I made $22,000 last year and paid $1900 in federal taxes. I work with two other guys who both made less than me and paid less taxes, but they got double the money on their tax return as I will get. I haven't filed yet, but every website I go to tells me I'll get $577 back. They both went to Walmart and had someone else do their taxes for them and got over $1000. None of us have any kids or other credits that would boost their credit returns. The only thing different is that I made more money and paid more taxes, yet I'm getting half as much as they got. How does that make sense?
