Even if you’re a taxpayer with simple returns and few supporting documents, you can become a little snowed under by tax records as they accumulate over the years, raising the question of how long you should hold on to such records. The answer depends on the types of documents and transactions involved, but if you have been a tax records pack rat for many years, chances are you can safely dispose of the oldest such records without inviting trouble.
As a starting point, you must keep tax records that support the income, deductions, and credits on your tax return, and you should also keep copies of the returns themselves. As for how long to retain the records, a good rule of thumb is to keep them until the limitations period runs out for the return in question.
The “period” refers to the amount of time you have to amend a return to claim a credit or a refund or in which the IRS can assess additional taxes. As a general rule, the limitations period for a return is three years after it has been filed, but if you file early, the period runs from the date the return was due to be filed.
For most general rules there are exceptions, and that is the case with keeping tax records. If you failed to report income in an amount that is more than 25% of the gross income shown on your return, keep the records for six years, not three. If you filed an amended return to get a credit or re-fund, keep the records for either three years from the date you filed the original return or two years from the date you paid the tax, whichever is later.
After filing a claim for a loss from worthless securities or a bad-debt deduction, hang on to any relevant re-cords for seven years. Employers should retain all employment tax records for at least four years after the tax was due or has been paid, whichever is later.
If you did not even file a return or filed a fraudulent return (it has been known to happen), all of the above rules are out the window, because the limitations period never expires. Keep those records indefinitely. Also, even if you did not amend a return, some types of records should be kept for extended periods. Among the records in this category are those relating to securities and real estate, nondeductible contributions to retirement accounts, and home improvement expenditures.
For the space-conscious among us, the good news is that retaining even voluminous amounts of tax records these days may not have to take up any more room than the space occupied by your computer. The IRS allows taxpayers to store tax documents electronically, whether they originated electronically or on paper.
