The UK Income Tax system is a progressive tax structure where different portions of your income are taxed at increasing rates. For the 2026/27 fiscal year, several key thresholds remain critical for every taxpayer to understand.
The standard Personal Allowance for the 2026/27 tax year is £12,570. This is the amount of income you can receive each year without paying any Income Tax. If you earn less than this, you typically pay no tax at all. Note that this allowance is reduced by £1 for every £2 of 'adjusted net income' above £100,000.
The Basic Rate of 20% applies to taxable income between £12,571 and £50,270. Most UK workers fall into this category for the majority of their earnings.
The Higher Rate of 40% is applied to income between £50,271 and £125,140. When you enter this band, it's important to consider tax-efficient strategies such as increased pension contributions or Gift Aid donations which can effectively extend your basic rate band.
The Additional Rate of 45% applies to all taxable income over £125,140. At this level, the Personal Allowance has been completely tapered away.
