Suggerimenti
- Holding onto an asset for just over 12 months can drastically reduce your tax rate: from your regular rate to 0%, 15%, or 20%.
- Tax-loss harvesting: sell losing positions before year-end to offset gains, but be aware of the 30-day wash sale rule.
- If you're in the LTCG slope at 0% (income below $48,350 for singles), you can sell appreciated exempt assets and re-purchase them to update the base cost.

What is the Net Investment Income Tax (NIIT)?
The NIIT is an additional 3.8% tax on net investment income (including capital gains) for high earners. It applies to the lesser of (1) your net investment income or (2) the amount your MAGI exceeds $200K (single) or $250K (married filing jointly).
What is cost basis and why does it matter?
Cost basis is what you paid for an asset. Gain = Sale Price - Cost Basis. Includes purchase price + broker commissions. For stocks, wash sale rules may affect your basis. For real estate, improvements increase basis. Accurate basis tracking is essential for tax purposes.
Can I offset capital gains with capital losses?
Yes - tax-loss harvesting. Capital losses offset capital gains dollar for dollar. If losses exceed gains, you can deduct up to $3,000 of net losses against ordinary income per year. Remaining losses carry forward to future years indefinitely.
