Full-time day trading tax questions - Are expenses deductible and do I pay self-employment tax?

So if I understand right, if I don't do the MTM election, I basically can't deduct any of my trading expenses? But if I do the MTM election, I can deduct them but won't have to pay self employment tax on my trading profits? Is that right?

Your first point is mostly correct - without MTM election, your trading expenses would be considered investment expenses, which currently aren't deductible for most taxpayers under the Tax Cuts and Jobs Act (at least until 2026). With MTM election, you gain the ability to deduct your ordinary and necessary business expenses on Schedule C. And you're also correct that your actual trading profits (capital gains) wouldn't be subject to self-employment tax, even when you have trader tax status with MTM. Only other business income unrelated to your actual trading activity might trigger SE tax.

How exactly does taxr.ai determine if you qualify for trader status? I'm trading about 3-4 hours daily but still have a part-time job. Would that work or do I need to be 100% full time?

Sounds interesting but how reliable is the info? Tax advice from AI seems risky when the IRS could come after you. Did you verify with a real accountant after?

The platform uses the same criteria the IRS looks at: trading frequency, holding periods, time dedicated to trading, and whether you depend on trading income. For your situation with 3-4 hours daily plus a part-time job, it would analyze your specific pattern and compare it to tax court precedents to determine if you meet the substantial, regular, continuous activity test. Completely understand the concern about AI tax advice. That's exactly why I liked taxr.ai - it doesn't just give generic answers but shows you the relevant tax code sections and court cases its advice is based on. I did have my accountant review it, and he was impressed with the accuracy. He implemented the same approach the AI recommended, but understood my situation much faster after seeing the analysis.

How does this actually work? Does it just call the IRS for you or something? Seems weird that there's a service just to get through to a government agency.

Yeah right... I've tried everything to reach the IRS and wait times are HOURS. No way this actually works. Sounds like a scam to me.

It uses an automated system that navigates the IRS phone tree and waits on hold for you. When an agent finally answers, you get a call connecting you directly to them. It basically handles the painful waiting process so you don't have to sit there listening to the hold music for hours. I felt exactly the same way before trying it! I was beyond skeptical after wasting entire afternoons on hold. What convinced me was that they don't charge if they can't get you through. When I actually got connected to an IRS agent after trying unsuccessfully for days on my own, I was genuinely surprised. The agent I spoke with answered all my specific questions about expense documentation requirements for trader status.

Thanks for bringing this up. I've heard about MTM but wasn't sure about the benefits vs drawbacks. Does going MTM mean I lose the preferential tax rates on long-term capital gains? That seems like a big disadvantage if I occasionally hold positions longer.

Yes, that's exactly right - with MTM, all your trading gains and losses are treated as ordinary income, regardless of holding period. You lose the preferential tax rates on long-term capital gains (which can be significant if you're in a higher tax bracket). MTM works best for high-frequency traders who rarely hold positions overnight or for more than a few days. If you occasionally take longer-term positions, you might want to consider maintaining two separate accounts - one for your day trading (MTM) and another for your investment positions (non-MTM). This gives you the best of both worlds, but it adds some complexity to your recordkeeping.

I think you're confusing some terms. Individual traders don't need to register as securities dealers or collect sales tax. Dealers are market makers who profit from the spread, not individual traders. There's no sales tax on securities transactions (though there are SEC fees).

You're right, I mixed up some terminology there. Thanks for the correction! I was thinking about the distinction between traders and dealers for tax purposes, not sales tax. Dealers must report gains/losses as ordinary income and mark positions to market, while traders have the option to elect MTM treatment.

This is incredibly helpful, thank you! I'm particularly interested in the documentation aspect you mentioned. When you say "daily trading logs" - what specific information should I be tracking? Is it just the trades themselves, or do I need to document the time spent researching, analyzing charts, etc.? And how detailed does the trading strategy documentation need to be for IRS purposes? I'm trying to set up proper systems from day one rather than scrambling to recreate records later. Also, did you find any particular software or tools that made the record-keeping easier for trader tax status qualification?

Great question about documentation! For daily trading logs, you should track: date/time of trades, securities traded, buy/sell prices, quantities, holding periods, and most importantly - time spent on trading activities each day (market analysis, research, trade execution, etc.). The IRS wants to see this is a business activity, not just occasional investing. For trading strategy documentation, keep it detailed but practical. Document your methodology (technical analysis, fundamental research, risk management rules), market sectors you focus on, typical holding periods, and decision-making processes. Think of it as proving this is systematic business activity rather than gambling or casual investing. I use TraderLog for trade tracking combined with a simple Excel sheet for daily time logs. Some people prefer TurboTax Business or FreeTaxUSA for integrated tracking. The key is consistency - whatever system you choose, use it religiously from day one. Also keep all receipts for trading-related expenses (software subscriptions, data feeds, equipment, home office costs) and maintain a separate business bank account if possible. This creates a clear paper trail that supports your trader status claim.

Great questions! For daily trading logs, I track: entry/exit times, number of trades, hours spent on market research, chart analysis time, and brief notes on my trading rationale. The IRS wants to see this is a business-like activity, not just casual investing. For strategy documentation, I keep a written trading plan that outlines my methods, risk management rules, and market approach. Nothing too complex - just enough to show systematic business activity rather than gambling or casual trading. As for software, I use TradingDiary Pro for tracking trades and time spent, plus a simple Excel spreadsheet for daily activity logs. Some traders I know swear by TraderTaxStatus.com for comprehensive record-keeping specifically designed for IRS trader status requirements. The key is consistency - pick a system and stick with it from day one. One tip: also document any trading education you pursue (courses, books, seminars) as these can be legitimate business expenses and show your professional approach to trading.

Great questions! For the daily trading logs, you'll want to track more than just the trades. I document: start/end times of trading sessions, hours spent on market research, chart analysis time, trade execution times, and even time spent reading financial news or educational materials. The IRS wants to see that trading is your primary business activity. For strategy documentation, keep it detailed but not overly complex. Document your criteria for entering/exiting trades, risk management rules, position sizing methods, and market conditions you focus on. I also keep notes on strategy adjustments and why I made them - shows this is serious business activity, not gambling. As for software, I use a combination of tools. TraderSync helps with trade tracking and P&L analysis, and I keep a simple Excel spreadsheet for daily time logs. Some traders use specialized tax software like TradeLog, but honestly a well-organized spreadsheet can work just as well if you're consistent about updating it daily. The key is consistency - start these records from day one and maintain them religiously. It's much easier than trying to reconstruct months of activity later, and it really demonstrates the business-like nature of your trading to the IRS.

Great question about documentation! For daily trading logs, I track: date/time of trades, symbols, entry/exit prices, holding period, and most importantly - the rationale behind each trade (technical analysis, news events, etc.). The IRS wants to see that you're making informed business decisions, not just gambling. For time tracking, I log hours spent on market research, chart analysis, reading financial news, and actual trading. The key is showing this is your primary occupation, not a hobby. I use a simple spreadsheet with columns for date, start/end times, and activities. For strategy documentation, I maintain a written trading plan that outlines: markets I trade, risk management rules, position sizing methodology, and entry/exit criteria. Update it whenever you refine your approach - this shows business evolution. Software-wise, I use TradeLog for trade tracking (imports from most brokers) and RescueTime to automatically track computer usage on trading-related activities. Some traders also use TurboTax Business or FreeTaxUSA for the actual tax prep, but the key is having clean, organized records going in. The documentation serves two purposes: proving trader status qualification and supporting your business expense deductions. The IRS typically looks for patterns over 6-12 months, so start tracking everything from day one!

For daily trading logs, I track: date/time of trades, symbols, entry/exit prices, holding periods, and most importantly - the rationale for each trade (technical analysis, news catalyst, etc.). I also log non-trading business activities like market research time, platform maintenance, and continuing education. For strategy documentation, I keep a written trading plan that outlines my methods, risk management rules, and market approach. The IRS wants to see that you're operating like a business, not just gambling. I update this whenever I refine my strategy. Software-wise, I use TraderLog for trade tracking (it integrates with most brokers) and keep a simple Excel spreadsheet for daily time logs. Some people use more sophisticated tools like TradeZella, but the key is consistency - whatever system you choose, stick with it religiously. The IRS cares more about having complete, contemporaneous records than fancy software. Pro tip: Also document any trading-related meetings, conferences, or networking events. These support the "business purpose" aspect that's crucial for trader status qualification.
