SalesVAT ‑ OSS/IOSS Solution vs Sidr ‑ Sales Tax Automationfor Shopify (2026)
SalesVAT ‑ OSS/IOSS Solution and Sidr ‑ Sales Tax Automation are both highly rated Shopify apps focused on automating sales tax compliance, but they cater to fundamentally different geographic markets. SalesVAT specializes in European Union VAT compliance, focusing on OSS and IOSS reporting, IOSS registration, and fiscal representation. It's tailored for businesses selling into or across the EU. Sidr Tax, on the other hand, is a US-based solution targeting US sales tax compliance. It handles nexus tracking, registration, reporting, and filing automation for US states. The key differentiator lies in their geographic focus. SalesVAT empowers merchants navigating the complexities of EU VAT, ensuring compliance and preventing surprise charges for European customers. Sidr Tax simplifies US sales tax compliance, providing automation and accuracy for merchants selling within the United States. Choosing between the two depends entirely on where the merchant's primary sales activity occurs and the regulatory landscape they need to navigate. While both offer strong support features, Sidr boasts significantly more reviews, suggesting a more established user base and potentially more readily available community support.

Our Verdict
The choice between SalesVAT ‑ OSS/IOSS Solution and Sidr ‑ Sales Tax Automation hinges on the merchant's sales region. If a Shopify store sells primarily into the European Union and needs assistance with OSS/IOSS compliance, SalesVAT is the clear choice. Its features are specifically designed to navigate the complexities of EU VAT regulations.
Conversely, if a Shopify store's primary sales occur within the United States, Sidr Tax offers a comprehensive solution for US sales tax compliance. Its focus on nexus tracking, registration, and automated filing provides significant value for merchants seeking to streamline their US tax obligations. While SalesVAT shows a perfect rating, its limited number of reviews should be considered, as Sidr Tax has a larger and more established user base demonstrating a greater level of confidence in the app's reliability and effectiveness.
