Can your employer take taxes from your check if you have never filled out a w-2 or w-4?

I started this new job about a month ago. They told me to bring in my id and social security card, But they never took it or allowed me to fill out my tax info. They have been taking almost a hundred dollars from my check and they have me down as filling single but I never did that. How can they assume how much taxes to take from ones check. I never gave them as much as my id or social security info. It's as if I don't even exsist with this major company.....My question is, is this legal!

Just because you never gave them your ID's, I bet that you put your SSN on your job application.

If you don't give them a W-4, they withhold tax at the highest rate available.

Actually, I'm surprised they are letting you work without this information.

BTW, it's legal.

Go to irs.gov. Get a W-4. Fill out and turn it in.

When you don't file the form they are supposed to assume SINGLE-0, which is the highest amount withheld. (Yes, this is very legal.)

When you file a new W-4, it takes effect the next pay period. (You will get any excess money back when you file your taxes.)

If you never gave them your ID/SSN, you are lucky they haven't been withholding 30% and telling you that you were fired. (This is what companies do when they find they hired an illegal alien.)

I'm sure employers can treat you as single with one exemption in absence of you completing a W-4 form. If that is incorrect, why not simply provide the correct information to your employer?

there not even suposed to send you a check if you havent filled one out you need to do it right away so you dont get in deep dudu

Sounds like the employer is more concerned about doing right by you than you are about doing right by them. Get a W-4 fill it out and be glad they did not fire you as without a ss number they are subject to IRS fines and have grounds to can you. If they have withheld extra, enjoy your refund and file a corrected form W-4 with them and forget about it.

It's not only legal, but required. If you don't fill out a W-4 and give it to them, they are required to take out as if you'd filed single/zero allowances. Get the form to them, along with your social security card.

Technically they shouldn't be paying you at all until they see proper ID from you.
