Tax bracket for investors

A tax bracket is a range of taxable income taxed at a single federal rate. The US has seven brackets ranging from 10% to 37%. Your bracket determines your marginal tax rate—the rate applied to short-term capital gains and ordinary dividends. Brackets are adjusted annually for inflation. Investors often overestimate their bracket; understand yours to make tax-efficient investing decisions.

2024 federal brackets (single filer)

• 10%: $0–$11,600
• 12%: $11,600–$47,150
• 22%: $47,150–$100,525
• 24%: $100,525–$191,950
• 32%: $191,950–$243,725
• 35%: $243,725–$609,350
• 37%: $609,350+

Example: Single filer with $150,000 taxable income. The income is taxed as:

• First $11,600 at 10%
• Next $35,550 at 12%
• Next $53,375 at 22%
• Remaining $49,475 at 24%

Total brackets climbed = your marginal rate is 24%.

Married filing jointly (2024)

• 10%: $0–$23,200
• 12%: $23,200–$94,300
• 22%: $94,300–$201,050
• 24%: $201,050–$383,900
• 32%: $383,900–$487,450
• 35%: $487,450–$731,200
• 37%: $731,200+

Married brackets are roughly double single brackets (they used to be exactly double, but are now slightly higher).

Head of household (2024)

Head of household brackets fall between single and married (for taxpayers with dependents):

• 10%: $0–$17,400
• 12%: $17,400–$66,550
• And so on…

How your bracket affects investment decisions

Knowing your bracket is critical for investment decisions. A short-term capital gain is taxed at your bracket rate. If you are in the 24% bracket, realizing a $50,000 short-term gain costs $12,000 in tax.

A long-term capital gain is taxed at preferential rates (0%, 15%, or 20%), regardless of your bracket. So the same $50,000 long-term gain costs $0-$10,000 in tax.

The bracket distinction drives much of tax-efficient investing strategy.

Bracket creep from capital gains

Adding income can push you into a higher bracket. A $50,000 short-term gain added to $150,000 income makes total taxable income $200,000. You are now in the 32% bracket, and the last portion of the gain is taxed at 32%, not your original 24%.

This “bracket creep” is a tax cost of realizing gains.

Married filing separately

Married couples can choose to file separately, which typically results in higher total tax (because the brackets are narrower). This is rarely optimal except in special cases (like isolating passive loss limitations). Consult a tax professional before filing separately.

Annual adjustments for inflation

Each year, the IRS adjusts bracket thresholds for inflation. In 2023, the 24% bracket for single filers was $100,525; in 2024, it is $100,525 (the bump varies by year based on inflation). These adjustments are announced each October for the next tax year.

Effective vs. marginal rate in brackets

Your marginal rate is the rate of your highest bracket (the bracket your last dollar of income falls into).

Your effective rate is your total tax divided by total income—a weighted average across all brackets, always lower than marginal.

Example: Taxable income $150,000 places you in the 24% bracket (marginal), but your effective rate is roughly 17% because lower income is taxed at lower rates.

Ordinary income vs. capital gains brackets

The seven brackets apply to ordinary income (wages, interest, ordinary dividends, short-term capital gains).

Long-term capital gains and qualified dividends have separate, preferential brackets (0%-20%), not shown here.

Example: You are in the 24% bracket for ordinary income. Your long-term capital gains rate is 15% (based on a different set of thresholds for long-term income).
