Well I m starting into my first “real” job in which I get paid by check with all tax deductions taken out for my first check I had a gross income of $7,510 and with all deductions my net pay came to be $4,000, these numbers change from check to check but I will end up making $100,000 but I will get around 30k withheld from my checks this year I m single with no dependents can I expect to owe the IRS money at the end of the year or could I get some money back. thanks and sorry for such a long question.
