Common Sales Tax Challenges

Tracking Where You Have Nexus

Nexus is the connection you have between a state or local taxing jurisdiction. Without nexus, you have no sales tax obligation. Nexus is determined by either a physical or economic presence. Tracking it isn’t always easy though. 

Ever since economic nexus was enacted in 2018, states have been changing their thresholds. When you work with TaxConnex, we can help you identify where you have nexus and help you monitor your footprint going forward.

Understanding Taxability

Once you’ve determined nexus, you need to determine if your products and/or services are taxable. For some, this is an easy answer. But for many industries, the answer is not so straightforward. Just like with nexus, states differ in their taxability laws.  

TaxConnex can perform a taxability review to help you understand where your products or services are taxable and help you manage this as your business grows (expansion into new states, changing laws, new product launches and mergers or acquisitions).

Navigating Prior Period Exposure 

If you haven’t been collecting and remitting sales tax but have a responsibility to do so, it’s very possible you’ve developed some prior period exposure.  The longer you’ve neglected your obligation, the larger the amount owed (and penalties and fees) will be. But, there are options.  

TaxConnex can help you calculate your prior period exposure and guide you to make the right decision in how to mitigate your exposure and create a process to move forward in compliance.
