2026 Federal Tax Brackets: What Each Rate Actually Costs You
Why brackets matter — and why most people misread them
Federal income tax brackets cause more confusion per dollar than any other piece of US tax policy. The most common misreading: “I just got a raise that pushed me into the 24% bracket, so all my income is now taxed at 24%.” Wrong. The 24% only applies to the slice of income inside that bracket — every dollar below it is still taxed at the lower rates. Your marginal rate is the rate on your next dollar; your effective rate is the rate on your total income, which is always lower (unless your entire income happens to fall in the bottom bracket).
This guide gives you the 2026 brackets for single and married-filing-jointly filers, walks through the marginal-vs-effective distinction with a worked example, and covers the moving parts that determine which bracket your last dollar actually lands in: the standard deduction, above-the-line adjustments, and the bracket-stacking rules for capital gains and qualified dividends.
2026 brackets — single filers
| Bracket | Taxable income |
|---|---|
| 10% | $0 – $12,400 |
| 12% | $12,400 – $50,400 |
| 22% | $50,400 – $105,700 |
| 24% | $105,700 – $201,775 |
| 32% | $201,775 – $256,225 |
| 35% | $256,225 – $640,600 |
| 37% | Above $640,600 |
The bracket thresholds are adjusted annually for inflation under a permanent formula in the Internal Revenue Code (chained CPI). The seven-bracket structure itself — 10%, 12%, 22%, 24%, 32%, 35%, 37% — was made permanent by the One Big Beautiful Bill enacted in 2025; the previous sunset to pre-2018 rates that would have triggered after 2025 is now gone.
2026 brackets — married filing jointly
| Bracket | Taxable income |
|---|---|
| 10% | $0 – $24,800 |
| 12% | $24,800 – $100,800 |
| 22% | $100,800 – $211,400 |
| 24% | $211,400 – $403,550 |
| 32% | $403,550 – $512,450 |
| 35% | $512,450 – $768,700 |
| 37% | Above $768,700 |
The MFJ thresholds are double the single thresholds for the four lowest brackets, then taper. The top bracket kicks in 20% higher for MFJ than 2× single — a deliberate design choice to limit the marriage penalty for high-income couples.
The standard deduction does most of the work
The brackets above apply to taxable income, not gross income. To get from one to the other, most filers subtract the standard deduction. For 2026:
- Single: $16,100.
- Married filing jointly: $32,200.
- Head of household: $24,150.
The standard deduction was raised substantially in 2018 and has been moving up with inflation ever since. As of 2026 roughly 90% of filers take the standard deduction rather than itemizing, because itemized deductions (state and local taxes, mortgage interest, charitable giving) don’t typically exceed the standard amount.
The 2025 tax legislation also lifted the SALT cap from $10,000 to $40,000 for filers earning under the phaseout threshold. This brought itemizing back into play for higher-earning households in high-tax states; for most filers in low- and mid-tax states the standard deduction still wins. The SALT cap reverts to $10,000 from 2030 under the same legislation.
Worked example for a single filer earning $80,000:
- Gross income: $80,000.
- Less standard deduction: $80,000 − $16,100 = $63,900 taxable income.
- Taxable income hits the 22% bracket (which starts at $50,400 for singles).
That last point — taxable income, not gross — is why a $100,000 salary doesn’t put a single filer “in the 24% bracket”. Their taxable income is closer to $83,900, which falls in the 22% bracket.
Marginal vs effective — the worked example everyone needs
Take a single filer with $80,000 of gross wages, no above-the-line adjustments, standard deduction.
Taxable income: $80,000 − $16,100 = $63,900.
Walk the brackets:
- 10% × $12,400 = $1,240.
- 12% × ($50,400 − $12,400) = 12% × $38,000 = $4,560.
- 22% × ($63,900 − $50,400) = 22% × $13,500 = $2,970.
- Total federal income tax: $8,770.
This filer’s marginal rate is 22% — that’s the rate on their next dollar of wages until taxable income hits $105,700. Their effective rate is $8,770 / $80,000 = 10.96% of gross income, or $8,770 / $63,900 = 13.73% of taxable income.
When a financial commentator says “the average American pays about 14% in federal income tax”, they mean the effective rate on taxable income, calculated across all filers. The marginal rate matters for decisions about the next dollar (taking on overtime, claiming an additional deduction); the effective rate matters for sizing your overall federal-tax cost.
Above-the-line adjustments lower your bracket
A handful of contributions and deductions reduce adjusted gross income (AGI) before the standard deduction is applied. These are “above-the-line” — they help everyone, whether you itemize or not. The big ones:
- Traditional 401(k) contribution: up to $24,500 in 2026, plus $7,500 catch-up at 50+ and $11,250 at ages 60–63.
- Traditional IRA contribution: up to $7,500 in 2026, with income-based deductibility limits if you’re also covered by a workplace plan.
- HSA contribution: up to $4,400 self-only or $8,750 family in 2026 (you have to be enrolled in a qualifying high-deductible health plan).
- Half of self-employment tax if you’re a sole proprietor.
- Student loan interest: up to $2,500.
The effect on bracket arithmetic can be large. A $80,000-earning single filer who maxes a traditional 401(k) at $24,500 drops AGI to $55,500, taxable income to $39,400 — straight back into the 12% bracket. Federal tax falls from $8,770 to roughly $4,480.
This is the practical reason “what bracket am I in” matters less than “what bracket would I be in after I max my pre-tax accounts?”
Bracket stacking with capital gains and qualified dividends
Long-term capital gains (held over a year) and qualified dividends are taxed at separate, lower rates: 0%, 15% or 20% depending on total taxable income. They use the same income to determine which CG bracket you’re in, but they don’t compound with ordinary-income tax.
A common mistake is forgetting that ordinary income still “fills the brackets first” and capital gains “stack on top”. A single filer with $40,000 of W-2 wages and $20,000 of long-term capital gains has $60,000 of total income. The wage income, after the $16,100 standard deduction, is $23,900 — taxed at ordinary rates totalling about $2,628. The $20,000 of capital gains sits on top: the 0% LTCG threshold for singles in 2026 is $49,250 of taxable income; gains above that line are taxed at 15%. Here the capital gains stack from $23,900 up to $43,900, all still inside the 0% LTCG window — so zero federal tax on the $20,000 of gains.
The exact LTCG break points aren’t covered here — they’re in the US capital gains calculator — but the stacking principle is critical. People with significant long-term gains can sometimes plan their year to keep total taxable income under the 0% LTCG threshold and pay no federal tax on the gain.
Higher-income items: NIIT, AMT, the “donut hole”
Three additional things matter once you’re earning into the higher brackets:
- Net Investment Income Tax (NIIT): a 3.8% surcharge on net investment income (interest, dividends, capital gains, rental income) for filers with modified AGI above $200,000 single / $250,000 MFJ. It stacks on top of regular income tax and capital gains tax.
- Additional Medicare Tax: 0.9% on wages above the same NIIT thresholds, withheld by the employer once wages from that employer exceed $200,000 regardless of filing status. You may need to true up via the 1040 if you’re MFJ.
- AMT: the Alternative Minimum Tax still exists but its 2026 exemption is generous enough that fewer than 1% of filers pay it. It mainly hits higher-income filers with large state-tax deductions and certain incentive stock option exercises.
These three items add nuance to the simple bracket schedule, especially for households well into the 32%-and-up bands.
Frequently asked questions
Where can I find my exact marginal rate? Look at your taxable income on last year’s 1040 (Line 15) and find which bracket above it falls into. If you’re a wage earner with simple deductions, your bracket this year will usually be similar — a raise or extra income could push you up, a 401(k) increase could push you down.
Does the standard deduction reduce the brackets? It reduces the base the brackets apply to. The brackets themselves don’t move. So a $16,100 deduction for a single filer effectively makes the first $28,500 of gross income tax-free in 2026 ($16,100 standard deduction + $12,400 of 10% bracket — which is technically taxed at 10% but small enough most filers treat it as the bottom of the schedule).
How are bonuses taxed differently? Bonuses are subject to a 22% federal supplemental withholding rate (or 37% if the bonus exceeds $1m in a calendar year) for payroll-tax purposes. That’s a withholding rate, not the rate you actually owe — at year-end your bonus is added to ordinary wages and taxed at your real marginal rate. If 22% over-withholds (your marginal rate is 12%), you get the difference back as a refund. If it under-withholds (your marginal rate is 32%), you owe more.
Why does the federal income tax calculator show a number different from my paycheck withholding? Withholding is an estimate based on your W-4. Actual tax liability is calculated annually on your 1040 using the brackets above. The difference is the refund or amount due at filing. Adjust the W-4 if the gap is consistently large.
Do tax brackets apply to investment income? Ordinary interest and short-term capital gains are taxed at the ordinary brackets above. Long-term capital gains and qualified dividends have their own 0/15/20% rates with separate thresholds.
