@Alfonso248 Yes, the tax information is available for your account at the end of the year. They don't "send " anything, you'll find it on the site. As far as a business license for the Airbnb, business licenses in Mexico are administered by the municipalities, rather than being a federal thing, so it could vary from state to state and municipality. Your best bet is to find a well-recommended Mexican accountant in the area where your listing is who can advise you on all you need to do to legally comply. You may be able to actually do it all yourself, but the accountant can give you a clear picture of all the requirements.
I run a business here, aside from my little private-room Airbnb. What I found was that Hacienda, the Mexican federal tax entity, doesn't have any interest in whether you have a business license or not- they've never asked to see it. All they care about is that you report your earnings and pay the applicable taxes. However, the municipality could send people around to check whether someone has a business license or not.
And as you're a dual citizen, you likely know that sometimes things can be "bent" a little in Mexico. As my daughter, who also lives in Mexico, says-" Mexico- where nothing is allowed, yet everything is allowed" 🙂
