The IRS has lost two prominent directors focusing on cryptocurrency efforts, Seth Wilks and Raj Mukherjee, after they accepted voluntary resignation offers on Friday directed by the Department of Government Efficiency.

Wilks and Mukherjee, both of whom transitioned from the crypto sector to the IRS, remain on administrative leave while technically employed for a few more months, as two sources informed CoinDesk. Earlier this year, President Donald Trump’s administration extended deferred resignations to a large number of federal workers through various initiatives.

Wilks, formerly a vice president at TaxBit, and Mukherjee, who previously held senior positions at ConsenSys and Binance.US, joined the IRS Digital Asset Initiative in February 2024. They were instrumental in the IRS’s plans to implement improved strategies for cryptocurrency taxation, including the establishment of effective reporting and compliance measures and collaboration with the crypto industry. They also worked on a revised 1099-DA tax form intended to assist U.S. taxpayers dealing with digital asset transactions.

Furthermore, they contributed to the creation of tax guidelines specifically for the cryptocurrency sector, with one recent rule regarding data collection duties imposed on decentralized finance (DeFi) brokers, which was ultimately rejected by Congress in a resolution signed by Trump.

Both officials opted for voluntary buyouts ahead of anticipated staff reductions within the IRS, with reports indicating over 20,000 IRS employees signed up for the deferred resignation scheme.
