Operating in the U.S. as a Canadian Business

Navigating U.S. state and local tax laws can present several challenges due to the complexity and variability of regulations across different jurisdictions. Each state and locality has its own regulations, exemptions, and filing requirements. This diversity can make it difficult for businesses to ensure compliance, especially if they operate in multiple states across the country.

Canadian businesses can be subject to U.S. state and local tax sales & use tax laws under certain circumstances. If your business has a permanent establishment, which refers to a fixed place of business through which it carries out its activities, such as an office, branch, factory, or construction site, it may be subject to specific state and local tax sales & use tax laws. The same applies for businesses that generate certain types of income from U.S. sources even if the business does not have a permanent establishment in the U.S.

Whether you are a business owner or a finance professional, this comprehensive guide will provide you with valuable insights and practical tips to ensure compliance with U.S. state and local sales & use tax laws.

Understanding Nexus

The first step of determining a business’s state sales & use tax filing footprint is uncovering its Nexus status in each state. Physical and economic nexus are two key concepts used to determine whether a business has sufficient presence in a state to be subject to that state’s sales & use tax laws.

Physical Presence
Physical nexus refers to a tangible presence or connection that a business has in a state. This could include having a physical location such as an office, store, warehouse, or other facilities within the state.
Other factors that may establish physical nexus include having employees, agents, or independent contractors performing services in the state, owning or leasing property in the state, or regularly delivering goods into the state using company-owned vehicles.

Economic Presence
Economic nexus, on the other hand, is based on economic activity or sales volume rather than physical presence. It arises when a business conducts a certain level of economic activity within a state, even if it lacks a physical presence there.

Economic nexus thresholds vary by state and are typically based on the amount of sales revenue, transaction volume, or other measures of economic activity generated by the business within the state over a specified period (e.g., a calendar year). These laws have gained prominence in recent years, especially after the U.S. Supreme Court’s decision in South Dakota v. Wayfair, Inc. (2018), which allowed states to impose sales & use tax obligations on out-of-state sellers based solely on economic activity.
