Before you worry, I used a burn box that was sitting in my fire pit. What did I burn? Tax
returns from 2003-2017. Here are the rules from the IRS on how long you should keep
them:
Period of limitations that apply to income tax returns.
Keep records for 3 years if situations (4), (5), and (6) below do not apply to you.
Keep records for 3 years from the date you filed your original return or 2 years from the date
you paid the tax, whichever is later, if you file a claim for credit or refund after you file your
return.
Keep records for 7 years if you file a claim for a loss from worthless securities or bad debt
deduction.
Keep records for 6 years if you do not report income that you should report, and it is more
than 25% of the gross income shown on your return.
Keep records indefinitely if you do not file a return.
Keep records indefinitely if you file a fraudulent return.
Keep employment tax records for at least 4 years after the date that the tax becomes due or is paid, whichever is later.

It was so cathartic and now I have an empty cupboard!
