About TaxJar
What You Should Know About TaxJar.
TaxJar is the most widely used sales tax automation platform for eCommerce businesses — trusted by over 25,000 companies to calculate, file, and remit sales tax across all US jurisdictions automatically.
Following the Supreme Court's South Dakota v. Wayfair decision in 2018, every state now has the authority to require sales tax collection from out-of-state sellers above economic nexus thresholds. Most multi-channel eCommerce businesses are non-compliant in at least one state and are unaware of it until they receive a notice.
TaxJar solves this through real-time rate calculation at checkout, automated return preparation, and one-click filing. Best Practicify brings specific eCommerce accounting expertise to TaxJar implementations — configuring not just the compliance automation but also the accounting layer that ensures sales tax liability is correctly captured in QuickBooks Online or Sage Intacct.
