I just recently started a part-time job and I’m looking for info on how best to fill out my W-4. My husband works a salary job and makes the majority of our income (married filing jointly) and this part-time job that I got is just supplemental. I’ll be making probably about $400 every 2 weeks. I just received my first paycheck and no taxes were deducted, but I wasn’t sure if this was because my first check is lower than what it will normally be or if I filled out my W-4 incorrectly.
