    The Problem

    Why Sales Tax Compliance
    Has Become So Complex

    The regulatory landscape shifted overnight after Wayfair. States now track your sales volumes rather than physical presence and the consequences of getting it wrong are severe.

    • Wayfair Economic Nexus Rules

      States require filing once you hit $100K–$500K in sales even with zero physical presence. Thresholds vary wildly by state and tracking period.

    • Multi Channel E-Commerce Complexity

      Amazon, Shopify, your own site each channel creates different nexus obligations. Manual tracking across all of them is impossible and error prone.

    • Escalating Penalties & Retroactive Liability

      A missed filing triggers interest charges. Late discovery of an unregistered state creates retroactive liability going back years. What starts small compounds fast.

    • Constantly Changing Regulations

      States update thresholds. Marketplace facilitator laws shift. Most businesses discover changes only when auditors point them out which is too late.

    • Overpayments You Don't Know About

      Calculation errors and improper registrations lead to money left on the table. Most businesses never file for refunds they're legally owed.
