<prompt> Human: I have been working with my employer for 3 years now and on first year, taxes were taking out correctly and got a refund of 1.5k. Second yeah comes around and i made 5k more that year and got a refund of 400. My third year i make another 5k more and i have to pay 344. Nothing has changed on any of my forms Im still single and 0 dependents etc. i talked to my employer and they said i have to talk to someone that does taxes and i went to HR Block and was told to talk to my employer. What do i do ?  <response>: Your refund is irrelevant to your tax liability. Your tax liability could have been impacted from anything from your health insurance to your 401K.
