How Long Must You Keep Your Tax Returns?

Maintaining tax records is an important aspect of personal financial management. They allow individuals to verify reported income, deductions, and credits, and are essential for responding to inquiries or audits from tax authorities. Keeping these documents helps ensure compliance and can prevent issues if questions arise about past tax filings.

Federal Income Tax Return Retention Periods

The length of time to keep federal income tax returns varies depending on your specific tax situation. The Internal Revenue Service (IRS) has a statute of limitations during which it can assess additional tax or you can claim a credit or refund. This period defines how long you need to retain your records.

For most tax returns, the standard rule is to keep records for three years from the date you filed the original return or the due date, whichever is later. This period is established under Internal Revenue Code Section 6501. If you filed your return before the April 15 due date, the three-year period begins on April 15. This timeframe allows the IRS to audit your return and assess any additional tax owed.

An extended six-year retention period applies if you omit an amount of income that is more than 25% of the gross income reported on your return. The IRS has six years to assess the tax in this situation. This extended period provides the IRS more time to identify and audit non-fraudulent returns with substantial omissions.

A seven-year retention period is required if you claim a deduction for a bad debt or a loss from worthless securities. This rule, found in Internal Revenue Code Section 6511, allows for a longer period to claim a credit or refund related to these types of losses. This extended timeframe accounts for the complexities often associated with such financial events.

In some cases, tax records should be kept indefinitely. This applies if you filed a fraudulent return with the intent to evade tax, or if you failed to file a return at all. There is no statute of limitations for assessment in these circumstances, meaning the IRS can pursue action at any time. Records related to property should also be kept for as long as you own the asset, plus the relevant retention period after its disposition, to calculate depreciation or determine gain or loss upon sale.

Supporting Documents for Federal Returns

Retaining the tax return itself is only one part of record-keeping; supporting documents are equally important. These documents provide the evidence needed to substantiate the income, deductions, and credits reported on your tax forms. They are essential in the event of an audit or any inquiry from the IRS.

Common examples of supporting documents include:
W-2 forms from employers
1099 forms for income such as interest, dividends, or independent contractor earnings
K-1 forms for partnership or S corporation income
Receipts for deductible expenses, such as medical costs, charitable contributions, or business expenditures
Cancelled checks
Bank statements
Brokerage statements detailing investment activities
Records pertaining to the purchase and sale of property

These supporting documents should be retained for the same length of time as the tax return they relate to. This ensures that if the IRS questions any item on your return, you have immediate access to the necessary proof. Organizing these documents by tax year can simplify retrieval if needed.

State Tax Return Retention Requirements

Beyond federal obligations, individuals must also consider state tax return retention requirements, which can differ from federal guidelines. While many states align their record-keeping periods with the IRS’s three-year rule, some states may impose longer or shorter requirements. These variations stem from each state’s unique tax laws and audit procedures.

States may also have specific retention rules for taxes beyond income tax, such as property tax or sales tax records for self-employed individuals. Some states might require records to be kept for four to seven years, particularly if there are complex filings involving property sales or business income. It is advisable to retain records for the longer of the federal or state retention periods to ensure full compliance.

To find the precise requirements, individuals should consult the official websites or publications of their state tax agencies. This helps avoid potential penalties and ensures all state-specific obligations are met. Checking for updates annually is also recommended, as state tax laws and retention policies can change.

Safely Disposing of Tax Records

Once the applicable retention period for tax records has passed, securely disposing of these documents is important to protect personal and financial information. Careless disposal can expose individuals to identity theft and fraud, as tax records contain sensitive data. Proper methods ensure that private information cannot be easily accessed or reconstructed.

For physical paper records, shredding is the recommended method of disposal. A cross-cut shredder is preferable, as it cuts documents into small, unreadable particles, making reconstruction difficult. Tearing or throwing away documents in the trash is risky and should be avoided. Professional shredding services offer industrial-grade machines that can destroy large volumes of documents into confetti-sized pieces, providing a higher level of security.

For digital tax records, secure deletion practices are necessary. This includes emptying recycle bins, using data wiping software for old hard drives, or physically destroying storage devices that contain sensitive information. Ensure that all copies, whether physical or digital, are thoroughly destroyed. Disposal should only occur after the longest applicable retention period for all related documents has fully elapsed, ensuring no necessary records are prematurely discarded.
