Tax Services
State & Local Tax (SALT)
Nexus, sales & use, and multi-state filings handled across all 50 states.
Selling across state lines creates tax obligations you can't see.
Since economic-nexus rules took hold, a single online sale can create a filing duty in a state you've never set foot in. We determine where you owe, register you correctly, and keep multi-state filings clean.
We map your nexus and register you before notices arrive.

Included Services & Outcomes
Multi-State Exposure Adds Up Quietly
Economic nexus means revenue — not physical presence — can trigger sales-tax and income-tax obligations in dozens of states at once. Unregistered exposure compounds quietly until a notice arrives.
Questions
State & Local Tax (SALT) FAQ
What is economic nexus?
It's the rule that lets a state require tax collection based on your sales or transaction volume there — even with no physical presence. Most states adopted thresholds after the 2018 Wayfair decision.
I sell online in many states. Where do I owe sales tax?
Wherever you've crossed that state's economic-nexus threshold. We run a nexus study across your sales data to tell you precisely where you must register and file.
I think I have unregistered back exposure. What are my options?
Many states offer voluntary disclosure agreements that limit look-back periods and waive penalties. We negotiate these to resolve back exposure on the best available terms.
