New nexus: Funding the cost of expanding into new states

Key takeaways

  • New nexus may bring costs beyond the sales tax you collect.

  • Expanding into multiple states could mean several new costs at once.

  • Advanced planning helps you prepare for the potential cash-flow impact.

  • Working capital may help bridge gaps when growth outpaces available cash.

Expanding into a new state is an exciting step for a growing business. It can also bring new sales tax obligations that aren’t always easy to anticipate.

 

As you reach more customers, you may establish sales tax nexus in states where you previously had no obligations. When expansion happens quickly, those obligations can arise in several states at once, adding new costs and cash-flow considerations.

 

A little planning can make those costs easier to anticipate and manage. Here’s what finance teams should consider as they plan for growth.

Why new nexus has a financial impact

Sales tax nexus is the connection between a business and a state that creates an obligation to collect and remit sales tax. One common way businesses establish nexus is through economic activity in a state.

 

The tricky part is that nexus tax rules vary by state. According to the Tax Foundation, 45 states levy a state-level sales tax, while 38 states also allow local sales taxes.

 

States can also use different sales thresholds and measurement periods to determine when a business needs to register and start collecting tax. If you’re growing quickly, you may find yourself approaching several thresholds in quick succession.

 

For finance teams, that makes nexus part of the financial planning conversation, not just a tax or compliance issue.

 

Avalara’s state-by-state guide to economic nexus laws can help you understand how requirements differ across states.

What does new nexus actually cost?

At first, sales tax can seem fairly straightforward. You collect the tax from the customer and send it to the appropriate state or local tax authority.

 

In reality, several costs can come with establishing nexus.

 

Registration and setup

 

Once you’ve determined that you have nexus in a state, you’ll generally need to register to collect sales tax there.

 

Some states don’t charge a fee for a sales tax permit, but requirements and costs vary. There’s also the internal work to consider. Someone needs to gather the necessary information, complete the registration, configure your tax systems, and make sure your processes are ready.

 

If you’re entering several states at once, that work can add up quickly.

 

Catching up on past tax liabilities

 

This is where an unexpected financial issue can arise.

 

A business may discover it crossed a state’s nexus threshold before realizing it needed to register and start collecting sales tax. If so, it may need to address sales tax that should have been collected on past sales.

 

Depending on the circumstances and the state, that can include interest or penalties in addition to the tax itself.

 

There’s another important consideration: You may not always be able to go back to customers and collect the tax after the sale. In that situation, the business may need to absorb some or all of the liability.

 

That’s why monitoring nexus before you cross a threshold can be valuable. It gives you more time to understand what’s coming and plan for it.

 

Ongoing administration

 

Nexus isn’t a one-and-done expense, either.

 

After registering, your business may need to calculate and collect the right amount of tax, file returns, make payments, maintain records, and continue monitoring its obligations.

 

As you enter more states, those responsibilities can grow with you. With sales taxes accounting for about 24% of combined state and local tax collections, these obligations represent a significant part of the broader tax landscape.

Why new nexus can become a cash-flow event

For a growing business, the biggest challenge may not be the total cost. It may be when the cost arrives.

 

Think about everything else competing for cash during an expansion: inventory, new hires, marketing, technology, equipment, and other operating expenses. Nexus-related costs can fall in the middle of it all.

 

There’s also a timing issue: You might incur the costs of expanding into a new market before you’ve collected enough revenue from that market to cover the costs comfortably. If several states trigger nexus tax around the same time, the gap can become larger.

 

And if you discover an obligation after the fact? You could be dealing with a cost you didn’t plan for at all.

 

None of this means you should slow down growth. It simply means that sales tax obligations deserve a place in the financial plan alongside the other costs of expansion.

How to plan for and fund nexus-related growth costs

You don’t need to predict every future tax expense perfectly. Advanced planning can go a long way.

 

Start by:

 

  1. Watching your state thresholds. Keep track of where sales are approaching economic nexus thresholds so you have time to prepare.

  2. Estimating the costs. Consider registration, system setup, internal labor, remediation, and ongoing compliance.

  3. Planning for multiple states. Don’t look at each state in isolation. Consider what happens if you trigger nexus in several states within a short period.

  4. Adding nexus to your cash-flow forecast. Include potential tax and compliance costs alongside other expansion expenses.

  5. Leaving room for surprises. If you’re growing quickly, give yourself some flexibility for obligations you may not have anticipated.

 

Avalara’s sales tax risk assessment can also help you identify potential nexus exposure and understand where you may have obligations.

 

If you have a healthy growth plan but need to cover expansion-related expenses before the resulting revenue arrives, a cash reserve or working capital solution can help bridge that timing difference.

 

The important thing is to look at the need in context. How much cash do you need? When will you need it? And how does that need fit into the broader expansion plan?

 

Nexus is one piece of the picture, not the whole picture.

Plan for nexus before it becomes a surprise

Triggering economic nexus can be a sign of healthy growth into new markets. The key is making sure the financial impact doesn’t catch you off guard.

 

When growth creates a cash gap, Avalara Capital can provide working capital to help keep your business moving forward.

FAQ

It depends on the state. Some states don’t charge a fee for a sales tax permit, while others may have registration or related business fees. You’ll also want to account for the time and resources your team needs to complete registration and set up your tax processes.

Yes. If your business established nexus and was required to collect sales tax but didn’t, you may be liable for the tax that should have been collected. Depending on the circumstances and the state, interest and penalties may also apply.

Potential costs include registration, tax system setup, internal administrative work, ongoing filing and remittance, and remediation if you discover that you should have been collecting tax earlier.

Monitor sales against state-specific thresholds, estimate potential nexus-related costs, and include them in your expansion and cash-flow forecasts. It’s also helpful to model what happens if several states trigger nexus within a short period.
