Frequently Asked Questions
Find answers to the most common ecommerce tax accounting questions here. For more help, connect with RJM for a FREE consultation.
1. Do I need to collect US sales tax as an online seller?
Usually, yes. Once you cross a stateβs economic nexus threshold, or store inventory there through Amazon FBA, youβll normally need to collect and file sales tax in that state. That applies to international sellers too. Thresholds differ by state, so our consultants will work out exactly where you have obligations and what to do next.
2. What tax rules apply to my online store?
Tax rules vary by state and depend on your sales volume and where your customers live. In most cases, you must collect and file state sales tax. Itβs hard to know where you stand, but RJM can help.
3. How does ecommerce tax filing work if Iβm not US-based?
Being based outside the US doesnβt take you out of scope. If you sell into US states and cross their thresholds, youβll usually need to collect and file sales tax there. Donβt wait to get compliant. Our consultants help international sellers understand their US obligations and stay on top of filings to avoid penalties.
