How Long Do You Keep Tax Documents?

Knowing how long to keep tax documents is important for managing personal finances. Proper record retention simplifies tax preparation, supports claims on tax returns, and provides necessary documentation for financial transactions. An organized system protects against complications and inquiries from tax authorities.

Common Retention Periods

Most tax documents should be kept for three years from the date you filed your original return or the due date, whichever is later. This is the timeframe during which tax authorities can assess additional tax. Documents under this period include filed tax returns, W-2 forms, 1099 forms, and supporting records for income, expenses, and deductions like receipts and bank statements. If you filed your return before the due date, the three-year period begins on the actual due date.

A six-year retention period applies if you substantially understate your gross income by more than 25% of the reported amount. This allows tax authorities more time to identify and review returns with significant omissions. If you claim a loss from worthless securities or a bad debt deduction, keep relevant records for seven years. These scenarios require extended retention due to their complex nature.

Specific Situations and Extended Periods

Certain financial situations require longer or indefinite retention periods for tax documents. For individuals, records related to property, such as purchase and sale documents, and those used to calculate depreciation, amortization, or gain or loss, should be kept until the assessment period expires for the year you dispose of the property. This helps determine the cost basis and accurately report any gain or loss when the asset is sold.

If you made non-deductible contributions to an Individual Retirement Arrangement (IRA), retain Form 8606, Nondeductible IRAs, indefinitely. This form documents your IRA basis, which helps calculate the tax-free portion of distributions in retirement. For those who have not filed a required tax return, tax authorities have an unlimited time to assess tax. Therefore, file all required returns, even if no tax is due, to establish a defined assessment period.

Employers must retain employment tax records for at least four years from the date the tax becomes due or is paid, whichever is later. This includes records like employer identification numbers, wage payment amounts and dates, reported tips, and copies of Forms W-4 and W-2. These records demonstrate compliance with payroll tax obligations and are subject to review by tax authorities.

Records to Retain Permanently

Beyond tax-specific retention periods, some documents hold permanent personal and financial significance. These include legal and identity documents such as birth certificates, marriage licenses, divorce decrees, and Social Security cards, which are necessary for various life events.

Other records to keep indefinitely involve significant assets and long-term financial planning. This includes deeds and titles for property, wills, and records of major home improvements, which help prove ownership and calculate cost basis for future sales. Retirement plan statements and investment purchase records should also be retained permanently. They document contributions, growth, and original investment costs, which helps determine taxable gains or losses upon sale or distribution.

Handling Records After Retention Periods

Once the recommended retention period for a tax document has passed, secure disposal is important to protect personal information. Simply discarding sensitive documents can expose individuals to identity theft and financial fraud. Shredding documents containing personal identifiers, account numbers, or financial details is a recommended method of physical disposal. Professional shredding services offer a secure option.

Transitioning to digital record-keeping offers a convenient and space-saving alternative to paper files. Digital records are easily organized, searched, and accessed, and are less vulnerable to physical damage or loss when properly backed up. When keeping digital copies, ensure they are stored securely with regular backups and strong password protection or encryption. Even with digital records, use secure deletion methods for sensitive files once their retention period ends.
