My paycheck hasnt been withholding federal tax. Im NOT marked as exempt. I have 2 dependants and I marked myself head of household. What am I doing wrong?

Check with your employer.  Perhaps your W-2 income is too low to require withholding, or your employer made an error.

I have contacted them 4 times and they are zero help. They say it's something that I put on my W4 and told me that I should contact a tax professional. I am so frustrated by all of it. They take zero responsibility for everything and say it was something that I did. I make $18 an hour
