Does everyone here who is judging others declare all their out-of-state online purchases on their state tax return that they didn’t pay sales tax at the time of the sale? Otherwise you’re a tax cheat.
why would you assume people don’t? What kind of view of halacha do you have that you ask these tax reporting questions as if you assume people don’t do them? I don’t hear you asking if people really bother checking for bugs or for hechsherim. why would lying on tax forms be something any less expected?
