Marketplace Facilitators & Sales Tax Guide for Sellers

May 29, 2025

What is a Marketplace Facilitator?

A marketplace facilitator is a business or platform that helps third-party sellers reach customers (e.g., Amazon, eBay, Etsy).
These platforms often handle transactions, logistics, and sometimes… taxes

Nexus and Marketplace Sales

 Even if you're selling through a third-party platform, the revenue generated counts toward economic nexus thresholds.
👉Don't ignore these figures when assessing your tax obligations.

Who collects the sales tax?

✅If the marketplace collects and remits, you're likely covered.
If not, it's your responsibility to:

  • Register with the state
  • Collect tax from buyers
  • File appropriate returns

Who is a Wholesaler?

  • Buy in bulk from manufacturers or distributors, sell in smaller quantities to businesses/retailers
  • Operate warehouses, handle logistics & focus on volume
  • Require resale certificates to avoid sales tax on B2B transactions

Who is a Retailer?

  • Sell directly to consumers
  • Must collect sales tax unless a valid resale certificate is presented
  • Taxable at the point of final consumption

What is a Resale Certificate?

A resale certificate lets a business buy goods without paying sales tax, if they plan to resell them.

  • Issued by state tax authority
  • Prevents double taxation (sales tax is collected only at the point of final consumer)
  • Must be retained as proof to comply with tax regulations & avoid audit penalties

Why this matters

  • Misunderstanding roles (seller vs. facilitator)
  • Not tracking nexus thresholds
  • Not collecting/keeping resale certificates

…can lead to audit risk and penalties.

Sales tax rules are only getting more complex.

  • Nexus evaluations
  • Marketplace compliance
  • Reseller documentation
