Poshmark Sales Tax Guide for Sellers in 2026

Does Poshmark Collect Sales Tax For You?

Yes. Poshmark is a marketplace facilitator and collects and remits sales tax on all transactions in states where marketplace facilitator laws apply. Sellers don't need to collect or remit for Poshmark sales.

What You Still Owe Even If Poshmark Collects

Resale certificates: If you purchase inventory that you resell on Poshmark, you may be able to purchase that inventory tax-free using a resale certificate (exempt from sales tax at the wholesale level). This is separate from your Poshmark seller obligations but can reduce your inventory costs.

Multi-channel sellers: If you sell on Poshmark AND eBay AND Depop AND your own store, CA, NC, MI, WA aggregate all channels for threshold purposes. Your combined multi-platform reselling volume may create direct-channel nexus obligations.

Washington B&O: Large-volume Poshmark sellers who exceed $100K Washington sales may owe B&O tax even though Poshmark handles sales tax.

Your Nexus Exposure on Poshmark

Poshmark sellers are typically resellers of pre-owned clothing and accessories. Used clothing is generally taxable (with the exception of states that broadly exempt clothing like PA, NJ, MN). Pre-owned status doesn't create a tax exemption in most states.

High-volume Poshmark resellers selling across multiple platforms — especially those who also operate their own Shopify stores — can accumulate meaningful nexus exposure in major states.
