2026 Tax Changes Every American Needs to Know About

Tax year 2026 brings a meaningful set of changes that affect millions of American taxpayers. The One Big Beautiful Bill Act, signed into law on July 4, 2025, made many of the 2017 Tax Cuts and Jobs Act provisions permanent and introduced several new rules that will affect your tax planning starting this year. Here's what you need to know before you file.

Standard Deduction Amounts for 2026

The standard deduction continues to be inflation-adjusted annually. For 2026:

• Single filers: $15,350 (up from $14,600 in 2025)
• Married filing jointly: $30,700 (up from $29,200 in 2025)
• Head of household: $23,050

With over 90% of taxpayers taking the standard deduction, these inflation adjustments provide modest but real tax relief each year.

New Charitable Giving Floor

One of the most impactful changes for taxpayers who itemize is the new charitable giving floor introduced by the OBBBA. Before any charitable deduction is allowed, you must first "spend" 0.5% of your Adjusted Gross Income (AGI) on charitable contributions. For someone with a $100,000 AGI, the first $500 of charitable giving is non-deductible. For a $500,000 AGI earner, the first $2,500 disappears. This is a meaningful change for high-income itemizers who give modestly, but has little impact on those who give generously relative to their income.

SALT Deduction Cap Update

The $10,000 cap on State and Local Tax (SALT) deductions remains in place for 2026, made permanent by the OBBBA. This continues to be the most significant limitation for high-income taxpayers in high-tax states like California, New York, New Jersey, and Illinois. Various workarounds - like state-level pass-through entity (PTE) elections for business owners - remain available and should be discussed with a CPA.

Retirement Account Contribution Limits for 2026

• 401(k), 403(b), 457 plans: $23,500 (catch-up contribution of $7,500 for those 50+; new enhanced catch-up of $11,250 for ages 60–63 under SECURE 2.0)
• IRA (Traditional and Roth): $7,000 ($8,000 if 50+)
• HSA: $4,300 (individual), $8,550 (family)
• SEP-IRA: Up to $70,000 or 25% of compensation, whichever is less

Capital Gains Tax Rates for 2026

Long-term capital gains (assets held over one year) are taxed at 0%, 15%, or 20% depending on taxable income. For 2026:

• 0% rate: Taxable income up to $47,025 (single) / $94,050 (married filing jointly)
• 15% rate: Taxable income up to $518,900 (single) / $583,750 (married filing jointly)
• 20% rate: Above those thresholds

The 3.8% Net Investment Income Tax (NIIT) also applies to investment income for higher earners (MAGI above $200,000 single / $250,000 married), effectively raising the top rate on long-term gains to 23.8%.

Key Tax Deadlines for 2026

• April 15, 2026: Federal tax return due (or extension request). Also the deadline for 2025 IRA contributions.
• June 16, 2026: Second quarter estimated tax payment due
• September 15, 2026: Third quarter estimated tax payment due
• October 15, 2026: Extended return deadline

Proactive Tax Planning Moves for 2026

With rates locked in for the near term, 2026 is an excellent year for Roth conversions if you're in a lower tax bracket than you expect to be long-term. Tax-loss harvesting in taxable accounts can offset capital gains. And if you're self-employed, maximizing contributions to a Solo 401(k) or SEP-IRA before December 31 remains one of the most powerful tax reduction tools available. Don't wait until April to think about your 2026 taxes - the best opportunities require action before year-end.
