How Marketplace Facilitator Laws Work
After South Dakota v. Wayfair (2018), all 45 sales-tax states enacted marketplace facilitator laws requiring platforms like Amazon and eBay to collect and remit sales tax on behalf of third-party sellers. As a seller, this means the platform handles collection on marketplace sales β but you remain responsible for direct sales tax, nexus registration, and accurate income reconciliation.
The Formula
Marketplace Tax Collected = Marketplace Sales Γ Avg Platform Rate (handled by platform)
Direct Tax Owed = (Direct Sales β Exempt Sales) Γ Your Avg Rate
Taxable Direct Sales = Direct Sales β Exempt Sales
1099-K Expected = Marketplace Sales + Direct Sales (gross)
Federal Threshold: >$20,000 AND >200 transactions (2026)
Direct Tax Owed = (Direct Sales β Exempt Sales) Γ Your Avg Rate
Taxable Direct Sales = Direct Sales β Exempt Sales
1099-K Expected = Marketplace Sales + Direct Sales (gross)
Federal Threshold: >$20,000 AND >200 transactions (2026)
Example
$85K Amazon + $15K direct website sales, 320 total transactions:
Amazon collects sales tax on $85K β you owe $0 to states for those sales
Direct website sales: $15K Γ 7.5% = $1,125 you must collect & remit
1099-K: $85K (Amazon) β exceeds $20K + 200 txn β expect 1099-K from Amazon
State low-threshold states (MA/VA/IL/NJ): $600 threshold β 1099-K if over $600
Action items: register in nexus states, remit $1,125 direct sales tax

Frequently Asked Questions
What is a marketplace facilitator and who qualifies?
A marketplace facilitator is a platform that facilitates retail sales on behalf of third-party sellers β including listing products, processing payments, and collecting customer data. Amazon, eBay, Etsy, Walmart Marketplace, and Target Plus all qualify. Under marketplace facilitator laws (enacted in all 45 sales-tax states after South Dakota v. Wayfair), these platforms are required to collect and remit sales tax on third-party sales, removing the obligation from individual sellers for those transactions.
Do I still need to register in states where a marketplace collects tax for me?
Yes β even if a marketplace collects tax on your behalf, you may still need to register in states where you have nexus (physical presence, employees, inventory in Amazon FBA warehouses, or economic nexus from your direct sales). Registration ensures you can file returns, report exempt sales, claim resale certificates, and reconcile your 1099-K correctly. Many states require sellers to maintain registration even if a marketplace handles all collection.
What is the 2026 federal 1099-K threshold?
The federal 1099-K reporting threshold for 2026 is $20,000 in gross payments AND more than 200 transactions from a single payment processor or marketplace. However, several states have lower thresholds: Massachusetts, Virginia, Illinois, and New Jersey apply a $600 threshold for 2026, regardless of transaction count. You may receive a 1099-K even if your net income after costs is minimal β it reports gross receipts, not profit.
How do I reconcile 1099-K income with my tax return?
1099-K reports gross payment card and third-party network transactions. For Schedule C filers, you report this on gross receipts, then deduct cost of goods sold, platform fees, shipping, and other expenses. For marketplace sales where the platform collected sales tax on your behalf, that tax should not be included in your gross income β it is a pass-through. Check that your gross revenue on Schedule C matches or reconciles with all 1099-Ks received, noting returns, refunds, and fee deductions.
What are my sales tax obligations for direct (off-marketplace) sales?
For sales made outside of a marketplace β on your own website, at craft fairs, or via direct invoice β you are solely responsible for collecting and remitting sales tax in states where you have nexus. The economic nexus threshold in most states is $100,000 in sales or 200 transactions in the prior or current calendar year. Direct sales must be tracked separately from marketplace sales for state return filing purposes.
