For US federal capital-gains purposes, the general holding-period boundary is one year or less for short term, more than one year for long term. “Under one year” leaves out the exactly-one-year case and is not an accurate shortcut.
The distinction applies after you establish that the asset and transaction use capital-gains treatment. Special contracts, elections and account types can follow different rules. IRS Topic 409
Rate Labels Are Not a Complete Tax Calculation
Net short-term capital gains generally use ordinary income rates. Net long-term capital gains may qualify for lower rates, with exceptions and potential additional taxes. The applicable result depends on taxable income, filing status and the year.
Do not use an old table of single-filer thresholds to calculate a different year's return. Nor should you multiply all trading profit by one headline bracket and treat the result as an exact liability. Gains can interact with other income, deductions and losses.
A Worked Holding-Period Check
For an ordinary purchased capital asset, the IRS generally counts from the day after acquisition through the disposition date. Check the actual purchase and sale dates, rather than assuming that twelve monthly statements prove “more than one year.” Special acquisition methods and certain transactions can change the calculation. IRS Publication 550
Keep the lot's acquisition date, adjusted basis and disposal record together. Selling one of several lots can produce a different holding period from selling another.
Futures and Forex Need Their Own Classification
Qualifying Section 1256 contracts generally use a 60% long-term and 40% short-term allocation, with mark-to-market rules, rather than simply following the time held. Use the IRS Form 6781 guidance to identify the reporting framework.
Do not extend that result to every foreign-currency product or a prop reward based on simulated futures. The contract and taxpayer relationship matter. An instrument should not be chosen purely for a tax treatment before its trading risks are understood.
Avoid Letting Tax Timing Dictate an Unsafe Position
A lower potential rate does not compensate for an unlimited market loss. If keeping a position open changes its risk beyond your plan, reassess the investment decision as well as the tax consequence.
Before selling a loss position, check wash-sale implications, including purchases in other accounts. For a trading business, confirm whether a valid Section 475 election affects the position. These are separate checks from the holding period.
Frequently Asked Questions
Is exactly one year long term?
Generally no. Long-term treatment requires more than one year for assets using the ordinary holding-period rule.
Are the highest long-term and ordinary rates everyone's rates?
No. They are not a substitute for a calculation using the applicable tax year, income and filing status.
Does a higher gross return guarantee more after-tax income?
No. Costs, loss treatment and taxes affect the outcome. Compare net results using the same assumptions.
