Understanding Tax Brackets and How They Work in 2023

Tax brackets are the foundation of how the U.S. federal income tax system operates. A tax bracket is a range of income amounts, each associated with a specific tax rate. Many people misunderstand tax brackets, thinking that earning more money automatically pushes all their income into a higher tax rate. This is incorrect. The U.S. uses a progressive tax system, which means different portions of your income are taxed at different rates.

Here's how it actually works: Imagine your income is divided into segments, and each segment is taxed according to its bracket. If you're single and earned $50,000 in 2023, not all of that income would be taxed at the same rate. Instead, the first portion (roughly $11,000) would be taxed at 10%, the next portion at 12%, and so on, depending on where it falls within the bracket structure. Only the income that falls into the highest bracket you reach gets taxed at that highest rate.

In 2023, there were seven federal income tax brackets for individuals: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. The specific income ranges for each bracket depended on your filing status. Filing status includes categories like single, married filing jointly, married filing separately, and head of household. Each status had different income ranges because the tax code recognizes that household structures vary.

The 10% bracket was the lowest rate and applied to the first portion of everyone's income. The 37% bracket was the highest and only applied to income above a certain threshold. For example, if you were single in 2023, the 37% bracket applied only to income above $578,100. This meant that very few people had their entire income taxed at 37%. Instead, most of their income fell into lower brackets.

Practical takeaway: When reviewing your income and taxes, remember that moving into a higher tax bracket doesn't mean your entire paycheck gets taxed at a higher rate—only the portion of income that falls into that bracket is taxed at that rate.

2023 Tax Brackets for Single Filers

Single filers made up a significant portion of tax returns filed in 2023. The tax brackets for single filers established specific income thresholds where tax rates increased. Understanding your bracket helps you predict how much federal income tax you might owe.

For 2023, single filers faced the following brackets:

• 10% on income up to $11,000
• 12% on income from $11,000 to $44,725
• 22% on income from $44,725 to $95,375
• 24% on income from $95,375 to $182,100
• 32% on income from $182,100 to $231,250
• 35% on income from $231,250 to $578,100
• 37% on income over $578,100

These brackets were adjusted from the previous year to account for inflation. The IRS adjusts tax brackets annually to prevent "bracket creep," which occurs when inflation pushes people into higher brackets without any real increase in purchasing power. In 2023, most brackets increased by roughly 7% compared to 2022, reflecting the year-over-year inflation.

Let's look at a practical example. Sarah is single and earned $60,000 in 2023 from her job. Her tax calculation would work like this: The first $11,000 is taxed at 10%, resulting in $1,100. The next $33,725 (from $11,000 to $44,725) is taxed at 12%, resulting in $4,047. The remaining $15,275 (from $44,725 to $60,000) is taxed at 22%, resulting in $3,360.50. Her total federal income tax would be approximately $8,507.50, giving her an effective tax rate of about 14.2%.

Many single filers found themselves in the 12% or 22% brackets, as these brackets covered middle-income ranges. The 24% bracket and above typically applied to higher earners, though some professionals and business owners reached these brackets.

Practical takeaway: Calculate which bracket your income falls into by adding up your income and matching it to the ranges above. Remember that you only pay the higher rate on the income within that bracket, not on your entire income.

2023 Tax Brackets for Married Couples Filing Jointly

Married couples filing jointly had different income thresholds than single filers, reflecting the recognition that married couples often have combined household income. The joint brackets were generally higher than single brackets, which can result in a tax benefit for married couples compared to two single filers.

The 2023 tax brackets for married couples filing jointly were:

• 10% on income up to $22,000
• 12% on income from $22,000 to $89,075
• 22% on income from $89,075 to $190,750
• 24% on income from $190,750 to $364,200
• 32% on income from $364,200 to $462,500
• 35% on income from $462,500 to $693,750
• 37% on income over $693,750

Notice that the income ranges for married couples filing jointly were roughly double those for single filers, but not exactly. This is by design. The difference creates what some refer to as the "marriage bonus" for some couples and a "marriage penalty" for others, depending on how their incomes compare.

Consider this example: Tom and Jessica are married and filed jointly in 2023. Their combined income was $120,000. Under the married filing jointly brackets, the first $22,000 is taxed at 10% ($2,200), the next $67,075 (from $22,000 to $89,075) is taxed at 12% ($8,049), and the remaining $30,925 (from $89,075 to $120,000) is taxed at 22% ($6,803.50). Their total federal income tax would be approximately $17,052.50, or an effective rate of about 14.2%.

Married couples who each earned different amounts sometimes found strategic value in reviewing their filing status. Some couples with very different income levels might explore whether filing separately made sense, though this was less common and required careful calculation. Most married couples benefited from filing jointly.

Practical takeaway: If you're married, confirm you're using the correct bracket table (married filing jointly or married filing separately). The difference in brackets can significantly affect your tax calculation.

Other Filing Statuses: Head of Household and Married Filing Separately

Beyond single and married filing jointly, the tax code provided other filing statuses for specific situations. Head of household was designed for unmarried individuals who paid more than half the household expenses and lived with a dependent. Married filing separately was available for couples who chose not to file jointly, though this was generally less favorable.

The 2023 head of household brackets were:

• 10% on income up to $15,700
• 12% on income from $15,700 to $59,850
• 22% on income from $59,850 to $95,350
• 24% on income from $95,350 to $182,100
• 32% on income from $182,100 to $231,250
• 35% on income from $231,250 to $578,100
• 37% on income over $578,100

Head of household status offered broader bracket ranges than single filers but narrower than married filing jointly. This status was common among single parents, guardians of dependents, and people providing financial support to relatives living in their home.

For married filing separately, the brackets were identical to single filers. This status was rarely beneficial because
