Chapter 3: Getting registered to collect Colorado sales tax
The first step toward proper management of Colorado sales tax involves getting registered with the Colorado 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 Colorado 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 Colorado?
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 Colorado, inventory in Colorado, 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 Colorado, the Colorado 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 Colorado, 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 Colorado 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 Colorado, a business that has established nexus within the state is required to register for an sales tax license.What triggers nexus in Colorado?
Nexus is a complex topic that, depending on your situation, may require the in-depth knowledge of a qualified tax professional. That being said, there are a few common business events and situations that are known to trigger nexus in Colorado. The most common include the following:
