The original post didn't say "that do not charge tax." Yes you must pay taxes where applicable, like all purchases.

He asked which laws he might have unintentionally broken. Unless he's an incredibly literate 6 year old... I suspect he's old enough to have sung happy birthday before 2016, which would have been breaking the law.
