How This Day Trading Tax Calculator Works
Enter your net trading profit or loss and other income. The calculator shows two scenarios side-by-side: your tax without trader tax status (normal capital gains treatment) and your tax with trader tax status using the Section 475 mark-to-market election.
Without Trader Tax Status
All day trading gains = Short-term capital gains (ordinary tax rates)
Net losses: only $3,000/year deductible against ordinary income
Wash sale rules: apply β cannot deduct losses on wash sale violations
Trading expenses: NOT deductible (personal investment expenses)
Net losses: only $3,000/year deductible against ordinary income
Wash sale rules: apply β cannot deduct losses on wash sale violations
Trading expenses: NOT deductible (personal investment expenses)
With Trader Tax Status + Section 475 MTM
All gains/losses = Ordinary income (same rates, but no capital gains preference)
Loss limit: NONE β full net losses deductible against all income
Wash sale rules: DO NOT apply under MTM election
Trading expenses: Fully deductible as business expenses
SE tax: may apply to trading profits (self-employment income)
Loss limit: NONE β full net losses deductible against all income
Wash sale rules: DO NOT apply under MTM election
Trading expenses: Fully deductible as business expenses
SE tax: may apply to trading profits (self-employment income)
Example
Alex, Single, $50K trading profit, $75K salary, 2026:
Without TTS: $50K short-term CG at ~32% marginal = ~$16,000 tax on trading
With TTS + MTM: $50K ordinary income + $75K salary = $125K total
Tax on additional $50K β $16,000 + SE tax if applicable
Note: TTS primarily benefits those with significant trading LOSSES (no $3K cap) or large deductible expenses
Without TTS: $50K short-term CG at ~32% marginal = ~$16,000 tax on trading
With TTS + MTM: $50K ordinary income + $75K salary = $125K total
Tax on additional $50K β $16,000 + SE tax if applicable
Note: TTS primarily benefits those with significant trading LOSSES (no $3K cap) or large deductible expenses

Trader Tax Status Qualification Checklist
Assess whether your trading activity qualifies for IRS trader tax status
Answer these questions to assess whether your trading activity likely qualifies for IRS trader tax status. This is not legal or tax advice β consult a tax professional.
Important: The IRS evaluates TTS on facts and circumstances. No bright-line rule exists. Tax courts have generally required 720+ trades/year, near-daily trading activity, and substantial investment in time. Merely holding investments without high-frequency activity does not qualify. Always consult a tax professional (especially one specializing in trader taxation) before making a Section 475 election.
Frequently Asked Questions
How is day trading income taxed?
Without trader tax status, all day trading profits are short-term capital gains (held less than 1 year), taxed at your ordinary income tax rate β up to 37%. Losses can offset gains, but net losses are limited to a $3,000 deduction against ordinary income per year. Excess losses carry forward to future years.
What is trader tax status and how do I qualify?
Trader tax status (TTS) is an IRS designation for those trading as a business, not a hobby. To qualify, you generally need: (1) trading is your primary income source, (2) you trade most business days, (3) you hold positions for short periods (typically minutes to days), (4) trades are substantial in number and frequency (IRS generally looks for 720+ trades/year), and (5) you trade for your own account, not clients. TTS allows you to deduct trading expenses (home office, software, equipment, education).
What is the Section 475 mark-to-market election?
Section 475 mark-to-market (MTM) is an optional election available only to traders with trader tax status. Under MTM, you treat all open positions as if sold at year-end fair market value. All gains and losses are treated as ordinary income/loss (not capital gains). Benefits: no $3,000 loss cap, no wash sale rules. Drawbacks: gains taxed at ordinary rates (not the lower 0%/15%/20% LTCG rates) and self-employment tax may apply. Must elect by April 15 of the tax year.
What are wash sale rules for day traders?
Wash sale rules disallow a loss deduction if you buy a substantially identical security within 30 days before or after selling at a loss. Without trader tax status or MTM election, wash sales apply to day traders. With the Section 475 MTM election, wash sale rules no longer apply β all trades are marked to market at year end as ordinary income/loss, eliminating the wash sale issue entirely.
Are day trading profits subject to self-employment tax?
Without trader tax status: no self-employment tax (capital gains are not self-employment income). With trader tax status but without MTM: still no SE tax on capital gains. With trader tax status AND Section 475 MTM election: gains become ordinary income β and depending on structure, may be subject to self-employment tax (15.3% on net earnings). Many active traders use an S-corp structure to mitigate SE tax with TTS + MTM.
