Understanding Your Salary After Tax: Gross Pay vs Take-Home Pay and Common Deductions

Understanding Your Salary After Tax: Gross vs Net and Common Deductions

When you see a job offer or a pay slip, two figures matter: your gross salary (the amount before deductions) and your take-home pay (what actually lands in your bank account). The difference between them is made up of several deductions that are required by law or chosen by you. This guide explains how your salary after tax is calculated for the 2026/27 tax year, covering Income Tax, National Insurance, pension contributions, and student loan repayments.

Gross Salary vs Take-Home Pay

Your gross salary is the headline figure – the annual amount your employer agrees to pay you. But you never receive that full amount. Your employer uses the PAYE (Pay As You Earn) system to deduct:

• Income Tax – based on your taxable income after the Personal Allowance.
• National Insurance – calculated separately on your earnings.
• Pension contributions – if you are enrolled in a workplace pension (automatic enrolment).
• Student loan repayments – if you have an outstanding loan and earn above the threshold.

What remains is your net pay or take-home pay. For example, on the UK median full-time gross salary of £39,039 (ONS ASHE, April 2025), the typical take-home pay after Income Tax and National Insurance is about £31,628 per year – that is £2,636 per month. The government takes £7,411, an effective rate of 19%.

Income Tax: How It Works

For the 2026/27 tax year, everyone in England, Wales and Northern Ireland receives a Personal Allowance of £12,570. This is the amount you can earn before paying any Income Tax. Income above that is taxed at:

• Basic rate: 20% on earnings from £12,571 to £50,270
• Higher rate: 40% on earnings from £50,271 to £125,140
• Additional rate: 45% on earnings above £125,140

Your tax code (usually 1257L) tells your employer how much tax-free pay to give you. If you have a different code – for example, because of benefits in kind or underpaid tax from a previous year – your take-home pay will change.

Scottish Income Tax

Scotland sets its own Income Tax bands and rates. For 2026/27, the bands are:

• Starter rate: 19% on £12,571–£15,397
• Basic rate: 20% on £15,398–£27,491
• Intermediate rate: 21% on £27,492–£43,662
• Higher rate: 42% on £43,663–£75,000
• Advanced rate: 45% on £75,001–£125,140
• Top rate: 48% on earnings above £125,140

National Insurance is the same across the UK, but the different Income Tax bands mean that Scottish taxpayers on higher incomes (above about £43,660) pay more Income Tax than those in the rest of the UK.

National Insurance Contributions

Employee National Insurance (NI) is a separate deduction from Income Tax. For 2026/27, the rates are:

• 0% on earnings up to £12,570
• 8% on earnings between £12,571 and £50,270
• 2% on earnings above £50,270

NI is calculated on your gross earnings (before pension deductions if you use salary sacrifice). It is UK-wide, so the same rates apply in Scotland. For most people earning between £20,000 and £50,000, NI is the second-largest deduction after Income Tax.

Pension Contributions

If you are enrolled in a workplace pension, your employer will deduct your contribution from your gross pay. Many schemes use salary sacrifice, where you agree to give up some gross salary in exchange for the employer paying that amount into your pension. This reduces your taxable income and your NI, meaning you pay less tax and NI overall. Your take-home pay will be lower than your gross salary, but you are building retirement savings.

Student Loan Repayments

If you have a student loan, repayments are deducted through PAYE once your income exceeds the threshold for your plan. The thresholds for 2026/27 are:

• Plan 1: £26,900 per year, 9% of income above that
• Plan 2: £29,385 per year, 9%
• Plan 4 (Scotland): £33,795 per year, 9%
• Plan 5: £25,000 per year, 9%
• Postgraduate Loan: £21,000 per year, 6%

Repayments are based on your annual income, not monthly, so if your income varies, your monthly deductions may be adjusted at the end of the tax year.

Example: £35,000 Salary Breakdown

For a single person in England with no pension and no student loan, on a gross salary of £35,000:

• Income Tax: £4,486 (20% of £22,430 above the Personal Allowance)
• National Insurance: £1,794.40 (8% of £22,430)
• Take-home pay: £28,719.60 per year (£2,393.30 per month)

That means you keep about 82p of every £1 you earn, and 17.9% goes in tax and NI.

Key Takeaways

• Your salary after tax is always lower than your gross salary due to Income Tax, NI, and possibly pension and student loan deductions.
• The Personal Allowance of £12,570 means you pay no Income Tax on the first part of your earnings.
• National Insurance is a separate charge that funds state benefits.
• Scotland has different Income Tax bands that can significantly affect your take-home pay, especially on higher incomes.
• Pension contributions (especially via salary sacrifice) can reduce your tax and NI bill, increasing your net effective pay.
• Always check your payslip and official GOV.UK guidance for your specific circumstances, as tax codes and deductions can vary.
