Types of Documents to Retain
Maintaining comprehensive records provides a clear picture of your business's financial health and supports various legal and tax obligations.
Key documents to retain include:
💲 Financial Records
The most important category (IMHO) is your business’s financial records.
Banking Records:
Periodic statements from your bank, loan documentation, and significant transactional events (like a large wire transfer or deposit over $10,000) are important to keep as part of your overall business banking history. Keep these to help with getting loans and in the event of an audit or other inquiry about your transaction history.
Retention Period: at least seven years
Income Statements:
Also known as profit and loss statements, these documents summarize your business's revenues, expenses, and profits or losses over a specific period. They provide insights into operational efficiency and profitability.
Retention Period: permanently
Balance Sheets:
These statements offer a snapshot of your business's financial position at a given point in time, detailing assets, liabilities, and shareholders' equity. Balance sheets are crucial for assessing financial health and making informed business decisions.
Retention Period: permanently
Cash Flow Statements:
These reports track the flow of cash in and out of your business, highlighting operating, investing, and financing activities. They are essential for managing liquidity and ensuring the business can meet its financial obligations.
Retention Period: permanently
General Ledgers:
The central repository of your business's financial transactions, general ledgers provide a comprehensive record of all financial activities, supporting the creation of other financial statements.
Retention Period: permanently
Purchase Records:
This type of documentation is for assets and inventory acquired by the business, including purchase orders, bills of sale, and receipts. These records are essential for tracking asset depreciation, calculating the cost of goods sold, and supporting tax deductions.
Retention Period: at least seven years after the asset is sold or retired (i.e.: disposed of)

Including electronic funds transfers, credit card transactions, and other digital payment methods. these are important for verifying income and expenses.
Retention Period: at least seven years
Depreciation Schedules:
Detailed records of asset depreciation, including the original purchase price, date of acquisition, and depreciation method used are necessary for tax purposes.
Retention Period: at least seven years after the asset is sold or retired (i.e.: disposed of)
Cancelled Checks:
Cancelled checks that have been processed and cleared by the bank, and serve as proof of payment for various expenses. It's advisable to retain cancelled checks that are related to tax payments and significant purchases.
Retention Period: at least seven years
Petty Cash Vouchers:
Some businesses maintain a “Petty Cash” account for small purchases to simplify reimbursement. Recording small cash expenditures made by the business and keeping vouchers can help with tracking minor expenses.
Retention Period: at least two years

Purchase Orders:
Purchase orders are used to authorize the purchase of goods or services. Retain these records to verify orders and resolve potential disputes.

Lease Payment Records:
Keep track of payments made under leasing agreements for property or equipment, and retain these records to verify payments and terms.

Save any documentation that substantiates entries in your books, such as sales slips, paid bills, invoices, receipts, and deposit slips. These are crucial for verifying income and expenses reported on tax returns.

💸 Tax Documents
When you are self-employed, your tax filing paperwork becomes a bit more complex than if you are just an employee.
Save these types of tax documents to ensure that you are prepared for an audit or other tax-related inquiry:
Filed Tax Returns:
These are official documents submitted to tax authorities, detailing your business's income, expenses, and other pertinent financial information for a specific tax year. They serve as a formal declaration of your business's tax obligations.
Filed tax returns are crucial for calculating tax liabilities, securing financing, and providing proof of compliance during audits or legal inquiries.
Retention Period: permanently
Supporting Documents for Tax Returns:
Records that substantiate the entries made on your tax returns are important to retain as part of your overall tax filing history, including (note: some of these were mentioned with more detail, above):
Income Records: Invoices, sales receipts, and bank statements that verify revenue.
Expense Documentation: Receipts, bills, and cancelled checks for deductible expenses.
Asset Records: Purchase agreements and depreciation schedules for property and equipment.
Payroll Records: Employee wages, tax withholding, and benefits documentation.
These documents provide evidence to support the accuracy of your tax returns, especially during audits or disputes.
Retention Period: at least three years after the tax return filing date (but seven years after filing is recommended)
Correspondence with Tax Authorities:
This includes all communications between your business and tax authorities, such as:
Notices and Letters: Documents regarding tax assessments, refunds, or changes to tax laws.
Audit Reports: Findings and conclusions from tax audits.
Rulings and Determinations: Official decisions on specific tax matters affecting your business.
Maintaining these records helps track your interactions with tax authorities, ensuring compliance and providing a reference in case of future inquiries or disputes.
Retention Period: at least seven years (issues or disputes may arise long after the original communication)
💼 Payroll, Employee, and Vendor Records
Keep organized and comprehensive records related to employee or staff payroll, employee records, and documents related to your vendor relationships or transactions. These records will protect against potential disputes.
Payroll Records:
Save all personal and employment details, including full name, Social Security number, address, date of birth, occupation, and employment dates.
Retention Period: at least three years.
Timekeeping Records:
It is important to save records created by your staff tracking their hours worked each day and total hours each workweek. These are typically retained in the form of time cards or electronic logs.

Accident Reports and Claims:
Workplace accidents and related insurance claims sometimes happen. These records are important for legal and insurance purposes.

💡 Tip: while some state laws allow for the destruction of certain reports and claim records after three years, it's advisable to retain records longer if they pertain to incidents that could result in legal action beyond the standard limitation periods. Better to keep these records… just in case!
⚖️ Legal Documents
Maintaining organized and comprehensive legal documents is essential for small business owners to ensure compliance, protect intellectual property, and facilitate smooth operations.
Business Formation Papers:
These documents establish the legal structure of your business and may include articles of incorporation, bylaws, partnership agreements, and operating agreements. As I have shared in earlier posts, this is how you define ownership, management structures, and operational guidelines, serving as a foundation for your business's legal identity.
Retention period: permanently (for ongoing legal and operational reference)
Licenses and Permits:
These official documents are issued by governmental agencies authorizing your business to operate in specific industries or locations. These ensure compliance with local, state, and federal regulations to operate legally.
Retention periods: Keep current licenses and permits until expiration. Retain expired documents for at least three years after expiration to address any potential regulatory inquiries.
Contracts:
Contracts are legally binding agreements between your business and other parties, including clients, vendors, employees, and partners. These define the terms and conditions of business relationships, outlining the rights and obligations of each party.
Retention period: Maintain contracts for at least seven years after their termination or expiration to safeguard against potential legal disputes.
Intellectual Property Documents:
Also referred to as “I.P.”, these records are related to creations of the mind, such as inventions, literary and artistic works, designs, symbols, names, and images used in commerce. I.P. includes patents, trademarks, copyrights, and trade secrets documentation. Protect your business's intangible assets, maintain ownership of exclusive rights, and prevent unauthorized use by others.
Retention period: Retain these documents permanently, as they are critical to maintaining and defending your intellectual property rights.

Due Diligence
Do your due diligence when you are setting up a record-keeping system, and to ensure that you are NOT destroying important records that need to kept longer.
I am an entrepreneur - not a tax professional or a CPA - so please keep in mind that your unique circumstances may be different from what I have captured here.
This is an incomplete list, and there may be other types of records that are unique to your business sector or record-keeping needs.
When uncertain or confused, it is best to consult an accountant or tax advisor to help you.
