Tax Optimization: Keep 20-40% More of What You Earn
You made $100,000 trading this year. Congratulations!
Now send $22,000-$37,000 to the IRS. Oh, and state taxes too.
What you keep: $57,000-$68,000.
🚨 Real Talk
Most traders focus on making money. Smart traders focus on keeping money.
Tax optimization isn't sexy. But it's 20-40% of your returns. Ignore it at your peril.
In this lesson, you'll learn:
- Short-term vs. long-term gains (hold 366 days, save 17%)
- Trader Tax Status (TTS): Deduct business expenses legally
- Wash sale rule (and how to avoid it)
- Entity structuring (S-Corp saves $18K/year on $200K profit)
⚡ Quick Wins for Tomorrow (Click to expand)
- Check positions approaching 366 days — Any position held 365 days? Hold one more day for long-term rates (15% vs 37%). Could save 22% on that gain.
- Harvest losses before year-end — Losing positions? Sell before Dec 31 to offset gains. Wait 31 days to avoid wash sale rule if re-entering.
- Count your trades for TTS eligibility — Need 720+ trades/year (4/day avg) for Trader Tax Status. If close, increase frequency to unlock business deductions.
Short-Term vs. Long-Term Capital Gains
The IRS treats holding periods VERY differently.
Hold Less Than 1 Year
Tax rate: Ordinary income (22-37%)
$100K gain, held 364 days:
Tax: $22K-$37K (depending on bracket)
Net: $63K-$78KShort-term = brutal tax hit. Most day traders pay this.
Hold More Than 1 Year
Tax rate: Long-term capital gains (0-20%)
$100K gain, held 366 days:
Tax: $0-$20K (depending on income)
Net: $80K-$100K
Savings vs. short-term: $17K+Two extra days of holding = $17K saved. Do the math.
💡 The Aha Moment
364 days vs. 366 days = 17% tax savings on $100K gain.
If you're swing trading anyway, consider holding winners past 1 year.
Qualify as a "Professional Trader" (Legally)
If you trade frequently enough, you can qualify for Trader Tax Status. Benefits are massive.
What Is TTS?
IRS criteria (all must be met):
- Substantial activity: 750+ trades/year (guideline)
- Regularity: Trade most days market is open
- Continuity: Trading is primary income source
- Intent: Profit from short-term price movements
If you qualify: Deduct business expenses (software, data, home office, etc.)
TTS Benefits
Business Expense Deductions:
- Trading platform: $200/mo × 12 = $2,400
- Market data: $2,000/month = $24,000
- Home office: $500/month = $6,000
- Computer equipment: $5,000
- Education (courses, books): $3,000
Total deductions: $40K+/year
Tax savings: $40K × 32% = $12,800TTS = $12K+ saved annually. Worth pursuing if you qualify.
You Sold at a Loss. But You Can't Deduct It.
This is where traders get burned.
Example:
Jan 1: Buy 100 SPY at $500 = $50,000
Jan 15: Sell 100 SPY at $480 = $48,000 (loss: -$2,000)
Jan 20: Buy 100 SPY at $485 (within 30 days)
Result: Loss DISALLOWED (wash sale rule)
Instead: -$2K added to cost basis of new positionYou can't deduct the loss because you repurchased within 30 days.
3 Ways to Avoid
- Wait 31 days: sell at loss, wait 31 days, rebuy
- Buy similar (not identical) security: Sell SPY, buy IVV or VOO (both track S&P 500, not "substantially identical" per IRS)
- Use Mark-to-Market accounting: Eliminates wash sale rule entirely
MTM Election (Day Traders)
What it does: Treats all positions as "sold" on Dec 31 (paper gains/losses count)
Benefit: Eliminates wash sale rule
Downside: Lose long-term capital gains treatment
Good for day traders. Bad for position traders.
S-Corp vs. LLC: The $18K/Year Difference
If you're making $200K+ trading, entity structure matters. A lot.
Individual (Schedule D)
$200K profit:
Income tax: $200K × 32% = $64,000
Simple, but highest tax.LLC (Pass-Through)
$200K profit:
Income tax: $200K × 32% = $64,000
SE tax: $200K × 15.3% = $30,600
Total: $94,600
Ouch! Self-employment tax kills you.S-Corp (The Winner)
$200K profit split:
Salary: $80K (subject to SE tax)
Distribution: $120K (NO SE tax!)
SE tax: $80K × 15.3% = $12,240
Income tax: $200K × 32% = $64,000
Total: $76,240
Savings vs. LLC: $94,600 - $76,240 = $18,360/year!S-Corp = $18K saved annually at $200K profit. Worth the admin overhead.
🎯 When to Consider S-Corp
Threshold: $75K+ net profit from trading
Below that? Admin costs outweigh tax savings.
Above that? S-Corp likely pays for itself.

Turning Losers Into Winners
December strategy: Realize losses to offset gains.
Year-end positions:
- SPY: +$50,000 gain (sell, lock gain)
- QQQ: -$15,000 unrealized loss (sell, realize loss)
- IWM: +$5,000 gain (sell)
Net taxable gain: $50K + $5K - $15K = $40K
Tax saved: $15K loss × 37% rate = $5,550
Action: After 31 days, rebuy QQQ (maintain exposure)🎓 Key Takeaways
- Hold > 1 year for long-term gains (0-20% vs. 22-37%)
- Trader Tax Status: Deduct business expenses (save $10K+/year)
- Avoid wash sales: Wait 31 days or buy similar security
- S-Corp saves $18K/year on $200K profit vs. LLC
- Tax-loss harvest in December: Offset gains with losses
