No matter the size of a company or the breadth of its products and services, they all need tax software that can bridge disparate and siloed data to manage the tax compliance process end to end. Having reliable APIs is the first step in achieving this goal.

The more you sell, the more often you’ll file returns. Like most things sales tax-related, the requirements and deadlines vary from state to state. You can look up deadlines on each state’s department of revenue site or in our state sales tax guides.

First, determine where you have nexus. Keep in mind that New Hampshire, Oregon, Montana, Alaska, and Delaware (the NOMAD states) do not collect sales tax. The remaining 45 states and Washington, D.C. all have some form of transaction tax. Start with where you have physical nexus, then identify where you’ve triggered economic nexus. 2. Next, register in each state in which you have nexus. Registering through Avalara Licensing is easier than registering with individual departments of revenue. 3. After you register, you’ll need to collect sales tax in the states you’ve registered in, then submit returns and remit the taxes to the proper tax authority. Avalara can help with this, end to end.

Some states require you to register if you sell via Fulfillment by Amazon (FBA), others count FBA sales toward economic nexus thresholds. Additional states have marketplace facilitator laws in place, requiring marketplaces to collect and remit sales tax on behalf of sellers. And if you sell through multiple channels, you may still trigger nexus and be required to register and remit on your own, even in states that collect from marketplaces.
