Biggest thing would be having a primary account that treasury doesn’t have ACH on..

Hmmm. Good point and probably protecting the information is the bigger issuer. Im hearing rumblings of “loyalty tests”. I think paying with a cc should be okay. So keep account where paycheck is deposited but have a second account to transfer $$ into that gov dosesnt access to?

I haven’t. Are you thinking to move your paycheck out of the ACH acct to one that the gov doesn’t have access to? Should be pretty easy to do
