People now get one to two hours less sleep each night, on average, compared to 60 years ago. A primary reason for this is the proliferation of electronics, which also allows us to work (and play) later than ever before.
The Internal Revenue Service requires that individuals be able to produce records proving any income, deductions or credit claimed for at least three years from the date of a return, the statute of limitations for how long the I.R.S. has to assess additional tax if all income was reported correctly.
How long should I keep tax returns? In most cases, you should plan on keeping tax returns along with any supporting documents for a period of at least three years following the date you filed or the due date of your tax return, whichever is later. So for example, if you filed your 2015 tax return on February 1, 2016, you should have kept the return and supporting documents until at least April 15, 2017. What tax records should I keep? You should keep every tax return and supporting forms. This includes W-2s, 1099s, expense tracking, mileage logs if you itemize and other documents.
