How long should a business keep tax records?

Maryland Business Compliance: Tax Record Retention

Maintaining proper tax records is essential for Maryland businesses to ensure compliance and facilitate smooth operations during audits or financial reviews.

Recommended Retention Period for Tax Records

• Federal and State Tax Returns: Keep copies of all filed tax returns for at least 7 years. This timeframe covers the IRS and Maryland Comptroller’s typical audit periods.
• Supporting Documents: Retain all related documents such as invoices, receipts, payroll records, and bank statements for a minimum of 7 years.
• Employment Tax Records: Maintain payroll tax records and employee tax forms for at least 4 years after the tax becomes due or is paid, whichever is later.

Operational Considerations

• Recordkeeping Systems: Use digital or physical filing systems to organize tax documents for easy retrieval during audits or tax filing seasons.
• Automation: Implement bookkeeping software that supports long-term storage and backup of tax records to reduce manual errors and loss risks.
• Compliance Updates: As of 2026, regularly review Maryland tax compliance requirements to adjust retention schedules if state or federal guidelines change.
• Disposal: Securely dispose of tax records after the retention period to protect sensitive business and employee information.
