IRS 2026 Inflation Adjustments: Tax Brackets, Contribution Limits, and Phase-Outs
Every January, the IRS announces inflation adjustments that affect tax brackets, retirement contribution limits, phase-out ranges, and dozens of other tax numbers. These adjustments impact your taxes, retirement planning, and investment strategy. Miss them, and you could overpay taxes or miss contribution opportunities. Here's a comprehensive reference guide to all the key 2026 IRS inflation adjustments you need to know.
2026 Federal Income Tax Brackets
The tax rates remain the same (10%, 12%, 22%, 24%, 32%, 35%, 37%), but the income thresholds where rates change are adjusted annually for inflation. Here are the 2026 brackets:
2026 Tax Brackets: Single Filers
| Tax Rate | Income Range | Federal Tax |
|---|---|---|
| 10% | $0 - $11,550 | Up to $1,155 |
| 12% | $11,551 - $47,150 | $1,155 + 12% of excess |
| 22% | $47,151 - $100,525 | $5,430 + 22% of excess |
| 24% | $100,526 - $191,950 | $17,536 + 24% of excess |
| 32% | $191,951 - $243,725 | $39,110 + 32% of excess |
| 35% | $243,726 - $609,350 | $55,178 + 35% of excess |
| 37% | $609,351+ | $186,601 + 37% of excess |
Takeaway: A single filer earning $100,000 pays 22% only on income from $47,151 to $100,000, NOT 22% on all $100,000.
2026 Tax Brackets: Married Filing Jointly (MFJ)
| Tax Rate | Income Range | Federal Tax |
|---|---|---|
| 10% | $0 - $23,200 | Up to $2,320 |
| 12% | $23,201 - $94,300 | $2,320 + 12% of excess |
| 22% | $94,301 - $201,050 | $10,852 + 22% of excess |
| 24% | $201,051 - $383,900 | $34,337 + 24% of excess |
| 32% | $383,901 - $487,450 | $78,221 + 32% of excess |
| 35% | $487,451 - $731,200 | $111,818 + 35% of excess |
| 37% | $731,201+ | $196,468 + 37% of excess |
Takeaway: Married couples benefit from doubled income thresholds compared to singles. The "marriage penalty" is minimized, though it still exists at high incomes.
2026 Tax Brackets: Head of Household
| Tax Rate | Income Range | Federal Tax |
|---|---|---|
| 10% | $0 - $17,400 | Up to $1,740 |
| 12% | $17,401 - $66,400 | $1,740 + 12% of excess |
| 22% | $66,401 - $112,650 | $6,588 + 22% of excess |
| 24% | $112,651 - $191,950 | $16,711 + 24% of excess |
| 32% | $191,951 - $243,725 | $36,951 + 32% of excess |
| 35% | $243,726 - $609,350 | $55,019 + 35% of excess |
| 37% | $609,351+ | $186,600 + 37% of excess |
Takeaway: Head of Household brackets fall between Single and MFJ, benefiting single parents and qualifying widows.
2026 Standard Deduction Amounts
| Filing Status | 2026 Standard Deduction |
|---|---|
| Single | $15,000 |
| Married Filing Jointly | $30,000 |
| Married Filing Separately | $15,000 |
| Head of Household | $22,500 |
| Qualifying Widow(er) | $30,000 |
| Age 65+ (additional) | |
| Single or HOH | +$2,000 - $2,500 |
| MFJ (one spouse 65+) | +$1,550 |
| MFJ (both spouses 65+) | +$3,100 |
Takeaway: The standard deduction increased from 2025 due to inflation. For seniors (age 65+), the additional deduction also increased.
2026 Capital Gains Tax Rates
Long-term capital gains (assets held over 1 year) are taxed at preferential rates:
Long-Term Capital Gains Brackets
| Rate | Single | MFJ | HOH |
|---|---|---|---|
| 0% | $0 - $47,025 | $0 - $94,050 | $0 - $62,975 |
| 15% | $47,026 - $518,900 | $94,051 - $583,750 | $62,976 - $551,350 |
| 20% | $518,901+ | $583,751+ | $551,351+ |
Takeaway: A married couple earning $200,000 in long-term capital gains pays 0% if they have no other income, 15% on gains between $94,050 and $200,000 (if applicable based on other income), and potentially 20% on very high gains.
Net Investment Income Tax (NIIT): Additionally, if your Modified Adjusted Gross Income exceeds $200,000 (single) or $250,000 (MFJ), you pay an additional 3.8% tax on net investment income. This is ON TOP of the capital gains rate.
2026 Retirement Contribution Limits
401(k), 403(b), and 457 Limits
| Category | 2026 Limit |
|---|---|
| Annual employee deferral | $23,500 |
| Age 50+ catch-up | +$7,500 |
| Age 60-63 super catch-up (new)* | +$11,250 |
| Total possible at age 60-63 | $42,250 |
| Employer contribution limit | $69,000 (total) |
*The age 60-63 super catch-up is new under SECURE Act 2.0. Those aged 60-63 can contribute $11,250 extra, while those 50-59 get $7,500 extra. At age 64, it drops back to $7,500.
Takeaway: A 61-year-old can contribute $23,500 + $11,250 = $34,750 to their 401(k), nearly double the regular limit. This is a powerful catch-up window that lasts only 4 years (ages 60-63).
Traditional and Roth IRA Limits
| Category | 2026 Limit |
|---|---|
| Annual contribution (under 50) | $7,000 |
| Annual contribution (age 50+) | $8,000 |
| Roth IRA income phase-out (single) | $146,000 - $161,000 |
| Roth IRA income phase-out (MFJ) | $230,000 - $240,000 |
| Traditional IRA deduction phase-out (single, covered by 401k)* | $77,000 - $87,000 |
| Traditional IRA deduction phase-out (MFJ, one spouse covered)* | $230,000 - $240,000 |
*Depends on whether you have access to a workplace retirement plan.
Takeaway: If you earn over $161,000 (single) or $240,000 (MFJ), you cannot directly contribute to a Roth IRA. However, the "backdoor Roth" strategy (contribute to traditional IRA, then convert to Roth) remains available if you have no other traditional IRA balances.
Employer Sponsored Plan Limits
| Plan Type | 2026 Limit |
|---|---|
| SEP-IRA | Lesser of 25% of net self-employment income or $69,000 |
| Solo 401(k) | $23,500 employee deferral + 25% of net self-employment income, max $69,000 total |
| SIMPLE IRA | $16,500 employee deferral + 3% employer match or 2% non-elective contribution |
| HSA (individual coverage) | $4,300 |
| HSA (family coverage) | $8,550 |
Takeaway: Self-employed people can save more in a SEP-IRA or Solo 401(k) than employees can in a regular 401(k) due to employer contribution allowances.
2026 Earned Income Tax Credit (EITC)
The EITC is a refundable tax credit for low to moderate-income working people. The amounts and phase-outs are adjusted annually:
| Category | 2026 Maximum Credit | Income Phase-Out (MFJ) |
|---|---|---|
| No qualifying children | $1,738 | $29,666 |
| One qualifying child | $3,733 | $49,162 |
| Two qualifying children | $6,105 | $54,909 |
| Three or more children | $7,286 | $57,838 |
Takeaway: Families with children earning under $50,000-60,000 may qualify for substantial EITC refunds (up to $7,286 for 3+ children). Many eligible families leave money on the table by not claiming it.
2026 Child Tax Credit
| Item | 2026 Amount |
|---|---|
| Per child credit (age 0-16) | $2,000 |
| Parent's SSN/ITIN required | Yes, to claim credit |
| Income phase-out begins (single) | $400,000 |
| Income phase-out begins (MFJ) | $600,000 |
| Reduction rate (over threshold) | $50 per $1,000 over limit |
Takeaway: High earners face a phase-out. A couple earning $650,000 with $600,000 threshold loses $50 × [($650,000 - $600,000) / $1,000] = $2,500 in child tax credits (if they would qualify for any).
2026 Alternative Minimum Tax (AMT)
The AMT is a parallel tax system for high earners. If your AMT exceeds your regular income tax, you pay the higher amount:
| Category | 2026 Amount |
|---|---|
| AMT exemption (single) | $85,750 |
| AMT exemption (MFJ) | $133,300 |
| AMT exemption phase-out (single) | $578,650+ |
| AMT exemption phase-out (MFJ) | $868,500+ |
| AMT tax rate | 26% / 28% |
Takeaway: The AMT is primarily a concern for high earners (over $200,000) with significant deductions (SALT, depreciation, exercise of stock options). For most Americans, the AMT does not apply.
2026 Income Phase-Outs and Limitations
Itemized Deduction Phase-Out (Pease Limitation)
High earners see their itemized deductions reduced:
| Filing Status | Income Threshold |
|---|---|
| Single | $213,300 |
| MFJ | $426,600 |
| HOH | $213,300 |
Reduction: Itemized deductions are reduced by 3% of income above the threshold (capped at 80% reduction). This effectively increases taxes for high earners.
Medical Expense Deduction Threshold
Only medical expenses exceeding 7.5% of AGI are deductible. This threshold has NOT changed since 2013.
Passive Activity Loss Limitations
Losses from passive activities (real estate, partnerships) are limited to $25,000 for those filing single/MFJ under certain income levels. The limit phases out between:
- Single: $150,000 - $200,000 AGI
- MFJ: $150,000 - $200,000 AGI
2026 Qualified Business Income (QBI) Deduction
The QBI deduction allows up to 20% of qualified business income to be deducted:
| Item | 2026 Amount |
|---|---|
| Deduction percentage | 20% of QBI |
| SSBT phase-out threshold (single) | $184,550 |
| SSBT phase-out threshold (MFJ) | $369,100 |
| W-2 wage limitation (SSBT owners) | 50% of W-2 wages paid |
Takeaway: Business owners under the phase-out threshold get the full 20% deduction. Those above the threshold (if they're in a Specified Service Trade or Business) face limitations based on W-2 wages paid to employees.
2026 Gift Tax and Estate Tax Exemptions
| Category | 2026 Amount |
|---|---|
| Annual gift tax exclusion (per person) | $19,000 |
| Lifetime estate/gift tax exemption (single) | $13,900,000 |
| Lifetime estate/gift tax exemption (MFJ) | $27,800,000 |
| Generation-skipping transfer (GST) tax exemption | $13,900,000 |
| Top estate tax rate | 40% |
Takeaway: You can give away $19,000/person/year indefinitely without using your lifetime exemption. The lifetime exemption (used at death) is so high that very few families owe federal estate tax.
2026 Self-Employment Tax Threshold and Rate
| Category | 2026 Amount |
|---|---|
| Self-employment income threshold (Schedule C) | $400 |
| SE tax rate | 15.3% (12.4% Social Security + 2.9% Medicare) |
| Social Security wage cap | $168,600 |
| Medicare tax (no cap) | 2.9% on all net SE income |
| Additional Medicare tax (high earners) | 0.9% on wages/SE income over $200,000 (single) / $250,000 (MFJ) |
Takeaway: Self-employed individuals pay SE tax on all net profit down to $400. The 12.4% Social Security portion applies only to earnings up to $168,600 (the wage cap), but the 2.9% Medicare portion applies to all earnings.
2026 Medicare Premium Thresholds (IRMAA)
Income-Related Monthly Adjustment Amounts (IRMAA) for Medicare beneficiaries are based on Modified Adjusted Gross Income from 2 years prior:
| Income Level (2024 MAGI) | Part B Premium (2026) |
|---|---|
| ≤$106,000 (single) | $185/month |
| $106,001 - $133,000 | $259/month |
| $133,001 - $167,000 | $370/month |
| $167,001 - $200,000 | $480/month |
| $200,001+ | $591/month |
Takeaway: There's a cliff effect with Medicare premiums. One dollar over a threshold can trigger hundreds of dollars in additional premiums. Consider Roth conversions and tax-loss harvesting in years before Medicare enrollment.
2026 Social Security Thresholds
| Category | 2026 Amount |
|---|---|
| Earnings test limit (under FRA) | $22,320/year |
| Reduction (earnings over limit) | $1 benefits for every $2 earned |
| Full Retirement Age (born 1960+) | 67 years |
| COLA increase for 2026 | 2.5% |
| Average retired worker benefit | ~$1,955/month (after 2.5% COLA) |
Takeaway: If you claim Social Security before Full Retirement Age and earn over $22,320/year, your benefits are reduced. At Full Retirement Age, there's no reduction for any earnings.
Key Takeaways
2026 tax brackets increased 2-4% from 2025 due to inflation; high earners may find themselves in higher marginal brackets than they expect.
The 401(k) limit is $23,500 (up from prior years), plus a $7,500 catch-up at 50+ and a $11,250 super catch-up at ages 60-63.
Standard deductions increased to $15,000 (single) / $30,000 (MFJ), reducing the number of people who benefit from itemization.
Long-term capital gains rates (0% / 15% / 20%) are separate from ordinary income rates and remain favorable for patient investors.
The EITC provides substantial refunds for low-income families with children—up to $7,286 for three or more kids.
SALT and other high earner deductions face phase-outs and limitations for those earning over $200,000-$400,000.
Self-employment tax, IRMAA Medicare premiums, and NIIT all affect high earners differently and require coordinated planning.
For detailed tax planning, use these numbers with a CPA or tax software to model your specific situation in 2026. Even small changes in income or deductions can push you into different tax brackets or trigger phase-outs.
