Multistate tax liability: What’s your manufacturing business’s exposure?

As your manufacturing business expands into new markets, its state and local tax obligations become increasingly complex, spinning a web of different rules and obligations. Common business activities may produce a taxable connection, or "nexus," that exposes your organization to sales and use tax, state income tax, and other state tax obligations. Here's what you need to know to stay on the right side of the state tax authorities.

The long arm of state tax laws

Not so long ago, manufacturers didn't have to worry about tax liability in states where they lacked a physical presence, such as a plant or corporate offices. That changed in 2018, when the U.S. Supreme Court ruled in Wayfair, Inc. v. South Dakota that states can impose sales and use taxes on a business based solely on its "economic activity" within the state, regardless of whether the organization has offices or permanent employees there. As a result, many states began imposing such taxes on out-of-state businesses that exceed certain annual thresholds in revenue or number of transactions within their boundaries. (States are increasingly dropping the transactions threshold, focusing instead on revenue.)

The Wayfair ruling doesn't apply to income taxes. A federal law known as Public Law (P.L.) 86-272 has long protected certain out-of-state businesses from state net income taxes when their only in-state activities are the solicitation of orders for sales of tangible personal property — as long as the orders are sent out of state for approval and, if accepted, are fulfilled from outside the state.

But that protection has eroded in recent years. In 2021, the Multistate Tax Commission (MTC), in recognition of the dramatic increase in online business activities, issued a statement identifying certain activities as protected or unprotected under P.L. 86-272. The list of unprotected activities includes many potentially relevant to manufacturers, including:

  • Repair or maintenance activities on sold property,
  • Providing technical or service assistance,
  • Owning, leasing, using or maintaining a warehouse or inventory,
  • Installation,
  • Training,
  • Carrying samples for sale or distribution,
  • Collections and credit check activities, and
  • Having a remote employee in a state who performs work other than soliciting orders for tangible personal property (that employee could trigger state payroll tax obligations, too).

The MTC guidance also addresses certain activities conducted online. According to the MTC, for example, providing post-sale assistance to customers in a state through electronic chat or email, with the communication initiated by the customer clicking on an icon on your website, could subject you to income taxes in that state. Even using internet cookies could put you outside the protection of P.L. 86-272 under the MTC's model.

If your manufacturing business has nexus with a state for purposes of sales and use tax, income tax, or other types of taxes, you could be subject to tax obligations such as registering with the state tax authority and reporting, collecting and remitting taxes. Keeping up with those obligations is no small task.

Note: Currently, California, New York, New Jersey and Massachusetts have adopted the MTC's guidance to some degree; adoption across other states varies.

Compliance steps

Adoption of the MTC guidance isn't the only matter where states have taken different stances toward the taxation of out-of-state businesses. If you think your manufacturing business may have nexus with a state, you need to know its rules and requirements regarding, among other things, the nexus standards, sourcing of sales, apportioning of income and the availability of exemptions.

You also must implement the necessary controls to ensure you don't overlook "economic activities" that could subject you to taxation. For instance, how will your tax team know if an employee crosses state lines to perform an installation, make a service call or train a customer on how to use your product?

And you should take potential state tax liability into account when developing plans to grow your business. Increased revenue, inventory storage, leasing or deliveries into a state could mean tax obligations that you want to know about in advance so you can properly prepare.

Act now

States are increasingly using data and analytical tools to identify out-of-state businesses that may have filing or tax obligations within their jurisdiction. We can help you evaluate your business's multistate tax exposure so you can uncover compliance gaps, avoid costly assessments and penalties, and take advantage of all applicable tax credits and other incentives.
