When it comes to real estate transactions, there’s more to consider than just the sale price and closing date. One of the most important tax documents involved is Form 1099-S, which is commonly issued after the sale or exchange of property. Whether you’re selling a home, land, or commercial space, receiving this form means you’ll need to report the transaction to the IRS.
At Mayatax, we help individuals and business owners handle these filings—whether it’s real estate reporting or sales tax services that keep your business compliant year-round. In this guide, we’ll break down what Form 1099-S is, who’s responsible for filing it, where to report it on your return, and common misconceptions to watch for.
What Is a 1099 S Form?
Form 1099-S, titled Proceeds from Real Estate Transactions, is an IRS information return used to report the sale or exchange of real estate. This form helps the IRS track ownership changes that may result in taxable gains or losses, even if the transaction itself isn’t immediately taxable. You might receive a 1099-S regardless of whether you made a profit, as long as the transaction is considered reportable under federal tax rules.
A 1099-S must be filed when there is a transfer of any present or future ownership interest—such as fee simple, life estate, remainder interest, or a long-term leasehold (30 years or more)—in real property, which includes:
- Improved or unimproved land (including air rights)
- Residential, commercial, or industrial buildings (inherently permanent structures)
- Condominium units and related common areas
- Stock in a cooperative housing corporation
- Non-contingent interests in standing timber
The sale or exchange may involve money, debt forgiveness, property, or services. Even certain nontaxable exchanges, like transfers to a corporation under Section 351 or sales of a main home with an excluded gain, may still require a 1099-S filing.
The form also applies in unique cases such as:
- Sales through land contracts (reported in the year the contract is executed)
- Involuntary conversions due to threats of seizure or condemnation
- Contractual timber sales for fixed lump-sum payments
Who Issues Form 1099-S?
Form 1099-S is typically filed by the person responsible for closing the real estate transaction—usually the settlement agent listed on the Closing Disclosure. This may be a title company, escrow agent, attorney, or broker.
If no settlement agent is listed, responsibility falls in the following order:
- Transferee’s attorney
- Transferor’s attorney
- Title or escrow company disbursing the funds
If none of the above apply, the filer may be:
- The mortgage lender
- The transferor’s broker
- The transferee’s broker
- The transferee (buyer)
Parties can also enter a written agreement to designate one person to file. Only one Form 1099-S should be filed per transferor.
Where to Report Form 1099 S
The amount shown in Box 2 of the form (gross proceeds from the sale) must be reported on your federal tax return. Most taxpayers report this on Schedule D (Form 1040) for capital gains and Form 8949 to list the property details and calculate any gain or loss. You’ll also need to determine your cost basis to accurately report the profit or loss from the sale.
Form 1099 S Instructions: What You Need to Know
IRS Form 1099-S reports proceeds from real estate transactions. Each section of the form provides key information for both taxpayers and the IRS. Here’s what each part means:
- Transferor’s Taxpayer Identification Number (TIN)
What it is: Only the last four digits of your SSN, ITIN, ATIN, or EIN may appear on the form for security.
Why it matters: The full TIN is already reported to the IRS for accurate record matching. Make sure the TIN on file is correct to avoid processing delays. - Account Number
What it is: A unique number that may be assigned by the filer to identify your account.
Why it matters: Helps track the transaction, especially if multiple properties or sales are involved. - Box 1 – Date of Closing
What it is: This box shows the official closing date of the real estate sale.
Why it matters: This date determines the tax year in which the transaction must be reported. - Box 2 – Gross Proceeds
What it is: Displays the total amount you received from the sale, including cash, notes payable, and debts assumed or paid off by the buyer.
Why it matters: This figure is central to calculating potential capital gains or losses on the transaction. - Box 3 – Property Description
What it is: Lists the physical address or legal description of the property sold.
Why it matters: Identifies the specific property involved in the sale for your records and IRS verification. - Box 4 – Property or Services Received
What it is: If checked, it means you received something other than cash or notes (like services or goods) in the sale.
Why it matters: These items are not included in Box 2 but may still have tax implications. - Box 5 – Foreign Status
What it is: This box is checked if the seller is a foreign person or entity.
Why it matters: Foreign sellers may be subject to special IRS withholding requirements under FIRPTA. - Box 6 – Real Estate Tax Allocated to Buyer
What it is: Shows any portion of real estate taxes that were charged to the buyer at settlement.
Why it matters: If you already paid the full year’s tax, this amount may reduce your deductible real estate tax—or require reporting as income if previously deducted.
How to File Form 1099-S
If you’re responsible for filing, here’s how to handle it correctly:
- Complete the form with the seller’s name, address, TIN, property description, and gross proceeds.
- Send Copy A to the IRS. If filing by paper, include Form 1096 as a cover page. To file electronically, submit the form through the IRS FIRE system.
- Provide Copy B to the seller by January 31 to comply with IRS delivery requirements.
If you’re unsure about filing correctly, our professional Tax Services can handle everything on your behalf—from document preparation to secure submission.
Do You Always Owe Taxes When You Receive a 1099-S?
Not always. A 1099-S simply reports a real estate transaction to the IRS—it doesn’t automatically mean you owe taxes.
If you sold your primary residence and meet the requirements of IRS Section 121, you may exclude up to $250,000 of gain if single or $500,000 if married filing jointly. In this case, even if you receive a 1099-S, the gain may be fully tax-free.
To avoid the 1099-S altogether, the closing agent must receive a signed certification from the seller stating:
- The property was your principal residence,
- The full gain is excludable under Section 121,
- The property has not been used for nonqualified purposes after December 31, 2008.
If you don’t provide the certification, a 1099-S must be issued—even if you qualify for the exclusion. Just be sure to keep the certification for four years and report the sale properly when filing your taxes.
