Form 1099-S reports proceeds from real estate sales and exchanges. When it comes to real estate transactions, the hard part is determining when a closing actually becomes a reportable 1099-S transaction.
This guide explains Form 1099-S instructions in detail, including when a real estate transaction is reportable, who is responsible for filing Form 1099-S, and how to complete the form.
What Is Form 1099-S?
Form 1099-S is used for reporting the sale or exchange of real estate to both the IRS and the transferor. The transferor is usually the seller or the person giving up an ownership interest in the property.
The form can apply to a wide range of properties, including:
- Residential property
- Commercial or industrial buildings
- Unimproved land
- Condominium units
- Cooperative housing stock
- Inherently permanent structures
- Certain standing timber interests
- Long-term ownership interests, such as certain leaseholds, easements, or timeshares with at least 30 years remaining, including renewal periods
One aspect that can confuse people is that Form 1099-S reports gross proceeds, not taxable gain. For example, a main home sale may still be reportable even if the seller can exclude the gain, unless an exception applies. Beginning with 2026 returns, digital assets received in a real estate sale or exchange may also be reported on Form 1099-S.
Who Must File Form 1099-S?
In most cases, the person responsible for closing the transaction files Form 1099-S. This is usually the settlement agent listed on the Closing Disclosure or settlement statement.
If there is no closing person, the filing responsibility moves in this order: mortgage lender, transferor’s broker, transferee’s broker, then transferee.
The parties can also use a written designation agreement at or before closing to name who will file.
1099-S Instructions by Closing Scenario
Use this table to decide whether the transaction is usually reportable before you prepare Form 1099-S:
| Closing scenario | Is Form 1099-S usually required? | Filing note |
|---|---|---|
| Commercial building sale | Yes | Report the gross proceeds, not the seller’s gain |
| Vacant or raw land sale | Yes | Land without improvements still triggers reporting |
| Primary home sale | Depends | Not required if the seller gives an acceptable certification and the sale meets the main home exception |
| Condo unit sale | Yes | The condo unit, fixtures, common elements, and land can count |
| Co-op share sale | Yes | Stock in a cooperative housing corporation can be reportable |
| Land contract/contract for deed | Yes | Report it in the year the parties enter into the contract |
| Property transferred by gift or bequest | No | Neither one is a sale or exchange |
| Refinance with no sale | No | Pure financing or refinancing stays off the form |
| Transfer with total consideration clearly under $600 | No | Form 1099-S is generally not required if the total value of money, services, and property is clearly less than $600 |
| Digital assets received in the real estate deal | Yes, from 2026 on | Report the digital asset gross proceeds in U.S. dollars and include the required digital asset information |
What Counts as Reportable Real Estate for Form 1099-S?
Form 1099-S generally covers sales or exchanges of present or future ownership interests in real estate. That includes improved or unimproved land (including air space), residential, commercial, or industrial buildings, condominium units, cooperative housing stock, and non-contingent interests in standing timber.
The ownership interest is not limited to full ownership of the property. Life estates, remainder interests, reversions, perpetual easements, and certain long-term leaseholds, easements, or timeshares can also qualify, so the reporting decision should be made before closing. It frequently depends on the type of interest being transferred, not just on the sale price.
Common 1099-S Exceptions
There are some real estate transactions that do not need a Form 1099-S to be filed. Some such common exceptions are:
- Certain principal residence sales when the seller gives the required written certification and the sale qualifies for the Form 1099-S exception
- Transactions that are gifts or bequests
- Refinancing that is not connected to acquiring real estate
- Transfers that are not sales or exchanges
- De minimis transfers where the total money, services, and property are clearly less than $600
- Certain exempt volume transferor transactions, if the required exempt-status certification is received
- Sales of unaffixed manufactured homes or mobile homes that are not connected to a sale or exchange of reportable real estate
Key Form 1099-S Boxes

Step-by-Step 1099-S Filing Instructions
Step 1: Get the transferor details
Start with the transferor’s legal name, address, and TIN. If the sale has more than one transferor, each transferor usually needs a separate Form 1099-S.
Step 2: Confirm whether Form 1099-S is required or not
Before filling out the form, confirm that the transaction is a reportable real estate sale or exchange. Some closings do not need Form 1099-S.
Step 3: Check whether an exception applies
A filing may not be necessary if a transaction falls under an IRS exception. For example, you may not need to file Form 1099-S for a qualifying principal residence sale with the required seller certification, certain small transfers, gifts or bequests, financing or refinancing not tied to buying real estate, or transfers made in full or partial satisfaction of debt.
Step 4: Work out the gross proceeds
Use the full gross proceeds from the sale, generally the sales price. Do not subtract commissions, legal fees, or other selling costs.
Step 5: Add the transaction details
Complete all the boxes with required data closing date, gross proceeds, property information, buyer’s share of real estate tax, and any required checkboxes. For 2026 transactions involving digital assets, also fill in the required digital asset details.
Step 6: Send the transferor copy and file with the IRS
After reviewing the form, give the transferor their copy by the due date. Then submit Copy A to the IRS by the paper or eFile deadline.
Note: If your 2026 total information return count is 10 or more, you’ll have to eFile through IRIS, unless the IRS has approved a paper-filing waiver.

OBBBA Update: Does It Change Form 1099-S?
The One Big Beautiful Bill Act (OBBBA) changes several reporting rules, including raising the threshold for certain Form 1099-MISC and Form 1099-NEC payments to $2,000 for tax years beginning after 2025 and keeping the Form 1099-K TPSO threshold at over $20,000 and over 200 transactions.
However, there are not too many changes for Form 1099-S. The basic Form 1099-S rules for real estate closings still apply. The main 2026 update is that digital assets received in a real estate sale or exchange may also be reported on the form.

FAQs
1. Is every real estate closing reported on Form 1099-S?
No, not every real estate closing has to be reported. Some transactions are not reportable, like certain certified principal residence sales, gifts, bequests, refinances that are not tied to buying real estate, transfers made in full or partial satisfaction of debt, and clearly under-$600 transfers.
2. When is Form 1099-S due?
For 2026 returns, recipient copies are due February 15, 2027, paper IRS filing is due March 1, 2027, and eFiling is due March 31, 2027.
3. Do I need a separate Form 1099-S for each transferor?
Generally, yes. File one Form 1099-S for each transferor. If the only transferors are spouses, you can report both spouses on one form, unless they give you a clear split of the gross proceeds. In that case, file one form for each spouse using that split.
Keep Form 1099-S filing simple. Enter the transaction details, eFile with the IRS, and send transferor copies through 1099Online.
