FAQ

Frequently asked questions.

Do I have to pay taxes on crypto?

Yes. The IRS treats cryptocurrency as property. Selling, trading, or spending crypto triggers a taxable event. You must report capital gains and losses on your tax return.

How is crypto taxed?

Short-term gains (held <1 year) are taxed as ordinary income (10-37%). Long-term gains (held >1 year) are taxed at preferential rates (0%, 15%, or 20%). Losses can offset gains.

Is this calculator really free?

Yes. The Observer tier includes crypto tax tracking, capital gains calculation, and basic Form 8949 generation at no cost. Premium tiers add advanced features like tax-loss harvesting alerts.

What exchanges do you support?

Currently Coinbase and Binance via encrypted API connections. Bank and brokerage accounts connect via Plaid. More exchanges coming soon.

Can I use this for DeFi transactions?

Fortress tracks DeFi positions for supported protocols. Swap, liquidity pool, and yield farming transactions are imported and classified automatically.

Will this work for my CPA?
