Wayfair
Nexus Compliance
The Supreme Court's Wayfair vs. South Dakota decision changed the rules for sales tax. Economic activity alone, reaching a certain dollar or transaction volume in a state, can now trigger the requirement to collect and remit. For a growing business, monitoring these thresholds across 10,000+ local jurisdictions is a real operational and legal risk.
Our Sales Tax & Nexus practice builds and runs that compliance for you: retroactive nexus audits, automated tax calculation (TaxJar, Avalara), and ongoing management of state-level registrations and filings, so liability doesn't build up in jurisdictions no one is watching.
How we deliver this service.
A rigorous, phase-driven process ensures nothing is missed and every position is defensible.
Nexus Footprint Audit
We review your historical transaction and payroll data to identify the states where economic or physical nexus has been established.
Taxability Analysis
Our advisors review your product/service catalog to determine its taxability under the specific statutes of every relevant state jurisdiction.
Voluntary Disclosure (VDA)
For states where retroactive liability exists, we negotiate formal Voluntary Disclosure Agreements to reduce penalties and limit back-tax exposure.
System Implementation
We coordinate the integration of automated sales tax engines (Avalara, TaxJar) into your e-commerce or ERP stack for real-time calculation.
State Permit Registration
Our team handles the state-level registration process for every new jurisdiction where you have to collect sales tax.
Ongoing Managed Filings
We handle the accurate monthly, quarterly, and annual filing of sales and use tax returns across all required states and cities.
E-commerce Strategy
Compliance before the threshold is hit.
The most expensive sales tax mistake is reacting to a nexus event after a state notice arrives. We track your sales against state-specific thresholds before you hit them, so you can turn on collection early instead of paying uncollected tax out of your own margin.
We replace spreadsheets and hope with a managed indirect tax process, one that stands up to corporate due diligence and auditor examination during fundraising or M&A.
Specializations: SaaS taxability, drop-shipping compliance, and Section 263A inventory capitalization modeling.
Tailored for every client profile.
Selling into more states every quarter?
Don't let unmonitored sales tax nexus eat your margins. Put a compliance process in place that grows with you.
Specific deliverables, precisely documented.
“Sales tax follows every sale you make. We keep your multi-state expansion clean enough to satisfy both your board and the states.”
Technical clarifications.
Answers to the most frequently asked questions about how this service works in practice.
The South Dakota v. Wayfair ruling allows states to tax businesses that don't have a physical presence but have high-volume sales ('economic nexus') in that state.
State rules for SaaS vary widely. Some treat it as a taxable service, others as intangible software, and others exempt it entirely. We maintain taxability matrices for all 50 states.
We recommend a Voluntary Disclosure Agreement (VDA). States often forgive 100% of penalties if you come forward voluntarily before they contact you with a notice.
No. Any business that sells across state lines, whether consulting services, software, or physical products, has potential nexus and sales tax exposure.
