Proactive Sales Tax Risk Management.
We view sales tax assessment not as a one-time compliance checkbox but as an ongoing strategic function that protects your bottom line. Our systematic approach thoroughly analyzes every touchpoint where your business touches a state customer locations, inventory storage, remote employees, third-party fulfillment, and digital marketplace activity. We consider your unique business structure (LLC, S-Corp, C-Corp, Partnership), sales channels (direct DTC, Amazon, Shopify, retail stores), and growth trajectory when evaluating obligations in each jurisdiction.
Whether you’re navigating California’s aggressive audit environment, Texas’s destination‑sourcing rules, or complex multi-state apportionment considerations, our dedicated team supports you through every stage of your business lifecycle.
Why Sales Tax Assessment is Important for Your Business
Every business, from e-commerce startups in Silicon Valley to retail operations in Texas, faces growing complexity in sales tax obligations. Since the South Dakota v. Wayfair, Inc. ruling eliminated physical presence as the sole nexus standard, states have aggressively adopted economic nexus laws that trigger tax obligations based solely on sales volume or transaction counts within their borders. Over 60% of small businesses face a sales tax audit within five years of expansion, with the average assessment exceeding $50,000 in back taxes and interest.
Our sales tax assessment service identifies where your business has established nexus under current state laws (economic, physical, affiliate, or click-through nexus), quantifies prior unremitted tax exposure, and provides a clear compliance roadmap. Whether you operate in California, New York, Florida, or across multiple states, our team ensures your sales tax position is documented, compliant, and defensible. We don’t just react to notices we proactively assess your entire multi-state footprint so you can scale without hidden tax liabilities.

Frequently Asked Questions
What is the difference between a sales tax assessment and a sales tax audit?
An assessment determines your total tax owed either self‑reported on a return or calculated by a tax authority after an audit. An audit is the formal examination a state conducts to verify compliance, which can result in an assessment of back taxes, penalties, and interest. We focus on proactive assessment before an audit begins.
What are economic nexus thresholds?
Most states with a sales tax have adopted economic nexus laws that require registration once your business exceeds a certain threshold typically $100,000 in annual sales or 200 transactions in that state, regardless of physical presence.
Do I need a sales tax assessment if I already use an online platform?
Yes. Even if you sell through Amazon, Etsy, or other marketplaces, you may still have independent filing obligations for your direct sales, and marketplace facilitator laws vary by state. A comprehensive assessment covers all channels.
How far back can states go in a sales tax audit?
Most states have a three‑to‑four‑year statute of limitations for assessments, but if no return was filed, there is generally no limitation period. Identifying exposure early allows you to file voluntarily and limit lookback exposure.
What is a voluntary disclosure agreement (VDA)?
A VDA is a program offered by most states that allows businesses to voluntarily come forward and register for past periods in exchange for waived penalties and a limited lookback period (typically three to four years). Our team prepares and submits VDAs on your behalf.
Do you handle sales tax registration and filing after the assessment?
Absolutely. Following the assessment, we can register your business in all required states, set up tax calculation tools, prepare and file returns, and provide ongoing compliance management.
