Bonus Tax Calculator UK
Bonus Tax Calculator UK is a financial tool that shows how much of your bonus you keep after UK tax deductions. In the United Kingdom, all bonuses are treated as income and taxed under the Pay As You Earn (PAYE) system, alongside your salary. This means your bonus is subject to Income Tax and National Insurance contributions at the same rates as regular earnings. Our calculator provides an instant breakdown based on your tax code, annual salary, and the bonus amount, so you can see the exact take-home pay. By using it, employees can plan ahead, avoid surprises, and understand how HMRC rules affect different bonus sizes—for example, a £5,000 bonus for a higher-rate taxpayer versus a basic-rate taxpayer.

Understanding Tax on Bonuses in the UK
In the UK, a bonus payment is not a separate, specially taxed item. Instead, it is simply added to your total income for the tax year. This is a crucial point for understanding how your bonus is taxed. Unlike some countries with special flat rates for bonuses, the UK system is progressive. This means your bonus could potentially push a portion of your income into a higher tax bracket.
Our Bonus Tax Calculator UK is built to account for this. It helps you accurately calculate tax on a bonus so you are fully prepared for how your payday will look.

Real-World Case Studies
To demonstrate the power of our calculator, let’s look at a couple of real-world scenarios.
Case Study 1: The Basic-Rate Taxpayer
Employee Profile: Sarah, a graphic designer, earns £30,000 annually.
Scenario: She receives a £2,000 performance bonus.
Without the Calculator: Sarah might assume she’ll get most of the £2,000.
With the Calculator: She enters her details and discovers her total income for the year is £32,000, which keeps her within the basic tax band. The calculator shows that she pays 20% Income Tax and 8% National Insurance on the bonus, leaving her with a take-home amount of approximately £1,440. This helps her realize the impact of deductions and plan her budget accordingly.
Case Study 2: The Higher-Rate Taxpayer
Employee Profile: David, a senior project manager, earns £48,000 annually.
Scenario: He receives a £5,000 bonus.
Without the Calculator: David might not realize that this bonus will push him into the higher tax bracket.
With the Calculator: The tool shows that his total income for the year is £53,000. The first £2,270 of his bonus is taxed at the 20% basic rate, while the remaining £2,730 is taxed at the 40% higher rate. The calculator provides a precise breakdown of his overall tax and National Insurance contributions, revealing that his take-home bonus is closer to £2,850.

FAQs: Bonus Tax Calculator UK
Do bonuses push me into a higher tax bracket? Yes, they can. Your bonus is added to your total income. If this combined figure exceeds a tax band threshold, the portion that crosses the threshold will be taxed at the higher rate.
Is my bonus taxed differently from my salary? No, it’s taxed in the same way. The key is that your bonus can increase your overall taxable income, which can change the effective tax rate applied to it.
What other deductions might apply? In addition to Income Tax and NI, our calculator includes options to factor in deductions for student loans, pension contributions, or salary sacrifice schemes.
