How long should I keep my tax documents, and why?
Unfortunately, my taxes tend to be complicated This. In and of itself, is a greater reason to keep the documents. The other answer offered a good summary, but keep in mind, if the IRS decides you fraudulently withheld claiming income, they can go back 7 years.  I bought a rental property in 1987, and sold it in 2016. In that case, keeping the returns seemed the right thing to do to have the paper trail for basis, else I could claim anything, and hope for the best.  I have all my tax returns since my first tax return, 1980. It's one drawer of a file cabinet. Not too great a burden.
