Basic records are documents that everybody should keep. Although the Internal Revenue Service doesn't require you to keep your records in a particular way, it does urge taxpayers to keep them "in an orderly fashion" and in a safe place.

How long you should hang on to

IF you ... THEN the period is ... Owe additional tax and situations 2, 3 and 4 (below) do not apply to you 3 years Do not report income that you should and it is more than 25 percent of the gross income shown on your return 6 years File a fraudulent return No limit Do not file a return No limit File a claim for credit or refund after you filed your return Later of 3 years or 2 years after tax was paid File a claim for a loss from worthless securities 7 years

Also keep in mind that while the basic IRS review period is three years, there are exceptions -- in the tax collector's favor.

If the agency suspects you've underreported your income or has questions about a worthless stock write-off, look out. When examiners believe you've shorted your income amount on a return by 25 percent or more, they can come asking questions up to six years later. Add another 12 months for queries about that bad investment.

More details on tax record keeping are available in IRS Publication 552, Recordkeeping for Individuals.
