Before you start
This works best around the kitchen table after dinner, with the child genuinely curious rather than dragged. Aim for one focused sitting; don't try to teach tax in chunks across a week.
You will need:
- One of your real payslips (redact the actual amount if you want — the categories and ratios are what matter), OR the example payslip in the next page
- 10 £1 coins, or 10 paper "pretend pounds" cut from notepaper
- A pen and a piece of paper
- Optional: a quick scroll through the news or gov.uk so you can show real numbers if asked
1What does tax pay for?6 min
Start with what they already see.
"When grown-ups earn money, the government takes a small portion as tax. That tax pays for things we all share. Can you guess some of them?"
They'll typically think of:
- NHS hospitals and GPs
- Schools and teachers
- Roads and pavements
- Bins and parks
- Police and firefighters
Add a few they probably won't:
- The army and navy
- State pensions for older people
- Libraries
- Free buses for older people and disabled people
(There's no quick answer. The point of the question is to make tax feel like the price of sharing.)
2Coin demonstration — how much tax is it?8 min
The single most useful tax demo for under-11s. Stack of 10 £1 coins. Each coin = 10% of someone's wage.
Start with all 10 coins in front of the child. Tell them this is one month of a grown-up's wage — £100 (or however many coins you have).
Take coins away as you talk:
- Take 1.5 coins (move 15p worth aside). "This is Income Tax. About 15p out of every £1 of wage goes to the government."
- Take half a coin. "This is National Insurance. About 5p out of every £1 also goes to the government, but for a different reason — it pays for the State Pension and helps if a grown-up loses their job or gets ill."
- Take 1 coin. "This is the workplace pension — saving for when the grown-up is old."
- Keep 7 coins. "This is what actually lands in the bank account. Out of every £10, about £7 reaches the family. The rest goes to tax, NI and saving for old age."
This is a values question. Reasonable people disagree.
3The Personal Allowance — tax-free zone5 min
Bigger idea, but 9-11 year-olds can grasp it.
"The first £12,570 a grown-up earns each year is tax-free. That's called the Personal Allowance. The government decided everyone needs that much money before tax even starts."
"£12,570 a year is just over £1,000 a month. So if a grown-up earns less than £1,000 a month, they pay no Income Tax at all."
(£15,000 − £12,570 = £2,430 of taxed income.) Work it out together. At 20% that's £486 tax for the year — about £40 a month.
4Looking at a real payslip8 min
Now the abstract becomes concrete.
Don't skip this step. The lesson lands far harder with a real document than with talking about one.
| Line | What it shows |
|---|---|
| Gross pay | Total before anything is taken off — the "salary" |
| Tax code | Usually 1257L for most people — the £12,570 tax-free part |
| Income Tax | The 20% (or 40% for high earners) taken on top of the allowance |
| National Insurance | Around 8% taken on top — for State Pension and benefits |
| Pension | The grown-up's saving for old age, often 5% from them + 3% from work |
| Net pay | What actually lands in the bank |
Let the child do the maths if they want: "if the gross is X and the tax is Y, what's the percentage?" 9-11 year-olds can usually do this with a calculator.
5Closing — what tax means3 min
Wrap up by checking understanding without making it feel like a test.
The second question is the more useful one. There's no right answer. The point: tax decisions are choices, and they're democratic.
"When you're older and you start working, this is going to be on your payslip too. Now you know what it all means."
After the conversation
Follow-up over the next week:
- Show them an actual news story about tax (Budget Day in spring, or any tax-related headline). Watch their eyes light up when they recognise terms.
- If they're curious, look up the basic Income Tax rates on gov.uk/income-tax-rates together. The official rates page is short and readable.
- Mention NI when they get their National Insurance number around age 16 — "remember that conversation we had? This is the number."
