Kiplinger's attempts at financial journalism from a right-wing perspective are always good for a few laughs.  Take what they say with a grain of salt.  For example, "Generally, after September 30, 2025, the Treasury Department has said that all federal agencies will cease sending and receiving paper checks as a form of payment."  Where did they say that?  If you Google that statement, it will send you back to the Kiplinger story.  Or, it will send you to this notice from the Bureau of Fiscal Service, which says nothing about accepting paper checks.
