Don't pay these thieves anything. This is bad advice. But there is a book out there outlining how many people have avoided taxes by writing a legal letter to the IRS.

The IRS is unconstitutional, and globalist illegal operation. Even worse seeing our hard earned money going to pay off their cronies. Fuck them.

You have to establish a cost basis for each coin you bought (Price plus fees) and subtract that from what you sold it for. If you swapped them back and forth it gets confusing but most wallets you use will have a record of your transactions. So if you bought 100$ worth of bitcoin and it goes up to $120 and you swap it for ether you have $20 capital gains(minus fees). The value if ether at the time you bought it is the new cb and so on. Short term if you held less than 1 year.

Don't panic - read the tax form on income reporting carefully - get the paper manual, or use an online tax filing product like Turbo Tax. They explain what the IRS doesn't - much of this is not considered income or dividends by the IRS.

Just sign up for an online crypto tax service, they'll do all the work. Provide any accounts and wallets and they can quickly create all the forms you need after scanning the blockchains for your trades.

I didn’t even think about it here the gov knows about your crypto and the exchanges report capital gains to them and we get a paper showing our gains/losses and there’s a box for it on the tax return form
