Believe me, they don't always. I've done about 500 closings and 90% of them my title agent said quote "We will not report this to the IRS. It is your responsibility to do that."
I've NEVER received any IRS tax paperwork at closing or even at the end of the year. I've always had to give my accountant numbers off of my HUD-1's, but I've never received anything from the title company. I do remember that a couple times when I closed with different title companies that I had to sign an IRS form, and they said they were going to report it, but they did not give or send me a 1099 or any other IRS paperwork.
Again, I have NEVER received a 1099 or any other IRS paperwork from the title company.
1099's are for reporting payments to NON-corporations except for payments for legal advice. If you are buying or selling in a corporate entity then you aren't going to get a 1099.
Again, checking with your title company/agent and/or accountant is your best bet.
