This year, numerous popular crypto platforms have shut down. This has affected an increasing number of crypto users. One of the significant effects of these shutdowns is the tax implications. It's extremely important, if the exchange still allows it, to export a history of your transactions. In fact, you should make a habit of exporting your transaction history from every exchange you use, on a regular basis. This ensures that you will always have access to your transaction history, even if an exchange shuts down permanently. These records are 100% necessary for calculating your crypto taxes.
You can find a list of instructions for exporting data from specific exchanges here.
These instructions are also available on your Bitcoin.Tax account, via the Trading Tab and Income Tab.
