I. Classification Based on Fairness
This classification examines how the tax burden is distributed across different income levels to determine the “equity” of the system.
1. Progressive Taxation
- Definition: A system where the tax rate increases as the taxable income or amount rises It is based on the “ability to pay” principle.
- Impact: Individuals with higher incomes are required to pay a greater proportion of their income in taxes compared to those with lower incomes. It is considered fair because it places a heavier financial burden on those most able to bear it.
- Mathematical Example: Assume an income tax system with the following slabs:
- Individual A (Low Income): Earns ₹2,50,000 per year. Tax Rate = 0%. Total Tax = ₹0.
- Individual B (High Income): Earns ₹12,00,000 per year. Tax Rate = 30% on the top bracket.
- Fairness Logic: Individual B contributes a significantly larger percentage of their total earnings than Individual A.
2. Regressive Taxation
- Definition: A system where the tax rate effectively decreases as the taxable amount or income level increases.
- Impact: Lower-income individuals pay a higher proportion of their total income in taxes than higher-income individuals. This leaves the poor with less disposable income and is often criticized for its heavy burden on the vulnerable.
- Mathematical Example: Assume a flat property purchase tax of ₹10,000 regardless of the property’s area or the buyer’s income:
- Buyer A (Income ₹1,00,000): The tax paid is (10,000 / 1,00,000) * 100 = *10% of their annual income.
- Buyer B (Income ₹10,00,000): The tax paid is (10,000 / 10,00,000) * 100 = 1% of their annual income.
- Fairness Logic: The person with the lesser income pays a much higher proportion of their wealth, making the tax regressive.
3. Proportional Taxation (Flat Tax)
- Definition: A system where individuals pay the same proportion or percentage of their income in taxes, regardless of whether their income is low, moderate, or high.
- Impact: The tax burden is distributed equally in terms of the rate applied.
- Mathematical Example: Assume a 10% tax on a product like sugar:
- Poor Person: Buys 1 kg of sugar (₹100). Tax = ₹10.
- Rich Person: Buys 1 kg of sugar (₹100). Tax = ₹10.
- Fairness Logic: Irrespective of the individual’s annual income, the tax rate remains the same for the same quantity of goods.
II. Classification Based on Who Pays (Direct vs. Indirect)
This classification distinguishes between the person on whom the tax is legally levied and the person who bears the final financial burden.
| Parameter | Direct Tax | Indirect Tax |
|---|---|---|
| Meaning | Levied on a person’s income or wealth and paid directly to the government. | Charged on a person who purchases goods or services; paid indirectly through an intermediary. |
| Incidence and Impact | The Impact (legal liability) and Incidence (money burden) fall on the same person. | The Impact is on the business/seller, but the Incidence falls on the final consumer (different persons). |
| Evasion | Tax evasion is possible (e.g., through underreporting). | Evasion is hardly possible as the tax is included in the price of the goods. |
| Shift of Burden | Cannot be shifted to another person. | Can be shifted from the seller to the buyer. |
Concept: Shifting the Tax Burden
Shifting occurs when the person or entity legally responsible for paying the tax (the Impact) transfers that cost to another party (the Incidence). In indirect taxation, these taxes are transferable in nature. For example, a manufacturer pays excise duty or GST to the government but “shifts” this burden to the end consumer by adding the tax amount to the retail price of the product.
III. Conceptual Check: Indirect and Regressive Simultaneously
A common tax like GST (Goods and Services Tax) or VAT (Value Added Tax) can be classified as both indirect and regressive at the same time:
- Why it is Indirect: It is not levied directly on an individual’s income. Instead, it is charged on the supply/consumption of goods and services and collected by the seller to be deposited with the government.
- Why it is Regressive: Although the GST rate on an item (like sugar) is proportional (everyone pays 10%), the burden is unequal. A poor person spends a much larger share of their total income on daily necessities than a rich person does. Therefore, even if they pay the same ₹10 tax on a good, that ₹10 represents a higher percentage of the poor person’s total earnings, fitting the definition of regressive taxation.
