Inflation, impôts sur le revenu et revenu réel disponible

  • Economics


The purpose of this text is to examine how federal and Quebec provincial income tax policies have affected real disposable income of taxpayers in the context of the rapid inflation of the last five years. It finds that the net effect of federal fiscal reform since 1970 has been to make the tax structure more progressive. Low-income taxpayers have benefitted from lower tax rates in real terms but real tax rates have risen for those with incomes above approximately $14,000. On the provincial level, on the other hand, there has been virtually no change in the tax structure except for an increase in the threshold level below which no tax is paid. All, except the very poorest taxpayers (single persons earning less than $2,578 in 1970 or $3,200 in 1974 and married couples with two children earning less than $5,200 in 1970 or $6,300 in 1974), have paid higher taxes in real terms every year from 1970 to 1974. This is true even when provincial family allowances (which the province considers as a tax credit and as a substitute for personal exemptions for children under 16) are deducted from provincial income tax.
