Understanding Your First Payslip UK 2026: What All the Deductions Mean

Receiving your first payslip is a milestone -- but it can also be a bit of a shock. The difference between the salary you agreed and the amount that actually lands in your bank account can feel alarming if you are not sure what is being deducted and why. This guide walks through every line on a typical UK payslip, using a worked example of someone earning GBP 25,000 per year in 2026/27.

Gross Pay

Gross pay is your salary before any deductions. If you agreed an annual salary of GBP 25,000, your monthly gross pay is GBP 25,000 divided by 12, which is GBP 2,083.33.

Some payslips also show any additional payments in gross pay, such as overtime, commission, bonuses or shift allowances. These are all counted as part of your gross earnings for tax purposes.

Income Tax: PAYE

PAYE stands for Pay As You Earn. It is the system HMRC uses to collect income tax directly from your wages, via your employer, before you are paid. Most employees never have to file a tax return because PAYE handles their tax automatically.

Your tax code determines how much of your earnings are tax-free before income tax kicks in. The most common code for 2026/27 is 1257L, which gives you the full Personal Allowance of GBP 12,570 per year -- or GBP 1,047.50 per month -- tax-free.

For our GBP 25,000 example:

• Personal Allowance: GBP 12,570 per year
• Taxable income: GBP 25,000 - GBP 12,570 = GBP 12,430
• Income tax at 20% (all within the basic rate band): GBP 2,486 per year
• Monthly income tax: GBP 207.17

If your tax code is different -- for example, you have a company benefit like a car or private medical insurance -- the taxable value of that benefit reduces your effective tax-free allowance, which is why some people have codes like 1157L or BR (basic rate on all pay).

National Insurance Contributions: Employee NI

National Insurance (NI) is a separate deduction from income tax, though both are collected by HMRC. Employee NI is charged at 8% on earnings between GBP 12,570 and GBP 50,270 (the Primary Threshold and Upper Earnings Limit for 2026/27). Earnings above GBP 50,270 attract only 2% employee NI.

For our GBP 25,000 example:

• Earnings above the Primary Threshold: GBP 25,000 - GBP 12,570 = GBP 12,430
• Employee NI at 8%: GBP 994.40 per year
• Monthly NI: GBP 82.87

NI contributions build up your qualifying years for the State Pension. You need 35 qualifying years to receive the full new State Pension, which is GBP 241.30 per week (GBP 12,548 per year) for 2026/27. If you are just starting work, every year you pay NI counts towards your eventual State Pension.

Pension Contributions

If your employer runs a workplace pension scheme under auto-enrolment, a contribution is deducted from your pay before you receive it. The legal minimum employee contribution is 5% of qualifying earnings (broadly, earnings between GBP 6,240 and GBP 50,270 per year). Your employer must contribute at least 3%.

Workplace pension contributions are usually taken from your gross pay before income tax is calculated (if you are in a salary sacrifice scheme) or deducted from net pay (in a relief-at-source scheme, where the pension provider claims the basic rate tax relief directly). Either way, pension contributions reduce your take-home pay but are one of the most tax-efficient ways to save.

For our GBP 25,000 example, 5% employee pension contribution:

• 5% of GBP 25,000 = GBP 1,250 per year
• Monthly pension contribution: GBP 104.17

Student Loan Repayments

If you studied for a degree starting from 2023 onwards, you are likely on Plan 5. Under Plan 5, you repay 9% of income above GBP 25,000 per year. If your salary is exactly GBP 25,000, you are right at the threshold and repayments would be negligible or nil in 2026/27.

If you were on an earlier plan -- Plan 1 (pre-2012 English/Welsh or Scottish students) or Plan 2 (2012 to 2022 English/Welsh students) -- the repayment threshold is different. Plan 2 has a threshold of GBP 27,295. At GBP 25,000, Plan 2 borrowers also pay nothing. Plan 1 has a lower threshold (GBP 24,990 for 2026/27), so a Plan 1 borrower on GBP 25,000 would pay a small amount: 9% of GBP 10 = GBP 0.90 per year.

Student loan deductions appear on your payslip separately from tax and NI.

Putting It All Together: The GBP 25,000 Example

Annual gross salary: GBP 25,000

• Income tax (PAYE): - GBP 2,486
• Employee NI: - GBP 994
• Pension (5%): - GBP 1,250
• Student Loan (Plan 5, at threshold): GBP 0

Net annual take-home: GBP 20,270 Net monthly take-home: GBP 1,689

Your employer also pays 15% employer NI on your earnings above GBP 5,000 (approximately GBP 3,000 per year at this salary level), but this does not appear on your payslip -- it is a cost your employer bears on top of your gross pay.

Other Things You Might See on Your Payslip

• Cumulative figures: Your payslip may show year-to-date totals for gross pay, tax and NI.
• Tax period: This tells you which tax week or month the payslip relates to. Tax week 1 is the first week of April.
• Emergency tax codes: If HMRC has not yet confirmed your tax code to your employer (common in a first job), you may be on an emergency code such as 1257L M1 or W1, which taxes you as if each pay period is independent. This can lead to over- or under-payment and is usually corrected automatically.
• Benefits in kind: If your employer provides non-cash benefits (gym membership, private healthcare), these may appear on your payslip but will not affect your take-home pay directly -- instead they affect your tax code.
