Trader vs investor: what the IRS looks at
Trader tax status is not an election. It is a facts-and-circumstances test. IRS Topic No. 429 says you are a trader if both are true:
- You seek to profit from daily market movements in prices, not from dividends, interest or long-term appreciation.
- Your activity is substantial and carried on with continuity and regularity.
The IRS and the courts weigh typical holding periods, the frequency and dollar amount of trades, how much time you spend, and whether you trade to produce income for a living. Calling yourself a day trader does not decide it. A trader can also hold an investment account. Securities held for investment must be identified in your records on the day you buy them.
Most people who trade often but also hold a full-time job, trade sporadically, or hold positions for weeks are treated as investors. Close cases turn on the facts.
The Section 475(f) mark-to-market election and its deadline
A trader may elect mark-to-market accounting under IRC §475(f). At year end, positions held in the trading business are treated as sold at fair market value. Gains and losses become ordinary, so losses are not held to the capital loss limit and the wash sale rules do not apply to those securities.
Deadline. Under Rev. Proc. 99-17, an existing taxpayer files the election statement by the original due date of the prior year’s return, without extensions. You attach it to that return or to your extension request. For a calendar-year individual electing for 2027, that means by April 15, 2027. The 2026 election window closed on April 15, 2026.
New taxpayers not required to file a return for the prior year, such as a new entity, place the statement in their books and records within 2 months and 15 days after the first day of the election year, then attach it to that year’s return.
What the statement says. That you elect under Section 475(f), the first tax year it applies, and the trade or business it covers. You then file Form 3115 for the year of change. The IRS generally does not accept late elections, so plan before April.
The trade-off. Ordinary treatment also means gains lose long-term capital gain rates, and unrealized gains at year end are taxed. Revoking the election later follows IRS procedures. It is a decision to model, not a default.
Wash sales, Form 4797, Schedule D and expenses
- Trader without the election. Gains and losses go on Form 8949 and Schedule D. The wash sale rules and capital loss limits still apply. Expenses go on Schedule C.
- Trader with the 475(f) election. Gains and losses on business securities go on Form 4797, Part II, as ordinary. Expenses go on Schedule C. Securities you identified as investments stay on Schedule D.
- Commissions and fees are not separate deductions. They are part of figuring gain or loss.
- Self-employment tax. IRS Topic 429 says trading gains and losses are not subject to self-employment tax.
Broker Forms 1099-B are built for investors and often report wash sale adjustments. A trader return usually needs reconciliation between broker reports and the method you actually use.
Entity options: approach with care
You do not need an entity to qualify. Some traders trade through a partnership or an S corporation to pay a salary that supports retirement plan contributions or health insurance. That adds a business return, payroll filings and state fees. In DC, Maryland and Virginia, it can also add state entity filings. It only makes sense when the numbers support it. See LLC vs S corp for the basics.
