Explain how tax and government spending affect business
Distinguish effects of taxes on business profit from effects on household income, and connect government spending to demand.
Section 6 · External influences on business activity
Cambridge IGCSE Business 0264, 2027–2029 syllabus, Topic 6. Trace each external change through the business and state which effects depend on its market, costs or response. Candidates are not assessed on exchange-rate calculations. Written practice is self-checked and does not certify exam readiness
Before you begin
- No previous study of external influences is assumed. Identify who is affected, which business decision changes and what evidence or condition would affect the outcome.
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
How may a higher household income tax affect a retailer?
What you will learn
- Explain tax effects on profit
- Trace income tax through household spending
- Explain government-spending effects conditionally
Identify who pays and through which channel
A change in a tax on business profits can directly alter the amount of profit retained after tax, other things equal. A tax on people's income can change disposable income and therefore some customers' spending; that can affect business sales and profit indirectly.
The effect depends on the tax, the people affected, the business's customer group and how it responds. Do not treat all taxes as if they apply to the same party or operate through the same mechanism.
Government spending can change business demand
Higher government spending may create contracts for suppliers, fund services or support incomes and demand. A cut may reduce orders or public services relevant to some businesses.
Not every firm benefits equally, and the outcome depends on what the spending funds, who receives income and how the government finances it. Use case facts and distinguish a direct contract from an indirect demand effect.
Pause and explain
Why may a government-spending increase affect firms differently?
Worked example
A government increases income tax on households and also awards a road-maintenance contract. Explain one possible effect on a local café and one on a construction supplier.
Show the worked solution
- Some café customers may have less disposable income and reduce optional spending.
- The road contract may directly increase orders for the construction supplier.
- Each effect depends on the business's customers and contract conditions.
Answer The café could face weaker discretionary spending if affected households have less disposable income. The construction supplier could gain direct orders under the contract, provided it meets the terms and the contract covers its products; neither effect is automatic for every firm.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
A tax on company profits rises. Explain the direct effect on a profitable firm and one factor that may change its response.
Give me a hint
Hold revenue and other costs constant first, then consider behaviour.
Compare my reasoning
- More tax can reduce after-tax profit, other things equal.
- The firm may review investment, costs, prices or legal business plans.
- Its response depends on alternatives, demand and cash needs.
A higher tax on profits can reduce the amount retained after tax if other figures stay constant. The firm might review investment or costs, but its response depends on demand, cash needs, legal rules and the options available; it cannot assume a price increase will succeed.
Look for these in your work
- Direct profit channel
- Response described
- Conditions considered
A rise in household income tax affects a firm's customers, while its own tax rate is unchanged. Explain why sales could change without a direct change in its tax bill.
Give me a hint
Trace disposable income to customer spending.
Compare my reasoning
- Some affected households may have less disposable income.
- They may change spending on the firm's products.
- The effect varies with customer income, product necessity and alternatives.
The firm's tax rate is unchanged, but customers' disposable incomes may fall. If customers reduce purchases, sales and profit could be affected indirectly; the result depends on customer groups and how essential or substitutable the product is.
Look for these in your work
- Direct and indirect tax effects separated
- Spending channel traced
- Market conditions qualified
A public hospital increases spending on locally sourced supplies. Explain one direct opportunity for a supplier and one limitation for other local firms.
Give me a hint
A contract helps firms that meet the purchasing requirement; indirect effects differ.
Compare my reasoning
- An eligible supplier may receive direct orders.
- Other firms may not sell the required supplies or win a contract.
- Check tender conditions, capacity and payment timing.
A local supplier that meets the specification could gain orders directly. Other firms may not be eligible or may not benefit from this contract; even the selected supplier should check capacity, costs and payment timing before accepting it.
Look for these in your work
- Direct benefit identified
- Not generalized to all firms
- Contract viability checked
Common mistakes
- Confusing income taxes on households with taxes on business profits
- Assuming all government spending benefits every firm
- Ignoring tax or contract details
What can you explain now?
How may a higher household income tax affect a retailer?
Compare with the explanation
It may reduce some customers' disposable income
This can affect spending and demand.
