Employer never took out my state taxes??

I worked as a server from June-December 2021 and recently did my taxes with the W-2 they sent me only to find out that they never took my state taxes out of each paycheck! I never caught this before because we didn’t get physical pay stubs and never knew the password to the website where I could access it. Now I owe more than I’m getting back all because they never bother to take out enough money! How is this legal it seems sooo fucked up to me
