I haven't changed my w4 for the 15 years that I have been with the same employer. I claim 3 allowances and have always gotten back a decent amount which I use to help pay my mortgage throughout the year. Over the 15 years, I had a baby, my oldest child turned 18, and my mom passed away, who I claimed as a dependent on my taxes. Last year, my oldest child moved out, my middle child turned 18, and my baby turned 11 in January of this year. I started a part time job in February working about 8 hours a week. Should I change my w4 and if so, to what? I still need to get back enough to help me with the mortgage but also have enough during the week to survive on.
