per year is tax-free. Above this, dividends are taxed at 8.75% (basic rate), 33.75% (higher rate), or 39.35% (additional rate).
ISAs
Individual Savings Accounts allow you to save or invest up to £20,000 per tax year completely free of Income Tax, CGT, and Dividend Tax. Returns inside an ISA are never taxable.
If you work for yourself, you report your income and pay your own tax through Self Assessment. You can deduct allowable business expenses from your income before tax is calculated.
Allowable expenses are costs that are wholly and exclusively for business purposes - equipment, professional subscriptions, travel to clients, and certain home office costs.
Good record-keeping is essential. HMRC can request supporting evidence for any item on your return.
Inheritance Tax (IHT) is charged at 40% on the value of an estate above the nil-rate band.
The standard nil-rate band is £325,000. An additional Residence Nil-Rate Band of £175,000 applies when a main residence passes to direct descendants, bringing the combined threshold to £500,000 for eligible estates.
Unused nil-rate bands can transfer to a surviving spouse, potentially doubling the effective threshold to £1 million.
Key exemptions and reliefs include:
IHT planning is complex. A specialist can help you understand your estate's position and identify ways to reduce the eventual liability.
If you are unsure whether something needs to be declared, whether an expense qualifies, or how a life change affects your tax position - ask a qualified specialist.
Getting the right advice early is almost always less expensive than correcting an error later.
