Capital Gains Tax Rates 2026: Brackets, Thresholds, and Planning Strategies

Long-term capital gains are taxed at 0%, 15%, or 20% depending on your taxable income. Add the 3.8% Net Investment Income Tax (NIIT) for high earners, and the effective top rate reaches 23.8% before state taxes. Understanding exactly where each threshold falls is the difference between a zero-tax stock sale and a five-figure tax bill.

2026 Long-Term Capital Gains Brackets

Long-term capital gains apply to assets held longer than one year. Short-term gains (held one year or less) are taxed as ordinary income at your marginal rate.

Filing Status	0% Rate	15% Rate	20% Rate
Single	Up to ~$48,350	~$48,351 - ~$533,400	Over ~$533,400
Married Filing Jointly	Up to ~$96,700	~$96,701 - ~$600,050	Over ~$600,050
Head of Household	Up to ~$64,750	~$64,751 - ~$566,700	Over ~$566,700

These thresholds are based on taxable income, not gross income. Your standard deduction (~$15,000 single / ~$30,000 MFJ) reduces your AGI before these brackets apply.

The 0% Bracket: Your Most Powerful Tool

The 0% rate is not limited to low earners. Retirees drawing from a mix of Social Security, Roth withdrawals, and taxable accounts often have taxable income well below the threshold. A married couple with ~$96,700 in taxable income can realize long-term gains completely tax-free at the federal level.

Practical scenarios where the 0% rate applies:

Early retirees before Social Security: Living off savings with minimal taxable income
Gap years or sabbaticals: A year between jobs with little W-2 income
Business owners in a down year: Low pass-through income
Students or part-time workers: Income below the threshold

Strategy: If you are in any of these situations, consider harvesting gains deliberately — selling appreciated investments and immediately rebuying them to reset your cost basis at the current market value. This is the opposite of tax-loss harvesting, and it is completely legal.

Net Investment Income Tax (NIIT): The 3.8% Surcharge

The NIIT adds 3.8% on top of your capital gains rate if your modified adjusted gross income exceeds:

Filing Status	NIIT Threshold
Single	~$200,000
Married Filing Jointly	~$250,000
Head of Household	~$200,000

These thresholds are not indexed for inflation and have remained unchanged since 2013. As incomes rise, more taxpayers fall into NIIT territory each year.

The NIIT applies to: Capital gains, dividends, rental income, royalties, passive business income, and interest (excluding tax-exempt bond interest).

The NIIT does not apply to: Wages, self-employment income, Social Security, distributions from qualified retirement plans (401(k), IRA), or active business income.

State Capital Gains Taxes

Federal rates are only part of the picture. States add their own layer:

Category	States	Effective Additional Rate
No state income tax	AK, FL, NV, NH, SD, TN, TX, WA**, WY	0%
Low state rate (under 5%)	AZ, CO, IN, MI, ND, PA, UT	~2.5% - 4.95%
Moderate (5-8%)	GA, IL, KY, MA, OH, VA, WI	~5% - 7.65%
High (8%+)	CA, HI, MN, NJ, NY, OR	~8% - 13.3%

*NH and TN tax interest and dividends only. **WA imposes a 7% capital gains tax on gains exceeding $270,000.

A California resident in the 20% federal bracket with NIIT pays an effective combined rate of approximately 37.1% on long-term gains (20% + 3.8% + 13.3%).

Short-Term vs. Long-Term: The Holding Period Matters

Short-term capital gains are taxed as ordinary income. For a taxpayer in the 32% federal bracket plus NIIT plus California state tax, the effective rate on a short-term gain is approximately 49.1% compared to approximately 37.1% on a long-term gain — a 12 percentage point difference.

Rule of thumb: If you are considering selling an appreciated asset and you are within a few months of the one-year mark, the tax savings from waiting almost always outweigh the market risk of holding.

Capital Gains on Specific Assets

Real Estate

The home sale exclusion shelters $250,000 (single) or $500,000 (MFJ) of gain on a primary residence. Investment property does not qualify for this exclusion but can defer gains through a 1031 exchange.

Collectibles

Art, antiques, coins, and precious metals are taxed at a maximum 28% rate regardless of holding period — higher than the standard 20% maximum for stocks and bonds.

Qualified Small Business Stock (QSBS)

Under Section 1202, gains on qualified small business stock held more than five years may be excluded up to $10 million or 10 times the adjusted basis. This is one of the most valuable tax exclusions in the code for founders and early employees.

Tax-Loss Harvesting to Offset Gains

When you do realize gains, tax-loss harvesting lets you sell underwater investments to offset those gains dollar-for-dollar. Excess losses offset up to $3,000 of ordinary income per year, with unlimited carryforward.

The wash sale rule: You cannot buy a “substantially identical” security within 30 days before or after the sale. Buy a similar but not identical fund (different index, different provider) to maintain your market exposure.

Planning Strategies by Income Level

Under the 0% threshold: Harvest gains each year to reset your basis. Every dollar of gain realized in the 0% bracket is a dollar that will never be taxed.

In the 15% bracket: This is where most Americans fall. Focus on holding assets for over a year and timing sales to avoid bracket creep. Consider bunching income and gains in alternating years.

Near the 20% / NIIT thresholds: Manage MAGI carefully. Roth conversions, charitable contributions, and timing of business income can keep you below the NIIT threshold. A $1 increase in MAGI past the threshold does not trigger NIIT on all investment income — it applies only to the lesser of net investment income or the excess over the threshold.

Key Takeaways

The 0% long-term capital gains rate applies to taxable income up to approximately $48,350 (single) / ~$96,700 (MFJ) in 2026
The NIIT adds 3.8% for MAGI above ~$200,000 (single) / ~$250,000 (MFJ), pushing the top effective federal rate to 23.8%
State taxes can add 0% to 13.3% depending on your state, making the combined rate as high as approximately 37%
Holding assets for over one year is the single most impactful tax move for investors — short-term rates can be 10-15 percentage points higher
Tax-loss harvesting, 0% bracket harvesting, and Roth conversions are the primary tools for managing capital gains exposure
