CPA for Reconciliation? Incomplete history
I started buying crypto in 2017, I made a lot of trades. Coinbase, Binance, Kucoin. I exported my trades. I have approximately 1,450 total trades, most are weekly DCA buys and not taxable events. The challenge is, over the years I've changed wallets, especially each time some event happened (ex: ledger and lately, coldcard). I don't have those wallets anymore. I also had trades where I may have sent from coinbase to a wallet, from wallet to binance, made trades, send back.
I've submitted taxes honestly when trades occur, I have my 8949s for all applicable years. My records for the past 4-5 years are quite clean. I'd say 60-70% of my holdings has a reasonable cost basis. As of the past 1-2 years it's been 100% BTC.
I don't think the crypto tax software can address this. It's just going to leave me guessing. I assume the path is establish reliable cost basis for as much as I can, and just state basis as $0 for what I can't?
From this point forward I'm only buying into an ETF, so this will remain a problem, whether I get it solved tomorrow or 5 years from now.
Is a CPA the way to go? What would this even cost? I'm going to chat with a few crypto friendly CPAs over the next week. I'd love feedback from people not trying to sell me on their services, if possible.
