Who Issues a 1099-S? Settlement Agents, Designation, and Exceptions

In almost every real estate closing, the person who issues Form 1099-S is the settlement agent named on the Closing Disclosure — the title company, escrow agent, or closing attorney who handles the transaction. Federal law under 26 U.S.C. § 6045(e) makes that person the “real estate reporting person,” and the duty only shifts elsewhere when no such agent exists.¹

The Default Filer: The Settlement Agent

If a Closing Disclosure is used and it names a settlement agent, that agent is the reporting person. No analysis, no hierarchy, no discretion.² If no Closing Disclosure is used, or none names a settlement agent, the reporting person is whoever prepared a closing statement that identifies the buyer and seller, describes the property, and shows how proceeds were distributed.³

For a typical residential or commercial sale, that is the whole answer. A title company or closing attorney is running the settlement, and they file. Sellers and buyers do not.

The Fallback Hierarchy When No Closing Agent Exists

The rest of the statute matters when a sale happens without a formal settlement — think of a direct sale between neighbors, an owner-financed deal, or a family transfer with no title company involved. In that situation, responsibility falls to the next person on this list, in order:¹

The mortgage lender providing new financing secured by the property. If more than one lender is involved, the one advancing the most funds takes the duty.
The seller’s broker — the agent under contract with the seller and being paid on the transaction.
The buyer’s broker — the agent who played the largest role in preparing or presenting the offer.
The buyer, meaning the person acquiring the greatest interest in the property. If that is not clear, it is whoever appears first on the deed or transfer documents.

The buyer’s slot at the end matters more than it looks. In a private cash sale with no title company, no new lender, and no agents, the filing obligation lands on the buyer by default. Many buyers in that situation never realize they are the reporting person until the IRS asks why no form was filed.

Shifting the Duty by Written Designation Agreement

The parties can reassign the 1099-S filing obligation through a written designation agreement, and the IRS lets you include that agreement directly on the Closing Disclosure. The only limit is that the person taking on the duty must be someone who would already qualify as a reporting person somewhere in the hierarchy.³

The agreement has to include the name and address of the person accepting the filing duty, the names and addresses of everyone signing, identifying information for the buyer and seller, and a description of the property. Every party signs and dates it, and each signer keeps a copy for four years.³

When the Filer Can Skip the Form

Being the reporting person does not always mean issuing a 1099-S. Several transactions are outside the requirement, and the most common one comes up in ordinary home sales.

The Principal Residence Exception

The reporting person may skip the 1099-S when gross proceeds are $250,000 or less for a single seller, or $500,000 or less when the seller certifies they are married — but only if both conditions are met.³ The seller must also provide a written certification stating that the home was their principal residence, that the full gain qualifies for exclusion under Section 121, and that they have not used the exclusion on another home sale in the prior two years.

Two cautions. First, this exception only relieves the closing agent from filing; it does not change whether the seller has to report the sale on their own return. Second, if gross proceeds exceed the threshold — even by a dollar, and even if the taxable gain is zero — the exception is gone and the form must be filed.

Exempt Sellers

Some sellers are exempt regardless of the sale price. No 1099-S is issued when the seller is a corporation (including associations, joint-stock companies, insurance companies, and publicly traded partnerships) or a government entity at any level — federal, state, local, foreign, or an international organization.³

There is also an exemption for high-volume real estate dealers — sellers who sold or expect to sell at least 25 separate properties to at least 25 separate buyers in the current year or either of the two preceding years, where each property was held for sale to customers in the ordinary course of business. To claim it, the seller signs a certification under penalties of perjury and gives it to the closing agent.³

Transfers That Are Not Sales

Gifts, inheritances, and involuntary conversions such as condemnation proceedings do not require a 1099-S. One boundary worth flagging: when a foreign person sells U.S. real property, the closing agent still files a 1099-S. FIRPTA withholding on Form 8288 is a separate obligation of the buyer and does not replace the reporting person’s filing.²

What the Filer Needs From the Seller

To complete the form, the reporting person needs the seller’s full legal name, mailing address, and taxpayer identification number, along with the closing date, gross proceeds, and property description.⁴ Gross proceeds means the full contract price before commissions and closing costs, and it includes the fair market value of any non-cash property the seller received.

The TIN is where transactions get tense. If a seller refuses or fails to provide one, the reporting person must begin backup withholding at 24% of the gross proceeds and remit that money to the IRS, reporting it on Form 945.⁵ Sellers who try to sidestep reporting by withholding their Social Security number lose nearly a quarter of their proceeds to withholding instead of avoiding anything.

Deadlines the Filer Must Meet

The reporting person faces two deadlines. The seller’s copy must be furnished by February 17, 2026 for the 2025 tax year — handed over at closing or mailed by that date. The IRS copy is due February 28 on paper or March 31 electronically.⁶ Paper filers include Form 1096 as a transmittal cover.⁷ Anyone filing 10 or more information returns of any type during the year generally must file electronically.

Missing either deadline carries per-form penalties under 26 U.S.C. § 6721, tiered by how quickly the filing is corrected, with the top tier reserved for returns never filed or corrected after August 1. Intentional disregard carries a higher minimum penalty and no annual cap.⁸ Penalties apply separately for the failure to file with the IRS and the failure to furnish the form to the seller, so one missed 1099-S can generate two hits.
