Key Takeaways How Does Income Tax Work in the UK? 1.1 The Tax Brackets Explained Income tax in the UK is progressive. This means the more you earn, the higher the tax rate on your income. Here’s what 2025 looks like: Tax Band Taxable Income (£) Tax Rate (%) Personal Allowance 0 – 12,570 0% Basic Rate 12,571 – 50,270 20% Higher Rate 50,271 – 125,140 40% Additional Rate 125,141+ 45% 1.2 Allowances to Keep in Mind 1.3 Key Differences: Allowances, Bands, Thresholds, and Limits Non-Taxable Income Sources Personal Allowance Each individual is entitled to a personal allowance, which is the amount of income they can receive tax-free. For the tax year 2023–24, the standard personal allowance is £12,570. However, this allowance is gradually withdrawn for individuals with incomes exceeding £100,000, effectively creating a higher marginal tax rate within that income bracket. Income Tax Bands and Rates In England, Wales, and Northern Ireland, the income tax bands and rates for the tax year 2025 are as follows: It’s important to note that Scotland has its income tax rates and bands, which differ from the rest of the UK. Tax Tips for 2025 Keep Records: Save receipts and invoices for at least 5 years. Seek Advice: Unsure about tax? Consult a tax advisor or use free HMRC helplines. Plan Ahead: Use budgeting tools to set aside tax payments monthly. Marginal and Average Tax Rates Understanding these rates is crucial for financial planning, affecting decisions like additional earnings and investments. Tax Reliefs and Deductions Certain payments can be deducted from your taxable income, reducing your tax liability: High-Income Child Benefit Charge (HICBC) Families receiving child benefits may be subject to the HICBC if the highest-income parent earns over £50,000. The charge effectively reduces the benefit received as income increases. Important Deadlines Task Deadline Register for Self-Assessment 5 October 2025 Submit Paper Tax Return 31 October 2025 Submit Online Tax Return 31 January 2026 Pay Any Tax Owed 31 January 2026 Missing these dates can result in penalties of £100 or more.
