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.
These receipts and documents must be retained for at least three years. During your audit, you may be asked to supply records dating back three years if your deductions are questionable. These documents must be kept safely stored. However, if you lost your records due to fire, flooding or a natural disaster, the IRS will accept digital copies.
