I've seen landlords live in blissful ignorance for 5-10 years due to dumb luck, then their world comes crashing down and they lose everything.I have a book, there are some in the BP bookstore, or you can check out one of my personal favorites, Every Landlord's Legal Guide by NOLO.

Even if they do not, it’s not your legal responsibility.Long version: It actually depends on your method of payment, and it’s not always clear.Credit card payments: clearly not you problem, no 1099s needed.Zelle payments: you DO need to send 1099s for Zelle payments.PayPal, Venmo and Cash App payments: this is where it gets tricky.
