Frequently Asked Questions
How is cryptocurrency taxed?
Cryptocurrency is treated as property by the IRS. Selling, trading, or spending crypto triggers a capital gains event. Short-term gains (held under 1 year) are taxed as ordinary income. Long-term gains (held over 1 year) get preferential rates of 0%, 15%, or 20%.
What is the Net Investment Income Tax (NIIT)?
The NIIT is an additional 3.8% tax on investment income (including crypto gains) for taxpayers above certain thresholds: $200,000 for single filers, $250,000 for married filing jointly, and $125,000 for married filing separately.
Can I deduct crypto losses?
Yes. You can deduct up to $3,000 in net capital losses per year against ordinary income. Losses exceeding $3,000 carry forward to future tax years. Unlike stocks, crypto is not subject to wash sale rules (as of 2025).
