Chapter 3: Getting registered to collect Missouri sales tax

Overview

The first step toward proper management of Missouri sales tax involves getting registered with the Missouri Department of Revenue. We get a lot of questions regarding this and recognize it may be the most difficult hurdle for small businesses to overcome. Registering to collect sales tax in Missouri means you've acknowledged your legal responsibility to collect and consequently file and remit sales tax to the state.

When do I need to register to collect sales tax in Missouri?

There are two ways to think about this question. The first involves a topic called "nexus". Nexus, in the tax world refers to a company's connection to a state. While this connection is typically that of a physical nature (warehouse in the Missouri, inventory in Missouri, etc.), nexus is not limited to a physical presence. There are many nexus triggers we won't delve into here and, more importantly, nexus is often determined by a combination of events rather than a single event.

If it is determined you have nexus in Missouri, the Missouri Department of Revenue has the legal right to require you to collect, file, and pay sales tax.

If you've determined you have nexus in Missouri, the second question involves a topic we call "materiality". In short, you'll want to ask yourself whether the amount of sales tax you are required to collect and remit to the Missouri Department of Revenue is enough to put you at an unacceptable level of penalty and interest risk. As everyone's level of risk tolerance is different, this is a question that can only be answered by you, the business owner.

Prior to selling taxable goods or offering taxable services in Missouri, a business that has established nexus within the state is required to register for an Sales Tax License.
