How to Collect Sales Tax Legally in Mississippi

Collecting sales tax correctly is essential for operating a business in Mississippi. Follow these steps to ensure compliance and smooth operations.

Register for a Sales Tax Permit

• Register with the Mississippi Department of Revenue (MDOR): Before collecting sales tax, obtain a sales tax permit by registering your business online through the MDOR website.
• Provide accurate business information: Include your business name, address, federal EIN, and type of business activity to complete registration.

Understand Taxable Sales and Rates

• Identify taxable goods and services: Most tangible personal property sales are taxable. Some services may also be taxable depending on state rules.
• Apply the correct sales tax rate: Mississippi’s state sales tax rate is 7%, but local county and city taxes may add to this. Use MDOR resources to determine the total rate applicable to your business location.

Collect and Record Sales Tax

• Include sales tax in customer transactions: Clearly separate the sales tax amount on receipts and invoices.
• Maintain accurate records: Keep detailed records of all sales, taxable amounts, and collected tax for bookkeeping and reporting purposes.

File Sales Tax Returns and Remit Payments

• File returns on time: Mississippi requires regular sales tax filings, typically monthly or quarterly depending on your sales volume.
• Use MDOR’s online filing system: Submit sales tax returns and payments electronically to ensure timely compliance.
• Keep copies of filings and payments: Maintain documentation to support your filings in case of audits.

Additional Operational Considerations

• Employee training: Train staff on how to apply sales tax correctly during transactions.
• Automation tools: Consider using point-of-sale systems that automatically calculate and apply the correct sales tax rates for Mississippi.
• Stay updated: As of 2026, regularly review Mississippi Department of Revenue updates to stay compliant with any changes in tax rates or rules.
