Before you start
Have this conversation within a week of their first paycheck landing, not in the abstract before. The actual payslip in front of them makes everything stick.
You will need:
- Their first payslip (printed or on their phone — printed works better)
- Their bank app or online banking, logged in
- This pack printed or open on a laptop
- A pen and notepaper for the budget
- If applicable: details of any board contribution you'd expect
1Set the tone3 min
This is a milestone moment. Treat it like one.
"First paycheck is a big deal. Let's spend half an hour walking through what every line of this means and setting up a few habits that will save you a lot of stress later."
Don't go in with the budget already decided. The conversation has more weight if some decisions are theirs.
2Walk through the payslip line by line12 min
Take each line slowly. Even the boring ones.
"This is the headline number — what your hourly rate × hours adds up to before anything comes off. Does it match what you expected?"
"This says you get £12,570 of tax-free allowance per year. 1257L is standard. If yours shows BR, 0T or anything with W1/M1 at the end — that's emergency tax and we need to phone HMRC."
"20% of everything you earn above £12,570 a year. At your current rate, you might not pay any tax for the first few months — you're under the threshold."
"8% of weekly pay above £242. Pays for your future State Pension and unemployment benefits. NI category should be 'A' for most people. Apprentices under 25 use 'H'."
"Auto-enrolment kicks in at 22 and £10,000/year. If you're younger and earning over the threshold, you can ask to join — and your employer must let you, with the same contributions. That's free money."
"What actually lands in your bank account. Check it matches what you got."
| If this line shows... | Do this |
|---|---|
| Tax code BR / 0T | Phone HMRC 0300 200 3300 — usually corrects within a payslip or two |
| NI category not A / H | Ask payroll: "what category am I and why?" |
| Net pay doesn't match your bank | Ring payroll same day — they fix mistakes quickly |
| No NI deducted | Probably under the £242/week threshold — normal |
3Set up automatic savings on payday6 min
This is the most valuable habit anyone can build in their first job year.
"Save before you spend, not after. If you wait until end of month, the money's usually gone. If you transfer to savings the day after pay lands, it's out before you decide."
Set up a standing order from current account to a savings account for the day after their normal payday.
Aim for 20% of net pay as a default. £20 from a £100 paycheck. £40 from £200. They can always increase. Starting too high and failing is worse than starting low and succeeding.
For a 15-17 year-old, a teen current account's linked savings space (Halifax, Nationwide, Monzo, Starling all have these) works fine. For 16+ with a regular work pattern, a Cash JISA at competitive rate makes more sense — tax-free, FSCS protected.
4The board conversation7 min
If you expect them to contribute to household costs ("board"), this is the moment.
"Now that you're earning, I'd like us to talk about board. I don't need the money — this isn't about that. It's about you practising how it feels to have a direct debit going out. £30 a month, fixed. You'll pay 10x that in real rent within 3 years. Better to start the habit now than have it shock you at 18."
Some families do board, some don't. There's no right answer. The conversation matters more than the amount.
| Income | Suggested board (if collected) |
|---|---|
| £80/month part-time | £0 (savings habit matters more) |
| £200/month Saturday job | £20 if at all |
| £500+/month apprentice | £50-100 — closer to real rent ratios |
| £1,200/month full-time | £150-250 — depends on family situation |
5The take-home split5 min
The 50/30/20 starter rule, adapted to teen reality.
- Save — the standing order you just set up
- Fixed — phone bill, bus pass, board, Spotify — the things that come out automatically every month
- Spend — whatever's left, no rules
For their actual paycheck, fill in the three numbers. £200 example: £40 save, £40 fixed, £120 spend.
"Whatever's in spend, you choose. I'm not going to ask. Want to blow it on a concert ticket? Up to you. Want to save another £50 on top? Up to you. The point of the system is the save and fixed are dealt with first."
6Closing — what changes from here2 min
Wrap up by naming what's different from a week ago.
"From this month on, three things happen automatically: tax and NI come off at payroll, your savings transfer happens the day after pay, and your fixed bills go out. What's left is genuinely yours."
After the conversation
Schedule a 10-minute check-in 3 months from now:
- Is the savings standing order still going out? (Easy to cancel under stress.)
- Is the tax code right by month 3? (Emergency codes usually sort themselves by then.)
- Has anything come up that surprised them?
If they're approaching 18, plan the LISA conversation next — see the 18th-birthday handover pack.
