Sales tax nexus is the legal connection a business has with a state that requires it to collect and remit sales tax. This connection can be established in various ways, not just by having a physical presence (like an office or warehouse). Economic nexus, for example, is triggered when a business meets certain sales volume or transaction thresholds in a state, even if it has no physical presence there. Understanding your nexus obligations is crucial to avoid non-compliance and potential penalties.

Determining if you need to collect sales tax depends primarily on two factors: where you have sales tax nexus and whether the products or services you sell are taxable in those states. Sales tax laws vary significantly by state and even by locality, with some states taxing services, while others only tax tangible goods. We conduct thorough nexus studies and product taxability analyses to help you clearly understand your collection obligations.

Exemption certificates are documents provided by customers to a seller, certifying that a particular sale is exempt from sales tax. Common reasons for exemption include resale (the buyer intends to resell the item), use by a tax-exempt organization (like a non-profit), or purchase for manufacturing. As a seller, it's critical to collect and properly manage these certificates, as they serve as your audit defense. Without valid certificates, you could be held liable for uncollected sales tax during an audit.

The frequency of sales tax filings (monthly, quarterly, annually) is determined by each state and typically depends on your sales volume and the amount of sales tax you collect. States often assign a filing frequency based on your projected or actual sales upon registration. Failing to file on time or filing with incorrect information can lead to penalties and interest. We can help you determine your required filing frequency and manage the timely submission of your returns.
