Free Guide: How Long to Keep Your Tax Returns

Why Tax Return Storage Matters

Keeping your tax returns organized and stored safely is an important part of managing your financial records. Tax returns contain sensitive personal and financial information, including your Social Security number, income details, and banking information. Understanding how long to keep these documents protects you in several ways.

The Internal Revenue Service (IRS) may contact you about a return you filed months or years ago. If you don't have a copy, you won't be able to respond effectively or verify the information you reported. Additionally, various government agencies, financial institutions, and creditors sometimes request copies of your tax returns to verify your income or financial status. Having these documents readily available saves time and prevents complications.

Tax returns also serve as proof of your income history, which matters when applying for loans, mortgages, or rental housing. Employers or government programs may request past returns. Beyond these practical reasons, the IRS has specific rules about how long taxpayers must retain returns and supporting documents. These are not suggestions—they are legal requirements that vary based on your circumstances.

This guide explains the general timelines the IRS recognizes and the specific situations that may require you to keep returns longer. Understanding these rules helps you maintain compliance while knowing when it's safe to dispose of older records. Proper storage and organization make it much easier to locate returns when you need them.

Practical Takeaway: Create a system for storing your tax returns that works with how you manage other important documents. Whether you use a filing cabinet, storage box, or digital folder, consistency matters more than the method itself.

The Basic Three-Year Rule

The most common guidance the IRS provides is to keep tax returns and supporting documents for at least three years. This three-year period runs from the date you filed your return or the return's due date, whichever came later. For most people in straightforward situations, this is the minimum timeframe recommended by the IRS.

Why three years? The IRS generally has three years from the date a return is filed to examine your return and propose changes. This period is called the statute of limitations. During this window, the IRS can request documentation, ask questions about deductions or income, or assess additional taxes if they find errors. If you cannot produce your records during an audit, you'll have difficulty defending the numbers on your return.

The three-year timeline applies to most common returns and situations. If you filed a return in April 2023, you should keep all related documents—the completed tax form, receipts, bank statements, and anything else that supports your reported income and deductions—through April 2026. After that date passes, many people choose to discard these records, though keeping them longer creates no harm.

However, three years is not a universal rule. Certain situations require longer retention periods. If you received income you did not report, or if you claimed deductions that may raise questions, you might need documents beyond the three-year mark. Similarly, if you're self-employed or own a business, additional requirements often apply. The sections below explain these exceptions in detail.

For digital storage, three years means having a reliable backup system. Hard drives fail, and cloud services shut down. Making multiple copies of important returns and storing them in different locations reduces the risk of losing records when you need them most.

Practical Takeaway: Mark your calendar three years after filing each return. This date reminds you when you can safely dispose of most supporting documents while maintaining compliance with IRS guidelines.

Extended Timelines: When to Keep Records Longer

Several situations require keeping tax returns and supporting documents for longer than three years. Understanding these circumstances ensures you don't prematurely discard records you may need. The IRS outlines these extended requirements clearly, though the specifics depend on your tax situation.

If you underreported your income by more than 25 percent, the IRS extends the statute of limitations to six years. For example, if your actual taxable income was $50,000 but you reported only $37,500, you've underreported by 25 percent. In this case, keep your return and all supporting documents for six years from the filing date. This gives the IRS additional time to examine your records if they discover the discrepancy.

If you did not file a return at all for a tax year, there is no statute of limitations. The IRS can examine records and assess taxes indefinitely. If you eventually file a return for a year you missed, retain those documents for at least six years. This protects you if questions arise about why the return was filed late or what income you included.

Self-employed individuals and business owners face different requirements. Business records—including invoices, receipts, payroll documents, and expense records—should be kept for at least six years. Many tax professionals recommend keeping business records for seven years to provide a safety margin. These records support the income and deductions you report on your business return, so losing them can create serious problems during an audit.

If you claim depreciation on business assets or rental property, keep those records and the related tax returns for at least six years after the asset is sold. The cost basis and depreciation history matter for calculating gains or losses when you dispose of the property. Investment property records require similarly long retention periods.

Records related to home improvements and mortgage interest should be kept for at least three years after you sell your home, and potentially longer if you claimed exemptions from capital gains taxes. If you received tax credits like the earned income credit or education credits, keep supporting documents for three years minimum, though some recommend longer retention for greater security.

Practical Takeaway: Review your specific tax situation and identify which extended timeline applies to you. Document this information and set calendar reminders for when each category of records can be safely discarded.

Self-Employed and Business Owner Requirements

Self-employed individuals and business owners operate under stricter record-keeping rules than salaried employees. The IRS places greater emphasis on business records because they form the foundation of business income calculations and deduction claims. Understanding these requirements is essential for anyone with self-employment income, a side business, or ownership interest in a company.

Business tax returns should be retained for at least six years, and many accounting professionals recommend seven years as a safety margin. This includes all supporting documentation: invoices you issued to customers, receipts from business expenses, bank statements, payroll records, mileage logs, and inventory records. Every number on your business return should be traceable to underlying documentation. If the IRS audits your business, you'll need to produce these documents to support your claimed income and expenses.

Mileage records deserve special attention because they're frequently audited. If you deduct vehicle expenses based on actual miles driven, maintain detailed logs showing dates, destinations, business purpose, and miles traveled. The IRS wants specific information, not general estimates. These records should be kept for at least six years alongside your return. Contemporaneous written documentation—created at the time you drove, not reconstructed later—carries more weight during an audit.

Meal and entertainment expenses have historically faced IRS scrutiny. If you deduct these costs, keep receipts and documentation showing the date, location, amount, attendees, and business purpose for six years. A credit card statement alone is insufficient; you need itemized receipts showing what you purchased.

If your business carries inventory, maintain detailed records of beginning inventory, purchases, and ending inventory for each tax year. These calculations determine your cost of goods sold, which significantly affects reported income. Inventory records should be retained for six years minimum. If you've been audited in the past for inventory discrepancies, consider keeping these records even longer.

Employment records require special attention. If you have employees, maintain payroll records, tax withholding information, and W-2 copies for at least six years. The IRS can examine payroll records to verify that you properly withheld and paid employment taxes. These records include timesheets, wage information, tax deposits, and year-end reconciliation documents.

Practical Takeaway: Establish a filing system specifically for business records that separates each tax year. Color-coding or clearly labeling folders by year makes it easier to locate specific records quickly if you're audited or need to reference past business activity.

Investment and Property Records

Tax returns involving investments and real property require special record-keeping attention because they often span multiple years and affect future tax calculations. These documents track cost basis, depreciation, and capital gains or losses, which matter long after the original
