The letters all generally are issued based on the IRS thinking you haven't disclosed your digital transactions properly. Letters sent by the IRS have a numerical identification number. They are sending 3 different letters 6173, 6174, and 6174-A. The 6173 letter is the most serious and requires a timely response under penalties of perjury. The 6174-A carries the warning that additional enforcement correspondence may follow. If the letter is asking for wallet information, balances owned, private keys, asking you to use a QR code portal enrollment, or access to your accounts, it is a scam.
