Why do I owe Taxes ?

The reason people owe taxes can vary, but the most common reason is the Withholding form. Yes the form you receive before employment at every job, that you just rush through to get started. However, it is important to note that this has an effect on the amount you owe, you have to pay a certain percentage based off income. I suggest filling this form out properly after your first two paychecks. Here is an attached site to help you calculate your withholding: Tax Withholding Estimator | Internal Revenue Service (irs.gov)
