Personal Allowance UK Explained: HMRC Tax Free Income Rules
The personal allowance UK is the amount of income individuals can earn before paying income tax. This allowance is set by HM Revenue & Customs (HMRC) and applies to most UK taxpayers.
The personal allowance is a key part of the UK tax system because it determines how much income remains tax-free each year. Once income exceeds this threshold, standard UK income tax rates apply.
What is the personal allowance in the UK?
The personal allowance UK represents the portion of annual income that is not subject to income tax.
For most taxpayers, the standard personal allowance is:
- £12,570 per year
This means the first £12,570 of income is tax-free for most individuals.
Official tax thresholds can be verified through the HMRC income tax guidance .
How personal allowance works
The personal allowance is usually applied automatically through the PAYE tax system for employees. Employers use the tax code provided by HMRC to calculate how much tax should be deducted from salary payments.
If the correct tax code is used, the personal allowance is spread across the year so that part of each paycheck remains tax-free.
When the personal allowance is reduced
The personal allowance UK may be reduced for high earners. Once annual income exceeds £100,000, the allowance gradually decreases.
For every £2 earned above £100,000, £1 of personal allowance is lost.
This means the allowance is completely removed once income reaches £125,140.
Personal allowance and tax codes
Tax codes determine how the personal allowance is applied to income. The most common tax code in the UK reflects the standard personal allowance.
If tax codes are incorrect, the allowance may not be applied properly. In those situations, taxpayers may overpay tax.

Key takeaway
The personal allowance UK allows individuals to earn a portion of income tax-free each year. For most taxpayers, this threshold is £12,570, although high earners may see their allowance reduced.
Understanding how the allowance works helps individuals manage their tax position and ensure they are not paying more tax than necessary.
