From Road Trips to Clicks: How Cross-Border Shopping Has Evolved

If you’ve ever driven across state lines to save a few hundred dollars on a major purchase, you’re not alone.

For decades, this kind of behavior—known as cross-border shopping or consumer hopping—has played a quiet but powerful role in how consumers make decisions and how states design tax policy. At its core, it’s exactly what it sounds like: people leaving high-tax areas to buy goods in places where the tax bill is lighter, or even nonexistent.

It’s also one of the clearest examples of tax evasion vs tax avoidance—and yes, the distinction matters.

But there’s a modern twist to this story. While cross-border shopping used to be a major concern for states, the landscape has shifted dramatically over the past couple of decades. Mostly thanks to the rise of e-commerce and the landmark South Dakota v. Wayfair decision, how, where, and even why people shop has evolved.

So what does cross border shopping look like today? And more importantly, what does it mean for businesses trying to stay compliant in an increasingly complex sales tax environment?

Let’s take a closer look.

Key Takeaways

• Consumers cross-border shop when sales tax savings outweigh travel costs and time
• Today, destination-based sourcing rules limit online tax avoidance opportunities
• States like Delaware and New Hampshire still attract in-person cross-border shoppers
• Sales tax holidays create short-term purchasing shifts—but don’t greatly increase consumer hopping
• For businesses, the real takeaway is this: consumer behavior has shifted, but tax complexity has increased

What Is Cross-Border Shopping?

Cross-border shopping occurs when consumers travel to a different jurisdiction (city, county, or state) to reduce or eliminate sales tax on purchases.

Sometimes it’s a family loading up the car to buy a $2,000 couch in a neighboring state. Other times, it’s a business owner sourcing equipment where the tax treatment is more favorable. Either way, the logic is straightforward: if the savings are meaningful enough, it might be worth the trip.

That said, most purchases don’t make the cut. People rarely want to burn a tank of gas to save a couple of dollars on groceries. But when you’re looking at a 5-10% difference on a high-ticket item, the math starts to make sense.

Economists have long understood that consumers respond strongly to tax differentials, especially when the benefit outweighs the total “cost” of getting there, (like time, fuel, and effort).

Still, modern consumer attitudes have shifted, and convenience has become king. Most shoppers today are less willing to go out of their way unless the savings are substantial.

Tax Avoidance vs Tax Evasion: Why the Difference Matters

From a compliance standpoint, cross-border shopping falls under tax avoidance, not tax evasion. What’s the difference?

• Tax avoidance means structuring purchases to legally reduce tax burden—like buying in a lower-tax state or timing purchases during a sales tax holiday
• Tax evasion, on the other hand, involves illegally failing to pay taxes owed

Here’s where things get a little gray. Technically, if you purchase something out of state and don’t pay sales tax, you may owe use tax in your home state. In reality, very few consumers report and pay it.

That gap between theory and practice is part of what made cross border shopping such a persistent issue historically. But as you’ll see, that’s begun to change.

Classic Examples: Where Cross-Border Shopping Thrives

Delaware

Delaware is the gold standard example of when having no sales tax can attract more business.

With no state or local sales tax and bordering high-tax states like Pennsylvania and New Jersey, the state has long marketed itself as a retail haven. For years, travelers were greeted with signs proudly declaring it the “Home of Tax-Free Shopping.” These days, the slogan is a bit more subtle—but the tax advantage remains.

Delaware naturally attracts shoppers looking to save on big purchases like furniture, electronics, and luxury goods.

This behavior hasn’t gone unnoticed by Delaware’s neighbors, either. In fact, parts of New Jersey—like Salem County—have responded by offering reduced sales tax rates in bordering locations, specifically for business purchases. That’s tax competition in action.

New Hampshire

A similar dynamic plays out in New England. New Hampshire, which has no general sales tax, consistently pulls retail activity away from nearby Vermont, where rates hover around 6%.

One study claims that sales per capita in New Hampshire have tripled since the late 1950s, while sales in border counties in Vermont have largely stayed the same. Over time, retail businesses themselves have gravitated toward the tax-free side of the border, clustering where demand naturally flows and sales tax compliance is less complex.

Chicago vs. the Suburbs

Cross-border shopping doesn’t just happen across state lines.

Chicago has one of the highest combined sales tax rates in the nation, exceeding 10%. As a result, consumers sometimes head to nearby suburbs like Naperville and Wheaton to make major purchases at lower rates. It’s the same state and the same product, but a largely different tax bill.

The Turning Point: How E-Commerce Changed Everything

For a long time, cross-border shopping didn’t even require crossing a border.

Before 2018, online shopping functioned as a kind of digital tax avoidance strategy. Many online retailers weren’t required to collect sales tax unless they had a physical presence in the buyer’s state. That meant consumers could avoid tax on every purchase, no matter where they were located or where the item came from.

As you can probably imagine, states weren’t thrilled about that.

The loss in revenue was significant, and local businesses—who had to collect sales tax—were at a clear disadvantage. That tension ultimately led to the South Dakota v. Wayfair decision, which fundamentally changed how sales tax works in the United States.

Today, most states operate under destination-based sourcing rules, meaning sales tax is applied based on where the customer receives the product, not where the seller is located. The result is that consumers can no longer easily “shop around” for lower tax rates online.

In many ways, this marked the end of cross-border shopping’s most impactful era.

Sales Tax Holidays: A Short-Term Twist

There is, however, one interesting exception to the rule: sales tax holidays.

A sales tax holiday is a temporary period—usually a weekend—when certain items are exempt from sales tax. As of 2026, around 19 states offer them, typically covering things like clothing, school supplies, computers, and emergency preparedness items.

At first glance, these holidays might seem like they would encourage cross-border shopping. After all, what parent doesn’t need to save a few bucks on new clothes, backpacks, and tech? However, the reality is more nuanced.

Historically, some states introduced sales tax holidays to prevent consumer hopping. For example, when New York implemented a clothing exemption in 1977, the goal was to keep residents from shopping in neighboring New Jersey (where clothing was always exempt). From there, many additional states implemented their own sales tax holidays in a similar attempt to increase local revenue.

As economist Michael D. LaFaive put it:

“… Shoppers may shift purchases into the tax-free period … but the total effect depends heavily on the scope of the policy. Broad, long holidays covering durable goods produce noticeable changes in consumer behavior. Narrow holidays—such as those limited to clothing or school supplies and just for a few days—often do not.”

In short, sales tax holidays influence timing more than geography.

So… Is Cross-Border Shopping Still a Big Deal?

Unfortunately, the answer is both yes and no.

There’s no question that cross border shopping used to have a larger impact, particularly before the rise of e-commerce and the implementation of modern tax collection rules.

Today, it’s more limited to border regions and high-value purchases, and is less relevant for everyday consumer behavior.

At the same time, it hasn’t disappeared entirely. States still need to consider:

• Revenue leakage, as consumers spend money elsewhere.
• Retail distortion, as businesses cluster in lower-tax areas.
• Competitive pressure, as jurisdictions adjust policies to retain economic activity.

And underlying all of this is the broader question: is sales tax regressive?

Many economists argue that it is, since lower-income households spend a greater share of their income on taxable goods. And cross-border shopping can amplify this effect, as higher-income consumers are more likely to take advantage of tax saving strategies like travel or timing purchases.

What This Means for Businesses

For businesses, the takeaway isn’t just about consumer behavior—it’s about complexity.

The shift from physical cross border shopping to a destination-based, multi-state system has created a new reality: you’re not just competing on price anymore. Rather, you’re navigating a patchwork of tax rules that follow your customer wherever they are.

That means managing:

• Multi-state nexus thresholds
• Destination-based sourcing rules
• Sales tax holiday compliance
• Audit risk across jurisdictions

In other words, while consumers may not be hopping borders as often, businesses are now responsible for keeping up with all of the border rules.
