Your First Payslip: Explained
Gross pay, tax code, National Insurance, and pension auto-enrolment — what it all means, and where your money actually goes.
Last updated: September 2026
Quick answer
Your payslip shows gross pay (what you earned before deductions) and net pay (what actually lands in your bank account). Most people don't pay any Income Tax on the first £12,570 they earn in a tax year — after that, Income Tax and National Insurance are deducted automatically, and a small pension contribution may be too, if you're over 22 and earning above £10,000 a year.
Getting your first payslip can feel like reading a different language — tax codes, deductions, and numbers that don't match what you were told your wage would be. Here's what each part actually means, in plain English.
Gross pay vs net pay
Gross pay is your total earnings before anything is taken off — this is usually the number mentioned when a job is advertised, or the hourly rate you agreed to. Net pay (sometimes called "take-home pay") is what's actually paid into your bank account, after tax, National Insurance, and any pension contribution have been deducted. The gap between the two is completely normal — it's not a mistake or your employer keeping money back unfairly.
Worked example — £16,000 a year, standard tax code
Gross pay (annual)£16,000
Income Tax (20% on income above £12,570)−£686
National Insurance (8% on income above £12,570)−£274
Net pay (annual)£15,040
Figures based on 2026/27 tax rates and thresholds, standard tax code, no pension contribution in this example. Real payslips vary by tax code and personal circumstances — this is illustrative, not a substitute for checking your own payslip.
What's a tax code?
Your tax code tells your employer how much of your pay is tax-free before Income Tax starts being deducted. Most people with one job and no unusual circumstances have the code 1257L for 2026/27 — the "1257" represents the £12,570 tax-free Personal Allowance, and "L" means the standard allowance applies. If your tax code looks different, it's worth checking why with HMRC directly, since an incorrect code can mean paying too much or too little tax.
Income Tax and National Insurance — what's actually being taken
| Deduction | Rate | Applies to |
|---|
| Income Tax | 0% | First £12,570 of annual income |
| Income Tax | 20% (basic rate) | Income between £12,570 and £50,270 |
| National Insurance | 0% | First £12,570 of annual income |
| National Insurance | 8% | Income between £12,570 and £50,270 |
2026/27 rates for a standard employee. Most first jobs and part-time work fall entirely within the basic rate band above — higher rates only apply well above £50,270.
Pension auto-enrolment — the bit most first payslips don't have yet
If you're 22 or over and earning more than £10,000 a year from one employer, you'll usually be automatically enrolled into a workplace pension, with a small percentage of your pay contributed automatically — currently a minimum of 5% from you and 3% from your employer on qualifying earnings. If you're younger than 22, or earning under £10,000, you likely won't see this yet, but you often have the right to opt in voluntarily even below the threshold.
"Pay yourself first" — a simple habit worth starting early
One of the most repeated ideas across personal finance writing is surprisingly simple: decide how much you want to save before you spend anything, rather than saving whatever happens to be left at the end of the month. Even a fixed 10% of your net pay, moved to savings the moment you're paid, builds a habit that gets harder to start the later you leave it. It doesn't need to be complicated — a standing order to a separate savings account on payday is enough.
What's next after your first job?
Once you're earning and saving, a full bank account and eventually a Stocks & Shares ISA are the natural next steps. See how the accounts compare.

Frequently asked questions
Why is my pay lower than the hourly rate I was told?
The rate you were quoted is almost always gross pay, before Income Tax, National Insurance, and any pension contribution are deducted. What lands in your bank account is your net pay, which will be lower — this is normal, not an error.
Do I pay tax on my very first job?
Only on income above £12,570 in a tax year (2026/27). If your total earnings for the year stay below that, you shouldn't pay Income Tax at all — though National Insurance and tax can still be deducted per pay period even if your total for the year ends up below the threshold, and may be refundable.
What if my tax code looks wrong?
Contact HMRC directly to check — an incorrect tax code can mean you're paying too much or too little tax without realising, and it's usually a quick fix once flagged.
Can I opt in to a pension before I'm automatically enrolled?
Often yes, even below the usual age or earnings threshold — ask your employer directly, since the right to opt in varies by scheme.
