Yes. As of July 1, 2023, software as a service (SaaS) is taxable at the state sales tax rate of 7% if the software is maintained on a server physically located in the state and if the SaaS provider has nexus in Mississippi.

Understanding the specific rules that govern taxation in Mississippi is key to sales tax compliance. This article will explain how to ensure your business avoids errors that could lead to fines or other penalties.
According to Mississippi’s Senate Bill 2449, SaaS may be taxed as a computer software service, if it is used or accessed within the state (hosted), at the state’s standard 7% sales tax rate. This taxation applies to both business-to-business (B2B) and business-to-consumer (B2C) transactions. These rules, which went into effect on July 1, 2023, were implemented as a way to address gaps in previous tax laws on the subject of SaaS taxability.
For the transaction to be taxable, the software must be hosted on a server in Mississippi. The sale would be nontaxable if the software is hosted outside of Mississippi, for example, in the cloud and accessed over the internet.
However, while the legislation clarifies which SaaS transactions are taxable, it does not automatically require a provider to collect and remit sales tax. This obligation depends on whether the provider has established nexus in Mississippi.
The term “nexus” refers to a physical or economic presence in a state. If a provider meets one of Mississippi’s nexus thresholds, it must collect and remit sales tax there. There are two types of nexus: physical and economic:
Understanding where your business has nexus is a necessary step in staying compliant. However, even if you have nexus in Mississippi, certain SaaS transactions may qualify for exemptions. Whether or not a transaction is exempt can depend on how the SaaS is delivered or used.
Certain exemptions and exclusions can apply to SaaS transactions in Mississippi, depending on how the service is used, delivered, or transferred. For example, transfers of SaaS between affiliated entities, such as a parent company and its subsidiary, are treated as nontaxable transactions. Proper documentation is typically required to substantiate the transfer's relationship and nature.
In addition, some nonprofit or academic organizations could qualify for exemptions or reduced tax rates under certain conditions.
Providers should verify whether a specific exemption applies to their business by talking to a tax professional or an official representative of the Mississippi Department of Revenue.
Digital goods are typically subject to Mississippi’s standard 7% sales tax rate. As outlined in Senate Bill 2449, this includes goods delivered electronically, such as:
Because digital goods are classified similarly to tangible personal property for tax purposes, they are taxable when sold, rented, or accessed by consumers within the state.
According to the Mississippi Department of Revenue, most local jurisdictions do not charge an additional local sales tax rate in the state. This means that Mississippi’s 7% sales tax rate is used in most cities and counties in the state. However, in Jackson and Tupelo, there are additional taxes of 1% and 0.25%, respectively.
For example, if a customer in Hattiesburg, Mississippi, is charged $3,000 for an annual software subscription hosted on a server in Mississippi, the applicable tax rate is 7%. That would mean the SaaS provider would have to collect $210 in taxes, bringing the total cost to the customer up to $3,210.
While this consistent tax rate may make it easier for SaaS providers doing business in most cities in Mississippi, numerous other aspects of compliance need to be managed. These include determining nexus, proper tax collection, and timely filing of sales tax returns.
Staying compliant with Mississippi’s tax rules involves following several clear steps, including:
SaaS companies should also account for other important aspects of compliance, such as utilizing voluntary disclosure agreements (VDAs) to resolve unpaid or uncollected taxes and deregistering if they no longer meet nexus requirements.
Failure to comply can lead to a range of negative outcomes, including interest charges, penalties, and a higher likelihood of being audited. To simplify these processes and maintain compliance, businesses may benefit from using platforms like Numeral or accessing resources offered by the Mississippi state government.

Although they used to be less clear, Mississippi’s tax regulations for SaaS have recently been clarified by Senate Bill 2449, which suggests that SaaS physically used or delivered within the state may be subject to a 7% sales tax rate. However, exemptions may apply to some sales, such as if the software is hosted in another state.
Digital goods, including e-books, software downloads, music, and movies, are also taxable under these updated rules.
For SaaS providers in Mississippi, compliance involves several steps: determining nexus, registering for a Sales and Use Tax account, accurately calculating tax rates, collecting taxes during transactions, and filing and remitting returns through the Mississippi Department of Revenue’s TAP portal.
Providers will also need to consider other aspects of compliance, such as deregistration if they no longer have nexus within the state. Platforms like Numeral and resources provided by the Mississippi Department of Revenue may be beneficial to simplify the compliance process and reduce the risk of penalties, audits, and other challenges.
