Ohio hasn't published a clear answer on whether a marketplace-only seller must register.

The Bottom Line for Ohio eBay Sellers

Ohio is one of the harder states in this cluster to give a confident answer on for one specific question, whether a seller with no non-marketplace Ohio sales has to register at all, and this page says so rather than filling the gap with a guess. What Ohio does answer clearly is its Commercial Activity Tax, which carries an exclusion high enough that the overwhelming majority of individual eBay sellers never approach it.

Ohio's tax code shifts the collection duty for marketplace-facilitated sales onto the facilitator, and the one Department of Taxation guidance document addressing this directly is written for a seller who also sells through a personal website and a catalog, not for someone whose only channel is eBay. That document explains the seller's own registration threshold and confirms marketplace sales count toward it, but it never actually says whether a marketplace-only seller, with nothing left to collect on once facilitated sales are excluded, still has to file a return. Rather than resolve that gap with an inference dressed up as a fact, this page leaves it open and points you to Ohio's own current guidance to check directly. The Commercial Activity Tax question is a separate, better-answered one: its exclusion amount sits well above what most individual resellers generate from Ohio-sourced receipts alone.

We could not confirm Ohio's position on whether a marketplace-only seller must register. Your eBay sales count toward Ohio's $100,000 or 200 transactions threshold, so marketplace volume alone can push you over it. Ohio uses the federal reporting threshold, so eBay issues a 1099-K once you pass $20,000 and 200 transactions.

eBay Collects Ohio Sales Tax. What Is Still Yours?

We could not confirm Ohio's position on whether a marketplace-only seller must register.

Here is the honest state of Ohio's own guidance: a 2019 Department of Taxation tax alert answers a mixed-channel seller's question directly, stating that combined sales into Ohio, including marketplace-facilitated sales, determine whether the seller crosses Ohio's registration threshold, and that the seller is only obligated to actually collect and remit on the non-marketplace portion of those sales. What that alert doesn't say is whether a seller with zero non-marketplace Ohio sales, who would have nothing left to collect on even after registering, is required to register in the first place. Ohio's current live guidance page addressing this more specifically loads its content in a way this research couldn't retrieve, so this page isn't going to assert an answer it can't back up. If this question matters to your situation, check Ohio's current FAQ directly or ask the Department, rather than relying on an inference from a document written for a different fact pattern.

Do Your eBay Sales Count Toward Ohio's Nexus Test?

Your eBay sales count toward Ohio's $100,000 or 200 transactions threshold, so marketplace volume alone can push you over it.

Where Ohio is clear: its substantial-nexus threshold is set on either a gross-receipts figure or a transaction count, either one sufficient on its own, and the 2019 tax alert states plainly that marketplace-facilitated sales combine with any direct sales to determine whether a seller crosses that threshold, even though the seller only collects on the non-marketplace portion once registered. That means your eBay volume is relevant to the threshold calculation regardless of the open registration question above. If you run a second Ohio-facing channel alongside eBay, both channels' totals count toward the same combined figure, and only the non-marketplace channel is ever yours to collect and remit on directly.

Ohio's 1099-K Threshold

Ohio uses the federal reporting threshold, so eBay issues a 1099-K once you pass $20,000 and 200 transactions.

Ohio's information-return system is triggered by state income tax withholding, not by a payment or transaction figure, and its own upload specifications for 1099 filings state directly that a form isn't required to be submitted to the Department if no Ohio individual income tax was withheld from the payment. An eBay payout doesn't involve Ohio withholding, and no separate Ohio guidance addressing Form 1099-K specifically as its own category was found. Ohio's filing system appears not to reach 1099-K on any independent threshold basis. That has no bearing on what you owe on the underlying income; it only affects where a copy of federal paperwork does or doesn't land with the state.

Buying Inventory to Resell in Ohio

Ohio accepts the Multistate Tax Commission's uniform certificate, but not every out-of-state form.

Ohio's Department of Taxation guidance affirmatively states the Multistate Tax Commission (MTC) Uniform Sales and Use Tax Certificate is 'Accepted by Ohio for resale and for purchases of items incorporated into products for sale.' Ohio's own administrative rule on exemption certificates (OAC 5703-9-03) lists a purchaser's Ohio vendor's license/use-tax account number as a data element to include only 'if any,' meaning an Ohio-issued ID is not mandatory for every valid exemption claim -- consistent with accepting the MTC certificate from an out-of-state reseller without Ohio registration. Ohio's own Form STEC-B/STEC-U are the state's native blanket/unit exemption certificates for in-state use.

Ohio's Department of Taxation affirmatively lists the Multistate Tax Commission's uniform certificate as accepted for resale purchases, and Ohio's own administrative rule treats an Ohio-issued tax ID as an optional data element rather than a mandatory one on a valid exemption certificate, consistent with accepting an out-of-state reseller's MTC certificate without requiring separate Ohio registration first. Ohio's secondhand-goods statutes reach only pawnbrokers and precious-metals dealers by name; no statewide statute licensing general resale of ordinary used goods was located, though this page can't rule out a local ordinance in your specific city the way it could confirm one exists elsewhere, since Ohio's municipal code resources weren't reachable this session.

Ohio has no statewide second-hand dealer licence reaching general resale. The two Ohio Revised Code chapters that regulate used-goods-adjacent trades are both carve-outs under the brief's scoping rule: ORC Chapter 4727 licenses pawnbrokers ('a person engaged in the business of lending money on deposit or pledges of personal property'), administered by the Superintendent of Financial Institutions; ORC Chapter 4728 licenses precious metals dealers ('purchasing articles made of or containing gold, silver, platinum, or other precious metals or jewels') and by its own terms 'does not cover general resale of ordinary used goods.' No Ohio Revised Code chapter was located that imposes a statewide license on general secondhand resale by an ordinary online reseller.

The Ohio Tax eBay Does Not Handle

Ohio levies Commercial Activity Tax, which can still reach you even though eBay handles the sales tax: Ohio's CAT reaches an out-of-state, marketplace-only seller only if the seller's own taxable gross receipts sitused to Ohio exceed the annual exclusion amount, which is $6,000,000 for 2025 and thereafter (was $3,000,000 for 2024, and $150,000 before that) per R.C. 5751.01(R): "'Exclusion amount' means three million dollars beginning in 2024 and six million dollars beginning in 2025." Separately, a remote seller has 'bright-line presence' (CAT nexus) without any physical presence in Ohio if it has at least $500,000 of Ohio taxable gross receipts in the calendar year (R.C. 5751.01(I)) -- but nexus alone does not create a filing/payment obligation; only receipts above the $6M exclusion amount do. For the great majority of individual marketplace-only eBay sellers (well under $6M in Ohio-sourced receipts), no CAT registration or payment obligation arises, even though they have 'nexus' in the technical sense.

Setting Up to Sell on eBay from Ohio

1. Confirm Ohio's current registration answer directly with the Department

   This page couldn't locate a published statement addressing a marketplace-only seller's registration duty specifically. Don't rely on an inference from guidance written for a mixed-channel seller.

2. Form the LLC regardless of how the registration question resolves

   The liability protection an LLC provides doesn't depend on Ohio's answer to the open registration question, and it's cheaper to put in place before your volume grows.

3. Check your Ohio-sourced receipts against the Commercial Activity Tax exclusion

   Ohio's exclusion amount sits well above what most individual eBay sellers generate. Confirm where you actually stand rather than assuming either way.

4. Use the MTC uniform certificate for wholesale purchases

   Ohio accepts the Multistate Tax Commission's certificate for resale purchases without requiring separate Ohio registration first.

5. Revisit registration if you add a non-marketplace Ohio sales channel

   Ohio's own guidance is clear that a direct-sales channel creates its own collection duty, resolving at least part of the open question above.

Who to Ask in Ohio

The Ohio Department of Taxation handles Commercial Activity Tax registration and sales tax questions, and its current FAQ pages are worth checking directly for the registration question this page couldn't fully resolve. The Ohio Secretary of State's office forms and maintains your LLC as a separate filing from anything Taxation tracks. For secondhand-dealer questions, check with the city where your business is based, since Ohio's home-rule structure generally leaves that kind of licensing to individual municipalities.

Federal 1099-K threshold: IRC § 6050W(e), as amended by § 70432(a) of the One, Big, Beautiful Bill Act (P.L. 119-21, July 4, 2025). A third-party settlement organization such as eBay must file Form 1099-K only if BOTH tests are met for the calendar year: gross payments exceed $20,000 AND the number of transactions exceeds 200. These are the figures for tax year 2026. There is no forward phase-in: § 70432(a) takes effect "as if included in section 9674 of the American Rescue Plan Act," so the same $20,000 / 200 figures apply retroactively to calendar years after 2021 (tax years 2022 through 2026 alike). The $600 threshold enacted by ARPA § 9674 (P.L. 117-2) was repealed before it operated, and the IRS transition-relief thresholds previously announced for 2024 and 2025 are superseded. A platform may issue a 1099-K below these figures, and a state may set a lower TPSO threshold, in which case a seller can receive a 1099-K without meeting the federal test.. Verified 2026-08-08.
