The holding period of your investments is one of the few tax factors entirely under your control. Holding an investment for more than one year transforms its tax treatment from ordinary income rates to preferential long-term rates — potentially saving thousands on a single sale. This guide explains the difference, the threshold, and the strategies to qualify for long-term treatment.
The One-Year Threshold
The IRS divides capital gains into two categories based on how long you held the investment:
Short-term: Held for one year or less. Taxed at your ordinary income tax rate (10%–37%), the same rate as your salary.
Long-term: Held for more than one year. Taxed at preferential rates of 0%, 15%, or 20% depending on your taxable income.
The threshold is the one-year anniversary of the day after your purchase. If you buy on January 1, 2024, your one-year mark is January 2, 2025 (the day after January 1, 2025). Selling on January 1, 2025 is short-term; selling on January 2, 2025 is long-term.
That one day can change your tax rate by 7–20 percentage points.
The Tax Rate Difference
| Taxable Income (Single) | Short-Term Rate (Ordinary) | Long-Term Rate | Difference |
|---|---|---|---|
| $0 – $11,600 | 10% | 0% | 10% |
| $11,601 – $47,025 | 12% | 0% | 12% |
| $47,026 – $100,525 | 22% | 15% | 7% |
| $100,526 – $191,950 | 24% | 15% | 9% |
| $191,951 – $243,725 | 32% | 15% | 17% |
| $243,726 – $518,900 | 35% | 15% | 20% |
| Over $518,900 | 37% | 20% | 17% |
For a worker in the 22% bracket with a $10,000 gain:
- Short-term: $10,000 × 22% = $2,200 tax
- Long-term: $10,000 × 15% = $1,500 tax
- Savings from holding past one year: $700 (32% less tax)
For a high earner in the 35% bracket with a $50,000 gain:
- Short-term: $50,000 × 35% = $17,500 tax
- Long-term: $50,000 × 15% = $7,500 tax
- Savings: $10,000
The savings grow with both income and gain size. For large gains, the holding period decision is worth thousands.

How to Calculate the Holding Period
The IRS counts the holding period from the day after purchase to the sale date:
Purchase date: January 1, 2024 One-year mark: January 2, 2025 (the day after January 1, 2025)
- Sell on January 1, 2025 → short-term (held exactly 365 days, but not more than one year)
- Sell on January 2, 2025 → long-term (held 366 days, more than one year)
For mutual funds and ETFs, the holding period is based on the specific purchase date (each lot has its own holding period). If you bought shares in multiple transactions, each lot has its own one-year anniversary.
Use the "specific identification" method when selling to choose which lots to sell — this lets you sell long-term lots first to minimize taxes.
Strategies to Qualify for Long-Term Treatment
1. Hold Past the One-Year Mark
The simplest strategy: if you have a gain and are within a few weeks of the one-year mark, wait. The tax savings from long-term treatment usually outweigh a few weeks of market risk.
Exception: If you believe the investment is about to decline significantly, selling now (at short-term rates) may be better than watching the gain disappear. But for broad index funds, holding past one year is almost always optimal.
2. Specific Share Identification
When selling, you can choose which shares (lots) to sell. If you have some lots held over one year and some held under, sell the long-term lots first to qualify for the lower rate. Most brokerages support this — you must specify before the sale, not after.
Methods for choosing which shares to sell:
- Specific identification: You pick the exact lots (best for tax optimization)
- First-in, first-out (FIFO): Oldest shares sell first (often results in long-term treatment)
- Average cost: Blends all lots (common for mutual funds, less optimal)
3. Avoid Frequent Trading in Taxable Accounts
Every sale of a held-under-one-year investment creates a short-term gain taxed at ordinary rates. Buy-and-hold investing in taxable accounts naturally qualifies for long-term rates. See Index Fund Investing for the buy-and-hold approach.
4. Use Tax-Advantaged Accounts for Active Strategies
If you trade frequently or hold positions for under a year, do it inside a tax-advantaged account (IRA, 401(k)) where capital gains tax does not apply. Reserve taxable accounts for long-term holdings. This is part of asset location strategy.
When Short-Term Treatment Is Unavoidable
Some situations force short-term treatment regardless of strategy:
Rebalanced positions: If you rebalance your portfolio and sell positions held under one year, those gains are short-term. To avoid this, rebalance by directing new contributions to underweight assets rather than selling.
Mandatory sales: If you need to sell for an emergency or a required distribution, the holding period is what it is.
Vested restricted stock units (RSUs): RSUs are taxed as ordinary income at vesting, regardless of how long you hold them after. The holding period for capital gains starts at vesting, not grant.
The Net Investment Income Tax (NIIT)
High earners face an additional 3.8% tax on investment income (including capital gains) called the Net Investment Income Tax. It applies to taxpayers with modified AGI above $200,000 (single) or $250,000 (married). This tax applies to both short-term and long-term gains, adding to the rates above.
For these earners, the effective long-term rate is 18.8% or 23.8% rather than 15% or 20%.
State Capital Gains Taxes
Most states tax capital gains as ordinary income (no preferential long-term rate), adding to your federal tax. A few states (like California) tax capital gains at the full ordinary state rate, which can be significant. States with no income tax (Texas, Florida, Nevada, etc.) do not tax capital gains at the state level.
Frequently Asked Questions
Q: What if I sell part of a position I bought in multiple transactions? Each purchase (lot) has its own holding period. Use specific identification to sell the lots that qualify for long-term treatment first. Your brokerage can help you select specific lots when selling.
Q: Does reinvesting dividends reset the holding period? No — each reinvestment creates a new lot with its own holding period. The original shares keep their original purchase date. When you sell, you may have a mix of long-term and short-term lots depending on when dividends were reinvested.
Q: Can I sell at a loss to offset short-term gains? Yes. Capital losses offset capital gains of the same type first (short-term losses offset short-term gains), then offset the other type. Short-term losses are valuable because they offset short-term gains (taxed at higher ordinary rates). See Capital Gains Tax Basics for tax-loss harvesting.
Q: Do ETFs and mutual funds distribute capital gains? Yes — when fund managers sell securities inside the fund at a profit, they distribute those gains to shareholders. These are taxable to you even if you did not sell your shares. ETFs are generally more tax-efficient than mutual funds because of their structure. See ETFs Explained.
Q: Is it ever better to sell short-term? Rarely. If the investment is about to decline significantly, locking in a short-term gain may be better than watching it evaporate. But for broad index funds held in taxable accounts, waiting for long-term treatment is almost always optimal.
Q: How do I track holding periods across many investments? Your brokerage tracks this automatically. Each lot in your account has a purchase date. When you sell, your brokerage reports the holding period on your 1099-B form at tax time. You can also view lot details in your brokerage account before selling.
