Legal Definitions - proportional tax

A proportional tax is a tax system where the tax rate remains constant for all individuals or entities, regardless of their income, wealth, or the value of the item being taxed. This means that everyone pays the same percentage of their taxable base, even though the actual dollar amount paid will increase as the base (e.g., income or property value) increases. It is also commonly referred to as a flat tax.

• Example 1: Flat Income Tax

  Imagine a country decides to implement a national income tax where every citizen pays exactly 10% of their taxable income, no matter how much they earn. If an individual earns $40,000 per year, they would pay $4,000 in taxes. If another individual earns $200,000 per year, they would pay $20,000 in taxes. In both cases, the tax rate applied is a consistent 10%, making it a proportional tax system for income.

• Example 2: State Sales Tax

  Consider a state that imposes a 5% sales tax on most retail goods. When a consumer purchases a new book for $20, they pay $1 in sales tax (5% of $20). If another consumer buys a new refrigerator for $1,000, they pay $50 in sales tax (5% of $1,000). The sales tax is proportional because the 5% rate is applied uniformly to the purchase price, regardless of the item's cost or the buyer's income level.

• Example 3: Property Tax on Assessed Value

  A local municipality levies a property tax of 0.8% on the assessed value of all residential properties. A homeowner whose property is assessed at $300,000 would pay $2,400 in property taxes (0.8% of $300,000). A homeowner with a property assessed at $800,000 would pay $6,400 in property taxes (0.8% of $800,000). This is a proportional tax because the 0.8% tax rate is applied equally to the assessed value of every property, ensuring the percentage taken remains constant across different property values.
