What it means
When you sell an asset for more than you paid, the difference is a capital gain. Tax authorities split gains by how long you held the asset.
A short-term gain comes from a quick sale, while a long-term gain comes from an asset held for longer than the qualifying period. In the United States, a short-term gain is normally taxed as ordinary income, which means it is added to your salary and taxed at your usual marginal rate.
Long-term gains are taxed at lower rates that are set by the tax authority and can change. Other countries may have no distinction, a different holding period, or an exemption for small gains.
This difference shapes behaviour. An investor who is a few weeks short of the qualifying period may delay a sale to get the lower rate, as long as the price risk of waiting is acceptable.
Active traders accept a higher tax rate because their profits come from frequent trades. For businesses, the treatment depends on the type of entity and the local tax code.
A trading company's profits from selling shares in the course of trade are often treated as ordinary business income rather than as capital gains. Accountants need to know the nature of the asset and the holder's activity before deciding how a gain is reported.
Record keeping is essential. You need the purchase date, the sale date, the purchase price and any costs of buying and selling to work out the gain and its category.
Mistakes in the dates can move a gain from one tax category to the other.
In practice
Real-world examples.
Example
A software engineer buys shares in a start-up fund in March and sells in October after a quick rise. Her profit of $5,000 is a short-term gain and is added to her salary income. She learns that waiting until the following spring would have saved her a meaningful amount of tax.
Example
A small business owner sells a delivery van after 10 months for $3,000 more than its depreciated value. Her accountant treats the gain as part of ordinary business income because the van was used in the business. She records the sale date carefully for the tax return.
Example
A day trader makes 300 trades a year, and every position is held for a few days. All of his profits are short-term gains taxed at his ordinary rate. He sets aside 35% of each month's profit in a separate account to cover his tax bill.
Formula
Calculation
Short-term gain = sale proceeds - purchase cost (including fees), for an asset held for the short-term period or less
Suppose an investor buys 200 shares for $10,000 including fees and sells them nine months later for $14,000 after fees. The short-term gain is 14,000 - 10,000 = $4,000. Assume for illustration an ordinary tax rate of 30%, so the tax is 4,000 x 0.30 = $1,200 and the after-tax profit is $2,800. If the same shares had been held longer than the qualifying period and taxed at an assumed 15%, the tax would be 4,000 x 0.15 = $600, leaving $3,400.Case study
Seen in the real world.
Windmere Growth Club is an illustrative, fictional investment club with 12 members. In November it sold a technology holding bought the previous February, realising a profit of $24,000.
The club's treasurer noticed that the holding period fell a few months short of the one-year mark, so the entire profit would be a short-term gain taxed at ordinary rates. She calculated that, at an assumed 30% short-term rate against an assumed 15% long-term rate, waiting would save about $3,600.
The members debated the risk of waiting, since the share price might drop, and voted to sell half the holding now and half after the one-year date. The illustrative lesson is that tax timing is a trade-off with market risk, and it is best discussed in advance.
Watch out
Common mistakes.
- Assuming every country taxes short-term gains in the same way, when some have no distinction between short and long holding periods.
- Miscounting the holding period, such as counting from the order date rather than the trade date.
- Delaying a sale only to save tax, and then losing more money from a falling price than the tax saving was worth.
Questions
People also ask.
How long must I hold an asset for a long-term gain?
In the United States the holding period must be longer than one year, and other countries set their own periods.
Are short-term gains always taxed more heavily?
In many systems yes, but not everywhere, so check the rules of your own tax authority.
Can losses offset short-term gains?
Generally yes, losses on assets sold in the same period can reduce gains, and the exact order of offsetting depends on local tax rules.
