When it comes to sales tax nexus updates, Wyoming was ahead of the curve. The Cowboy State passed rules requiring remote sellers to collect and remit sales tax even before the Supreme Court’s South Dakota v. Wayfair, Inc. decision. However, Wyoming had to stay implementation of those rules until the Court made its ruling. Below we have highlighted key points in the Wyoming sales tax nexus.

Enforcement date:
February 1, 2019.

Sales/transactions threshold:
$100,000

Measurement period:
Threshold applies to the previous or current calendar year.

Included transactions/sales:
Retail sales of tangible personal property delivered into the state.

When You Need to Register Once You Exceed the Threshold:
Next transaction.

Summary: According to state law, remote sellers must collect Wyoming sales tax when their gross revenue from sales into Wyoming exceeds $100,000 in the current or immediately preceding calendar year. Marketplace facilitators must also collect Wyoming sales tax when their gross revenue from sales made or facilitated into Wyoming exceeds $100,000.

Even with Wyoming implementing economic nexus law fairly in line with Wayfair, remote sellers and marketplace facilitators must ensure that they stay current on all regulations related to sales tax.
