New Sales Tax Laws in the US: the eCommerce Impact

New Sales Tax Laws in the US the eCommerce Impact

With 52 different states and jurisdictions + a dizzying amount of sales tax laws, how will merchants keep up? 


Sales tax is a big source of revenue for states. It is in each state’s best interest to be vigilant about getting paid. Up until 2018, there were some distinct grey areas when it came to online or remote retailers paying state sales taxes. Previously, merchants weren’t responsible for collecting and remitting sales tax if they did not have a physical presence in the state in question.

The Supreme Court decision South Dakota v. Wayfair has changed the status quo.

South Dakota law now requires online retailers to collect and remit sales tax if the retailer sells more than $100,000 in the state or completes at least 200 transactions with South Dakota residents.

Other states are enacting their own sales tax laws.

On Oct. 1 of 2018 the following states enacted their own changes to their respective laws:

  • Alabama
  • Illinois
  • Indiana
  • Kentucky
  • Massachusetts
  • Michigan
  • Minnesota
  • North Dakota
  • Washington
  • Wisconsin

Among the 52 different states and other jurisdictions, there will be different tax rates. The tax rates will depend on what is being sold (products AND services) and possibly the jurisdiction where consumers reside. So one customer who lives across the street from another could be imposed a different sales tax rate as a result of unique taxing jurisdictions.

The consequences of not complying with the new laws

According to the Small Business Administration (SBA), “as a small business owner, you are required to assess sales tax, collect it and pass it on to the appropriate authorities within the prescribed time.”

If you aren’t compliant with the different sales tax laws, you run the risk of:

  • Assessment
  • Audit
  • Lien
  • Referral to a collection agency
  • Or referral to the Office of the Attorney General of that state

This also applies to Canadian retailers doing business in the United States.
