Big Question: Is tax a loss or an investment in society?

Main Theme: Tax is not money taken from you, it is money you invest in the society you live in. The roads, schools, hospitals and emergency services that make daily life possible exist because everyone contributes.

Session objectives

  • State what tax is and name the four main UK taxes: Income Tax, National Insurance, VAT and Corporation Tax.
  • Explain how progressive Income Tax works, and calculate the tax on a simple salary using the Personal Allowance and tax bands.
  • Explain the difference between PAYE and Self Assessment.
  • Identify the main areas of UK public spending and their approximate scale, and evaluate the trade-offs in allocating a budget.
  • Justify, using evidence, whether tax is a loss or an investment in society.

Misconceptions to watch for

  • Tax is just money the government takes off you, and you get nothing back.

    Tax pays for things most people use every day, such as the NHS, schools, roads, bin collections and the emergency services. Not everyone gets back exactly what they pay in, but it isn't money that disappears.

  • Everyone pays the same percentage of tax.

    Income Tax is progressive. The first slice of income, the Personal Allowance, is tax-free, and each higher rate only applies to the slice of income in that band. So lower earners pay a smaller share of their income overall.

If a student asks…

Isn't the NHS free?
It's free when you use it, but it's paid for by tax. Everyone who pays tax contributes to it, so it's free at the point of use rather than free altogether.
Do self-employed people not pay tax?
They do. They pay Income Tax at the same rates as employees, plus National Insurance. The difference is that nobody deducts it for them, so they work it out and report it themselves through Self Assessment.

Teacher Tips

Hook

  • Before revealing each answer, pick one learner from each side of the vote to explain their reasoning. The pattern of confident wrong answers is a quick read on the room, and shows which misconceptions to watch for once the ITZA pathways start.
  • The payslip card doesn't quite fit "when you buy these items", and that's useful. When you reach it, ask "You don't buy your own wages, so why does this one still count?" It's a neat way to introduce the idea that tax applies to earning as well as spending, before Pathway 1 makes it formal.
  • Once every item is revealed as taxed, the slide's exceptions (basic food, children's clothes, books) make a good follow-up rather than a footnote. Ask "Why do you think the government chose to leave these ones alone?" It's an early hint that tax involves deliberate choices, not blanket rules.

ITZA Pathways

  • The tax staircase in Pathway 1 is the concept worth protecting time for. The Personal Allowance (£12,570) is taxed at 0%, then 20% up to £50,270, 40% above that, and 45% at the top. Each rate only applies to the slice of income in that band, not the whole salary. If a learner says "So if I earn £51,000, I pay 40% on all of it", that's the one to correct before the class activity, as the budget calculation depends on it.
  • If your class is in Scotland, it's worth mentioning that the bands and rates in the ITZA content are the UK-wide ones, and Scotland's differ. There's an Expert Tap in Pathway 1 that covers this, so you can point learners to it if anyone asks "Wait, is that right though?"
  • As you circulate, ask "If tax were optional, which public services would disappear first?" For learners who are finding it hard to engage, make it personal: what would they lose, like the bus, their school or A&E? Early finishers can use the Pathway 1 AI Buddy to commit to numbers, such as "Where would you set the tax-free line, and the top rate?", and be ready to defend them. Others can move on to the Taxpayer Minigame once they've been through both pathways, as a bonus rather than a race to the end.

Classroom Activity

  • Work through the £60 billion calculation on the board before groups start, rather than just talking through it. Every ITZAland worker earns £42,570. The Personal Allowance takes the first £12,570 tax-free, which leaves £30,000 taxable. 20% of that is £6,000 tax per worker, and with 10,000,000 taxpayers that comes to £60 billion. It's the same staircase learners met in Pathway 1, now scaled up, so say that connection out loud.
  • Talk through all six spending areas before groups start, so nobody is guessing what ‘Infrastructure & Environment’ covers mid-task. Debt Interest is fixed at £6 billion and already spent, which leaves £54 billion to place across the other five.
  • The slide gives numbers for both rules: every area must get at least £2 billion, and no area can get more than £24 billion. Say them out loud once before groups begin, and ask groups to check their total comes to exactly £60 billion, including the £6 billion of debt interest, before they move on.
  • Give groups the full 5 minutes to build their first allocation before they see a scenario. That first table shows their own instincts. The 3-minute adjustment that follows is where the thinking happens, because learners have to justify what they moved and what they gave up, not just build from scratch.
  • If you have more than three groups, you could repeat the three scenarios. Two groups with the same scenario can then compare their adjusted budgets in the feedback, which tends to be a sharper discussion than groups presenting on their own.
  • For the class discussion, these questions bring out the trade-offs best: "What problem were you solving when you gave this area more money?" "What happens to the people who rely on the area you cut?" "Who benefits most from your budget, and who loses out?" "Is this budget a loss to the taxpayer, or an investment? What's your evidence?" The debrief slide adds "What are the biggest differences between the budgets, and which one works best?" and "What did governments want to fund but couldn't, and what follows from that?"

Plenary

  • Part 2 asks how learners' understanding of tax has changed, and which idea made them see it differently. If an answer just restates a fact, gently ask what they used to think. "I learnt tax pays for the NHS" is Part 1. "I used to think tax was money disappearing, and now I think of it as buying something together" is Part 2.
  • The lock-in line is from Franklin D. Roosevelt, who was US president in the 1930s and 40s, in a 1936 speech: "Taxes… are the dues that we pay for the privileges of membership in an organized society." It's worth mentioning if a learner asks where it's from, as it lands better as a considered idea than as an anonymous slogan.
  • If the plenary runs short, learners can finish Part 2 at home. It helps if they've each made their own copy of the journal and saved it somewhere they'll find it, like a folder on their laptop or school drive.

    The Tax That Broke An Empire

    The British put a tax on salt in India that reached every household. Gandhi's open defiance of it, the Salt March of 1930, became a turning point in India's struggle for independence. Why would a tax on something as ordinary as salt make so many people so angry?
