Shock and Audit: Artificial Intelligence Meets State Taxation - David W. Bertoni, Tax Notes ($):

The [New York Department of Taxation and Finance] has not been alone among New York agencies in adopting AI for a variety of governmental functions. These agencies, however, may now face a reckoning because of New York’s LOADinG Act (shorthand for the Legislative Oversight of Automated Decision-Making in Government Act), which was signed into law by the governor on December 21, 2024.23 The LOADinG Act imposes a review and disclosure regime in connection with the adoption and continuing use of AI technologies in support of governmental functions — requirements consistent with voluntary federal guidance on the adoption of AI by industry.

 

NYC Under Fire For Shortage of Judges - Danielle Muoio Dunn, Bloomberg Tax ($): 

The New York City Tax Appeals Tribunal is facing criticism from tax practitioners because it doesn't currently have any administrative law judges to hear tax disputes, leading to a backlog of cases.

Minn. Lawmakers OK Tax Package, Data Center Change - Sanjay Talwani, Law360 ($):

Mississippi

Mississippi Issues Notice On Requirement of Third-Party Booking Entities To Collect and Remit Sales Tax - Nicholas Molinari, Eide Bailly LLP:

The Mississippi Legislature passed Senate Bill 2805, which clarifies the definition of the term "hotel" to include entities facilitating, arranging or brokering transient guest transactions, including third-party entities.

Third-party booking companies that meet the definition of "hotel" are required to collect Mississippi sales tax on the gross income of any hotel booking. A third-party booking company that registers and collects Mississippi sales taxes will relieve a property owner or hotel manager of the requirement to collect state and local sales taxes.

Tax Bites: Tips, Tricks and Opportunities in SALT

Colton Timberlake, Manager, Eide Bailly:

Sales Tax Exemption Certificates - A Must Have!

Have you ever sold a product or service to a customer who claims they are exempt from sales tax because they are a manufacturer, wholesaler, nonprofit, or another type of "exempt" entity? Proof of exemption is your best defense in a sales tax audit!

Collecting exemption certificates is an essential step for businesses to ensure that they are compliant with state sales and use tax laws. A properly completed exemption certificate serves as official documentation that a purchaser is exempt from paying sales tax on certain purchases. Without properly collected and maintained exemption certificates, businesses risk being held liable for uncollected taxes during an audit, which can lead to significant tax liabilities.

If you have questions about when, where, or what type of exemption certificates to collect, the SALT team can help develop a strategy to ensure that you remain compliant.
