Sales Tax filing and Nexus management
As a business owner, you know that the money collected at the point of sale is never truly yours—it is a held trust destined for the state. Managing this trust requires more than just clerical accuracy; it demands a strategic understanding of multi-state nexus, varying local rates, and the shifting landscape of economic laws.
At Phazer Insight, we join your team as the administrative backbone of your sales tax lifecycle. From initially determining where you have an obligation to file, to the final submission of your monthly or quarterly returns, our goal is to eliminate the friction of compliance so you can focus on scale.

Who Has a Sales Tax Obligation?
Identifying Your Compliance Profile
Retailers & E-commerce Sellers: Transitioning from brick-and-mortar to digital marketplaces creates complex physical and economic nexus thresholds.
Specialized Service Providers: Many "intangible" services are now taxable depending on how the benefit is received by the customer.
Marketplace Facilitators: Businesses that enable sales for third parties carry heavy direct reporting obligations in almost every state.
Remote & Out-of-State Sellers: Economic nexus rules mean you likely have a filing obligation even without a physical presence.
Contractors & Construction Firms: Navigating the line between real property improvements (non-taxable) and tangible personal property (taxable).
Manufacturers & Wholesalers: Management of resale certificates is critical to avoiding liability on non-taxed sales.
Quiz: Are You Building a 'Tax Trail' You Didn't Know About?
Navigating sales tax isn't just about where your office is located. In the modern economy, digital footprints, storage logs, and temporary services can create 'nexus'—a legal obligation to collect and remit tax—in states where you may never have set foot. Take this quick assessment to see if your business is exposed.
Do you sell products through an online marketplace like Amazon, Etsy, or Walmart?
Do you have inventory stored in a third-party warehouse (like Amazon FBA) outside your home state?
Do you use remote employees or independent contractors located in other states?
Do you attend out-of-state trade shows or use temporary pop-up shops to sell goods?
Has your online revenue or transaction count increased significantly in the last 12 months?
