Estimate Your Net Pay, Bonus Impact, and Student Loan Repayments using our salary tax calculator.
Understanding your true take-home pay in the 2026/27 tax year requires more than just a simple salary calculation. With the Personal Allowance frozen at £12,570 and the National Insurance primary threshold remaining at £242 per week, “fiscal drag” means more of your income—especially bonuses—is subject to higher tax brackets.
This tool is designed for precision. Whether you are navigating the unique Scottish Tax Bands (including the Advanced and Top rates) or managing multiple Student Loan plans, this calculator provides a clinical breakdown of your monthly income. It specifically models the “Bonus Month” effect, showing you exactly how a one-off payment impacts your tax, NI, and pension contributions in a single pay period.
Key Features for 2026:
Pension Modeling: Adjust your contribution percentage to see the impact on your taxable pay.
Regional Accuracy: Supports the latest 2026/27 tax regimes for England, Wales, Northern Ireland, and Scotland.

The “60% Tax Trap”: Why Earners Between £100k and £125,140 are Hit Hardest
One of the most critical features of our 2026/27 Income Tax Calculator is its ability to model the “60% Tax Trap.” For many UK professionals, reaching a six-figure salary feels like a milestone, but the tax reality can be a shock.
In the UK, most individuals receive a Personal Allowance of £12,570, the amount you can earn before paying any Income Tax. However, once your “Adjusted Net Income” exceeds £100,000, this allowance is tapered away at a rate of £1 for every £2 you earn above that threshold.
The Mathematical Reality
If you receive a £1,000 pay rise or bonus when earning between £100,000 and £125,140:
- Income Tax: You pay 40% (£400) as a Higher Rate taxpayer.
- Loss of Allowance: Your tax-free Personal Allowance drops by £500.
- The “Hidden” Tax: That £500 of allowance is now taxable at 40%, costing you an extra £200 in tax.
Combined, you have paid £600 in tax on a £1,000 gain—an effective tax rate of 60%. This excludes National Insurance and Student Loan repayments, which can push the effective deduction even higher, sometimes exceeding 70%.
How to Beat the Trap
The most common strategy to mitigate this is through Pension Contributions. By “sacrificing” a portion of your salary or bonus into a SIPP or workplace pension, you reduce your Adjusted Net Income back toward the £100,000 mark. This effectively “buys back” your Personal Allowance, offering a massive 60% immediate ROI on your contribution.
