What 1stopVAT does

1stopVAT is a B2B indirect tax compliance services firm headquartered in Vilnius, Lithuania, founded in 2019 and operating as a private company (legal entity UAB 1stopVAT). The company manages the full VAT lifecycle — registration, periodic filing, consulting, and reporting — for businesses operating across 100+ jurisdictions worldwide. Its core customer segments are cross-border e-commerce sellers, digital service providers, marketplace sellers, and US companies expanding internationally, with named enterprise references including Surfshark, Kilo Health, and Nord Security. The firm operates a hybrid sales-led and inside-sales motion pairing dedicated multilingual account managers with self-service digital tools and a free-consultation entry point, with publicly disclosed modular pricing (€130 per US return, €100/month for UK/EU compliance, €120/month for OSS services).

The service portfolio spans three core offerings — VAT Registration, VAT Compliance & Filing, and VAT Consulting — supplemented by specialized modules addressing newer regulatory regimes: EPR services for Germany, France, and Spain; CBAM services for EU carbon border adjustment (transitional Oct 2023–Dec 2025; definitive from Jan 2026); US Sales Tax services across 45 states; Voluntary Disclosure Agreements for retrospective regularization; and E-Invoicing solutions aligned with the EU's ViDA directive. The underlying technology is described as an integrated compliance platform featuring automated tax data collection, deadline monitoring, and integrations including the Amazon Services API for client sales-data ingestion and Quaderno's real-time tax calculation engine. Free online calculators (VAT, GST, Sales Tax, VAT Number Checker) function as lead-generation tools feeding into a free compliance review entry point.

Commercially, 1stopVAT reports managing more than 12,000 VAT returns annually for over 1,000 clients using a team of 40+ certified tax experts (members of IVA, AITC, and VAT Forum). No external funding rounds are disclosed and the firm appears to be independently operated without venture capital or private equity backing. The company maintains strategic partnerships with Quaderno, FLEX., and Fexco International Payments to offer integrated tax-compliance-plus-execution services, and holds GDPR-compliant data handling as both Data Controller and Data Processor across all jurisdictions served.
