USA Amazon Sales Tax Filing

I run an Amazon-based business that ships nationwide and I need a seasoned accountant to take full ownership of my sales-tax compliance in every U.S. state. The job centres exclusively on tax preparation—no ongoing bookkeeping or income-tax work—so I’m looking for someone who already knows the ins and outs of marketplace facilitator laws, state-specific thresholds and the quirks of Amazon Seller Central reports. Your role is to: • Determine and confirm nexus or filing requirements across all states and any relevant local jurisdictions • Register the business where required and keep those accounts current • Pull accurate sales data from Amazon, reconcile it (QuickBooks Online and CSV exports available), and prepare timely returns • File each return on schedule—monthly, quarterly or annually, depending on the state—and provide proof of submission • Advise me on best-practice record-keeping so I’m always audit-ready I currently use QuickBooks Online and have experimented with both TaxJar and Avalara, so experience with those platforms—or a comparable solution you prefer—is important. Please outline which software you’ll use, your approach to data validation, and how you structure communication so I always know what’s been filed and what’s coming up. Success for me means zero late filings, zero penalties and clear, organised records I can hand straight to my CPA at year-end. If that matches your workflow, I’m ready to get started right away.
