How Long Should You Keep Your Tax Records

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 that the tax liability can be minimized when we actually dispose of the assets.

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% 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 on the assessment period where a taxpayer files a false or fraudulent return in order to evade tax.

If an exception does not apply to you, for federal purposes, most of your tax records that are more than three years old can probably be discarded; add a year or so to that if you live in a state with a longer statute.

For example: Sue filed her 2011 tax return before the due date of April 17, 2012. She will be able to dispose of most of her records safely after April 15, 2015. On the other hand, Don files his 2011 return on June 2, 2012. He needs to keep his records at least until June 2, 2015. 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 discarding records indiscriminately for a particular year once 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 this 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 that 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 gains when the stock is finally sold. Keep statements at least four years after the 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.
