Navigating the UK's tax system is essential for effective financial planning. As of the 2025/26 tax year, several updates and considerations have emerged that taxpayers should be aware of.
What is the Personal Allowance for 2025/26 in the UK?
The UK Personal Allowance—the amount you can earn before paying income tax—remains at £12,570 for the 2025/26 tax year. This threshold has been frozen until April 2028, meaning it will not rise with inflation or wage growth. Consequently, as incomes increase, more individuals may find themselves in higher tax brackets, a phenomenon known as fiscal drag.
Income Tax Bands and Rates for 2025/26
After the Personal Allowance, income is taxed as follows:
Basic Rate (20%): Income between £12,571 and £50,270
Higher Rate (40%): Income between £50,271 and £125,140
Additional Rate (45%): Income over £125,140
Notably, the number of higher-rate taxpayers has increased significantly, with over 5.1 million people now paying the 40% rate. This surge is largely due to the freezing of tax thresholds. thesun.co.uk

Earnings Before Paying 40% Tax
You begin paying the 40% tax rate on income exceeding £50,270. This includes all taxable income sources such as salaries, bonuses, rental income, and certain investments.
Impact on Pensioners
For pensioners, the Personal Allowance remains £12,570. However, increases in the state pension, driven by the 'triple lock' policy, have pushed more retirees into the taxable income bracket. In 2024, nearly 700,000 pensioners received tax bills averaging £665, highlighting the importance for retirees to monitor their total income. The Scottish Sun
Strategies to Mitigate Higher Tax Rates
To reduce exposure to higher tax rates:
Pension Contributions: Contributing more to your pension can lower your taxable income.The Scottish Sun
Salary Sacrifice Schemes: Opting for benefits like childcare vouchers can reduce your gross income.
Charitable Donations: Donations via Gift Aid can provide tax relief.

National Insurance Contributions (NICs)
Employees start paying Class 1 NICs on earnings above £242 per week (£12,570 per year). This aligns with the Personal Allowance threshold. Recent policy changes have reduced NIC rates, with further cuts anticipated.
Recent Tax Developments
Several noteworthy updates have emerged:
Potential Tax Adjustments: Economists warn that Chancellor Rachel Reeves may introduce £24 billion in tax hikes and spending cuts due to budget constraints. Stealth taxes, such as freezing thresholds, are expected to push more individuals into higher tax brackets. thesun.co.uk
