I am a 22 y.o. recent college graduate, living back at home with parents. I am claimed as a dependent under them for taxes. I just landed my first job as a part-time, as needed employee (per diem, essentially) with an hourly wage of $18/hr. How many allowances should I claim? 0 or 1? Ideally, I would like to have a higher take home pay without owing any taxes at tax return period (a smaller refund or none is fine with me). What option is most suitable?
