VAT IT US Sales Tax

For businesses headquartered outside the United States, US sales tax is one of the most frequently underestimated compliance gaps. Over 12,000 different applicable rates apply across state, county, city, and special district jurisdictions. A nexus landscape that changed materially after South Dakota v. Wayfair extended economic nexus obligations to remote sellers. Most international finance teams encounter this complexity for the first time when the exposure is already material. VAT IT manages US sales tax compliance across all 50 States: nexus monitoring, calculation, filing, remittance, exemption certificates, and audit-ready recordkeeping. One team. No handoffs. No gaps. Nexus monitoring runs continuously across economic thresholds in every applicable state, with early flagging before registration is required. When a threshold is approached, registration is handled as part of the same service - no handoff, no gap.  Tax calculation is delivered in real time, integrated with your checkout, billing system, or ERP - whether that is SAP, NetSuite, QuickBooks, Xero, or others. Whether you are processing ten transactions a day or ten thousand, calculation runs silently in the background - accurate, current, and requiring nothing from your team. From sign-off to live, onboarding is fast with no drawn-out implementations.  Your dedicated account manager works directly with your team to ensure data is accurate, returns are prepared correctly, and submissions are made on time. They are available when you need them - no ticket queues, no generic support - just a dedicated point of contact who knows your business and is reachable when it matters. You also have direct access to a sales tax expert who works with your team to understand your products and ensure they are accurately classified across every applicable jurisdiction.  Exemption certificates, filings, and supporting documentation are held centrally and maintained in audit-ready condition from day one. When a state notice arrives, it does not land on your desk as a problem to solve - it is reviewed, translated into clear next steps, and handled alongside you. VAT IT works with you as an active partner - monitoring your exposure, keeping your filings clean, and making sure that as your business grows, your compliance keeps pace.
