I saw that circulated when it was posted but I have not personally seen any clients hit with an IRS crypto audit. The IRS recently put out an RFP for assistance in calculating basis so I think they are a ways away from mass audits of individual taxpayers. The audits I have seen in this space were entities. Based on discussions with IRS and Treasury officials this list would seem overly detailed for their capabilities and current enforcement targets.
are you a CPA? do you have a considerable number of clients investing in crypto?
re "they are a ways away from mass audits" i tend to agree. the document published by CryptoTrader.Tax indicates they are still way behind the curve, and still need to figure out how to make crypto audits even remotely affordable.
the 2019 tax return check box and mass letter campaigns were probably just scare tactics intended to deter noncompliance in the meantime.
