Should I set up an LLC for day trading? Hearing conflicting advice on tax benefits

I've been day trading for about a year and made around $180K in profits last year. Trading through my personal brokerage account currently.

I keep seeing YouTube videos and Instagram posts saying I should set up an LLC or S-Corp for trading to get better tax treatment. Some say it lets you deduct home office, equipment, education costs, etc.

If it does make sense, should I do LLC or S-Corp? And can I elect trader tax status?

Most of those YouTube videos are BS or selling courses. An LLC doesn't change your tax treatment at all - it's just a legal entity. The tax stuff comes from trader tax status (TTS) which you can elect as an individual without an LLC.

That said, if you qualify for TTS, there are some benefits to using an entity. But most retail traders don't actually qualify.

CPA specializing in trader taxation here. Let's clear up the confusion:

LLC vs. No LLC: By default, a single-member LLC is a "disregarded entity" for tax purposes. It doesn't change anything tax-wise - you still report on Schedule D like normal. An LLC primarily provides liability protection, which isn't super relevant for trading.

Trader Tax Status (TTS): This is the key thing. If you qualify (more on this below), you can deduct trading expenses as ordinary business expenses and potentially elect mark-to-market accounting.

To qualify for TTS, you need:

• Substantial trading activity (generally 4+ trades per day, nearly every market day)
• Average holding period of 31 days or less
• Trading is your primary income source
• You spend substantial time on trading (4+ hours per day)

If you don't meet ALL of these, you're an investor, not a trader, and TTS doesn't apply.

I definitely meet those criteria. I trade SPY options and futures, usually 15-20 trades per day, rarely hold overnight. This is my full-time job.

So if I qualify for TTS, what's the benefit of doing it through an entity vs. just electing TTS as an individual?

Okay, sounds like you likely qualify. Here's the comparison:

Individual TTS (Schedule C):

• Can deduct trading expenses on Schedule C
• Can elect mark-to-market (MTM) accounting
• But: Subject to 15.3% self-employment tax on net trading income if you're not careful with elections
• Simpler to administer

Entity TTS (LLC taxed as S-Corp):

• Same deductions and MTM election
• Trading income is NOT subject to self-employment tax (this is the big win)
• More complexity: need separate books, payroll if you pay yourself a salary, corporate tax return
• Cost: $2K-5K per year in accounting fees

At $180K profit, avoiding 15.3% self-employment tax could save you ~$27K. So an S-Corp might make sense, but you need to factor in the compliance costs.

Tax attorney here. I want to clarify Robert's point about self-employment tax because this is a common misconception.

Trading gains are generally NOT subject to self-employment tax, even on Schedule C. The confusion comes from the fact that you report on Schedule C, but trading income is considered "passive" not "active business" income for SE tax purposes.

So the self-employment tax savings Robert mentioned usually don't apply. The main benefits of TTS are:

1. Deducting trading expenses (home office, data feeds, computers, education) as ordinary business expenses rather than misc. itemized deductions
2. Mark-to-market election to avoid wash sale rules and capital loss limitations

For most traders, an LLC/S-Corp doesn't add much value over individual TTS unless you have other business activities.

Jennifer is correct on the SE tax issue - I oversimplified. Trading income itself is generally not subject to SE tax.

The S-Corp structure can still make sense if you're providing trading services (like managing money for others) or have trading-related business income beyond just your own trading. But for pure proprietary trading, you're right that individual TTS is usually sufficient.

This is super helpful, thanks. So it sounds like for my situation (just trading my own money), I should:

1. File TTS as an individual on Schedule C
2. Elect mark-to-market by filing Form 3115
3. Deduct my trading expenses (home office, TradingView subscription, etc.)
4. Skip the LLC/S-Corp complexity

Is that the right takeaway?

Yes, that's teh right approach for most full-time traders. A few additional points:

• The MTM election needs to be made by April 15 of the year you want it to take effect (or by the extended deadline if you file an extension)
• MTM is a permanent election - you can't easily reverse it
• Keep detailed records of your trading activity to substantiate TTS if you get audited
• Work with a CPA who understands trader taxation - this is a specialized area

Don't rely on YouTube influencers or generic tax advice. Get professional help.

One thing to add: if you're trading futures or Section 1256 contracts (like SPY options you mentioned), those already get favorable tax treatment - 60% long-term / 40% short-term regardless of holding period.

MTM election can sometimes make this WORSE if you're profitable, because you convert 60% long-term gains (taxed at 20% max) to ordinary income (taxed up to 37%).

So for futures/1256 traders, MTM might not make sense unless you have lots of losses to deduct imo.

I mean wow, okay that's a good point about Section 1256. I trade SPY options which I think qualify for 60/40 treatment haha.

Sounds like I need to sit down with a specialist CPA and run the numbers. The deductions alone might be worth it even without MTM.

Thanks everyone for talking me out of the LLC rabbit hole. Glad I asked here before dropping $2K on some "trading entity setup" course.

Quick question for anyone still following this thread - does Trader Tax Status work the same way for crypto traders as it does for stock/options traders?

I trade Bitcoin and ETH full-time, 20-30 trades per day, definitely meet the volume requirements. But I've heard the IRS treats crypto as property not securities, so I'm not sure if TTS applies.

Anyone have experience with this? My accountant seems confused about it too.

Anyone have experience with the Section 475(f) mark-to-market election for day traders? My CPA says if I qualify as a 'trader in securities' (not just an investor), I can deduct trading losses as ordinary losses without the $3K capital loss limitation. The trade-off is that I'd recognize all unrealized gains/losses at year-end. For someone who closes all positions daily, the unrealized gains issue is minimal.

@Joe_from_TX_3 — The 475(f) election is powerful but the 'trader in securities' threshold is high. The IRS looks at: (1) frequency and regularity of trading, (2) whether trading is your primary income source, (3) whether you spend substantial time trading, (4) continuity — sporadic trading doesn't qualify. If you qualify, the benefits are significant: ordinary loss treatment, no wash sale rule application, and trading expenses are fully deductible against trading income on Schedule C. The election must be filed by the due date of the prior year's return — it's irrevocable for that year. Consult a tax attorney before making the election; getting it wrong can create unexpected tax liabilities.
