You must keep your records as long as they may be needed for the administration of any provision of the Internal Revenue Code. Generally, this means you must keep records that support items shown on your return until the period of limitations for that return runs out.
The period of limitations is the period of time in which you can amend your return to claim a credit or refund or the IRS can assess additional tax. Table 3 contains the periods of limitations that apply to income tax returns. Unless otherwise stated, the years refer to the period beginning after the return was filed. Returns filed before the due date are treated as being filed on the due date.

Keep 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 your basis for computing gain or loss when you sell or otherwise dispose of the property.
Generally, if you received property in a nontaxable exchange, your basis in that property is the same as the basis of the property you gave up. You must keep the records on the old property, as well as the new property, until the period of limitations expires for the year in which you dispose of the new property in a taxable disposition.taxmap/pubs/p552-002.htm#en_us_publink10008616
When your records are no longer needed for tax purposes, do not discard them until you check to see if they should be kept longer for other purposes. Your insurance company or creditors may require you to keep certain records longer than the IRS does.
