I've had two clients who have owed tax receive the attached letter from the IRS (appears legitimate...maybe looks are deceiving).  Both confirmed that the amount due was electronically pulled accurately and timely from their bank account (which was identical to the account used on their 2024 return).  Any idea why the IRS would send this?  Neither chose to contact the IRS.  I guess I can...but wondering if anyone else has dealt with this?
