What this guide covers

Children pay tax the same way as adults. There's no special "kids' pass". Most 14-16 year-olds owe £0 only because they earn under £12,570. Your savings interest is normally tax-free under the Personal Savings Allowance, but the £100 parental rule can drag some interest back into your parent's tax. Junior ISA interest is always tax-free.

①Myth 1: "Kids don't pay tax"

UK tax law doesn't care about your age. The system is the same whether you're 6 or 60:

Personal Allowance: £12,570 a year (2026/27, frozen)
Basic rate of Income Tax: 20% on earnings £12,571 – £50,270
Higher rate: 40% on earnings above £50,270 (Scotland has different bands)

Why most teenagers pay £0: a Saturday-job income of £3,000-£4,000 a year is comfortably under £12,570. Not because they're a child, but because they're a low earner.

If a 16-year-old earned £20,000 (e.g. as a full-time apprentice), they'd pay tax exactly like a 30-year-old on £20,000:

First £12,570 — tax-free
Next £7,430 — taxed at 20% = £1,486 Income Tax
NI also kicks in on weekly earnings over £242

②Myth 2: "Savings interest is always tax-free for kids"

Mostly true in practice, but the rules are subtler than people think.

Every UK saver gets a Personal Savings Allowance (PSA) on top of the Personal Allowance:

Basic-rate taxpayers (most teens, if they earn at all): £1,000 of savings interest tax-free
Higher-rate taxpayers: £500
Additional-rate taxpayers: £0

At 4% interest, you'd need £25,000 in savings to earn £1,000 a year of interest. Most teenagers have nowhere near that, so 0% tax on savings is the normal outcome.

Junior ISA interest is always tax-free, regardless of how much. JISAs have a £9,000/year contribution limit (2026/27) and are locked until you're 18.

③Myth 3: "Gifts from parents are tax-free"

Mostly true, with one trap.

Cash gifts from parents and grandparents are not taxable income for you. There's no "gift tax" in the UK in the way other countries have. (There's Inheritance Tax on someone's estate when they die, but that's not the same thing.)

The trap: the £100 parental rule. If a parent gives you cash, and you put it in a savings account that earns interest, any interest over £100/year is treated as the parent's income for tax purposes — not yours.

Scenario	Who is taxed?
Parent gives £500. Interest £20.	Tax-free (under £100)
Parent gives £3,000. Interest £120.	The whole £120 is added to the parent's taxable income
Grandparent gives £3,000. Interest £120.	Tax-free for you (£100 rule only applies to parents)
Parent contributes to a Junior ISA: £3,000. Interest £120.	Tax-free (JISAs are completely outside the £100 rule)

So if a parent wants to gift you a significant lump sum, the tax-efficient route is a Junior ISA. Outside the JISA, the £100 trap applies.

④When you might owe tax — three real scenarios

You worked a high-paying summer job and earned more than £12,570 in one tax year (uncommon but possible — modelling, film work, social media earnings). You owe Income Tax on the excess.
You're an apprentice on £18,000+/year. You'll pay Income Tax + NI like any other employee, deducted at source by your employer.
You earn money from a side hustle (selling things on Vinted, doing tutoring on UrbanSitter, streaming, content creation): you have a £1,000 Trading Allowance. Earnings under £1,000/year don't need to be declared. Above £1,000, you should file a Self Assessment tax return.

Self Assessment under 18. Yes, you can file a tax return as an under-18. HMRC doesn't mind your age. You'll need an NI number (you'll have one by 16) and a Government Gateway login. It's annoying but legal and necessary if your side income passes £1,000 in a year.

⑤How to claim back overpaid tax

If you've had tax deducted from your wages by mistake — for example, your first employer put you on emergency code BR — you can claim it back.

If you're still in the same job: HMRC almost always refunds it through your payroll within a few weeks once your tax code is corrected. Phone HMRC on 0300 200 3300 to nudge them.
If you've left the job mid-year: after 6 April you can file a P50 form (online or by post) to claim back overpaid tax. Refund usually arrives within 3 weeks.
End-of-tax-year reconciliation: HMRC checks all your jobs against the Personal Allowance and sends a P800 letter if you're owed money. Usually arrives in autumn.

You've got four years to claim back overpaid tax. Don't leave money with HMRC if it's yours.

Watch for refund scams. HMRC never texts or emails you offering a tax refund. Anyone who does is a scammer. Real refunds come via P800 letter or appear in your payslip — not via "click this link" texts.
