Do I have to file my tax return electronically?

All returns will be filed electronically unless you elect not to or unless your return contains a form that cannot be electronically filed. If you choose to not electronically file your return, then you must attach a form stating so.

How long should I keep my tax records?

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.
