In this article, I will explain a few basic tax concepts related to our Federal income tax system that includes Tax Brackets, Marginal Tax Rate, and Effective Tax Rate. In the United States, we have a progressive tax system where people who earn more money generally pay more.
Tax Brackets
There are seven Federal tax brackets, and you can see the most up-to-date tax brackets here. The table below gives you the 2019 marginal tax brackets for single, married couples filing jointly, and head of household.
Marginal Tax Rate | Single | Married, filing jointly | Head of Household |
---|---|---|---|
10% | $0 to $9,700 | $0 to $19,400 | $0 to $13,850 |
12% | $9,701 to $39,475 | $19,401 to $78,950 | $13,851 to $52,850 |
22% | $39,476 to $84,200 | $78,951 to $168,400 | $52,851 to $84,200 |
24% | $84,201 to $160,725 | $168,401 to $321,450 | $84,201 to $160,700 |
32% | $160,726 to $204,100 | $321,451 to $408,200 | $160,701 to $204,100 |
35% | $204,101 to $510,300 | $408,201 to $612,350 | $204,101 to $510,300 |
37% | $510,301 or more | $612,351 or more | $510,301 or more |

Marginal Tax Rate
One of the biggest misconceptions is that your entire income is taxed at your tax bracket. For example, if you make $100,000, you have to pay 24% or $24,000. In fact, that’s not the case at all.
Let’s look at the following example using 2019 rates, suppose your taxable income (after deductions and exemptions) is exactly $100,000 and your status is Single; then your tax would be calculated like this:
$9,700 – $0 | = | $9,700 x 10% | = | $970.00 |
$39,475 – $9,700 | = | $29,775 x 12% | = | $3,573.00 |
$84,200 – $39,475 | = | $44,525 x 22% | = | $9.839.50 |
$100,000 – $84,200 | = | $15,800 x 24% | = | $3,792.00 |
Total | = | $18,174.50 |
The $100,000 taxable income puts you in the 24% marginal tax rate bracket, but this only applies to income above $84,200. Income below that amount is taxed at the appropriate tax rate as per the above chart.
When we are talking about tax deductions, e.g., your IRA contribution or charitable donations, we often talk about reducing our tax burden at the highest tax bracket. For example, “My $6,000 IRA contribution would cut my taxable income by $1,440 at my 24% marginal tax rate.” This is accurate because your tax deductions are applied against your highest tax bracket income first.
Effective Tax Rate
Effective tax rate, or your actual tax rate, is simply the amount you are paying to the government as a percentage of your taxable income. In the example above, your effective tax rate is 18.17% ($18,175 divided by $100,000).
This means that your effective tax rate will always be less than your marginal tax rate.
I hope this article helps you better understand our tax system, specifically, tax brackets, marginal tax rate, and effective tax rate.
