Our Verdict
For most Shopify merchants in 2026, especially those operating in the US and dealing with sales tax complexities, Tax Rex ‑ Sales Tax Automation is the clear choice. Its positive user reviews, comprehensive feature set (including automated filing, nexus alerts, and marketplace exclusion), and clear focus on simplifying US sales tax compliance make it a compelling option. GSTFLY, on the other hand, presents too much risk due to the complete absence of user feedback and product information.
Unless there's compelling new information about GSTFLY that drastically changes its perception, merchants prioritizing reliability, functionality, and support should opt for Tax Rex. GSTFLY may be considered only by extremely risk-tolerant users willing to beta test an unproven app, but the lack of data makes it impossible to recommend confidently.
