Hi Paula,
I just saw your post. I'm not an attorney or CPA, but I did a search on the IRS website (with the help of ChatGPT) and it appears that if the charitable organization pays you, the landlord, directly for that portion of the rent subsidy, they are probably required to issue a 1099-MISC to you at the end of the year. As such, they would require you to complete a W-9.
Here are the references:
Situation: Charitable organization pays $600+ rent directly to landlord on behalf of tenant
Form 1099-MISC Required? Yes
Relevant Code / Regulation - IRC § 6041(a); Treas. Reg. § 1.6041-1(a)(1)(i)(B); PLR-143055-09 precedent
You might check with Don McCartney, I'm sure he could answer your question.
Thanks,
Terry
