Taxes on Wages

Key terms

A wage tax looks as if it falls on labourers. Ricardo argues that, when wages are near the cost of maintaining workers and their families, the long-run burden moves to profits.

TermMeaning
Gross wageThe money wage before tax
Net wageWhat the worker keeps after tax
Natural wageThe wage compatible with maintaining the labouring population
Market wageThe wage currently paid
Wage advanceThe capitalist's wage payment before output is sold
Incidence shiftMovement of the burden from legal payer to another income share

Ricardo's incidence chain

At first, the worker remits the tax and net wages fall. If the old wage was only enough to buy necessaries, that lower net wage cannot persist without affecting labour supply.

The tax is called a wage tax, but Ricardo treats its ultimate effect as closely resembling a direct tax on profits.

Worked miniature: restoring the net wage

Suppose the weekly natural wage is £10 and the state taxes gross wages at 20 percent.

If gross pay stayed £10, the worker would keep only £8. To restore a £10 net wage:

required gross wage x (1 - tax rate) = required net wage

gross wage x 0.80 = £10
gross wage = £12.50
ItemBeforeAfter adjustment
Gross wage£10.00£12.50
Wage tax£0.00£2.50
Net wage£10.00£10.00
Employer's weekly wage cost£10.00£12.50

The worker sends £2.50 through payroll, but the employer advances £2.50 more. In Ricardo's model, profits absorb the difference.

Use the Lab to move the market wage away from the natural wage. The adjustment back toward subsistence is the mechanism Ricardo relies on when he says the wage tax cannot remain on workers indefinitely.

Why commodity prices do not generally rise

An individual manufacturer might try to add the higher wage bill to price. But the wage tax affects labour used in every trade.

Because the pressure is general, capital cannot escape it merely by moving from cloth to farming. Ricardo therefore resists the claim that a wage tax simply raises all commodity prices.

Wage tax versus raw-produce tax

The two taxes can both lower profits, but their first steps differ.

TaxFirst price effectRoute to profits
Tax on cornCorn price risesDearer subsistence raises money wages
Tax on wagesNet pay falls firstGross wages rise to restore subsistence

The farmer can pass a corn-specific production tax into corn's price after marginal supply contracts. A general wage tax does not single farming out relative to manufacturing.

Assumptions and limits

Ricardo's conclusion is strongest under demanding assumptions:

  • wages begin near subsistence;
  • workers cannot permanently accept lower consumption;
  • labour supply responds over time;
  • the tax is general rather than confined to one occupation;
  • employers cannot indefinitely earn less than the ordinary rate in one sector only.

If wages contain a large surplus above subsistence, workers may bear more of the tax for longer. The model is a long-run distribution theory, not a claim that every payslip tax is instantly reimbursed.

Key takeaways

  • The legal wage-tax payer can differ from the ultimate bearer.
  • Restoring a £10 net wage under a 20 percent tax requires £12.50 gross pay.
  • A general rise in wage costs lowers the residual profit share in Ricardo's model.
  • A wage tax and a corn tax can converge on lower profits through different paths.
  • The conclusion depends on subsistence wages and long-run labour-supply adjustment.
