Casual sellers who use Poshmark to clear out their closets may not realize their sales activity could trigger IRS reporting, creating potential tax obligations they hadn't anticipated.
Poshmark's Terms of Service underwent a substantial update on April 19, 2026, with 249 new sentences and 3 modified sentences. The specific operational changes created by these additions cannot be determined from the detection summary alone. All users should review the updated terms at Poshmark's website to identify any new policies, requirements, restrictions, or disclosures that affect their use of the platform.
View change record →Poshmark's updated Privacy Policy provides substantially more transparency about the personal data it collects (including name, address, payment details, and content you create), how it uses and shares that information, and the legal bases for processing. The policy now explicitly covers data collected across websites, mobile apps, and other platforms, and identifies collection points including account registration, purchases, listings, stories, and interactions with other users. California residents are directed to a separate supplemental privacy notice. While this change increases clarity about data practices rather than restricting new data collection, reviewing the specific uses and sharing practices described in the full policy can help you understand what data Poshmark retains and how it may be used.
View change record →Poshmark users — especially sellers — are subject to a 20% commission fee on transactions over $15 and grant Poshmark a broad, royalty-free license to use their posted content. A mandatory arbitration clause with a class action waiver significantly limits users' ability to seek legal redress through courts, which is a material restriction on consumer rights. You can opt out of the arbitration clause by sending written notice to Poshmark within 30 days of first accepting the Terms of Service.
