What Is Form 1099-S?

What is Form 1099-S? It is used to report the sale or exchange of real estate transactions to the IRS.

Are you filing Form 1099-S for the first time? Or are you a seasoned filer who knows the ins and outs of the realm of real estate? Whatever the situation, in this blog, we have the low-down for you on this important tax form.

What Is Form 1099-S?

Basically, Form 1099-S is used to report gross proceeds from the sale or exchange of real property. The transactions could be residential, commercial, timber/mineral rights, foreclosures, exchanges, or barter. 

So, what’s the deal with Form 1099-S? The payer, who is usually the settlement agent or closing attorney, files this form to give the IRS the data it needs to match a seller’s capital-gain reporting. With this form, the IRS can track who’s moving what amount of money around in the property market.

Gross Proceeds vs. Taxable Gain

  • Form 1099-S gross proceeds box 2: This box shows the entire amount paid for the property, like cash at closing, notes, assumed debt, or any other consideration. 
  • Taxable Gain: The seller figures this out later on their personal tax return. They subtract the property’s original cost (basis), improvements, selling expenses, and any allowable exclusions from those gross proceeds. 

Note: Every reportable real estate deal gets a Form 1099-S. There’s no minimum dollar threshold.

Who Must File Form 1099-S?

You could be selling your beach house or closing in on a big commercial complex. Someone has to take charge of real estate proceeds reporting to the IRS. So, who files Form 1099-S?
The person closing the transaction is responsible for filing the form. If no one is responsible for closing the transaction, the person responsible for filing the form is, in the following order:

1. The mortgage lender

2. The transferer’s broker

3. The transferee’s broker

4. The transferee.

Primary filer or the person responsible for closing:

  • It’s usually the title or escrow company, settlement attorney, or any other party that prepares the final Closing Disclosure (HUD-1). 
  • This filer collects the seller’s Form W-9, principal-residence certification (if any), and all settlement documents. 

When there’s no closing agent, the IRS has a backup chain 

  • A mortgage lender that handles payoff funds  
  • Transferor’s real-estate broker (the seller’s agent)  
  • Transferee (buyer) if no one else is involved 

Designation agreement for private or FSBO deals 

The seller and buyer may agree before or at closing to designate one party to file. Most often, it’s the buyer’s attorney. Keep the signed designation with the closing packet in case of an IRS audit and for your peace of mind! 

        Special cases:

  • Foreclosures and Deeds-in-Lieu: The foreclosing lender files. 
  • Section 1031 Exchanges: If there’s cash “boot,” the qualified intermediary takes the lead. 

However, you may designate the person required to file the form in a written agreement. Visit the IRS for more details.

Understanding When to Report and When to Exempt

You don’t have to report every property transaction to the IRS. That’s why it’s crucial you know what entails reportable transaction and exempt transactions. Here’s a simple guide to help you save time, paperwork and stress!
