Tax-Loss Harvesting: Turn Market Losses Into Tax Savings

Market down? There's a silver lining: tax-loss harvesting can turn paper losses into real tax savings.

What Is Tax-Loss Harvesting?

Selling investments at a loss to offset capital gains and reduce your tax bill.

The Benefits:

• Offset capital gains dollar-for-dollar
• Offset up to $3,000 of ordinary income
• Carry forward unused losses indefinitely
• Lower your current year tax bill

How It Works

Example:

Portfolio Activity:

• Stock A: Sold for $10,000 gain
• Stock B: Currently down $10,000

Action:

• Sell Stock B to realize the $10,000 loss
• Losses offset the gains = $0 taxable gain
• Tax saved: $1,500 (15% capital gains rate)

Then:

• Reinvest proceeds in similar (but not identical) investment
• Maintain market exposure
• Capture the tax benefit

The Rules

Wash Sale Rule (Important!)

Can't buy "substantially identical" security 30 days before or after the sale.

Violation Example ❌:

• Sell Vanguard S&P 500 ETF (VOO)
• Immediately buy Vanguard S&P 500 ETF (VOO)
• Loss is disallowed!

Compliant Example ✅:

• Sell Vanguard S&P 500 ETF (VOO)
• Buy Schwab S&P 500 ETF (SCHX)
• Different fund, but tracks same index
• Loss is allowed!

Capital Loss Hierarchy:

1. First offset same type: short-term losses offset short-term gains
2. Then offset opposite type: remaining losses offset other gains
3. Finally offset income: up to $3,000 per year
4. Carry forward: unused losses to future years

Tax Rates (2026)

Short-Term Capital Gains (held <1 year):

Taxed as ordinary income:

• 10%, 12%, 22%, 24%, 32%, 35%, 37%

Long-Term Capital Gains (held >1 year):

Preferential rates:

• 0%: Income under $47,025 (single) / $94,050 (married)
• 15%: Income $47,025-$518,900 (single)
• 20%: Income over $518,900 (single)

Priority: Offset short-term gains first (higher tax rate)

Practical Strategies

1. End-of-Year Review

• Review portfolio in November/December
• Identify positions with losses
• Calculate potential tax savings
• Execute harvesting before Dec 31

2. Replace with Similar Assets

3. Use ETF Pairs

Keep two similar ETFs:

• Alternate selling between them
• Always stay invested
• Harvest losses throughout the year

4. Don't Wait Until Year-End

• Harvest losses anytime you have gains
• Don't wait for December (prices might recover)
• Especially important in volatile markets

Real Example: $100,000 Portfolio

Scenario:

• Sold Stock A: $20,000 gain
• Stock B down 15% (-$5,000 unrealized loss)
• Stock C down 10% (-$3,000 unrealized loss)
• In 24% tax bracket

Without Tax-Loss Harvesting:

• Taxable gain: $20,000
• Capital gains tax: $3,000 (15% rate)

With Tax-Loss Harvesting:

• Sell Stock B and C
• Total losses: $8,000
• Net gain: $20,000 - $8,000 = $12,000
• Capital gains tax: $1,800
• Tax saved: $1,200

Plus: $4,000 carries forward to next year

Additional Benefit:

• Reinvested $8,000 in similar ETFs
• Maintained market exposure
• Same diversification
• Lower cost basis for future growth

When It Makes Sense

Do Tax-Loss Harvest If:

• You have taxable investment accounts
• You have capital gains this year
• You're in 22%+ tax bracket
• You have significant unrealized losses
• You can reinvest in similar funds

Skip It If:

• All money in 401(k)/IRA (already tax-advantaged)
• You're in 0% capital gains bracket
• Losses are very small (<$500)
• You can't find suitable replacement

Automated Tax-Loss Harvesting

Many robo-advisors offer automatic harvesting:

• Wealthfront: Free with account
• Betterment: Free with account
• Schwab Intelligent Portfolios: Free
• Vanguard Digital Advisor: 0.15% fee

Benefits:

• Monitors daily
• Automatically harvests
• Reinvests immediately
• Tracks wash sales

Drawbacks:

• Management fees
• Less control
• May create lot complexity

Common Mistakes to Avoid

1. Violating wash sale rule - Wait 31 days
2. Selling for tiny losses - Transaction costs matter
3. Forgetting about dividends - Reinvested dividends create new lots
4. Not tracking basis - Keep good records
5. Ignoring state taxes - Some states have different rules

Advanced Strategy: Direct Indexing

For portfolios $100,000+:

• Own individual stocks instead of ETFs
• Harvest losses on specific stocks
• Maintain index exposure
• Potential for significant tax alpha

The Bottom Line

Tax-loss harvesting is one of the few "free lunches" in investing:

• Reduces taxes
• Maintains market exposure
• Improves after-tax returns
• Easy to implement

Potential benefit: 0.5% - 1.5% annually in after-tax returns

Action Plan

1. Review taxable accounts for unrealized losses
2. Calculate potential tax savings
3. Identify suitable replacement investments
4. Execute sales and purchases (mind 31-day rule)
5. Track cost basis and carry-forward losses
6. Consider automation for hands-off approach

Remember: Don't let the tax tail wag the investment dog. Harvest losses opportunistically, but maintain your long-term investment strategy.
