Taxation Systems in Public Finance
(Important for JKSSB, SSC, UPSC, UGC NET Competitive Exams)
By Home Academy Concept Notes with Examples
Tax systems are classified according to how the tax rate changes with the income of taxpayers. These concepts are important in public finance and frequently asked in accounting, economics, and taxation exams.
1. Progressive Tax System
A progressive tax system is a taxation system in which the tax rate increases as the income of the taxpayer increases. In this system, individuals with higher income pay a higher percentage of their income as tax compared to individuals with lower income.
This system is widely used in modern economies because it promotes income equality and social justice.
India follows a progressive taxation structure under the **Income Tax Act 1961 and guided by principles of the **Constitution of India.
Example
Suppose the tax structure is as follows:
Income up to ₹3,00,000 → 0% tax
Income ₹3,00,000 – ₹6,00,000 → 10% tax
Income ₹6,00,000 – ₹10,00,000 → 20% tax
Income above ₹10,00,000 → 30% tax
Person A earns ₹4,00,000 and pays tax at a lower rate.
Person B earns ₹15,00,000 and pays tax at a higher rate.
Thus the tax rate increases with income.
Important Exam Point
India’s personal income tax structure is a progressive tax system.
2. Proportional Tax System
A proportional tax system (also called flat tax system) is a taxation system in which all taxpayers pay the same percentage of tax regardless of income level.
The tax rate remains constant even if income increases.
Example
Suppose the tax rate is 10% for everyone.
Person A earns ₹2,00,000 → tax = ₹20,000
Person B earns ₹10,00,000 → tax = ₹1,00,000
Both pay 10% of their income, so the tax rate is constant.
Important Exam Point
The proportional tax system is simple and easy to administer but it does not reduce income inequality.
3. Regressive Tax System
A regressive tax system is a system in which the tax rate decreases as income increases. This means lower-income individuals pay a higher proportion of their income in taxes compared to richer individuals.
This system is generally considered unfair because it puts more burden on poor people.
Example
Suppose the tax structure is:
Income up to ₹3,00,000 → 20% tax
Income ₹3,00,000 – ₹10,00,000 → 10% tax
Income above ₹10,00,000 → 5% tax
Person A earns ₹2,00,000 and pays 20% tax.
Person B earns ₹15,00,000 and pays only 5% tax.
Here the tax rate decreases as income increases, making it regressive.
Important Exam Point
Some indirect taxes like GST on essential goods can have a regressive effect because poor people spend a larger share of their income on consumption.
4. Degressive Tax System
A degressive tax system is a mixed system where the tax rate increases with income up to a certain limit and then remains constant after that.
This system combines features of both progressive and proportional taxation.
Example
Income up to ₹5,00,000 → 10% tax
Income ₹5,00,000 – ₹10,00,000 → 20% tax
Income above ₹10,00,000 → 20% tax
Here the tax rate increases initially but then becomes constant.
Comparison Table (Important for Exams)
| Tax System | Tax Rate Behaviour | Burden on Rich | Burden on Poor | Example |
|---|---|---|---|---|
| Progressive | Rate increases with income | Higher | Lower | Income tax in India |
| Proportional | Same rate for all | Equal percentage | Equal percentage | Flat tax system |
| Regressive | Rate decreases with income | Lower | Higher | Some indirect taxes |
| Degressive | Rate increases then constant | Moderate | Moderate | Mixed systems |
Important Points for Competitive Exams
Progressive taxation aims to reduce income inequality.
Proportional taxation applies a constant tax rate regardless of income level.
Regressive taxation places greater burden on low-income groups.
Most modern economies use progressive income taxation.
Indirect taxes may have regressive effects because everyone pays the same price regardless of income.
