What is a Personal Tax Allowance?


A Personal Tax Allowance, also known as a tax-free allowance or a personal allowance, is the amount of income that an individual can earn before they are required to pay taxes. It is a tax-free amount that everyone is entitled to, and it is adjusted annually by the government to keep up with inflation and changes in the economy.


The purpose of the Personal Tax Allowance is to ensure that individuals with low incomes are not burdened by income taxes, allowing them to meet their basic needs without having to pay taxes. It serves as a way to provide a certain level of financial support to those with lower incomes, helping to reduce income inequality and provide relief to individuals who would otherwise struggle to make ends meet.

Changes in Personal Tax Allowance

Historical Overview

The Personal Tax Allowance has undergone various changes throughout history. In the past, it was significantly lower than it is today, meaning that a larger portion of people’s income was subject to taxation. Over the years, the government has gradually increased the allowance to provide individuals with more tax relief and to reflect changes in the cost of living.

Current Rates

As of the 2021/2022 tax year, the Personal Tax Allowance in the UK is £12,570. This means that individuals can earn up to this amount before they are required to pay income tax. It is worth noting that the Personal Tax Allowance may be reduced for individuals with higher incomes, in what is known as the “income limit reduction.”

Calculation of Personal Tax Allowance

Determining Factors

The calculation of an individual’s Personal Tax Allowance takes into account various factors. The primary factor is the individual’s annual income. If an individual’s income exceeds the income limit reduction threshold, their Personal Tax Allowance will be reduced. Other factors, such as age and certain tax reliefs or deductions, can also impact the calculation of the allowance.

Limits and Thresholds

The income limit reduction threshold for the 2021/2022 tax year is £100,000. If an individual’s income exceeds this threshold, their Personal Tax Allowance will be reduced by £1 for every £2 of income above the threshold. Once an individual’s income reaches £125,140, their Personal Tax Allowance is reduced to zero.

Impact of Personal Tax Allowance

On Individuals

The Personal Tax Allowance has a substantial impact on individuals, especially those with lower incomes. It provides them with a significant amount of tax relief, allowing them to retain more of their hard-earned income. This can help alleviate financial pressure and assist individuals in meeting their essential living expenses.

On Businesses

The impact of the Personal Tax Allowance on businesses is indirect. By providing individuals with more disposable income, the allowance can potentially stimulate consumer spending and boost the economy. Increased consumer spending can benefit businesses by increasing demand for goods and services, leading to potential growth opportunities.

Claiming Personal Tax Allowance


Individuals are generally eligible for the Personal Tax Allowance if they are a resident in the UK for tax purposes. Non-residents may also be eligible in certain circumstances. There are no age restrictions for claiming the allowance, making it available to both working individuals and retirees.

Application Process

The Personal Tax Allowance is usually automatically applied when individuals receive their income, such as through their employer’s payroll system. However, it is essential for individuals to ensure that their income is correctly reported to the tax authorities to receive the full benefit of the allowance. Individuals can also make adjustments to their tax codes if necessary, to ensure accurate calculations of their Personal Tax Allowance.

Personal Tax Allowance vs. Tax Credits


While the Personal Tax Allowance and tax credits are both forms of tax relief, they serve different purposes and work differently. The Personal Tax Allowance is a deduction from an individual’s taxable income, reducing the amount of income that is subject to taxation. Tax credits, on the other hand, are payments made by the government to individuals or families with lower incomes to provide financial support.


The Personal Tax Allowance and tax credits can interact in certain situations. Tax credits are calculated based on an individual’s income after their Personal Tax Allowance has been applied. Individuals with higher incomes or whose Personal Tax Allowance has been reduced may receive lower tax credits or may not be eligible for certain tax credit programs.

Married Couple’s Allowance


In addition to the Personal Tax Allowance, married couples and those in civil partnerships may be eligible for the Married Couple’s Allowance. This allowance is designed to provide additional tax relief to couples where at least one spouse was born before April 6, 1935.

Eligibility Criteria

To be eligible for the Married Couple’s Allowance, at least one spouse must have been born before April 6, 1935. The allowance amount depends on the income and age of the older spouse. The allowance is transferable between spouses, allowing a portion of the older spouse’s allowance to be allocated to the partner with the higher income.

Effects of Tax Allowance Changes on Income

Income Tax Calculation

Changes in the Personal Tax Allowance can have a significant impact on an individual’s income tax calculation. An increase in the allowance would reduce the taxable income, resulting in a lower overall tax liability. Conversely, a decrease in the allowance would increase the taxable income and potentially lead to a higher tax liability.

Other Tax Obligations

It is important to note that the Personal Tax Allowance only applies to income tax. Other forms of taxation, such as National Insurance contributions or capital gains tax, have separate rules and thresholds. Individuals should be aware of their entire tax obligations and consider all aspects of their financial situation when planning their tax affairs.

Understanding Tax Coding Notices


Tax coding notices are sent to individuals by HM Revenue and Customs (HMRC) to inform them of their tax code. The tax code determines how much income an individual can earn before they start paying income tax and whether any other adjustments or deductions should apply.


Tax coding notices typically include information such as the individual’s tax code, their Personal Allowance, any reductions to the allowance, and any other special tax reliefs or deductions that may apply. It is important for individuals to review their tax coding notices carefully and contact HMRC if they believe there are any errors or discrepancies.

FAQs about UK Personal Tax Allowance

What happens if my income exceeds the tax allowance?

If your income exceeds the tax allowance, you will be required to pay income tax on the amount that exceeds the allowance. The tax rate applied will depend on your income level and tax brackets.

Can I transfer my unused allowance to my spouse?

Yes, the Personal Allowance can be transferred between spouses in certain circumstances. However, if you or your spouse are eligible for the Married Couple’s Allowance, you cannot transfer personal allowance between spouses.

The FAQs listed above are just a few examples of commonly asked questions about the UK Personal Tax Allowance. It is important for individuals to seek professional advice or refer to the official guidance provided by HMRC for specific and personalized information regarding their tax situation.

In conclusion, the Personal Tax Allowance is a vital aspect of the UK’s taxation system, providing individuals with tax relief that helps support their financial well-being. Understanding how the allowance is calculated, its impact on income, and how to claim it correctly is crucial for individuals to ensure they are benefiting from this important tax benefit.
