Learn what a tax rate is, how marginal and effective tax rates differ, and why the quoted rate does not always equal the true tax burden.
A tax rate is the percentage applied to a tax base, such as income, property value, sales, or gains, to determine how much tax is owed.
The phrase sounds simple, but the actual tax burden depends on what is being taxed, what deductions or credits apply, and whether the system uses flat or progressive brackets.
Common examples include:
A tax system can also have both a marginal rate and an effective rate, which are not the same thing.
Suppose a person has taxable income of $80,000 and the top bracket that applies to the last dollars earned is 24%.
That does not mean the entire $80,000 is taxed at 24%. Instead, earlier brackets may be taxed at lower rates, producing an average tax burden below the marginal rate.
A taxpayer says, “I moved into a higher bracket, so every dollar I earn is now taxed at the higher rate.”
Answer: No. In a progressive system, only the income inside the higher bracket is taxed at that higher marginal rate.
