Publication 225
taxmap/pubs/p225-003.htm#en_us_publink1000217648You must keep your records as long as they may be needed for
the administration of any provision of the Internal Revenue Code. Keep records
that support an item of income or a deduction appearing on a return until the
period of limitations for the return runs out. A period of limitations is the
period of time after which no legal action can be brought. Generally, that means
you must keep your records for at least 3 years from when your tax return was
due or filed or within 2 years of the date the tax was paid, whichever is later.
However, certain records must be kept for a longer period of time, as discussed
below.

for at least 4 years after the date the tax becomes due or is paid, whichever is
later.
taxmap/pubs/p225-003.htm#en_us_publink1000217650Keep records relating to property until the period of limitations
expires for the year in which you dispose of the property in a taxable
disposition. You must keep these records to figure any depreciation,
amortization, or depletion deduction and to figure your basis for computing gain
or (loss) when you sell or otherwise dispose of the property.
You may need to keep records relating to the basis of property
longer than the period of limitation. Keep those records as long as they are
important in figuring the basis of the original or replacement property.
Generally, this means as long as you own the property and, after you dispose of
it, for the period of limitations that applies to you. For example, if you
received property in a nontaxable exchange, you must keep the records for the
old property, as well as for the new property, until the period of limitations
expires for the year in which you dispose of the new property in a taxable
disposition. For more information on basis, see
chapter 6.

discard them until you check to see if you have to keep them longer for other
purposes. For example, your insurance company or creditors may require you to
keep them longer than the IRS does.
