One of the most misunderstood income tax concepts is the difference between the marginal tax rate and the effective tax rate. Understanding the difference is crucial to making smart tax strategy decisions.
In the U.S. we have what’s called a progressive income tax, which simply means the more money you make, the more money you might have to pay in taxes. There is a bracket system in place to make our income tax progressive and is the reason why the concepts of effective tax rates and marginal tax rates are so often misunderstood. Below is listed the new tax brackets resulting from the Tax and Jobs Act signed into law in December 2017.
Rate Individuals Married Filing Jointly
10% Up to $9,525 Up to $19,050
12% $9,526 to $38,700 $19,051 to $77,400
22% 38,701 to $82,500 $77,401 to $165,000
24% $82,501 to $157,500 $165,001 to $315,000
32% $157,501 to $200,000 $315,001 to $400,000
35% $200,001 to $500,000 $400,001 to $600,000
37% over $500,000 over $600,000
As Example: A person filing taxes as an individual beginning in 2018 would have their first $9,525 of income taxed at 10%. Earnings over $9,525 up to $38,700 are taxed at 12%, and so on. The bracket system often leads to people believing that all of their income is taxed based on rate taken from the bracket where their income matches. But this does not mean that all of this individual’s income is going to be taxed at 22%. It just means that their marginal tax rate is 22%.
So, if the individual in our example earns $60,000 in salary, they may believe that they are in the 22% tax bracket. In reality, the first $9,525 is taxed at 10% ($952.50), the next $29,175 is taxed at 12% ($3,501.00), and the remaining $21,300 is taxed at 22% ($4,686.00)
Salary (Income) Tax Rate Tax Liability
$ 9,525 10% $ 925.50
$29,175 12% $3,501.00
$21,300 22% $4,686.00
What is a Marginal Tax Rate?
- The marginal tax rate is the amount of tax paid on each additional dollar of income.
What is an Effective Tax Rate?
- The effective tax rate is the percentage of your taxable income that you effectively pay in taxes.
In our example above, taxes owed ($9,112.50) divided by taxable income ($60,000) is equal to 15.1%, making effective tax rate is 15.1%.
Knowing the difference between these two concepts is crucial for making good tax strategy decisions. Many people believe their effective tax rate is much higher than it actually is because they focus on their marginal tax rate.
