Who Sends a 1099-S When You Sell a House?

When you sell a house, the closing agent handling your transaction is the party responsible for sending Form 1099-S to you and to the IRS. In most sales that means the title company, escrow officer, or closing attorney who disburses the funds at closing. They file the form with the IRS and mail or deliver your copy. You do not request it, and the buyer does not send it in a typical closing.

Who Files When There Is No Closing Agent

Not every sale runs through a title company or attorney. When no one is formally acting as the closing agent, the filing duty falls through a set order: first to the mortgage lender providing new financing to the buyer, then to the seller’s real estate broker, then to the buyer’s broker, and finally to the buyer.¹ The parties can also sign a written designation agreement at or before closing that assigns the filing duty to any party already in that chain.

For-Sale-By-Owner Sales

If you sell privately with no agents and no title company, someone in the chain still has to file. If the buyer takes out a mortgage, the lender files. If there is no lender and no brokers on either side, the buyer becomes the filing party by default.¹ Most buyers in that position do not know this, which is one reason private sales often produce missing 1099-S forms and IRS follow-up letters months later.

When You Won’t Receive a 1099-S at All

Many primary-residence sales are exempt from 1099-S reporting entirely, and the exemption does not depend on the sale price. It depends on whether your entire gain is excludable under the Section 121 home sale exclusion. A house that sells for $800,000 can be exempt as long as the gain falls within the exclusion limits.²

To trigger the exemption, you have to give the closing agent a written certification, signed under penalty of perjury, stating two things: the property is your principal residence, and the full gain from the sale is excludable under Section 121. The closing agent has to keep that certification for four years. If there are multiple owners, each owner has to provide a separate certification, or the closing agent must file a 1099-S for anyone who does not certify.

Other exempt transactions include transfers to corporations or government entities, sales where the total consideration is under $600, and transfers that are not treated as sales or exchanges at all, such as gifts or inheritances.

One point catches sellers off guard: the closing agent’s decision not to issue a 1099-S does not relieve you of reporting the sale on your own return if you have a taxable gain. You owe the tax whether or not a form was ever filed.

When You Should Expect the Form

The closing agent has to furnish your copy of the 1099-S by January 31 of the year after the sale. The form is due to the IRS by February 28 on paper, or March 31 electronically.³ Any filer submitting 10 or more information returns in a calendar year has to file electronically.⁴ If you closed the year before and haven’t seen anything by early February, contact the title company or attorney who handled the closing.

Watch for Backup Withholding

If you fail to give the closing agent your taxpayer identification number, usually your Social Security number, they are required to withhold 24% of the gross proceeds and send it to the IRS as backup withholding.³ You get credit for the withheld amount when you file your return and claim it, but the cash is tied up in the meantime. Sign the closing agent’s request for your TIN carefully so this does not happen by accident.

What the 1099-S Actually Reports

Form 1099-S, Proceeds From Real Estate Transactions, tells the IRS that a property changed hands and how much the seller received. It shows the closing date, the gross proceeds, and basic information about the property and parties. It does not show your profit or loss. Only the total you received or were credited at closing.

Gross proceeds include cash paid to you, the outstanding balance of any mortgage the buyer assumed, and the principal amount of any promissory note you took back. If you received property or services as part of the deal, the closing agent checks a separate box on the form rather than assigning a dollar value.⁵ The IRS compares the gross proceeds on your 1099-S with the sale price on your return, and mismatches tend to generate letters.

Reporting the Sale on Your Return

You report a home sale on Form 8949, Sales and Other Dispositions of Capital Assets, which flows into Schedule D of your Form 1040.⁶ This is where the IRS reconciles the gross proceeds shown on any 1099-S with the gain or loss you calculate.

There is one narrow situation where you can skip the reporting step. If your full gain qualifies for the Section 121 exclusion and no 1099-S was issued, you are not required to report the sale at all. If a 1099-S was issued, though, you still have to report it on Form 8949, even if the entire gain is excluded. Otherwise the IRS has no way to match its copy of the 1099-S to your return, and you can expect a notice.

Keep Records Even Without a Form

The IRS can assess an accuracy-related penalty of 20% of any underpaid tax if it decides you were negligent in calculating or reporting your gain. That penalty doubles to 40% for a gross valuation misstatement, such as substantially inflating your basis to shrink the gain.⁷ Records of your purchase price, capital improvements over the years, and any depreciation you claimed are the simplest protection against both the penalty and the audit that produces it.

Foreign Sellers Are a Different System

If the seller is a foreign person or entity, a separate reporting layer applies alongside the 1099-S. Under the Foreign Investment in Real Property Tax Act, or FIRPTA, the buyer must withhold 15% of the total sale price and send it to the IRS using Form 8288, which is due within 20 days of closing.⁸ The buyer is the withholding agent, not the closing company, though the title company usually handles the mechanics in practice.

A foreign seller can apply for a withholding certificate on Form 8288-B before closing to reduce the withholding to the actual expected tax, which is often less than 15% of the gross price. Even with an application pending, though, the buyer still has to withhold the full amount at closing and hold it until the IRS responds.⁹ FIRPTA withholding is a separate obligation from the 1099-S. A foreign seller’s transaction can trigger both.

If the Form Never Arrives

If you were expecting a 1099-S and February passes without one, start with the closing agent listed on your settlement statement. They can confirm whether they filed, whether you signed a Section 121 certification that exempted the sale, or whether the form was sent to an old address. If the closing agent misses the deadline or files incorrect information, the IRS imposes per-return penalties on them that scale with how late the fix happens, up to $340 per return, or $680 for intentional disregard, for returns due in 2026.¹⁰ Those penalties fall on the filer, not on you. Your obligation is to report any taxable gain correctly on your own return, with or without the form in hand.
