Experienced commodity futures and options traders know that the market doesn't give profits away—and neither should you to the IRS. Tax mistakes are one of the fastest ways to erode your trading edge, yet many professional traders overlook them. This checklist, inspired by the hard-hitting case studies in Futures Under Fire, will help you identify and avoid the three most common tax pitfalls that cost serious money. After completing this checklist, you'll have a clear action plan to legally minimize your tax burden, leverage Section 1256 mark-to-market accounting, and explore private structures that protect your capital. Use it before you file your next return or at the start of a new trading year.
Before You Start: What You Need
- Your previous year's trading records (P&L statements, trade confirmations, broker statements).
- A basic understanding of IRS tax treatment for Section 1256 contracts (futures and options on futures).
- Access to a qualified tax professional who specializes in trader taxation.
- A copy of Futures Under Fire for deeper case studies—grab it on Amazon here.
- At least 30 minutes to review each item carefully.
Mistake #1: Ignoring Section 1256 Mark-to-Market Rules
Action: Verify that you elected (or should elect) mark-to-market accounting for your futures and options trades.
Why it matters: Section 1256 of the Internal Revenue Code allows you to treat 60% of your gains as long-term capital gains and 40% as short-term, regardless of holding period. This 60/40 split is a huge tax advantage compared to the ordinary income rates that apply to securities traders. But many traders fail to make the election or use it incorrectly. Without it, you're leaving tax savings on the table—and potentially paying up to 37% on gains that could be taxed at 20% (for long-term).
How to verify: Check your previous year's IRS Form 6781. If you filed it, you're using mark-to-market. If not, you need to file Form 3115 (Change in Accounting Method) to elect mark-to-market for the current year. This election must be made by the due date of the return (including extensions). See Futures Under Fire for a detailed walkthrough of the election process and common pitfalls.
Mistake #2: Misclassifying Gains and Wash Sales on Futures
Action: Confirm that you are applying wash-sale rules correctly—or that you have opted out of them via mark-to-market.
Why it matters: Many traders mistakenly apply the securities wash-sale rule (30-day window) to futures, but futures are not subject to wash-sale rules under Section 1091. However, if you elect mark-to-market, you avoid wash-sale issues entirely. If you don't elect, you might be overstating your losses or missing out on legitimate deductions. The result? You could be paying more tax than necessary on gains that should be offset by losses.
How to verify: Review your broker's statements for any wash-sale adjustments. If you see them, check whether they are correctly applied to futures. If you're using mark-to-market, wash-sale rules do not apply—so you can ignore those adjustments. If you're not using mark-to-market, you need to adjust your cost basis manually. Futures Under Fire includes real-world examples of traders who lost thousands due to misclassification.
Mistake #3: Failing to Elect Mark-to-Market Accounting (Form 3115)
Action: Ensure you have filed Form 3115 in the correct year and with the correct method.
Why it matters: The mark-to-market election is irrevocable (unless you get IRS permission). Many traders file Form 3115 incorrectly or miss the deadline, locking themselves into a suboptimal tax treatment for years. The election allows you to mark all open positions to market at year-end, so you pay tax on unrealized gains—but you can also deduct unrealized losses. This is a powerful tool for capital preservation strategies and trader performance optimization.
How to verify: Check your tax return for Form 3115. If you didn't file it, you can still elect for the current year by filing with your return. The form requires a statement of the change in accounting method and a description of your trading business. Use institutional-grade trading knowledge to ensure you meet the 'trader in securities' definition (substantial, frequent, and regular trading). Futures Under Fire provides a step-by-step guide to filing Form 3115 correctly.
Strategic Tax Elections and Private Structures
Action: Consider forming a legal entity (LLC, S-Corp, or Family Limited Partnership) to shield trading income.
Why it matters: Private structures can help you separate personal and trading assets, reduce self-employment tax (if structured correctly), and provide liability protection. For example, a Family Limited Partnership allows you to distribute income to family members in lower tax brackets, while an LLC can enable you to deduct business expenses (trading education, software, data subscriptions) more aggressively. These are advanced professional trader insights that go beyond basic tax planning.
How to verify: Consult with a tax attorney or CPA who specializes in trader entities. Review your state's requirements for LLC or partnership formation. Ensure you have a written business plan and operate the entity as a real business (separate bank account, trading account, business address). Futures Under Fire includes a chapter on using private structures to keep more of your profits.
Action: Track all business expenses meticulously.
Why it matters: As a professional trader, you can deduct expenses like terminal fees, data subscriptions (e.g., CME Group's market data), educational materials (including this book), and home office expenses. These deductions lower your taxable income and increase your net returns. Many traders overlook small but cumulative costs.
How to verify: Use expense tracking software or a spreadsheet. Categorize expenses by type (education, software, office, travel). Keep receipts for any expense over $75. Claiming these correctly is part of elite market analysis for traders applied to your own finances.
