Most people look at one number on their payslip — the amount that hits their bank account — and ignore everything else. But every other line tells you something important about where your money is going and, crucially, where you might be able to keep more of it.

The anatomy of a UK payslip
A typical UK payslip has three sections:
- Earnings — what you're paid before deductions
- Deductions — tax, NI, pension, and other amounts taken off
- Net pay — what you actually receive
Let's go through each line.
Earnings section
Gross pay
Your total earnings before any deductions. This includes:
- Basic salary
- Overtime
- Bonuses
- Commission
- Statutory sick pay (SSP) or maternity/paternity pay if applicable
Gross pay is the starting point for all tax calculations. If you're on salary sacrifice, your gross pay on the payslip will already be reduced — that's intentional.
Salary sacrifice deductions (if applicable)
If you're in a salary sacrifice scheme (pension, cycle to work, EV), these appear as a reduction to gross pay — not as a deduction below it. This is why salary sacrifice saves NI as well as tax.
Deductions section
PAYE Income Tax
The amount of income tax deducted under Pay As You Earn. This is calculated based on:
- Your tax code (e.g. 1257L means a £12,570 Personal Allowance)
- Your taxable income (gross pay minus Personal Allowance)
- The tax bands for the year
If your tax code is wrong, you could be paying too much or too little tax. Common issues: emergency tax code (1257L W1/M1), wrong code after changing jobs, or not claiming Marriage Allowance. Check yours at gov.uk/check-income-tax.
National Insurance (NI)
Employee NI contributions for 2024/25:
- 0% on earnings up to £12,570/year (£1,047.50/month)
- 8% on earnings between £12,570 and £50,270/year
- 2% on earnings above £50,270/year
NI is calculated on your post-sacrifice gross pay — which is why salary sacrifice saves NI as well as income tax.
Pension contributions
If you're in a workplace pension, your contribution appears here. There are two types:
| Type | How it appears | Tax saving |
|---|---|---|
| Salary sacrifice | Reduces gross pay (above the line) | Tax + NI |
| Net pay arrangement | Deduction below gross | Tax only |
| Relief at source | Deduction below gross | Tax only (HMRC adds 20%) |
If your pension shows as a deduction below gross pay rather than reducing gross pay, you may be missing out on NI savings. Ask HR if salary sacrifice is available.
Student loan repayments
Deducted automatically if you're on Plan 1, 2, 4, or 5 and earning above the threshold:
| Plan | 2024/25 threshold | Rate |
|---|---|---|
| Plan 1 | £24,990/year | 9% above threshold |
| Plan 2 | £27,295/year | 9% above threshold |
| Plan 4 (Scotland) | £31,395/year | 9% above threshold |
| Plan 5 (new) | £25,000/year | 9% above threshold |
| Postgraduate | £21,000/year | 6% above threshold |
Other deductions
You may also see:
- Child maintenance (if a deduction from earnings order is in place)
- Court orders
- Season ticket loans (employer loans repaid from salary)
- Cycle to Work / EV scheme payments (if not salary sacrifice)
Net pay
Your take-home pay after all deductions. This is what hits your bank account.
Year-to-date (YTD) figures
Most payslips show cumulative totals for the tax year (April to April). These are useful for:
- Checking you haven't overpaid tax
- Verifying your P60 at year end
- Spotting if an emergency tax code was applied mid-year
Common payslip problems
| Problem | What to do |
|---|---|
| Emergency tax code (W1/M1) | Contact HMRC or your employer's payroll team |
| Wrong tax code | Check via Personal Tax Account at gov.uk |
| NI deducted on pension | Pension may not be salary sacrifice — ask HR |
| Student loan deducted but loan repaid | Contact Student Loans Company |
| No pension deduction | Check auto-enrolment status with HR |
How to pay less tax — starting from your payslip
Once you understand your payslip, you can identify savings:
- Increase pension sacrifice — reduces gross pay, saves tax + NI
- Add Cycle to Work — saves 28–42% on a new bike
- EV salary sacrifice — drive a new EV at 2% BiK rate
- Check your tax code — wrong codes are common after job changes
- Claim Marriage Allowance — worth £252/year if your partner earns under £12,570
