If you sell goods or services to US customers, you may have sales tax nexus obligations in multiple states — even as a non-resident. We handle nexus analysis, registration, and ongoing filing so you don't face costly penalties.
Do You Have Sales Tax Nexus?
If you sell goods or services to US customers, you may be required to collect and remit sales tax — even as a non-resident. States aggressively pursue out-of-state sellers after the South Dakota v. Wayfair Supreme Court ruling. Penalties for non-compliance can reach $10,000+ per state, plus back taxes and interest. Voluntary disclosure can reduce or eliminate penalties for past non-compliance.
Understanding when you are legally required to collect and remit sales tax
Sales tax nexus is the legal connection between your business and a US state that triggers the obligation to collect and remit sales tax. There are two primary types of nexus that foreign-owned LLC operators need to understand.
A tangible presence in a state creates physical nexus. This includes:
Since the 2018 Wayfair ruling, all states can require remote sellers to collect sales tax once they exceed economic thresholds. The most common threshold is:
Important for e-commerce and SaaS founders: If you sell through Shopify, Amazon, Etsy, or any US-facing platform and have significant US sales, you likely already have economic nexus in multiple states. The threshold resets annually, so once you cross it, you are obligated for that calendar year and going forward.
End-to-end sales tax compliance — from nexus analysis to ongoing filing
We review your sales data and business activities to determine which states you have nexus in and what your obligations are.
We register your LLC with each state's taxing authority and obtain your sales tax permit so you can legally collect tax.
We prepare and file your sales tax returns on the schedule required by each state, remitting the correct amount of tax collected.
If you have past exposure in states where you didn't register, voluntary disclosure programs can significantly reduce penalties and limit lookback periods.
We manage filings across all nexus states from a single point of contact, tracking different deadlines and filing frequencies for each state.

Common questions about US sales tax for foreign-owned businesses
You are required to collect and remit sales tax once you have "nexus" in a state. Nexus can arise from physical presence (warehouse, employees, inventory) or from crossing economic thresholds — typically $100,000 in sales or 200 transactions in a given state within a calendar year. Most states adopted economic nexus rules following the 2018 South Dakota v. Wayfair Supreme Court ruling, so even remote sellers with no physical presence in the US can have filing obligations.
Not necessarily. You only owe sales tax in states where you have nexus. For most small to mid-sized online stores, that means 3–10 states — not all 50. You need to track your sales volume by state and register once you cross the threshold. Our nexus analysis reviews your actual sales data to identify exactly which states you're currently obligated in, so you register only where required and avoid over-compliance costs.
Economic nexus means a state can require you to collect sales tax based purely on how much business you do in that state — no physical presence needed. The standard threshold (used by most states) is $100,000 in sales or 200 transactions in the current or prior calendar year. Once you cross this threshold, you have 30–60 days (depending on the state) to register and begin collecting. Missing this registration window can result in back taxes plus interest and penalties on all sales made after you crossed the threshold.
If you had nexus in a state but never registered, you have exposure for back taxes (all the sales tax you should have collected), plus interest and penalties. The good news: most states offer Voluntary Disclosure Programs (VDA) that allow you to come forward proactively. VDA programs typically limit the lookback period to 3–4 years (rather than the full open period), waive penalties, and can result in a negotiated settlement. We strongly recommend voluntary disclosure before a state contacts you — the terms are far better.
Once registered in the required states, you need to file returns on the schedule assigned by each state (monthly, quarterly, or annually — depending on your sales volume in that state). Each return requires you to report total sales, taxable sales, exempt sales, and tax collected, then remit the collected tax. Missing a filing deadline triggers late penalties and interest. We manage the entire ongoing filing process for you — tracking all state deadlines and filing on your behalf each period.
We start with a nexus analysis to identify exactly what you owe — then handle registration and ongoing filing so you can focus on growing your business.
