Ohio Marketplace Facilitator Sales Tax: Amazon, Etsy & eBay Rules

Quick answer: Under Ohio Revised Code § 5741.07, marketplace facilitators like Amazon, Etsy, Walmart, and eBay are legally required to calculate, collect, and remit Ohio sales tax on all third-party orders delivered to Ohio. If you sell exclusively through these platforms, the marketplace handles the tax. But if you also make direct sales through your own website, you must report marketplace sales on your UST-1 return to prevent audit discrepancies.

Ohio enacted its Marketplace Facilitator statute to simplify collection from hundreds of thousands of independent e-commerce sellers. While the law removes day-to-day tax collection burdens for pure marketplace sellers, it introduces complex reporting requirements for multichannel merchants who sell on both marketplaces and direct websites.

Here is how Ohio's marketplace facilitator law works, who is responsible for what, and how to avoid the automated notice trap on your state returns.

What Is a Marketplace Facilitator Under Ohio Law?

Under Ohio Revised Code (R.C.) § 5741.01(X) and § 5741.07, a marketplace facilitator is defined as any entity that:

1. Operates a marketplace (physical or electronic, such as a website, software app, or catalog) where tangible personal property or taxable services are offered for sale; and
2. Directly or indirectly collects payment from the consumer and transmits the payment to the third-party seller.

Prominent examples of qualifying marketplace facilitators include:

• E-Commerce Marketplaces: Amazon, eBay, Walmart Marketplace, Etsy, Poshmark, Mercari
• Food Delivery Platforms: DoorDash, Uber Eats, Grubhub
• App Stores & Digital Platforms: Apple App Store, Google Play Store

The Legal Burden: Who Is Liable for Uncollected Tax?

Under R.C. § 5741.07(A), the marketplace facilitator is treated as the retail seller for all sales tax purposes:

"A marketplace facilitator shall be treated as the seller with respect to each retail sale made through its marketplace... and is solely responsible for collecting and remitting the tax imposed by this chapter."

This statutory language provides critical legal protection to third-party sellers: If Amazon or Etsy makes a software error and under-collects sales tax on an Ohio transaction, ODT audits and assesses the marketplace, NOT you.

What Happens When You Sell on Both a Marketplace and Your Own Website?

The most common compliance mistake occurs when an online brand sells through multiple channels—such as running a Shopify or WooCommerce store alongside an Amazon storefront.

The Problem: Form 1099-K Discrepancies

At the end of each year, payment processors (Stripe, PayPal, Shopify Payments) and marketplaces (Amazon, Etsy) report your gross transaction volume to the IRS and the Ohio Department of Taxation on Form 1099-K.

If your business generated:

• Amazon Gross Sales: $400,000
• Shopify Direct Sales: $100,000
• Total Form 1099-K Gross Volume: $500,000

If you file your Ohio sales tax returns (Form UST-1) reporting only your $100,000 in direct Shopify sales, ODT's automated matching computers will flag a $400,000 gross revenue discrepancy. Within weeks, you will receive an audit assessment or inquiry letter demanding an explanation.

The Correct Way to File Form UST-1:

1. Line 1 (Gross Sales): Enter your total gross receipts from all sources ($500,000).
2. Line 2 (Exempt Sales): Deduct sales where tax was remitted by a facilitator ($400,000), plus any out-of-state sales and exempt items.
3. Line 3 (Net Taxable Sales): The remaining balance equals your taxable direct sales ($100,000).
4. Tax Calculation: Apply your origin county rate (for in-state sellers) or customer destination rates (for remote sellers).

The Trench Truth: Never leave marketplace sales off Line 1 of Form UST-1. Reporting total revenue on Line 1 and claiming the legal marketplace deduction on Line 2 provides a clean audit paper trail that automatically reconciles against your annual 1099-K tax documents.

County Sales Tax Rates for Direct Sales

When fulfilling non-marketplace direct sales to Ohio customers, you collect the combined state (5.75%) and county sales tax rate (6.50% to 8.00%):

Do Pure Marketplace Sellers Need an Ohio Vendor's License?

• If you sell 100% on marketplaces: If every single dollar of your sales flows through Amazon, Etsy, or eBay, and you make zero sales through your own website, phone, or in-person pop-ups, you are not required to hold an Ohio Vendor's License.
• If you already have a license: If you registered a vendor's license in the past and then switched exclusively to marketplace sales, you cannot simply stop filing. You must either log in and file zero returns or formally cancel the license with ODT. An unfiled return incurs a $50 penalty under R.C. § 5739.12(D).

Deadlines & Filing Schedule

For merchants holding an active vendor's license:

• Return Due Date: Monthly returns (Form UST-1) are due on the 23rd of the month following the period close (rolling to the next business day on weekends/holidays).
• Zero Returns: Mandatory for every active account.
• Interest: Unpaid tax accrues statutory interest at 7.0% per annum for 2026 under R.C. § 5703.47.

Frequently Asked Questions

What is Ohio's Marketplace Facilitator Law? Under Ohio Revised Code § 5741.07, any marketplace facilitator (such as Amazon, Etsy, eBay, or Walmart) that facilitates more than $100,000 in gross Ohio sales must collect and remit Ohio sales tax on behalf of all third-party marketplace sellers.

Does Amazon collect sales tax for third-party sellers in Ohio? Yes. Amazon automatically calculates, collects, and remits the correct combined Ohio state and county sales tax on all customer orders delivered to Ohio addresses.

Do I need to file an Ohio sales tax return if I only sell on marketplaces? If you sell 100% through registered marketplace facilitators and make no direct sales (no independent website, no retail store), you generally do not need an Ohio vendor's license or monthly return filing. However, if you hold an active vendor's license, you must file periodic returns.

How do I report marketplace sales on Ohio Form UST-1? Enter your total gross receipts from all channels (including marketplace sales) on Line 1 (Gross Sales). Then, enter your marketplace facilitator sales on Line 2 (Exempt Sales). This shows ODT why sales tax was not remitted on those transactions.

Do marketplace sales count toward Ohio's $100,000 economic nexus threshold? Yes. Gross sales made through marketplace platforms are included when calculating whether an out-of-state business exceeds the $100,000 economic nexus threshold under R.C. § 5741.01(I).
