In today’s globalized world, more businesses are operating in multiple states or countries. While this opens up opportunities to gain traction in more markets, it also creates complex tax implications.

Understanding two important tax terms—nexus and sales tax nexus—is necessary for expanding businesses that must comply with sales tax obligations. Failing to do so can result in significant financial penalties, and businesses that do not properly manage their sales tax obligations may face reputational injury or even legal action. Additionally, understanding sales tax nexus can help businesses determine where they are required to collect and remit sales tax, allowing them to accurately calculate the costs of doing business in different jurisdictions and remain compliant with tax laws.

We’ll cover what nexus and sales tax nexus are, including which activities can create sales tax nexus, different types of nexus, and how businesses can determine whether they have sales tax nexus in a particular jurisdiction. You’ll also learn best practices for helping your businesses manage sales tax obligations, stay compliant, and avoid potential penalties or legal action.

What is nexus tax?

Nexus tax, also known as “nexus fees” or “nexus surcharges,” is a type of tax or fee imposed by states or jurisdictions on businesses that have a sales tax nexus within their borders. A sales tax nexus is created when a business has a sufficient connection to or presence in a state or jurisdiction, such as a physical presence or economic activity, which triggers a sales tax collection obligation.

Nexus tax is calculated based on the specific rules and rates of the state or jurisdiction where the business has a sales tax nexus. Typically, nexus tax is a percentage of the total sales or revenue generated by the business within the state or jurisdiction. The exact percentage can vary widely depending on the state or jurisdiction, and some states may also levy additional fees or surcharges.

Examples of states where businesses with sales tax nexus are required to collect and remit state and local sales tax on taxable sales made within the state include:

• California
  California’s state sales tax rate is currently 7.25%, but local sales tax rates can vary from 0.1% to 2.5%, depending on the specific location.

• New York
  New York’s state sales tax rate is currently 4%, but local sales tax rates can vary from 3% to 4.875%, depending on the specific location.

• Texas
  Texas’s state sales tax rate is currently 6.25%, but local sales tax rates can vary from 0.5% to 2%, depending on the specific location.

Types of sales tax nexus

Sales tax nexus is the connection or relationship between a business and a state or jurisdiction that creates a sales tax obligation. There are different types of sales tax nexus that can trigger a requirement to collect and remit sales tax, including:

• Physical nexus
  Physical nexus is created when a business has a physical presence in a state or jurisdiction, such as a store, warehouse, or office. This type of nexus is the traditional standard for sales tax collection and has been established through various court cases. Examples of physical nexus include a business that has a physical location, employees, or inventory in a state.

• Economic nexus
  Economic nexus is created when a business has a certain level of economic activity in a state or jurisdiction, even if it does not have a physical presence there. Economic nexus laws typically set a threshold for sales, transactions, or revenue generated in a state; if that threshold is met or exceeded, the business is required to collect and remit sales tax. Many states have adopted economic nexus laws in recent years in response to the Supreme Court’s decision in South Dakota v. Wayfair, which mandated that businesses must collect and remit sales taxes on transactions in any state where they conduct more than 200 transactions or $100,000 worth of sales per year, even if they don’t have a physical presence in that state.

• Affiliate nexus
  Affiliate nexus is created when a business has a relationship with another business that has a physical presence in a state. This can happen when a business has an affiliate or subsidiary in a state that is related to the business, such as a common owner or branding. Affiliate nexus laws typically require the business to collect and remit sales tax if the affiliated business has a physical presence in the state.

• Click-through nexus
  Click-through nexus is created when a business has a relationship with a third-party seller or referral agent in a state. This can occur when a business pays a commission or referral fee to a third party for sales made through their website or marketing efforts. Click-through nexus laws typically require the business to collect and remit sales tax if the third party has a physical presence in the state.

Sales tax nexus

Sales tax nexus is a term used to describe the connection between a business and state or local government that triggers the requirement to collect and remit sales tax. It is the minimum threshold of activity that a business must have in a state before it is obligated to collect and remit sales tax in that state.

For instance, let’s say you run an online store that sells handmade candles. Your business is based in Arizona, but you also sell your candles in California, Texas, and New York. Each state has its own sales tax laws and rates, so you need to determine whether or not you qualify for sales tax nexus in those states.

In California, for example, you establish sales tax nexus if you have more than $500,000 in sales in the current or previous calendar year. As of April 25, 2019, California removed their previous threshold around the number of transactions. In Colorado, on the other hand, businesses that clear more than $100,000 in sales during any given year qualify for sales tax nexus.

Sales tax nexus can be created through various activities or factors, such as having a physical presence, economic activity, affiliate relationships, or click-through relationships in a state or jurisdiction. Once a sales tax nexus is established, the business is required to collect and remit sales tax on taxable sales made within the state or jurisdiction. The rules and requirements for sales tax nexus vary by state and jurisdiction, and it is important for businesses to understand their sales tax nexus obligations and comply with all applicable tax laws to avoid potential penalties or legal action.

Criteria for establishing sales tax nexus

There’s no universal set of criteria for establishing sales tax nexus, but generally several factors are considered when determining whether a business has a sales tax obligation in a particular state or jurisdiction. Some of the common criteria for establishing sales tax nexus include:

• Physical presence
  A physical presence can establish sales tax nexus in a state or jurisdiction. This can include having a physical office, store, warehouse, or other property in the state, or having employees or independent contractors working in the state.

• Economic activity
  Many states have adopted economic nexus laws, which create a sales tax obligation for businesses that meet certain thresholds for sales, transactions, or revenue generated in the state. These thresholds can vary widely by state and are subject to change. Here’s a full list of economic nexus standards for every US state.

• Affiliate relationships
  Some states have affiliate nexus laws, which create a sales tax obligation for businesses that have a relationship with an affiliate or subsidiary in the state. This can occur when a business has a common owner, branding, or other connection with an affiliate or subsidiary in the state.

• Click-through relationships
  Some states have click-through nexus laws, which create a sales tax obligation for businesses that have a relationship with a third-party seller or referral agent in the state. This can occur when a business pays a commission or referral fee to a third party for sales made through their website or marketing efforts.

Impact of sales tax nexus on businesses

The impact of sales tax nexus on businesses can be significant, depending on the specific circumstances and requirements of each state or jurisdiction. It’s important for businesses to know the states and jurisdictions where they have sales tax nexus and its impact, including:

• Compliance costs
  One of the most significant impacts of sales tax nexus on businesses is the cost of complying with state and local tax laws. Businesses that have a sales tax nexus in multiple states or jurisdictions may need to register for sales tax permits, collect and remit sales tax on taxable sales, file regular sales tax returns, and keep detailed records of sales and taxes collected.

• Penalties and interest
  Businesses that fail to comply with sales tax nexus requirements may face penalties and interest charges for late or incorrect filings or payments. These penalties can be substantial and can add up quickly, leading to additional costs and financial burdens for businesses.

• Competitive disadvantage
  Businesses that don’t properly manage their sales tax obligations may face a competitive disadvantage compared to businesses that are compliant with tax laws. Compliant businesses can accurately calculate the costs of doing business in different jurisdictions, while noncompliant businesses may struggle to compete on price or other factors.

• Reputational damage
  Failing to comply with sales tax nexus requirements can also lead to reputational damage for businesses. Customers may be less likely to do business with a company that has a history of tax compliance issues, and negative publicity or legal action can harm a business’s reputation and brand.

Steps businesses can take to comply with sales tax nexus laws

Complying with sales tax nexus laws can be a complex and challenging task for businesses, especially those that have a sales tax obligation in multiple states or jurisdictions. Here are some steps that businesses can take to comply with sales tax nexus laws:

• Determine where you have sales tax nexus
  The first step in complying with sales tax nexus laws is to determine where your business has a sales tax obligation. This can involve identifying where your business has a physical presence, economic activity, affiliate relationships, or click-through relationships, and understanding the sales tax nexus requirements of each state or jurisdiction where you have business activities.

• Register for sales tax permits
  Once you have determined where you have a sales tax obligation, you will need to register for sales tax permits in each state or jurisdiction where you have nexus. This typically involves filling out an application and providing information about your business, such as your federal tax ID number, business type, and contact information.

• Collect and remit sales tax
  After you have registered for sales tax permits, you will need to collect and remit sales tax on taxable sales made in each state or jurisdiction where you have nexus. This typically involves charging customers the appropriate sales tax rate, tracking sales and taxes collected, and filing regular sales tax returns and remitting sales tax payments to the state or jurisdiction.

• Keep detailed records
  It’s vital to keep detailed records of all sales and taxes collected to comply with sales tax nexus laws. This can include maintaining records of sales invoices, receipts, and other documentation that support your sales tax collections and remittances.

• Stay up to date on sales tax nexus requirements
  Sales tax nexus requirements can change frequently, and it’s important to stay up to date on sales tax laws and regulations in each state or jurisdiction where you have nexus. This can involve monitoring changes to sales tax rates, thresholds, and rules and working with a qualified tax professional to ensure compliance with all applicable tax laws.
