Primary Residence Sale, Need to report on taxes?

[Adam Johnson]

I bought my house in 2009, and sold it in 2015 (lived in it the entire time). I profited less than 100,000 on the sale. Am I required to put this sale on my tax return?

I think the answer is no, and all that profit is tax-free....but it feels too good to be true, and wanted to hear it from the experts.
