How long should a business keep tax records?

North Dakota Business Tax Record Retention

In North Dakota, businesses should keep tax records for at least four years from the date the tax return was filed or the due date of the return, whichever is later. This retention period supports compliance with state and federal tax authorities during audits or reviews.

Key Operational Considerations

• Include all relevant documents: Maintain copies of tax returns, W-2s, 1099s, receipts, invoices, and payroll records.
• Payroll and Employment Records: Keep payroll tax records for at least four years to comply with North Dakota Workforce Safety and Insurance and IRS requirements.
• Electronic and Physical Storage: Ensure records are stored securely, whether digitally or physically, to protect sensitive information and facilitate easy retrieval.
• Recordkeeping Automation: Use accounting and recordkeeping software to streamline tax document management and ensure timely retention and disposal.
• Extended Retention Situations: If your business is involved in disputes, audits, or has unfiled returns, consider retaining records longer than four years.

As of 2026, following these guidelines will help maintain compliance with North Dakota tax authorities and support efficient business operations.
