It ' s hard to answer your question without more details . It depends on how you were classified during the internship as an employee or independent contractor , how much income you had throughout the rest of 2016 , and whether you are a dependent . Assuming you were an employee and this was your only source of income in 2016 , you made about $ 18 k and paid roughly $ 6 k in taxes . I assume 3 k or so were federal taxes and the rest were stateFICA ? If you are a dependent , you had about $ 12 k in taxable income and were liable for ~$ 1400 in federal taxes . If you were not a dependent , you had about 8 k in taxable income and were liable for ~$ 800 in federal taxes . I . e . If this was your only income you are probably eligible for a refund of $ 1500 , but it ' s impossible to know without knowing all the details of your incomestatusdeductible expenses .
