Kentucky sellers: how to report Stonefjord sales on your own return
Stonefjord already collects and pays Kentucky sales tax on your sales here. Report them as gross receipts, then deduct them — so you are not taxed twice.
What Stonefjord already does
Since 25 August 2026, Stonefjord is a registered Kentucky marketplace provider. On taxable Kentucky sales made through Stonefjord, we calculate the sales tax, collect it from the buyer at checkout, and pay it to the Department of Revenue. You do not collect it, and you should not remit it again.
You still report the sales
Kentucky asks marketplace sellers to include their marketplace sales in total gross receipts on Line 1 of the Sales and Use Tax Return (Form 51A102, or its equivalent in MyTaxes) for each reporting period. This is a reporting step, not a payment step — the deduction below cancels it out.
Then deduct them as an "Other" deduction
On the deductions worksheet, deduct the same amount under "Other" deductions. Kentucky DOR confirmed the mechanics directly on 8 September 2026: you "show your sales and then deduct them back out using the 'other' deduction and type 'Stonefjord' as the reason." Give the full notation so your return stands on its own: "Stonefjord — sales facilitated by marketplace provider Stonefjord LLC, KY sales tax account 680273579." DOR's published marketplace FAQ asks for the provider's name and account number, so include the number even though the reason field alone would satisfy the wording DOR gave us — your accountant will ask for it. The net effect is no double tax: the sales appear on your return, and the tax on them is not charged to you again.
Where to find your figures
Your Stonefjord sales for any period are in your seller dashboard. Use the gross amount buyers paid for the items, before Stonefjord fees — a marketplace deduction is about the sale, not about what you netted. If a sale was refunded inside the same reporting period, Kentucky DOR told us on 8 September 2026 to "report your sales and if there are returns/refunds issued in the same period, you would deduct those back out" — so report it and deduct it, rather than leaving it off.
Where Stonefjord collects, and where this is written down
Kentucky is currently the only place Stonefjord collects transaction tax. The live list, with the date collection began in each jurisdiction, is published at Where Stonefjord collects tax (/tax-jurisdictions) — that page is the authoritative list, and Stonefjord commits there to at least 30 days' notice before adding a jurisdiction. The rule itself is Section 7, Taxes, of the Terms of Service: subsection (a) covers what Stonefjord collects, and subsection (b) is the no-double-collection rule this article walks you through.
Tax-exempt buyers
Stonefjord does not accept resale or exemption certificates at checkout and cannot process a tax-exempt purchase. A buyer who holds a valid exemption can contact support within 90 days of the sale; Stonefjord may, but is not obliged to, refund the tax once it has a fully completed certificate. In Kentucky the refund has to run this way round — the marketplace provider claims it from the Department of Revenue only after refunding the buyer, so there is no separate claim for the buyer to make. This is Section 7, Taxes, subsection (f) of the Terms.
What this does not cover
This is about Kentucky sales tax on sales made through Stonefjord. It does not change your income tax, your business licence, or any local or occupational tax, and it does not apply to sales you make outside Stonefjord. Stonefjord does not give tax advice — check with your own accountant about your situation.
