State & Local Tax (SALT)
What nexus, sales and use tax, and multi-state filing obligations mean for your business.
Selling Across State Lines Can Create Obligations You Never Notice
Ever since economic-nexus rules took effect, a single online sale can be enough to create a filing obligation in a state you've never physically visited. These multi-state filings fall under our regular tax preparation work, and we make it a point to see that returns get filed everywhere they're actually owed.
We'll map out where you have nexus and get you registered before any notices show up.

Operational Milestones
Nexus study
Sales, payroll, and property get reviewed state by state to pin down exactly where a filing obligation exists.
Registration
Your business gets registered in every state where nexus applies, with collection and filing set up correctly from the start.
Ongoing compliance
Multi-state returns get filed on schedule, and thresholds are tracked as your footprint continues to grow.
Included Services & Outcomes
Multi-State Exposure Builds Quietly, Then All at Once
Under economic nexus, revenue alone, not physical presence, can trigger sales-tax and income-tax obligations across dozens of states simultaneously. Left unregistered, that exposure keeps building quietly, right up until a notice shows up.
Questions
State & Local Tax (SALT) FAQ
What does economic nexus actually mean?
It's the principle that lets a state require tax collection based purely on sales or transaction volume there, with no physical presence needed. Most states put thresholds in place after the 2018 Wayfair decision.
I sell online across a lot of states. Where do I actually owe sales tax?
In any state where you've crossed its economic-nexus threshold. A nexus study run against your sales data is what pins down precisely where registration and filing are required.
What if there's unregistered exposure from past years?
Many states offer voluntary disclosure agreements that cap the look-back period and waive penalties. Negotiating one of these is often the best way to resolve back exposure on favorable terms.
