Scott Letourneau presents strategies for Amazon FBA sellers who are behind on sales tax reporting and remittance. He discusses determining which states you have nexus in based on inventory locations, calculating how much tax is owed, and options like applying for past due permits and paying owed taxes/penalties or pursuing a voluntary disclosure agreement to waive penalties. Letourneau recommends services from Taxify to pull sales data and file returns, and from Sales Tax System to apply for permits going forward to help sellers get into compliance and move past due tax obligations.
