Would this be corroborating evidence?
Zietzke v. United States, January 2020
In its request number two, the IRS seeks:
All customer identification program records (such as Know Your Customer (KYC) or Customer Due Diligence (CDD) records) relating
the Taxpayer and Covered Accounts, including, but not limited to, identifying information such as date-of-birth, physical address, social security number or other tax-identification number, passport, driver's licenses or other government-issued identification, Taxpayer photographs, income/employment information, customer explanation of activity information, third-party identification verification reports, and any other information used to verify or confirm identity.
Request No. 6 requests:
[a]ll account history information . . . for transactions or events relating to any Covered Accounts, including, but not limited to the type of transaction . . ., party and counter party names, digital wallet information, blockchain addresses, transaction ids, and any other information related to the identity or location of the parties involved.
(Dkt. No. 1-2 (Request No. 6).) Request No. 8 requests:
[a]ll contact information for individuals or entities . . . associated with any transactions involving any Covered Accounts, including, but not limited to, name, user name, address, telephone number, transaction id, and identification information.
(Dkt. No. 1-2 (Request No. 8).) Request No. 9 requests:
[a]ll documents and information relating to any payment or transfer to or from any Covered Accounts, including, but not limited to, counterparty name, account, user name, physical mailing address, email address, website, checks, wires, electronic transfer information, ACH, PayPal, money orders, prepaid card information, or any other form of payment information.
We previously issued Information Document Requests for information pertaining to virtual currency holdings as follows:
• The Information Document Request #1 requested "Virtual Currency activity statement for the period of 1/01/2016 through 12/31/2016, if available. If no virtual currency activity statement is available, please make available your spreadsheets, schedules, ledgers or other records used to track your virtual currency balance, transactions, etc."
• The Information Document Request #2 requested "Print out the block chain transactions for all wallet addresses owned with the explanation of all the transactions for the period under exam."
Furthermore, held phone conferences on the following dates as well to resolve this tax matter: 10/15/2018, 11/15/2018, 12/17/2018, 2/15/2019, 2/28/2019.
The IRS apparently used Chainalysis to identify where Zeitke moved bitcoins:
We have reviewed the information provided by [Petitioner] with respect to his Bitcoin transactions during 2016. Based on the information and his explanation during our telephone conference, there are still some uncertainties with respect to his activities during the 2016 tax year. For example, [Petitioner] indicated that all of his Bitcoin holdings were essentially split between the coins held in his personal wallets managed through the Armory software and the coins that he acquired through Coinbase and disposed of through Coinbase or Purse.io.
[Petitioner] explained that the none of the coins held through the Armory wallet were disposed of during 2016 and that all of the coins disposed of during 2016 came from acquisitions made through Coinbase. This is not true. Based on the transaction ids provided with the Purse.io information, we were able to locate those transactions on the Bitcoin blockchain and the address from which the coins were sent to Purse.io are not related to Coinbase. We were able to link some of those addresses with wallets associate with both Bitstamp and BTC-e, which are/were cryptocurrency exchange platforms similar, but unrelated, to Coinbase.
I can't seem to find the summons that the IRS sent to Coinbase, or Revenue Agent Snow's declaration. Are those attached or linked somewhere? Though what can be seen in Casetext alone is already very close to the same type of information as in that Reddit letter.
