Are you doing your summer cleaning and wondering if you can throw out some of those old tax records? If you are like most taxpayers, you have records from years ago that you are afraid to throw away. It would be helpful to understand why you keep the records in the first place.


Generally, we keep “tax” records for two basic reasons: (1) in case the IRS or a state agency decides to question the information reported on our tax returns, and (2) to keep track of the tax basis of our capital assets so when we actually dispose of them we can minimize the tax liability.

With certain exceptions, the statute for assessing additional tax is three years from the return due date or the date the return was filed, whichever is later. However, the statute of limitations for many states is one year longer than the federal.

In addition to lengthened state statutes clouding the recordkeeping issue, the federal three-year assessment period is extended to six years if a taxpayer omits from gross income an amount that is more than 25 percent of the income reported on a tax return. And of course, the statutes don’t begin running until a return has been filed. There is no limit where a taxpayer files a false or fraudulent return in order to evade tax.

Examples - Sue filed her 2004 tax return before the due date of April 15, 2005. She will be able to dispose of most of her records safely after April 15, 2008. On the other hand, Don filed his 2004 return on June 2, 2005. He needs to keep his records at least until June 2, 2008. In both cases, the taxpayers may opt to keep their records a year or two longer if their states have a statute of limitations longer than three years. Note: If a due date falls on a Saturday, Sunday or holiday, the due date becomes the next business day.

The big problem! The problem with the carte blanche discarding of records for a particular year because the statute of limitations has expired is that many taxpayers combine their normal tax records and the records needed to substantiate the basis of capital assets.

They need to be separated, and the basis records should not be discarded before the statute expires for the year in which the asset is disposed. Thus, it makes more sense to keep those records separated by asset. The following are examples of records that fall into that category:

• Stock acquisition data - If you own stock in a corporation, keep the purchase records for at least four years after the year the stock is sold. This data will be needed in order to prove the amount of profit (or loss) you had on the sale.

• Stock and mutual fund statements – Many taxpayers use the dividends they receive from a stock or mutual fund to buy more shares of the same stock or fund. The reinvested amounts add to the basis in the property and reduce gain when it is finally sold. Keep statements at least four years after final sale.

• Tangible property purchase and improvement records - Keep records of home, investment, rental property, or business property acquisitions AND related capital improvements for at least four years after the underlying property is sold.

When discarding old records, don’t forget about identity theft problems. Be sure to shed or burn the documents or portions of those documents that contain sensitive information such as Social Security Numbers, account numbers, addresses, etc.
