How UK Tax Calculations Work
Income Tax
Income tax is calculated on your taxable income (gross salary minus Personal Allowance and any salary sacrifice deductions). For 2025/26, the rates are:
| Band | England/Wales/NI Taxable Income | Rate | Scotland Taxable Income | Rate |
|---|---|---|---|---|
| Personal Allowance | Up to £12,570 | 0% | Up to £12,570 | 0% |
| Starter Rate | – | – | £12,571 – £15,397 | 19% |
| Basic Rate | £12,571 – £50,270 | 20% | £15,398 – £27,491 | 20% |
| Intermediate Rate | – | – | £27,492 – £43,662 | 21% |
| Higher Rate | £50,271 – £125,140 | 40% | £43,663 – £75,000 | 42% |
| Advanced Rate | – | – | £75,001 – £125,140 | 45% |
| Additional/Top Rate | Over £125,140 | 45% | Over £125,140 | 48% |
National Insurance Contributions
Employees pay Class 1 National Insurance on earnings above £12,570 per year (£242/week). The rate is 8% on earnings between £12,570 and £50,270, then 2% on earnings above £50,270.
Student Loan Repayments
Repayments are calculated based on your income above the threshold for your plan type. The 2025/26 thresholds are:
- Plan 1: £26,065 threshold, 9% repayment rate
- Plan 2: £28,470 threshold, 9% repayment rate
- Plan 4: £31,395 threshold, 9% repayment rate
- Plan 5: £25,000 threshold, 9% repayment rate
- Postgraduate: £21,000 threshold, 6% repayment rate
Pension Contributions
Salary sacrifice schemes deduct pension contributions before tax and NI, reducing your taxable income. Relief at source means contributions are taken after tax, but you receive 20% tax relief automatically, with higher/additional rate taxpayers claiming extra relief through self-assessment.
Regional Tax Differences
Scotland vs Rest of UK
Scotland has devolved powers over income tax rates and bands, resulting in a more progressive tax system with five bands instead of three. While the Personal Allowance remains the same across the UK (£12,570), Scottish taxpayers face different rates once they earn above this threshold.
For someone earning £30,000, a Scottish taxpayer pays approximately £60 more in income tax annually compared to someone in England. However, at £50,000, the difference increases to around £1,552 more in Scotland. At higher incomes (£75,000+), Scottish taxpayers can pay significantly more due to the 42% and 45% rates kicking in at lower thresholds.
Wales and Northern Ireland
Wales and Northern Ireland currently follow the same income tax rates and bands as England. Wales has the power to vary rates but has chosen not to exercise this since gaining the authority in 2019.
Frequently Asked Questions
What is a tax code and where can I find mine?
Your tax code tells your employer how much tax-free income you’re entitled to in that tax year. It appears on your payslip, P60, or PAYE coding notice from HMRC. The most common code for 2025/26 is 1257L, which gives you the standard Personal Allowance of £12,570. Codes can vary if you have multiple jobs, receive benefits, or owe tax from previous years.
Why is my actual take-home pay different from the calculator?
Several factors can cause variations: emergency tax codes when starting a new job, unpaid tax from previous years being collected through your code, company benefits like car allowances or private medical insurance, court-ordered deductions, or errors in your tax code. Always check your payslip details and contact HMRC if something seems incorrect.
When do I stop paying National Insurance?
You stop paying employee National Insurance contributions when you reach State Pension age, even if you continue working. For people born after 6 April 1978, this is currently age 67. However, your employer still pays employer NICs on your wages. Tick the “No National Insurance” box if this applies to you.
How does salary sacrifice affect my take-home pay?
Salary sacrifice for pensions reduces your gross salary before tax and National Insurance are calculated, lowering both deductions. For example, sacrificing 5% of a £30,000 salary (£1,500) saves you £300 in tax and £120 in NI (total £420), meaning your net cost is only £1,080 for £1,500 of pension savings. This is more beneficial than relief at source, where you only save the tax portion.
Can I repay student loans from multiple plans simultaneously?
Yes, if you have both an undergraduate and postgraduate loan, you’ll repay both simultaneously once you earn above each plan’s threshold. The deductions are calculated separately and added together. This calculator currently handles one plan at a time, so calculate each separately and add the totals if you have multiple loans.
What is the Marriage Allowance?
Marriage Allowance lets you transfer £1,260 of your Personal Allowance to your spouse or civil partner if they earn more than you. The lower earner must earn less than £12,570, and the higher earner must be a basic rate taxpayer. This can save up to £252 per year in tax (£1,260 × 20%).
Do I pay tax on my bonus?
Yes, bonuses are taxed as regular income. They’re added to your salary and taxed at your marginal rate. If your bonus pushes you into a higher tax band, the portion in the higher band is taxed at that rate. You’ll also pay National Insurance on bonuses. Some employers spread bonuses across the year, while others pay them as a lump sum, which can affect monthly deductions.
What happens to my Personal Allowance if I earn over £100,000?
Your Personal Allowance reduces by £1 for every £2 you earn over £100,000. It disappears completely at £125,140. This creates an effective tax rate of 60% on income between £100,000 and £125,140 (40% income tax plus the loss of 20% tax relief on the allowance). Many high earners make additional pension contributions to stay below £100,000 and retain their allowance.
Tax Planning Strategies
Maximise Pension Contributions
Increasing pension contributions through salary sacrifice is one of the most tax-efficient strategies. Every £1 contributed via salary sacrifice to someone earning £30,000 costs them only 72p (saving 20% tax and 8% NI). Higher rate taxpayers save even more – 48p per £1 for those paying 40% tax.
Utilise Childcare Vouchers
If you joined a childcare voucher scheme before it closed to new entrants in October 2018, you can still benefit. The amount of tax and NI relief depends on your tax band, potentially saving up to £1,196 per year for basic rate taxpayers.
Check Your Tax Code Annually
HMRC estimates that millions of people pay the wrong amount of tax each year due to incorrect tax codes. Review yours every April and after changing jobs. If you’ve overpaid, you can claim back up to four years’ worth of tax.
Consider the £100,000 Threshold
If you earn close to £100,000, consider whether pension contributions, charitable donations (Gift Aid), or salary sacrifice schemes could keep you below this threshold and preserve your full Personal Allowance.
Common Calculation Errors
Forgetting Scottish Tax Rates
Scottish residents often use calculators with English tax rates, underestimating their liability. Always select the correct region in this calculator to get accurate results.
Misunderstanding Pension Relief Methods
Confusing salary sacrifice with relief at source leads to incorrect calculations. Salary sacrifice reduces gross pay before tax; relief at source takes contributions from net pay and HMRC adds 20% automatically.
Incorrect Student Loan Plan
Using the wrong student loan plan dramatically affects repayment amounts. Plan 2 has a £2,405 higher threshold than Plan 5, meaning someone earning £30,000 would repay £216 more annually on Plan 5.
Not Accounting for Loss of Personal Allowance
High earners between £100,000-£125,140 often underestimate their tax because they don’t account for the tapering of the Personal Allowance, creating a 60% marginal rate.
Overlooking National Insurance Upper Limit
While income tax continues at 40% or 45%, National Insurance drops to 2% above £50,270. This significantly affects the marginal rate of deductions on higher salaries.
