Understanding Capital Gains Tax
📅 Holding Period Matters
The length of time you hold an asset determines your tax rate:
- Short-term: Assets held for 1 year or less are taxed as ordinary income (10-37%)
- Long-term: Assets held for more than 1 year qualify for preferential rates (0%, 15%, or 20%)
💡 Deductible Expenses
You can reduce your capital gain by deducting:
- Brokerage commissions and trading fees
- Transfer taxes and recording fees
- Real estate improvements (not repairs)
- Investment advisor fees directly related to the sale
🏠 Special Rules
Primary Residence: You may exclude up to $250,000 ($500,000 married) of capital gains if you've lived in the home for 2 of the last 5 years.
Net Investment Income Tax (NIIT): An additional 3.8% tax may apply to capital gains if your income exceeds $200,000 (single) or $250,000 (married).
Cryptocurrency: The IRS treats cryptocurrency as property, subject to capital gains tax.
📉 Capital Losses
If you sell an asset for less than you paid:
- You can use losses to offset capital gains
- Up to $3,000 of excess losses can offset ordinary income
- Remaining losses can be carried forward to future years
