How quickly can you register for sales tax in new states? Wacky Tax Wednesday

It’s the goal of many businesses to increase sales and expand into new markets. Yet, now that most states tax sales by out-of-state sellers, such growth often brings new sales tax collection obligations. These can take effect surprisingly quickly.

A little background is in order.

Taxing remote sales is relatively new. Since the first states established their sales tax systems in the 1930s, states have had limited taxing authority over businesses based in other states. Indeed, the Supreme Court of the United States ruled more than once during the 20th century (notably in National Bellas Hess, Inc. v. Department of Revenue of the State of Illinois and Quill Corp. v. North Dakota) that states could not require a business to collect and remit sales tax unless the business had a physical presence in the state.

But the Supreme Court overruled that longstanding physical presence rule in its South Dakota v. Wayfair, Inc. decision (June 21, 2018); it determined ecommerce had “changed the dynamics of the national economy” to the extent that the physical presence rule had become “a judicially created tax shelter” for certain businesses. In so ruling, it allowed states to base a sales tax collection obligation solely on a remote seller’s sales in a state, or economic nexus.

And so, the floodgates were opened.

Today, approximately 18 months after the seminal ruling, 43 states and Washington, D.C. have economic nexus laws or rules requiring out-of-state businesses with a certain amount of sales in the state to register their business, collect and remit sales tax, and file returns. Florida and Missouri will likely soon follow suit.

The five remaining states — Alaska, Delaware, Montana, New Hampshire, and Oregon — don’t have a statewide sales tax. However, local governments in Alaska are interested in requiring remote retailers to collect and remit their local sales taxes.

All this is to say that if you’re in the business of making sales, you could already be liable for sales tax in states where you make sales but aren’t collecting. And if your business is growing, your collection obligations could grow, too.

The importance of economic nexus thresholds

Except in Kansas, all state economic nexus laws or rules provide an exception for small sellers. To that end they’ve all established an economic nexus threshold: Sell below the threshold and you don’t have economic nexus; sell above it and you probably do.

Thresholds vary from state to state and include:

  • $100,000 in sales (e.g., Massachusetts and North Dakota)
  • $100,000 in sales and 200 transactions (e.g., Connecticut)
  • $100,000 in sales or 200 transactions (e.g., South Dakota and Wisconsin)
  • $150,000 in sales (e.g., Arizona)
  • $250,000 in sales (e.g., Alabama)
  • $500,000 in sales (e.g., California and Texas)

Keep in mind that states include different transactions in their thresholds; electronically delivered products, digital goods, exempt sales, or services should be included when calculating the threshold in some states but not others. Some states want retailers to include sales made through a marketplace, while others don’t. Individual state threshold information is available in our state-by-state guide to economic nexus laws and state-by-state registration requirements for marketplace sellers.

If you sell into states where you’re not collecting sales tax, you should check to see whether your sales in those states have crossed the economic nexus threshold. If they have, you may have developed a sales tax collection obligation in one or more states. A trusted tax advisor can help you determine your next step.

The importance of tracking your sales

If you haven’t crossed an economic nexus threshold but do make sales into states where you don’t collect, it’s important to monitor your sales in those states closely. In some states, you need to register with the tax authority and start collecting sales tax as soon as you cross the threshold. As in, tax must be applied to the very next sale.

That’s the wacky part.

It appears you must register with the tax department before the next invoice after crossing the threshold in the following states:

  • Arkansas
  • California
  • District of Columbia
  • Georgia
  • Idaho
  • Indiana
  • Maine
  • Mississippi
  • South Dakota
  • Utah
  • Wyoming

In Ohio, you must register the day after you cross the threshold. The remaining states give you a bit more time: 30, 60, or 90 days after crossing the threshold, by the next quarter, or by January 1 of the following year.

Do the above states really expect businesses to register so quickly after they cross their economic nexus threshold? What will they do if you don’t?

I don’t know. I do know that these policies seem to suggest that states expect businesses to closely monitor their sales into all states. And I know they’re eager to collect remote sales tax revenue.

States take this stuff seriously. They wouldn’t bother creating thresholds if they didn’t matter. To learn more about how states tax remote sales, check out our guide to sales tax nexus laws.
