Id need more than that though. Other income you dad, taxes paid, charity, mortgage income etc. The way the irs usually thinks is ok you make 100k a year. In addition you have 1k of income unexplicably in your bank. That's 1% of other income and is reasonable. Now if you report $5k in income and have $1k in other that looks more suspicious. They like percentages and comparing it to the industry average.
