Financing of Government Expenditure : Taxation

Government Budget Constraint

• Government expenditure, including interest payments on public debt, is financed through taxation, market borrowing and creation of new money.

• The Government budget constraint states that government spending is limited by the resources it can raise from taxes, borrowing and money creation.

• Government budget identity: G = T + ΔB + ΔM, where G = Government expenditure, T = tax revenue, ΔB = new borrowing through bond issuance, and ΔM = newly created money.

• Rearranging the equation gives (G − T) = ΔB + ΔM, showing that any budget deficit must be financed either through borrowing or money creation.

• When government expenditure exceeds tax revenue, a budget deficit arises.

• Therefore, deficit financing can be carried out through public borrowing, printing new money, or a combination of both.

• Taxation remains the primary source of financing government expenditure, while borrowing and money financing are mainly used when tax revenues are insufficient.

What is Tax?

• A tax is a compulsory payment imposed on individuals and companies to finance government expenditure incurred for the common welfare of society.

• Two essential features of a tax are that it is mandatory and that its proceeds are used for general public purposes rather than for providing a specific benefit to the taxpayer.

• Taxpayers cannot refuse to pay taxes, as payment is enforced by law.

• Taxes involve no direct quid pro quo, meaning there is no direct or immediate exchange of a particular service for the tax paid.

• Although no specific benefit is guaranteed to an individual taxpayer, the Government uses tax revenue to provide public goods and services that benefit society as a whole.

• Taxes are different from fees, which are compulsory payments made in return for a specific service or benefit provided by the Government.

• Examples of fees include television or radio licence fees and educational fees paid by students for receiving particular services.

• In the case of fees, there is a direct relationship between payment and the service received, unlike taxes.

• The amount of a fee generally covers only a part of the cost of the service provided, with the remaining cost borne by the Government for public welfare.

• Thus, while taxes finance general public benefits without direct return, fees are linked to specific services enjoyed by those who pay them.

Classification of Taxes

• Taxes can be classified as direct and indirect taxes, specific and ad valorem taxes, and progressive, proportional and regressive taxes.

• Direct taxes are those whose burden cannot be shifted to another person; the person who pays the tax also bears its burden. Examples include income tax, wealth tax and capital gains tax.

• In direct taxes, there is a direct relationship between the taxpayer and the tax-collecting authority.

• Indirect taxes are those whose burden can be shifted wholly or partly to others. The person paying the tax to the Government may pass it on to consumers through higher prices.

• Examples of indirect taxes include excise duty and sales tax. Though imposed on producers or sellers, the final burden is usually borne by consumers.

• In indirect taxes, the ultimate taxpayer and the Government are connected only indirectly through producers or sellers.

• Specific taxes are indirect taxes charged per unit of a commodity, irrespective of its value or price. Total tax revenue depends on the quantity sold or produced.

• Ad valorem taxes are levied as a percentage of the value of a commodity. Their amount rises automatically when the value of the commodity increases. Sales tax is a common example.

• Proportional taxes impose the same tax rate on all taxpayers regardless of the size of the tax base. Tax payment rises with income or wealth, but the rate remains unchanged.

• Progressive taxes impose higher tax rates as income, wealth or the tax base increases. Thus, richer individuals pay both a larger amount and a higher rate of tax. Income tax is a major example.

• Progressive taxation is based on the principle that those with greater ability to pay should contribute a larger share of their income.

• Regressive taxes impose lower tax rates as income increases, causing the tax burden to fall relatively more on poorer people than on richer people.

• Because regressive taxes are considered inequitable, modern governments generally avoid imposing them directly.

Principles or Canons of Good Tax System

• A good tax system should raise adequate revenue for the Government while also helping achieve important social and economic objectives.

• Adam Smith proposed four famous canons of taxation: Equality, Certainty, Convenience, and Economy, which remain fundamental principles of a sound tax system.

• These principles were formulated when the role of Government was limited mainly to defence, maintenance of law and order, and provision of basic public services.

• Since Adam Smith’s time, government functions and responsibilities have expanded significantly, requiring much larger public revenues.

• Modern governments are expected to maintain economic stability, achieve full employment, reduce income inequalities, operate as welfare states and promote economic growth and development.

• Therefore, while designing a tax system, modern economic objectives and government responsibilities must also be taken into account.

• Adam Smith believed that free private enterprise and market forces would ensure efficient use of resources and rapid economic growth if left largely unrestricted.

• His taxation principles were primarily aimed at enabling the Government to collect sufficient revenue without hampering economic activity.

• Modern economists have supplemented Smith’s canons with additional principles to ensure that taxation supports welfare, equity, stability and development.

• Thus, a modern tax system should not only generate revenue efficiently but also contribute to economic growth, social justice and overall public welfare.

Principle or Canon of Equality

• The first canon of a good tax system proposed by Adam Smith is the principle of equality or ability to pay.

• According to this principle, every individual should contribute to the Government according to his ability, which generally depends on the income earned under the protection of the State.

• Therefore, richer individuals should bear a larger tax burden than poorer individuals.

• Adam Smith supported a proportional tax system in which everyone pays the same percentage of income as tax.

• Modern economists, however, argue that because of the diminishing marginal utility of income, equality is better achieved through progressive taxation.

• Under a progressive tax, tax rates increase as income rises, causing higher-income groups to contribute a larger proportion of their income.

• Most countries today use progressive income taxes and other direct taxes to promote equity in taxation.

• The ability-to-pay principle includes horizontal equity, which requires that people in similar economic situations and with the same income should pay the same amount of tax.

• It also includes vertical equity, which requires that people with different income levels should bear different tax burdens according to their ability to pay.

• A good tax system should ensure both horizontal and vertical equity so that taxation is fair and just for all sections of society.

Canon of Certainty

• The canon of certainty is an important principle of a good tax system proposed by Adam Smith.

• According to this principle, the amount of tax, time of payment, method of payment and procedure of assessment should be clear, definite and known in advance to taxpayers.

• Taxes should not be arbitrary or subject to excessive discretion of tax authorities.

• Certainty in taxation helps individuals and businesses make informed decisions regarding work, saving and investment.

• When taxpayers know the exact tax liability, economic activities can be planned more efficiently and confidently.

• Lack of certainty weakens incentives to work, save and invest because future tax obligations become unpredictable.

• A tax system with excessive discretionary powers may encourage corruption, harassment of taxpayers and misuse of authority.

• Therefore, tax laws should be simple, transparent and specific so that tax officials have minimal scope for arbitrary assessments.

• A good tax system ensures security and predictability for taxpayers, thereby promoting economic efficiency and public confidence in taxation.
