Tax Rules for Day Traders: Trader Status and the Section 475 Election

How are day traders taxed?
- Most active traders are investors for tax purposes; trader status requires meeting IRS criteria.
- Qualifying traders deduct business expenses on Schedule C, and their gains stay capital unless they elect Section 475.
- Trading gains aren't subject to self-employment tax, even for qualifying traders.
- Short-term gains are taxed at ordinary rates in either case.
What qualifies you as a trader?
- You must seek profit from daily price movements, not from dividends, interest, or long-term appreciation.
- Activity must be substantial and carried on with continuity and regularity.
- The IRS weighs holding periods, trade frequency and dollar volume, reliance on trading income, and time devoted.
- There is no statutory trade count, and calling yourself a trader doesn't establish the status.
What does the Section 475 election do?
- Securities in the trading business are marked to market at year-end, as if sold at fair market value.
- Gains and losses become ordinary and go on Form 4797, so the $3,000 capital loss limit no longer applies.
- The wash-sale rule doesn't apply to securities covered by the election.
- Covered gains lose access to long-term capital gains rates, so the election cuts both ways.
When must the Section 475 election be made?
- Individuals must make it by the original due date, not including extensions, of the return for the year before it takes effect.
- For example, an election for 2027 is generally due by April 15, 2027, with the 2026 return or an extension request.
- Form 3115 is then filed for the year the election takes effect.
- Investment positions must be clearly identified and held separately to stay outside the election.
What expenses can traders deduct?
- Qualifying traders deduct ordinary and necessary business expenses such as data, software, equipment, and a qualifying home office.
- Investors can't deduct investment expenses, and the July 2025 tax law made that disallowance permanent.
- Investment interest remains deductible for itemizers, up to net investment income.
- Trading in securities is a specified service under Section 199A, which limits the qualified business income deduction at higher incomes.
How do wash sales and estimated taxes work for traders?
- Without a 475 election, the wash-sale rule disallows losses on repurchases within 30 days, including across your accounts.
- A repurchase inside an IRA can make the loss permanently unusable.
- Penalties are generally avoided by paying 100% of last year's tax, 110% if prior-year AGI exceeded $150,000, or 90% of this year's.
- The annualized income method can lower early payments when gains come late in the year.
Key takeaways
- Trader status turns on the nature and regularity of trading, not self-description.
- A Section 475 election makes gains ordinary and removes the $3,000 loss limit and wash-sale rule.
- The election deadline is the prior year's original return due date, without extensions.
- Confirm status, elections, and estimates with a CPA experienced with traders.
