Short-Term vs. Long-Term Capital Gains

When you sell an asset for more than you paid for it, the profit is a capital gain. How it’s taxed depends entirely on how long you held the asset:

Short-term: Held 12 months or less → taxed as ordinary income at your regular marginal rate (up to 37%)
Long-term: Held more than 12 months → taxed at preferential lower rates (0%, 15%, or 20%)

This distinction is one of the most important and actionable rules in the entire tax code. Simply holding an appreciated asset for one day beyond the 12-month mark can substantially reduce your tax bill.

Example: You buy stock for $10,000 and sell it for $25,000 — a $15,000 gain.

If you held it 11 months: taxed at your ordinary rate. In the 22% bracket: $3,300 tax.
If you held it 13 months: taxed at the preferential 15% long-term rate: $2,250 tax.
If your income is low enough for the 0% rate: $0 tax.

2026 Long-Term Capital Gains Tax Rates

Tax Rate	Single Filer Taxable Income	Married Filing Jointly
0%	$0 – $48,350	$0 – $96,700
15%	$48,351 – $533,400	$96,701 – $600,050
20%	Over $533,400	Over $600,050

The 0% rate is one of the most underutilized opportunities in tax planning. If you are in the 10% or 12% ordinary income bracket — meaning total taxable income under ~$47,150 (single) or ~$94,300 (MFJ) — you can often realize long-term capital gains at zero federal tax. This is particularly powerful for:

Retirees drawing down investments
Low-income years (career breaks, part-time work)
Strategic “gain harvesting” before income rises

2026 Short-Term Capital Gains Tax Rates

Short-term capital gains are taxed at ordinary income rates — the same brackets as your salary. See 2026 Tax Brackets for the full table. In summary:

Ordinary Tax Rate	Applies When Taxable Income (Single)
10%	Up to $12,400
12%	$12,401–$47,150
22%	$47,151–$100,525
24%	$100,526–$191,950
32%	$191,951–$243,725
35%	$243,726–$626,350
37%	Over $626,350

This is why day traders and short-term investors face a significant tax disadvantage compared to long-term buy-and-hold investors.

Net Investment Income Tax (NIIT)

Higher-income taxpayers face an additional 3.8% Net Investment Income Tax (NIIT) on the lesser of:

Net investment income (capital gains, dividends, interest, rental income), OR
The amount by which your MAGI exceeds the threshold

Filing Status	NIIT Threshold
Single	$200,000
Married Filing Jointly	$250,000
Married Filing Separately	$125,000

Example: Single filer, $250,000 MAGI, $30,000 in long-term capital gains:

Income over threshold: $250,000 − $200,000 = $50,000
NIIT applies to lesser of $30,000 (gains) or $50,000 (overage) = $30,000
NIIT owed: $30,000 × 3.8% = $1,140
Plus 20% long-term capital gains rate on $30,000 = $6,000
Total tax on gains: $7,140 (effective rate: 23.8%)

Capital Gains on Specific Asset Types

Stocks and ETFs

Standard rules apply — short-term or long-term depending on holding period. Dividends are taxed separately (qualified dividends at long-term rates; ordinary dividends at income rates).

Real Estate (Investment Properties)

Long-term gains taxed at 0%/15%/20% like other assets
Section 1250 recapture: Depreciation you previously deducted is “recaptured” at ordinary income rates up to 25% when you sell — this applies even if the overall gain qualifies for long-term rates
1031 exchanges allow deferral of gains if you reinvest in a like-kind property

Cryptocurrency

The IRS treats crypto as property. Every sale, exchange, or use of crypto to purchase goods is a taxable event. Short-term or long-term rules apply based on holding period. See Crypto Taxes 2026.

Collectibles (Art, Coins, Antiques)

Long-term collectible gains are taxed at a maximum rate of 28% — higher than the standard 20% cap for other long-term gains.

Small Business Stock (QSBS)

Qualified Small Business Stock (Section 1202) can exclude up to 100% of gain on the sale of stock in a qualified C-corporation held more than 5 years — one of the most powerful exclusions in the tax code for startup founders and early employees.

Primary Home Sale Exclusion

If you sell your primary residence and meet the ownership and use tests, you can exclude:

$250,000 of gain if single
$500,000 of gain if married filing jointly

Requirements:

You owned the home for at least 2 of the last 5 years
You lived in the home as your primary residence for at least 2 of the last 5 years
You have not used this exclusion within the past 2 years

Example: You and your spouse bought a home for $300,000 and sell it for $750,000 — a $450,000 gain. After the $500,000 exclusion, $0 is taxable.

If your gain exceeds the exclusion limit, the excess is a long-term capital gain subject to normal rates.

Tax-Loss Harvesting

Tax-loss harvesting is the practice of selling investments that have declined in value to generate a capital loss, which then offsets capital gains and reduces your tax bill.

How It Works

You have a $10,000 long-term capital gain from selling Stock A
You also hold Stock B, currently down $6,000 from what you paid
You sell Stock B, generating a $6,000 capital loss
Net taxable gain: $10,000 − $6,000 = $4,000 (instead of $10,000)
Tax saving at 15% rate: $900

The Wash-Sale Rule

You cannot immediately repurchase the same or “substantially identical” security within 30 days before or after selling it for a loss. Doing so creates a “wash sale” — the IRS disallows the loss deduction.

Solution: Buy a different but similar fund during the 30-day window (e.g., sell Vanguard S&P 500 ETF, buy iShares S&P 500 ETF) to maintain market exposure while still realizing the loss.

Capital Loss Carryforward

If your capital losses exceed your capital gains in a given year, you can deduct up to $3,000 of excess losses against ordinary income. Any remaining losses carry forward indefinitely to future tax years.

Strategies to Reduce Capital Gains Tax

1. Hold for the Long Term

The simplest and most powerful strategy — simply wait more than 12 months before selling to qualify for preferential rates.

2. “Gain Harvest” in Low-Income Years

In years when your taxable income falls in the 0% long-term capital gains bracket (under $48,350 single / $96,700 MFJ), intentionally realize long-term gains at zero tax.

3. Invest in Tax-Advantaged Accounts

Capital gains, dividends, and interest inside a Roth IRA or traditional IRA grow tax-free or tax-deferred — no capital gains tax until withdrawal (traditional) or never (Roth).

4. Donate Appreciated Stock to Charity

If you donate stock directly to a charity (rather than selling it first and donating cash), you avoid the capital gains tax entirely AND get a deduction for the full fair market value.

5. 1031 Exchange for Real Estate

When selling investment property, use a 1031 exchange to defer capital gains tax by rolling the proceeds into a similar investment property within 180 days.

6. Qualified Opportunity Zone Investments

Investing capital gains into a Qualified Opportunity Fund (QOF) within 180 days of the sale can defer taxes and potentially eliminate taxes on new gains if held 10+ years.

How to Report Capital Gains

Report capital gains on Schedule D (Capital Gains and Losses) and Form 8949 (Sales and Other Dispositions of Capital Assets).

Your broker will send you Form 1099-B showing proceeds from every sale. Cross-reference this with your own records of purchase price (cost basis) to determine your gain or loss.

Most tax software handles this automatically if you import your 1099-B electronically from your brokerage.

FAQ

Do I have to pay capital gains tax on my investments every year?

Only when you sell. Unrealized gains — appreciation in value while you still hold the asset — are not taxed. This is why long-term buy-and-hold investing is so tax-efficient: you can let gains compound for decades without triggering a tax event.

Are capital gains taxed differently in different states?

Yes. Most states tax capital gains as ordinary income at the state level. California taxes capital gains at the state’s top income rate (up to 13.3%). States with no income tax (Texas, Florida, Nevada, etc.) have no state capital gains tax.

What is the cost basis and why does it matter?

Your cost basis is what you paid for the asset (purchase price + commissions). Capital gain = sale price − cost basis. If you inherited an asset, your cost basis is typically the fair market value at the date of the original owner’s death (stepped-up basis) — potentially eliminating all pre-death appreciation from taxes.

Do capital gains affect my eligibility for SNAP or other government benefits?

Yes — capital gains count as income for most income-tested programs. A large capital gain in one year could temporarily disqualify you from SNAP, Medicaid, or premium tax credits in that year. Plan large asset sales carefully if you’re near income thresholds.
