Frequently Asked Questions
What is the UK tax-free allowance for 2025-26?
The personal allowance for 2025-26 is £12,570 for most people. This is the amount of income you can earn before paying income tax. Additional allowances apply if you're aged 65-74 (higher allowance) or 75+ (even higher allowance).
How is National Insurance calculated?
National Insurance is calculated on earnings above the threshold (£12,570 for employees in 2025-26). The employee contribution rate is 8% on earnings between £12,570-£50,270, and 2% above that. Self-employed rates are different.
Am I eligible for tax credits?
Tax credits depend on your income, working hours, and family situation. Working Tax Credit requires you to be working at least 16 hours/week. Child Tax Credit depends on income and number of children. Use our calculator for an estimate.
What percentage of my salary goes to taxes?
The effective tax rate varies by income. At £25,000, approximately 18% goes to income tax + NI. At £50,000, approximately 32%. At £100,000, approximately 42% (due to withdrawal of personal allowance).
Can I reduce my tax liability?
