Mississippi Sales Tax and Invoicing Rules for 2026

TL;DR: Mississippi has a 7% state sales tax -- one of the highest in the nation -- with no general local add-ons. Remote sellers exceeding $250,000 in sales must collect. Most goods and many services are taxable, and invoices must clearly separate tax from the sale price.

Mississippi's 7% rate and broad tax base -- including groceries and many services -- make it one of the most aggressive sales tax states. Its economic nexus threshold is also notably higher than most states at $250,000. This guide covers Mississippi's rates, nexus rules, invoice requirements, exemptions, filing deadlines, and penalties for 2026.

State sales tax rate

Mississippi levies a 7% statewide sales tax, which is among the highest state-level rates in the country. Mississippi generally does not allow local jurisdictions to add their own general sales taxes, so the 7% rate applies uniformly across the state for most transactions. A few special-purpose tourism and economic development taxes exist in limited areas but do not apply to general retail sales. Certain categories enjoy reduced rates: farm equipment and manufacturing machinery are taxed at 1.5%, and motor vehicles are subject to a separate 5% rate.

The uniformity of the rate statewide simplifies compliance but the high rate itself makes Mississippi one of the more expensive states for consumers purchasing taxable goods.

Nexus rules

Physical nexus is established through maintaining a store, warehouse, office, employees, inventory, or property in Mississippi. Having agents or representatives soliciting orders in the state also triggers nexus.

Economic nexus in Mississippi is triggered at a $250,000 gross revenue threshold from sales into the state. There is no separate transaction count threshold. This is notably higher than the $100,000 threshold used by most states, meaning smaller remote sellers may not need to collect Mississippi tax. Marketplace facilitators are required to collect and remit sales tax on behalf of third-party sellers once the facilitator meets the threshold.

What must appear on invoices

The Mississippi Department of Revenue expects sales invoices to include:

• Seller's name, address, and Mississippi sales tax permit number
• Buyer's name and address
• Date of sale
• Description of goods or services
• Sale price of each item or service
• Sales tax charged as a separate line item
• Tax rate applied (7%, 1.5%, or 5% depending on the product category)
• Total amount including tax
• Exemption documentation for non-taxable sales

Mississippi law permits sellers to absorb sales tax rather than separately stating it, but this is uncommon and the seller remains liable for the full tax amount regardless. Keeping clear records with separately stated tax is strongly recommended for audit purposes.

Exemptions and special cases

Mississippi exempts the following:

• Prescription drugs and certain medical devices
• Unprepared food purchased with SNAP benefits (food purchased with cash is taxable at 7%)
• Sales to federal and state government entities
• Agricultural machinery and equipment (taxed at a reduced 1.5% rate instead of exempt)
• Manufacturing machinery (taxed at a reduced 1.5% rate)
• Motor vehicles (taxed at a separate 5% rate instead of 7%)
• Sales to qualifying churches and nonprofit hospitals
• Custom software developed for a single customer

Groceries are fully taxable at 7% in Mississippi, making it one of the few states taxing groceries at the full rate with no reduced rate or credit. Clothing is taxable. Mississippi taxes many services including repair, cleaning, installation, and telecommunications services. Digital products and SaaS are generally taxable when accessed by Mississippi customers.

Filing frequency and deadlines

Mississippi requires electronic filing through the TAP (Taxpayer Access Point) system. A 2% vendor discount (capped at $50 per month) is available for timely filers. Returns are required even for zero-liability periods.

Penalties for non-compliance

A penalty of 10% of the tax due is assessed for late payment. Interest accrues at 1% per month on unpaid balances. Failure to file a return incurs an additional $25 per return penalty. The Department of Revenue may revoke sales tax permits for persistent non-compliance and may pursue criminal penalties for willful evasion. Responsible officers of a corporation can be held personally liable for uncollected or unremitted taxes.
