Marketplace facilitator rules in Ohio: A Practical Guide for Sellers

Ohio’s marketplace facilitator rules generally put the sales-tax collection and remittance responsibility for facilitated taxable sales on the facilitator—not the marketplace seller—when the facilitator has substantial nexus with Ohio. Ohio’s economic-nexus test for a facilitator looks at its combined Ohio activity: its own qualifying sales and sales it facilitates for sellers. The Ohio Department of Taxation requires a facilitator that meets the applicable requirements to register for a seller’s use tax license, collect tax on taxable facilitated sales, file returns, and remit the tax.

That does not automatically settle a seller’s obligations. A marketplace seller may still need to register and collect Ohio sales or use tax on direct sales and other transactions not handled by a facilitator that is treated as the seller. Ohio also administers the Commercial Activity Tax (CAT) separately from sales tax, so a business can have two distinct Ohio tax obligations. The details depend on your sales, products, nexus, and filing status; confirm your position with the Ohio Department of Taxation or ask Sales Tax Compliance USA to review it.

What is a marketplace facilitator in Ohio?

Ohio law defines a marketplace facilitator by what it does: it owns, operates, or controls a physical or electronic marketplace through which retail sales or delivery network services are facilitated on behalf of one or more marketplace sellers, or it is an affiliate of such a person. A marketplace seller is the business offering goods or services through that marketplace. The label a business uses for itself is not decisive; the actual arrangement and activities matter.

When a facilitator is treated as the seller under Ohio’s sales and use tax law, it has the seller’s obligations for the taxable sales it facilitates. The seller’s own status does not determine whether the facilitator must collect on those transactions. A seller should keep marketplace statements and transaction records that show which sales were facilitated and what tax was collected, while separately tracking its direct sales.

When must a marketplace facilitator collect Ohio sales tax?

A facilitator with substantial nexus in Ohio is treated as the seller for facilitated sales and must register for a seller’s use tax license, collect Ohio tax from customers on taxable retail sales, file returns, and remit the tax. The facilitator’s collection responsibility applies to taxable sales it facilitates; it does not make every item or service taxable. Exemptions and the taxability of particular products or services still need to be assessed under Ohio law.

Ohio’s Department of Taxation describes collection, filing, and remittance as beginning on the first day of the first month that is at least 30 days after the facilitator establishes substantial nexus, with the requirement applying prospectively from that date. Because the start date can affect liability, a facilitator approaching a threshold should verify its measurement and start date with the Department rather than wait for a return or notice.

Ohio’s economic nexus threshold for marketplace facilitators

Ohio presumes substantial nexus for a marketplace facilitator if, in the current or preceding calendar year, either its aggregate qualifying Ohio gross receipts exceed $100,000 or it has 200 or more separate qualifying transactions into Ohio. For this test, the facilitator combines its own qualifying sales with sales it facilitates on behalf of marketplace sellers. The threshold is therefore not limited to the facilitator’s commission or the portion of a transaction it keeps.

The statutory test concerns sales of tangible personal property for storage, use, or consumption in Ohio and services whose benefit is realized in Ohio. Whether a particular transaction belongs in the calculation can depend on its nature and treatment under Ohio law. Keep transaction-level records and confirm borderline items with the Ohio Department of Taxation; do not assume that a seller’s own threshold calculation is the same as the facilitator’s combined calculation.

Do marketplace facilitators need an Ohio seller’s use tax license?

Yes. A marketplace facilitator that has substantial nexus and is treated as the seller must register for an Ohio seller’s use tax license. The Ohio Department of Taxation directs businesses to use the Ohio Business Gateway for registration and tax administration. The Department’s marketplace guidance also says facilitators should maintain separate seller’s use tax accounts for their own remittances and for tax collected on behalf of marketplace sellers, with the marketplace account identified accordingly.

Registration is not a substitute for determining which transactions are taxable or when collection begins. A facilitator should reconcile its account setup, marketplace reporting, and return treatment with the Department’s current instructions. If your business has already registered but its sales channels or responsibilities have changed, check whether the existing account structure still reflects your activity.

When does an Ohio marketplace seller need to register?

A marketplace seller should assess its own Ohio nexus and sales activity rather than assume that marketplace collection removes every registration obligation. Ohio law preserves a seller’s responsibility to collect and remit tax on sales other than those facilitated by a marketplace facilitator treated as the seller. A seller with Ohio nexus and taxable direct sales may therefore need its own seller’s use tax license and returns even when a facilitator collects on marketplace orders.

Marketplace sales can also be relevant to a seller’s broader tax analysis, but the facilitator’s combined economic-nexus test is not the same as the seller’s individual test. Inventory or other in-state business activity may also affect nexus. The exact registration position depends on the seller’s facts and current Ohio rules; confirm it with the Ohio Department of Taxation or have a compliance professional review the sales channels and records.

What tax obligations apply to your direct sales?

Marketplace collection generally covers only sales facilitated by a facilitator that is treated as the seller. For direct sales—such as orders taken through your own store or another channel not covered by that facilitator—you remain responsible for determining whether you have Ohio nexus, whether the product or service is taxable, and whether you must register, collect, file, and remit. Do not treat a marketplace’s tax collection as covering your separate direct transactions.

Ohio also has a Commercial Activity Tax (CAT) alongside sales and use tax. CAT is a separate business tax administered by the Ohio Department of Taxation, with its own rules and filing analysis; sales-tax registration or marketplace collection does not by itself resolve CAT obligations. Review both taxes independently, and verify current CAT requirements with the Department because the applicable treatment depends on the business and its Ohio activity.

Which marketplace sales are taxable in Ohio?

A facilitator must collect on taxable retail sales it facilitates when it is required to act as the seller. The fact that an order is placed through a marketplace does not make an otherwise exempt sale taxable, and the facilitator’s collection duty does not eliminate the need to apply Ohio’s product- and service-specific tax rules. Tangible personal property and taxable services may be subject to tax, while exemptions and special treatment can apply depending on the transaction.

Use the Ohio Department of Taxation’s current taxability guidance to classify products, services, shipping or delivery charges, and exemption claims. Sellers should provide accurate product descriptions and valid exemption documentation where applicable, and reconcile marketplace tax reports to order records. If a product’s treatment is unclear, confirm it with the Department rather than relying on a general category or a marketplace’s default setting.

How to report and remit Ohio sales tax

A facilitator treated as the seller files Ohio returns and remits the tax it collected on taxable facilitated sales. The Ohio Department of Taxation requires electronic filing, and its marketplace guidance states that monthly sales-tax returns are due by the 23rd of the month following the reporting period. The facilitator should use the appropriate seller’s use tax account and report marketplace collections in the manner required by the Department.

Marketplace sellers should not report a facilitator-collected transaction as though they collected the same tax themselves, but they must retain records that support how the sale was handled. Reconcile order data, refunds, exemptions, tax collected, and remittances across channels. Filing frequency and account-specific instructions can change or depend on the Department’s assignment, so check the current Ohio Department of Taxation account notices and filing calendar before each filing.

Meet filing deadlines and avoid penalties

For monthly sales-tax filers, Ohio’s stated due date is the 23rd of the month following the reporting period. File and pay by the applicable due date, including when a return reports no tax if the Department requires a return for that period. A missed or inaccurate return can lead to additional amounts due under Ohio law; the safest approach is to reconcile records early and address discrepancies promptly.

Do not assume every account has the same filing frequency or that a marketplace’s payout schedule determines the state return period. Follow the filing frequency and notices assigned to your Ohio account, and verify current deadlines with the Ohio Department of Taxation. If you discover an error or missed filing, contact the Department or a qualified compliance service to determine the appropriate correction process.

Update or close your Ohio seller’s use tax license

If your business changes ownership, address, sales channels, or tax responsibilities, review the information associated with its Ohio seller’s use tax license and update it through the Ohio Business Gateway or the Department’s current process. A marketplace seller that stops selling through one channel may still have direct sales or other Ohio obligations, so a change in marketplace activity alone does not establish that the account can be closed.

Before closing an account, confirm that all required returns and payments have been handled and that the business no longer has an obligation to collect or remit Ohio tax. Ask the Ohio Department of Taxation how to close or amend the specific account and whether any final return is required. Keep confirmation and supporting records with your tax files.

Ohio rules for delivery network companies

Ohio’s marketplace facilitator definition includes a person that owns, operates, or controls a physical or electronic marketplace through which delivery network services are facilitated for marketplace sellers. A delivery network company can therefore have sales-tax responsibilities for local products sold through its marketplace, as well as tax responsibilities for its own taxable services. The precise treatment depends on the company’s role and the transactions it facilitates.

Ohio law allows a qualifying delivery network company to request a waiver from being treated as the seller of local products sold through its marketplace, subject to statutory conditions and approval by the tax commissioner. A waiver does not remove the company’s seller status for its delivery network services. If a waiver is granted, the company must notify affected local merchants, who may then be responsible for the local product sales as applicable. A delivery network company should confirm current waiver procedures and tax treatment with the Ohio Department of Taxation.

Ohio marketplace sales-tax responsibilities by transaction type

Transaction or activity Ohio sales-tax responsibility to review
Taxable sale facilitated by a marketplace facilitator with substantial nexus The facilitator is treated as the seller for the facilitated sale and is responsible for required collection, filing, and remittance.
Marketplace sale that is exempt under Ohio law Do not collect tax merely because the order used a marketplace; apply Ohio exemption rules and retain supporting documentation.
Seller’s direct sale outside the facilitator’s marketplace The seller must assess its own Ohio nexus and determine whether it must register, collect, file, and remit.
Facilitator’s own sale through its marketplace Include qualifying own sales in the facilitator’s combined economic-nexus analysis and assess taxability and reporting.
Local product sale through a delivery network company The company may be treated as the seller; a qualifying company may request a statutory waiver, subject to approval and conditions.
Delivery network service provided by the company Assess the company’s own service tax treatment separately; a waiver for local products does not remove seller status for the delivery service.
Business activity potentially subject to Ohio CAT Review CAT separately from sales and use tax; marketplace collection does not determine CAT liability.

Frequently asked questions

What is a marketplace facilitator in Ohio?

Ohio defines a marketplace facilitator as a person that owns, operates, or controls a physical or electronic marketplace through which retail sales or delivery network services are facilitated on behalf of one or more marketplace sellers, or an affiliate of such a person. The business’s actual role and activities determine whether the definition applies.

When does a marketplace facilitator have to collect sales tax in Ohio?

A facilitator with substantial nexus that is treated as the seller must collect Ohio tax on taxable retail sales it facilitates, file returns, and remit the tax. Ohio’s Department of Taxation says collection begins prospectively on the first day of the first month that is at least 30 days after substantial nexus is established. Exempt sales remain subject to Ohio’s exemption rules.

What is Ohio’s economic nexus threshold for marketplace facilitators?

Ohio presumes substantial nexus if, in the current or preceding calendar year, the facilitator’s aggregate qualifying Ohio gross receipts exceed $100,000 or it has 200 or more separate qualifying transactions. The calculation includes the facilitator’s own qualifying sales and sales it facilitates for marketplace sellers. Confirm whether particular transactions count under Ohio law.

Do marketplace facilitators need an Ohio seller’s use tax license?

Yes. A facilitator with substantial nexus that is treated as the seller must register for an Ohio seller’s use tax license, collect tax on taxable facilitated sales, file returns, and remit tax. Registration is handled through the Ohio Business Gateway, subject to the Department’s current instructions.

Do Ohio marketplace sellers still need to collect sales tax on direct sales?

They may. A facilitator’s responsibility generally covers sales it facilitates when it is treated as the seller; Ohio law preserves the seller’s responsibility for other sales, including direct sales, when the seller is required to collect and remit. The seller should assess its own nexus, taxability, and registration obligations.

Are marketplace facilitator sales taxable in Ohio?

Taxable retail sales facilitated by a facilitator with substantial nexus are subject to the facilitator’s collection and remittance duties. Not every marketplace transaction is taxable: Ohio exemptions and product- or service-specific rules still apply. Check the Ohio Department of Taxation’s current taxability guidance for the transaction.

How do marketplace facilitators report and remit Ohio sales tax?

A facilitator registers for the appropriate seller’s use tax account, files Ohio returns electronically, and remits tax collected on taxable facilitated sales. The Department’s marketplace guidance states that monthly returns are due by the 23rd of the following month. Follow the filing frequency and account instructions assigned by the Department.

What are Ohio’s marketplace facilitator rules for delivery network companies?

Ohio includes delivery network services in its marketplace facilitator framework, so a company may be treated as the seller for local products sold through its marketplace and has separate responsibilities for its own services. A qualifying delivery network company may request a statutory waiver from seller treatment for local product sales, subject to conditions and approval; the waiver does not remove its seller status for delivery network services.
