How many clients do you have that owe the IRS more than $51k in back-taxes? If so, the State Department can revoke your passport entirely or decline to renew until taxes are paid off or you enter into a repayment plan. See IRS Notice Here
Would that be a stay violation? Hmmm, maybe not under 362(b)(9) and (26)? Perhaps it can be argued that it is not an act to collect against the debtor at all? hmmm I’ll punt on this!
