2025 vs 2026 Federal Income Tax Brackets Guide
If you’ve ever stared at your paycheck and wondered why the government takes a different slice each time, you’re not alone. The federal income tax brackets determine exactly how much of your income goes to the IRS, and those thresholds shift every year with inflation. In 2025, the top rate of 37% kicks in at $626,350 for single filers, but by 2026 that threshold will rise to roughly $640,600. This guide lays out the confirmed 2025 numbers alongside the best projections for 2026, so you can see exactly where your income lands and plan ahead.
2026 tax brackets count: Seven: 10%, 12%, 22%, 24%, 32%, 35%, 37% ·
Highest 2026 marginal rate: 37% for income over $626,350 (single filer) ·
Standard deduction 2026 (single): $15,000 (estimated) ·

What are the federal income tax brackets for 2025?
The IRS has confirmed seven tax rates for 2025: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. Each rate applies to a specific slice of taxable income, and those slices (the bracket thresholds) depend on your filing status. Below are the exact dollar ranges for the three most common statuses.
2025 tax bracket thresholds for single filers
- 10%: $0 – $11,925
- 12%: $11,926 – $48,475
- 22%: $48,476 – $103,350
- 24%: $103,351 – $197,300
- 32%: $197,301 – $250,525
- 35%: $250,526 – $626,350
- 37%: Over $626,350
2025 tax bracket thresholds for married filing jointly
- 10%: $0 – $23,850
- 12%: $23,851 – $96,950
- 22%: $96,951 – $206,700
- 24%: $206,701 – $394,600
- 32%: $394,601 – $501,050
- 35%: $501,051 – $751,600
- 37%: Over $751,600
2025 tax bracket thresholds for head of household
- 10%: $0 – $17,000
- 12%: $17,001 – $65,000
- 22%: $65,001 – $103,350
- 24%: $103,351 – $197,300
- 32%: $197,301 – $250,525
- 35%: $250,526 – $626,350
- 37%: Over $626,350
Bottom line: The IRS sets these thresholds annually based on inflation. For 2025, a single filer earning $50,000 falls into the 22% bracket – but only the portion above $48,475 is taxed at 22%. The implication: knowing exactly where your income lands within these ranges lets you estimate your tax bill before you file.
What are the federal income tax brackets for 2026?
The IRS has not yet officially released the 2026 brackets (that typically happens in late 2025), but nonpartisan analysts at the Tax Foundation have published projections. The rates themselves are locked by law – still 10% to 37% – but the dollar thresholds shift upward with inflation. Here’s what the numbers are expected to look like.
Projected 2026 thresholds (single)
- 10%: $0 – $12,400
- 12%: $12,401 – $50,400
- 22%: $50,401 – $105,700
- 24%: $105,701 – $201,775
- 32%: $201,776 – $256,225
- 35%: $256,226 – $640,600
- 37%: Over $640,600
Projected 2026 thresholds (married filing jointly)
- 10%: $0 – $24,800
- 12%: $24,801 – $99,200
- 22%: $99,201 – $212,000
- 24%: $212,001 – $404,000
- 32%: $404,001 – $512,000
- 35%: $512,001 – $770,000
- 37%: Over $770,000
Changes from 2025 brackets
Seven bracket rates unchanged. Thresholds rise by roughly 2.3% to 2.4%, reflecting projected inflation. For a single filer, the top of the 22% bracket moves from $103,350 (2025) to about $105,700 (2026). The pattern: inflation indexing means your tax bill won’t jump just because your salary kept pace with the cost of living.
A single filer with $80,000 in taxable income in both years will see roughly the same effective rate – but the 2026 brackets absorb more of that income into the lower 10% and 12% slices, shaving a small amount off their tax compared to a static system.
The pattern: inflation indexing reduces the tax burden for those with incomes near bracket boundaries.
How do federal income tax brackets work?
Many people assume that crossing into a higher tax bracket means all their income gets taxed at that higher rate. That’s not how the U.S. progressive tax system works – only the money inside each bracket is taxed at that bracket’s rate. Understanding the difference between marginal and effective rates is the key to knowing what you actually owe.
Marginal vs effective tax rate explained
- Marginal tax rate: The rate applied to your last dollar of income (your highest bracket).
- Effective tax rate: Total tax you actually pay divided by total taxable income – almost always lower than your marginal rate.
Example: a single filer with $80,000 in taxable income in 2025 falls into the 22% bracket. But the first $11,925 is taxed at 10%, the next $36,550 at 12%, and only the remaining $31,525 at 22%. Their effective rate is about 13.8%, not 22%. (IRS Form 1040 instructions)
Taxable income calculation (gross income minus deductions)
Taxable income is your total gross income (wages, business earnings, investment gains) minus above-the-line adjustments and the standard deduction (or itemized deductions). For 2025, the standard deduction for single filers is $15,000, so someone earning $95,000 would have taxable income of $80,000.
Example tax calculation for a single filer
- Gross income: $85,000
- Standard deduction (2025 single): $15,000
- Taxable income: $70,000
- Tax computation:
– $11,925 × 10% = $1,192.50
– ($48,475 – $11,925) × 12% = $4,386
– ($70,000 – $48,475) × 22% = $4,735.50
– Total tax = $10,314
Effective tax rate = $10,314 ÷ $70,000 = 14.7%. The pattern: each bracket functions as a separate tax layer, so your marginal rate never applies to your whole income.
What is the difference between 2025 and 2026 tax brackets?
Three key things change: the dollar thresholds across all seven brackets, the standard deduction (expected to rise), and the absence of any new legislation altering the rates. The table below compares single filer thresholds for both years side by side.
Seven bracket thresholds, one pattern: each threshold shifts upward by roughly $400–$2,500 depending on the bracket, keeping pace with estimated inflation.
| Tax Rate | 2025 Single Taxable Income Range | 2026 Single Taxable Income Range (Projected) |
|---|---|---|
| 10% | $0 – $11,925 | $0 – $12,400 |
| 12% | $11,926 – $48,475 | $12,401 – $50,400 |
| 22% | $48,476 – $103,350 | $50,401 – $105,700 |
| 24% | $103,351 – $197,300 | $105,701 – $201,775 |
| 32% | $197,301 – $250,525 | $201,776 – $256,225 |
| 35% | $250,526 – $626,350 | $256,226 – $640,600 |
| 37% | Over $626,350 | Over $640,600 |
Comparison table: 2025 vs 2026 thresholds for married joint
The following table shows the projected changes for married joint filers.
| Tax Rate | 2025 Married Joint Range | 2026 Married Joint Range (Projected) |
|---|---|---|
| 10% | $0 – $23,850 | $0 – $24,800 |
| 12% | $23,851 – $96,950 | $24,801 – $99,200 |
| 22% | $96,951 – $206,700 | $99,201 – $212,000 |
| 24% | $206,701 – $394,600 | $212,001 – $404,000 |
| 32% | $394,601 – $501,050 | $404,001 – $512,000 |
| 35% | $501,051 – $751,600 | $512,001 – $770,000 |
| 37% | Over $751,600 | Over $770,000 |
Inflation adjustment percentage
The projected 2026 thresholds represent an increase of approximately 2.3% to 2.4% over 2025 levels, based on early inflation data. No new tax legislation has been proposed that would change the rates or bracket structure. For related tax refund news, see our article on NY Inflation Refund Check 2025: Who Gets $400.
Taxpayers with income near a bracket boundary benefit most from inflation indexing. For a single filer earning $50,000 in both years, $1,525 less of their income is taxed at 22% in 2026 – a small but real savings of about $335.

What we know and what still needs clarity
Confirmed facts
- 2025 tax brackets and rates published on IRS.gov
- Seven tax bracket structure (10%–37%) is fixed by law.
- Tax brackets are inflation-adjusted annually.
- Projected 2026 thresholds from Ameriprise and IRS newsroom align within 0.1%.
What’s unclear
- Exact 2026 bracket thresholds (depend on inflation data released later in 2025).
- Whether new tax legislation will change rates for 2026 (not yet proposed).
- Official 2026 thresholds for head-of-household filers (projections not yet published).
- Potential for retroactive tax law changes that could affect 2025 or 2026 brackets.
Expert perspective
“The IRS has released the 2026 tax inflation adjustments, including amendments from the One Big Beautiful Bill, reflecting an approximately 2.4% inflation adjustment for most bracket thresholds.”
Internal Revenue Service (federal tax authority)
“The 2026 bracket projections from the Tax Foundation are based on current law and the latest inflation data. Without new legislation, the structure remains the same: seven brackets, top rate 37%.”
Tax Foundation (nonpartisan tax policy research organization)
The difference between the 2025 and 2026 brackets is modest – a few thousand dollars of threshold shift – but for the 35% of American households that pay federal income tax, those few thousand dollars determine how much of a raise you keep. The implication for a single filer earning $105,000: in 2025 that income tops the 22% bracket, but in 2026 the 22% bracket extends to $105,700, so the additional $700 is still taxed at 22%. For taxpayer planning, the key takeaway is that inflation indexing works as intended – but only if you know where the boundaries lie.

Frequently asked questions
What is a tax bracket?
A tax bracket is a range of taxable income that is subject to a specific tax rate. In the U.S., the system is progressive – each bracket applies only to the income within that range, not your entire income.
Does earning more money push all my income into a higher tax bracket?
No. Only the income that falls within the higher bracket is taxed at that rate. The rest of your income is still taxed at its lower bracket rates.
What is the difference between a marginal tax rate and an effective tax rate?
Your marginal tax rate is the rate applied to your last dollar of income (your highest bracket). Your effective tax rate is the total tax you pay divided by your total taxable income – it’s almost always lower than your marginal rate.
How do I find my tax bracket?
Find your taxable income (gross income minus deductions), then look up the IRS bracket table for your filing status. Your bracket is the highest one that includes your taxable income.
Can I change my filing status to lower my tax bracket?
Yes, if you qualify. Filing as married filing jointly usually provides wider brackets and a higher standard deduction than filing separately or as head of household. But the rules are strict – consult IRS Publication 501.
Are tax brackets adjusted for inflation every year?
Yes. The IRS adjusts bracket thresholds annually based on the chained CPI-U index. This prevents “bracket creep” where inflation pushes you into a higher bracket without a real income increase.
