Understanding UK Tax Years and When Changes Occur
The UK tax year runs from 6 April to 5 April the following year. For 2024-25, this covers 6 April 2024 to 5 April 2025, while 2025-26 spans 6 April 2025 to 5 April 2026. Tax rates and thresholds are typically announced in the annual Budget, with most changes taking effect at the start of the new tax year. However, mid-year adjustments can happen due to economic shifts or policy decisions.
In the 2024 Spring Budget and subsequent announcements, several updates were made for these periods, including freezes on certain thresholds and tweaks to National Insurance contributions. For instance, the personal allowance remains frozen at £12,570 until at least 2028, impacting how much tax-free income you can earn. Keeping track of these is essential, as non-compliance can lead to fines up to 100% of the tax owed.
To illustrate, if you’re self-employed and your profits rise unexpectedly, you might cross into a higher tax band mid-year. Always review your finances quarterly to anticipate changes. Tools like HMRC’s online calculators can help, but for personalized advice, consider professional support.

Income Tax: Allowances, Rates, and Bands
Income tax is one of the primary taxes for self-employed individuals and employees. It’s calculated on your taxable income after deductions like the personal allowance and allowable expenses. For employers, understanding these rates is key for accurate PAYE (Pay As You Earn) deductions.
The Personal Allowance and How It Works
The personal allowance is the amount you can earn tax-free each year. For both 2024-25 and 2025-26, it stands at £12,570. This applies to most people, but it tapers if your adjusted net income exceeds £100,000—reducing by £1 for every £2 over this threshold, reaching zero at £125,140.
Example: A self-employed graphic designer earning £110,000 in 2025-26 would see their personal allowance reduced by £5,000 (half of the £10,000 excess over £100,000), leaving them with £7,570 tax-free.
Tip: If you’re married or in a civil partnership, you might qualify for the Marriage Allowance, transferring £1,260 of your personal allowance to your partner for a tax saving of up to £252.
For blind individuals, the Blind Person’s Allowance adds £3,070 in 2024-25 and £3,070 in 2025-26 (frozen).
