What to keep, how long to keep it, and whether digital copies are enough

THE PRACTICAL RULE: Keep records long enough to support every item reported on a return, plus any records that establish the basis of property you still own. A simple “three-year rule” is not enough for every situation.

Why record retention matters

Good recordkeeping supports the income, expenses, deductions, and credits reported on a tax return. It also helps a business monitor performance, prepare financial statements, obtain financing, respond to an IRS notice, support an insurance claim, and determine the basis of business property.

The IRS does not impose one universal retention period on every document. The correct period depends on what the record proves and the period of limitations that applies to the return. In addition, state agencies, lenders, insurers, licensing authorities, and attorneys may require records to be kept longer.

The basic IRS retention periods

Retention period	When it generally applies
3 years	Most correctly filed income tax returns when no special rule applies.
3 years / 2 years	For a refund claim, keep records for three years from filing the original return or two years from paying the tax, whichever is later.
4 years	Employment tax records, measured from the later of when the tax became due or was paid.
6 years	When more than 25% of gross income that should have been reported was omitted.
7 years	When claiming a deduction for a bad debt or a loss from worthless securities.
Indefinitely	When no return was filed or a fraudulent return was filed.
Ownership period + limitation period after sale	Rental real estate and other property records. Keep the purchase closing statement and related acquisition records for the entire time the property is owned. Also retain improvement records, depreciation schedules, and the closing statement and selling-expense records from the sale until the period of limitations expires for the return reporting the sale or other disposition.

These are federal minimums. A conservative business policy often keeps ordinary tax records for seven years and permanent records indefinitely, while retaining asset records throughout ownership and beyond the year of disposal.

What records should a business keep?

A business may use any recordkeeping system that clearly shows income and expenses. The system should summarize transactions in accounting records and preserve the supporting documents behind those entries.

Income and deposit records

• Customer invoices, sales reports, receipt books, and cash-register records.
• Merchant processor reports, Forms 1099, and online marketplace reports.
• Bank deposit records and documentation explaining transfers, loans, owner contributions, or other nontaxable deposits.

Unexplained deposits can become a problem during an examination. Records should identify both the amount and the source of money entering a business account.

Expenses and purchases

Expense documentation should establish the payee, amount, date, proof of payment, what was purchased, and the business purpose. Supporting documents may include invoices, receipts, canceled checks, bank statements, credit-card statements, contracts, and electronic payment confirmations.

Important: A bank or credit-card statement proves that a payment occurred, but it may not prove what was purchased or why it was business-related. More than one document may be needed.

Payroll and employment taxes

Employers generally must keep employment tax records for at least four years. Records commonly include Forms W-4, payroll registers, time records, wage and benefit information, payroll tax deposits, Forms 941 and 940, Forms W-2 and W-3, state payroll filings, and worker-classification documentation.

Travel, meals, vehicles, and gifts

These expenses may require more than a receipt. The records may need to establish the amount, date, location, mileage, attendees, and business purpose. A contemporaneous mileage log, calendar entry, travel itinerary, or written note can supply information that does not appear on the receipt.

Business property and other long-term records

Keep records for equipment, vehicles, buildings, improvements, rental real estate, and other assets for the entire ownership period and until the limitation period expires for the tax return reporting the sale or other disposition. For rental property, retain the purchase contract and closing statement from acquisition, records of capital improvements, depreciation schedules, refinancing documents that affect basis, and the closing statement and selling-expense records from the eventual sale. These documents are needed to establish original and adjusted basis, depreciation, and the gain or loss on disposition.

• Purchase contracts, invoices, and closing statements.
• Installation, delivery, and improvement costs.
• Depreciation schedules and Section 179 records.
• Sale documents, including the final closing statement, commissions, legal fees, and other selling expenses.

Record-retention rules for individuals

Individuals generally follow the same limitation periods. Most should keep filed returns and supporting records for at least three years, with longer retention when a special rule applies.

Common individual records

• Forms W-2 and 1099, brokerage statements, and retirement distribution forms.
• Mortgage interest, charitable contribution, medical, education, and childcare records.
• Health-insurance forms, estimated-tax payment confirmations, and documents supporting tax credits.
• Bank statements, canceled checks, and other proof of payment when needed to substantiate an item.

Homes, investments, and other property

Property records should be kept for as long as the property is owned and through the applicable period of limitations after it is sold or otherwise disposed of. For a residence or rental property, retain the purchase closing statement, purchase contract, and records of capital improvements. For rental property, also retain depreciation schedules and other basis adjustments. When the property is sold, keep the sale closing statement, commissions, legal fees, and other selling-cost records with the return reporting the sale.

Best practice: Keep copies of filed federal and state income-tax returns permanently. They provide a history of income, elections, carryovers, basis information, and prior transactions that may be needed years later.

Are digital images of receipts acceptable?

Electronic records are generally acceptable when they remain accurate, complete, legible, accessible, and capable of being reproduced. The same fundamental recordkeeping requirements that apply to paper records also apply to electronic records.

A clear PDF or photograph can be more useful than a thermal-paper receipt that fades. However, simply taking a picture is not a complete recordkeeping system. The image must be stored so that it can be located, matched to the transaction, and produced years later.

Use meaningful file names

A file called “IMG_7834.jpg” is difficult to identify. A more useful name is:

Example: 2026-07-18_OfficeDepot_146.72_PrinterSupplies.pdf

The file name immediately identifies the date, vendor, amount, and purpose. The document can then be stored in the appropriate annual expense folder or attached directly to the accounting transaction.

When should the original paper be kept?

A digital copy is usually practical for ordinary receipts, but businesses may still choose to retain originals of signed contracts, deeds, titles, closing documents, loan agreements, legal documents, or items for which authenticity could later matter. Paper and digital systems can be combined, provided the business has a consistent policy and knows where each category is stored.

Building a practical recordkeeping system

A useful system does not need to be complicated. It does need to be consistent, secure, and regularly maintained.

A simple annual folder structure

Suggested folders: Bank and credit cards; income; expenses; payroll; assets and vehicles; tax filings; and legal or permanent records. Organize each folder by tax year and use consistent file names.

Practical habits that make the system work

• Scan receipts promptly and record the business purpose at the time of the transaction.
• Upload documents regularly instead of waiting until tax season.
• Export accounting and payroll data before changing providers.
• Maintain secure backups in more than one location and test that they can be restored.

Before destroying records

Do not destroy records merely because a return is three years old. First determine whether an audit, amended return, refund claim, collection matter, lawsuit, insurance matter, carryover, or asset-basis issue remains open. State law or a contractual obligation may also require a longer period.

When records are no longer needed, destroy them securely. Cross-cut shred paper containing Social Security numbers, bank information, payroll data, or other confidential information. Electronic files should be securely deleted rather than simply moved to a recycle bin.

A sensible small-business policy

Suggested approach: Keep ordinary tax records for at least seven years, employment and payroll records for at least seven years, permanent records indefinitely, and property records for the entire period of ownership plus the applicable limitation period after disposal.

Good recordkeeping creates a reliable trail from the original transaction to the accounting records and ultimately to the tax return.
