This law will get tossed by the courts state law does not overrule federal law and there is no federal law requiring one to release their tax returns as a requirement to run for President.
I don't think it will stand but there is no requirement that a candidate get X amount of signatures either but that is how it works.
That's to reasonably limit the pool so they don't have to print 10-page ballots with everybody on it who has no chance in hell to get more that 100 votes.
That is a completely different issue.
