Pearson Edexcel International GCSE Economics: Fiscal policy, taxes and deficits (4EC1) – Revision Notes

These notes condense specification point 2.1.2 a), fiscal policy, from the Pearson Edexcel International GCSE Economics (4EC1) specification, Issue 3, February 2026 (Paper 2: Macroeconomics and the Global Economy). For the full explanations and longer worked examples, read the study guide. Then test yourself with the practice questions.

Revenue and spending at a glance

Revenue	Examples
Direct taxes	Income tax, corporation tax
Indirect taxes	Sales tax or VAT, excise duties
Main spending areas	Healthcare, education, social protection (benefit payments), defence and public order, infrastructure, debt interest

Formulas

Measure	Formula
Net pay	Gross pay − income tax
Average tax rate	Tax paid ÷ gross pay × 100
Tax in a price	Pre-tax price × tax rate
Pre-tax price from a tax-inclusive price	Tax-inclusive price ÷ (1 + rate)
Fiscal deficit	Spending − revenue (spending larger)
Fiscal surplus	Revenue − spending (revenue larger)
Deficit as a share of GDP	Deficit ÷ GDP × 100
Share of spending	Item ÷ total spending × 100
Percentage change	(New − old) ÷ old × 100

Method boxes

Banded income tax (steps)

1. Split gross pay into the bands.
2. Multiply the income in each band by its rate.
3. Add the amounts to get total tax.
4. Subtract from gross pay for net pay.
5. Divide tax by gross pay for the average rate.

Worked reminder. Gross pay 36,000. Bands: 0% to 8,000; 15% from 8,001 to 24,000; 35% above 24,000.

• 16,000 × 0.15 = 2,400
• 12,000 × 0.35 = 4,200
• Tax = 6,600; net pay = 29,400; average rate = 6,600 ÷ 36,000 × 100 = 18.3%

Finding the tax inside a price. A tax-inclusive price of 138 with a 15% tax: pre-tax price = 138 ÷ 1.15 = 120. Tax = 138 − 120 = 18.

Deficit questions (steps)

1. Total revenue and total spending.
2. Subtract the smaller from the larger.
3. Label it deficit or surplus.
4. If asked, divide by GDP and multiply by 100.

Worked reminder. Revenue 640, spending 700, GDP 3,000. Deficit = 60; as a share of GDP = 60 ÷ 3,000 × 100 = 2.0%. If revenue were 910 and spending 880, there would be a surplus of 30.

Effect chains on the macroeconomic objectives

Objective	Expansionary policy	Contractionary policy
Economic growth	Demand rises, so output and GDP rise	Demand falls, so growth slows
Unemployment	More output needs more workers, so it falls	Firms cut output and jobs, so it may rise
Inflation	Demand outruns capacity, so prices may rise	Demand eases, so price rises slow
Current account	Higher incomes pull in imports, so it may worsen	Lower import spending, so it may improve
Redistribution	Higher benefits and progressive taxes shift income to the poor	Cuts in benefits or higher indirect taxes can hit low incomes
Environment	Spending on clean energy and transport; taxes on pollution	Cuts to green spending may reduce protection

Tax cuts: a cut in income tax raises net pay. A tax cut of 2% on gross pay of 30,000 adds 600 to net pay. Part is saved and part goes on imports, so the boost to domestic demand is smaller than the cut.

Deficit and surplus: impacts

	Positive	Negative
Deficit	Pays for infrastructure and services; supports demand in a downturn	Debt interest rises; possible crowding out of private investment; higher future taxes
Surplus	Pays off debt; builds a reserve	Takes demand out of the economy; may mean cuts to services

Deficit is a yearly flow. National debt is the total stock of past borrowing.

Must-know distinctions

Pair	The difference
Direct and indirect tax	Direct: on income or profit, paid by the taxpayer. Indirect: on spending, built into the price
Deficit and national debt	Deficit: one year’s gap. Debt: the total stock of borrowing
Expansionary and contractionary	Expansionary raises demand. Contractionary reduces it
Gross and net pay	Net pay is what remains after income tax
Revenue and borrowing	Borrowing is how a deficit is financed. It is not revenue

Worked reminder: a tax cut with leakages

Country E (illustrative) has GDP of 40,000 (millions). A tax cut gives 500,000 workers 1,200 each, which is 600 million.

• Households spend 70%: 600 × 0.7 = 420 million; they save 180 million.
• Imports take 25% of the new spending: 420 × 0.25 = 105 million.
• Domestic demand rises by 420 − 105 = 315 million.
• As a share of GDP: 315 ÷ 40,000 × 100 = 0.79%.

The lesson for evaluation: the bigger the share saved or spent on imports, the weaker the boost to growth, jobs and prices at home.

Which policy for which problem?

Problem	Fiscal response	Typical risk
Slow growth or high unemployment	Expansionary: more spending or lower taxes	Bigger deficit; higher inflation if capacity is short
Rising prices from strong demand	Contractionary: less spending or higher taxes	Slower growth and higher unemployment
Large gap between rich and poor	Progressive income tax and benefits	Taxpayers may have less reason to work or invest
Pollution	Tax on polluting goods; spending on clean alternatives	Higher prices for consumers
Weak transport and power networks	Spending on infrastructure	Costly to fund; slow to deliver

Evaluation toolkit

• Size of the effect: savings and imports leak out.
• Time lags: projects take time to start and finish.
• Spare capacity: expansion works best when there are idle resources.
• Cost: borrowing now means debt interest later.
• Winners and losers: who pays and who gains?

A short evaluation structure: make a point, add its limit, then give a judgement that says which factor matters most in the case described.

Quick self-test

1. State two direct taxes.
2. State two indirect taxes.
3. A government spends 700 and collects 640. State the size and type of the budget balance.
4. A sales tax of 20% is added to a pre-tax price of 80. Find the shelf price.
5. Gross pay is 36,000 and total income tax is 6,600. Find the average tax rate to one decimal place.
6. A government spends 900 in total, 180 of it on healthcare. What percentage is that?
7. Debt interest rises from 40 to 55. Find the percentage increase.
8. Name two main areas of government expenditure.
9. A government raises spending by 30 in an economy with GDP of 1,500. Find the direct effect as a percentage of GDP.
10. Explain one way a fiscal surplus could harm growth.

Answers

1. Income tax and corporation tax.
2. Sales tax (or VAT) and excise duty.
3. Spending exceeds revenue, so a deficit of 60.
4. 80 × 1.2 = 96.
5. 6,600 ÷ 36,000 × 100 = 18.3%.
6. 180 ÷ 900 × 100 = 20%.
7. (55 − 40) ÷ 40 × 100 = 37.5%.
8. Any two of healthcare, education, social protection, defence, infrastructure, debt interest.
9. 30 ÷ 1,500 × 100 = 2.0% of GDP.
10. A surplus is reached by higher taxes or lower spending. This reduces total demand, so firms may cut output and growth may slow.

Where marks are usually lost

• Giving a definition with only one part, such as “taxes” with no mention of spending or the purpose.
• Mixing up direct and indirect taxes, especially calling a sales tax direct.
• Mixing up a deficit (one year, a flow) with the national debt (the total owed).
• Calling every deficit bad and every surplus good, with no consequences stated.
• Stopping a chain after one step, for example “spending rises so growth rises”.
• Leaving out units or workings on a calculation, or rounding too early.
• Using a general point that is not set in the context of the question.
• Giving a conclusion in an evaluation answer that does not follow from the points made.
• Ignoring the objective named in the question, such as the current account.
