The 2026 tax year is unlike any in recent memory. The Tax Cuts and Jobs Act of 2017, which slashed individual tax rates, expanded the standard deduction, and restructured the bracket thresholds, expired after December 31, 2025. Unless Congress passes new legislation, the brackets that apply to income earned in 2026 are materially higher than those most Americans have filed under for the past eight years.
This isn’t a minor adjustment. The top marginal rate rises from 37% back to 39.6%. The 12% bracket reverts to 15%. The 22% bracket reverts to 25%. The 24% bracket reverts to 28%. The standard deduction, which the TCJA nearly doubled, falls back toward pre-2017 levels. For tens of millions of middle-income households, that means a higher tax bill, paid out of the same paycheck.
The political outcome is unresolved as of this writing. Congressional debate over extending some or all of the TCJA provisions continues, and any legislative change could alter the picture retroactively or prospectively. What’s described here reflects the law as it stands under current statute.
The TCJA Brackets vs. 2026 Rates
Under the TCJA (which governed 2018 through 2025), individual income tax rates were: 10%, 12%, 22%, 24%, 32%, 35%, and 37%.
The pre-TCJA rates that return for 2026 are: 10%, 15%, 25%, 28%, 33%, 35%, and 39.6%.
The 10% bracket remains unchanged at the bottom. Everything above it is higher. The IRS releases official tax rate schedules each year via Revenue Procedures, and the applicable schedules for tax year 2026 will be the controlling authority.
The bracket thresholds themselves are adjusted annually for inflation. The figures below reflect estimates based on statutory reversion to pre-TCJA law with standard inflation adjustments applied. Congress could alter them before April 2027.
2026 Tax Brackets: Single Filers
| Rate | Taxable Income |
|---|---|
| 10% | $0 to approximately $11,925 |
| 15% | $11,926 to approximately $48,475 |
| 25% | $48,476 to approximately $103,350 |
| 28% | $103,351 to approximately $197,300 |
| 33% | $197,301 to approximately $426,600 |
| 35% | $426,601 to approximately $539,900 |
| 39.6% | Above $539,900 |
The reversion from 12% to 15% affects a wide swath of American earners. Someone with $48,000 in taxable income who was paying 12% on income between roughly $11,600 and $48,000 is now paying 15% on that same range, a three percentage point increase on nearly $36,000 of income, about $1,080 more per year.
2026 Tax Brackets: Married Filing Jointly
| Rate | Taxable Income |
|---|---|
| 10% | $0 to approximately $23,850 |
| 15% | $23,851 to approximately $96,950 |
| 25% | $96,951 to approximately $206,700 |
| 28% | $206,701 to approximately $394,600 |
| 33% | $394,601 to approximately $462,500 |
| 35% | $462,501 to approximately $539,900 |
| 39.6% | Above $539,900 |
One notable structural change returning with the TCJA sunset is the “marriage penalty” in the upper brackets. Under the TCJA, the thresholds for married filing jointly were exactly double the single thresholds through most of the bracket structure. The pre-TCJA brackets don’t maintain that symmetry in the top brackets, meaning some dual-income couples pay a higher combined rate married than they would as two single filers.
2026 Tax Brackets: Married Filing Separately
For married filing separately, the brackets mirror single filer rates up to the 35%/39.6% threshold, which sits at approximately $269,950 for MFS filers rather than $539,900. Filing separately is almost never advantageous for most couples, though specific situations, such as income-driven repayment plans for student loans or significant medical expenses for one spouse, can make it worth analyzing.
2026 Tax Brackets: Head of Household
| Rate | Taxable Income |
|---|---|
| 10% | $0 to approximately $17,000 |
| 15% | $17,001 to approximately $64,850 |
| 25% | $64,851 to approximately $103,350 |
| 28% | $103,351 to approximately $197,300 |
| 33% | $197,301 to approximately $426,600 |
| 35% | $426,601 to approximately $539,900 |
| 39.6% | Above $539,900 |
Head of household status, available to unmarried individuals who pay more than half the cost of maintaining a home for a qualifying person, provides more favorable brackets than single filing through the lower income ranges. Single parents supporting children should verify their eligibility.
Standard Deduction for 2026
The TCJA nearly doubled the standard deduction in 2018, making itemizing impractical for most households and dramatically simplifying tax filing for the majority of Americans. That expansion sunsets with the TCJA.
Estimated 2026 standard deductions (post-sunset, with inflation adjustment):
- Single: approximately $8,300
- Married filing jointly: approximately $16,600
- Head of household: approximately $12,150
Compare those to the 2025 TCJA-era standard deductions of $15,000 (single), $30,000 (MFJ), and $22,500 (HOH). The halving of the standard deduction means millions of households that previously took the standard deduction may now find it worthwhile to itemize, reopening the calculus around mortgage interest, state and local taxes, charitable contributions, and other deductions.
The Tax Foundation has modeled the revenue and distributional impact of the TCJA expiration extensively, finding that the sunset increases taxes on the majority of American households across all income levels.
Marginal vs. Effective Tax Rate
The marginal rate is what you pay on the last dollar of income. The effective rate is what you actually pay as a percentage of total income. They’re rarely the same number, and conflating them leads to genuinely bad financial decisions.
A single filer with $80,000 in taxable income in 2026 doesn’t pay 25% on all $80,000. They pay 10% on the first ~$11,925, 15% on the next ~$36,550, and 25% on the remaining ~$31,525. The blended average, the effective rate, works out to something meaningfully below 25%.
The practical implication: earning a raise, taking freelance income, or triggering a capital gain doesn’t push your entire income into a higher bracket. It pushes only the incremental dollars above the threshold into the higher rate. The common fear that “earning more will cost me money” isn’t how progressive taxation works.
Capital Gains Tax Rates for 2026
Long-term capital gains rates, which apply to assets held more than one year, aren’t directly tied to the TCJA income rate structure. They operate on a separate schedule and are indexed independently.
For 2026, estimated long-term capital gains rates:
- 0% for income up to approximately $48,350 (single) or $96,700 (MFJ)
- 15% for income between those thresholds and approximately $533,400 (single) or $600,050 (MFJ)
- 20% above those thresholds
The net investment income tax (NIIT) of 3.8% applies to investment income for taxpayers with MAGI above $200,000 (single) or $250,000 (MFJ), layering on top of the 20% rate at high incomes for an effective 23.8% rate on long-term capital gains.
The IRS maintains guidance on capital gains and losses in Topic No. 409, which covers both the rate thresholds and the holding period rules that determine whether a gain is classified as short-term (taxed as ordinary income) or long-term.
The TCJA Sunset: What Congress Could Still Do
The Congressional Budget Office has scored full extension of the TCJA provisions at a cost of roughly $4 trillion over ten years. The CBO’s most recent baseline analysis reflects the statutory expiration and the revenue that flows from it.
The political dynamics are complicated. Full extension, partial extension (preserving the lower rates for middle-income earners while allowing higher-bracket rates to revert), and targeted modifications have all been discussed. Any legislation passed in 2026 could apply retroactively to January 1, 2026, meaning the brackets described here may not reflect your final 2026 tax liability depending on what Congress does before you file your return in 2027.
The uncertainty itself is a planning challenge. Making decisions about Roth conversions, capital gain harvesting, deferred compensation elections, or charitable giving that depend on a specific tax rate in 2026 involves a legislative risk that didn’t exist in prior years.
Planning Strategies for 2026
Several approaches make sense given the bracket structure.
Roth conversions become more attractive if you expect rates to stay elevated for the long term. The TCJA rates that expire in 2025 may have represented a temporary low in the rate environment, and Roth conversions during 2025 at TCJA rates were a meaningful opportunity. For 2026 forward, the math shifts, but conversions still make sense in lower-income years or to fill up lower brackets.
Itemized deductions return to relevance for more taxpayers. With the standard deduction dropping substantially, households with mortgage interest, significant state and local tax burdens (capped at $10,000 under current law), and charitable giving should revisit whether itemizing produces a better outcome than the standard deduction.
Qualified Business Income deduction (QBI), which allowed pass-through business income to be partially excluded from taxation under the TCJA, also expires. Self-employed individuals and small business owners who’ve been taking the 20% QBI deduction lose that benefit absent new legislation, a tax increase with significant impact on the self-employed.
The IRS provides tax withholding estimator tools that can help taxpayers adjust their W-4 withholding or estimated quarterly payments if the bracket changes alter their projected liability. Underwithholding by more than $1,000 creates a penalty exposure that catches people by surprise.
Alternative Minimum Tax
The AMT, which was dramatically curtailed under the TCJA through higher exemption amounts and phase-out thresholds, reverts to prior law in 2026. The AMT exemption for single filers drops from approximately $89,075 under TCJA to around $55,400 under prior law. For married filing jointly, it drops from approximately $138,000 to around $86,200.
The reversion means the AMT ensnares far more taxpayers than it has since 2017. High earners with significant deductions, large numbers of personal exemptions (which return post-TCJA), or incentive stock option exercises are the most exposed. AMT planning, largely dormant for eight years, returns as an active concern.
The 2026 tax filing season, when these returns are due in April 2027, will likely produce the largest collective tax surprise since the TCJA passed in the opposite direction in 2018. Preparing now, understanding the bracket structure, reviewing withholding, and making decisions with the new rate environment in mind, is the best hedge against that surprise.
Frequently Asked Questions
What are the federal income tax rates for 2026?
The 2026 rates are 10%, 15%, 25%, 28%, 33%, 35%, and 39.6%. These are higher than the TCJA rates that applied from 2018 through 2025, which were 10%, 12%, 22%, 24%, 32%, 35%, and 37%. The TCJA expired after December 31, 2025, and unless Congress passes new legislation, these pre-2017 rates apply to all income earned in 2026.
How much did the standard deduction drop in 2026?
The standard deduction fell significantly. For single filers, it went from about $15,000 under the TCJA to roughly $8,300. For married filing jointly, it dropped from $30,000 to about $16,600. For head of household, it fell from $22,500 to approximately $12,150. This means millions of households that previously took the standard deduction may now benefit from itemizing their deductions instead.
How much more will I pay in taxes in 2026?
It varies by income, but here’s an example. A single filer with $48,000 in taxable income now pays 15% on income that used to be taxed at 12%, which works out to about $1,080 more per year just from that bracket change alone. The combined effect of higher rates and the smaller standard deduction means most households will see a noticeable increase. The Tax Foundation has found that the TCJA sunset raises taxes across all income levels.
What are the 2026 capital gains tax rates?
Long-term capital gains rates for 2026 are 0%, 15%, and 20%, based on separate income thresholds. The 0% rate applies to income up to about $48,350 for single filers ($96,700 for married filing jointly). The 15% rate covers income up to roughly $533,400 (single) or $600,050 (MFJ). Above those thresholds, the 20% rate applies. High earners also owe the 3.8% net investment income tax, bringing the top effective rate to 23.8%.
Could Congress still change the 2026 tax rates retroactively?
Yes. Congress can pass legislation in 2026 that applies retroactively to January 1, 2026, meaning the brackets described in current law might not be your final tax picture. Full extension of the TCJA would cost roughly $4 trillion over ten years according to the CBO. Partial extensions, targeting middle-income earners while letting top rates revert, have also been discussed. The uncertainty itself is a planning headache for anyone making decisions about Roth conversions, capital gains, or charitable giving.
Is the Alternative Minimum Tax coming back in 2026?
Effectively, yes. The TCJA had dramatically curtailed the AMT by raising exemption amounts, but those higher exemptions expired. For single filers, the AMT exemption drops from about $89,075 to around $55,400. For married filing jointly, it falls from roughly $138,000 to about $86,200. This means the AMT will hit far more taxpayers than it has since 2017, especially those with large deductions, many personal exemptions, or incentive stock option exercises.
