Fork Tax FAQ
I held BTC during the BCH fork but never claimed - do I owe tax?
Not yet. If your BCH is sitting unclaimed on an exchange or you haven't imported keys, you haven't "received" it. Tax triggers when you gain access.
What if I can't find the price at the fork date?
Use CoinMarketCap or CoinGecko historical data. The IRS wants FMV at the time you received access, not the fork announcement date.
My exchange gave me fork coins months later - which date counts?
The date your exchange credited them and you could withdraw/trade. That's when you gained dominion and control.
Is a soft fork taxable too?
No. Soft forks don't create new coins. Only hard forks that split the chain and give you new tokens are taxable events.
What if the fork coin immediately crashed?
You still owe income tax on the value when received. But if you sell at a loss later, you can use that capital loss to offset gains.
Multiple forks from same coin - how to track?
Each fork is a separate income event. BTC had dozens of forks. Most were worthless, so $0 income. Only valuable ones matter for taxes.
Fork vs airdrop - what's the difference?
Forks split an existing chain. Airdrops distribute new tokens. Tax treatment is similar - ordinary income at FMV when received. But airdrops can be unsolicited.
Can I avoid fork taxes by not claiming?
Yes, but you forfeit the coins. Some forks have claim deadlines. Weigh the tax cost vs. potential value before deciding.
