<prompt> Human: I just tried using HR Blocks E-file program, worked all year at a warehouse full time with health insurance. Earned 31,000, paid 4500 in taxes so far. No dependents, no deductions, and apparently it says i owe the federal government another 7500. I did not submit them because I want to meet with some one who knows more about taxes than I do before filing. Should note i made 29000 last year and got a 1000 refund, and didnt change my withholdings. On the plus side though my state return is almost 400... so theres that I guess. So what Im asking is did I screw up somewhere or what happened?  <response>: I come up with 1800 refund based on what you said. EDITMY MATH: 31000 - 10150 20850. 20850 on the tax table is 2663 . 4500 - 2663 1837.disclaimer - I am not a tax professional-or even very good at math.
