Muddasir A.

I'm a U.S. Sales Tax Specialist with 6+ years of experience helping eCommerce businesses stay compliant across multiple states. I cover the full compliance lifecycle — Shopify sales tax setup, economic nexus analysis, state registrations, return filing, and ongoing multi-state compliance. On the accounting side, I work with QuickBooks for bookkeeping, transaction categorization, reconciliations, and financial record management — so your books and your filings always tell the same story. For online sellers, I identify nexus obligations, automate tax collection through Shopify and Avalara, and file accurate monthly, quarterly, and annual returns. My focus is simplifying complex tax processes — saving you time, reducing audit exposure, and keeping every filing audit-ready. Detail-oriented, reliable, and committed to clear communication and on-time delivery on every engagement.
