Whether you need a trusted advisor for ongoing decisions or targeted help with a specific issue, we provide clear, practical guidance tailored to your business and needs.

What's included

Advisory & Registrations services

Nexus & Exposure Analysis

Nexus is straightforward until it isn't. Tax CSA helps you quickly understand where you have tax obligations, where you may have unaddressed exposure, and what action is needed. A clear picture of where you stand is the foundation of everything else.

Sales Tax Advisory

Looking for a trusted advisor who can learn your business and provide a clear roadmap of what's ahead? Tax CSA's consultants provide practical guidance for complex sales tax questions, transactions, and business decisions. You get consistent answers from people who know your situation, not a different opinion every time you call.

Marketplace Advisory

Marketplaces operate under a distinct and evolving set of rules. Whether you're just getting started or expanding your footprint, Tax CSA helps you navigate marketplace facilitator laws, seller obligations, and the tax implications of selling through third-party platforms, so you're not caught off guard as the rules shift.

Business Licensing, Registrations & Renewals

Not sure where to register, or for what, in each jurisdiction? Don't have the time or appetite for the research required in every state? Worried about missing a renewal? Tax CSA manages new registrations and renewals on your behalf, keeping your business compliant as it grows. Coverage includes Secretary of State registrations, sales and use tax registrations, business licenses, and specialty licenses for tobacco, vape, PACT registration, and telecommunications.

Voluntary Disclosure Agreements (VDA)

Unaddressed historical exposure doesn't go away, but it can often be resolved through a structured voluntary disclosure process. Tax CSA helps companies reduce potential state liability by managing the VDA process from start to finish.

Economic Nexus Monitoring

Have a tax technology system but not enough time to log in and stay on top of changing sales thresholds? Tax CSA monitors your sales activity across jurisdictions so that emerging tax obligations don't catch you by surprise.

Tax Notice Resolution

A tax notice from a state doesn't always mean something is wrong but it should be reviewed to determine next steps. Tax CSA helps you interpret, respond to, and resolve tax notices with the right documentation and the right action.

Audit Readiness

The scramble that follows an audit notice is avoidable. Tax CSA helps you prepare by identifying the documentation needed, reviewing your positions, and ensuring your team has clean and organized records. The goal is a smooth process and a defensible outcome.

White-glove service isn't a promise we make; it's a standard we live by. Our approach is built around expertise, responsiveness and being a trusted partner throughout every step of the process.
