Hi Sandra,
I am also a property owner with several Michigan properties on Air bnb. I see that the tax was withheld begining in July, however, have found no evidence whatsoever that they "remitted" this tax. I called the Michigan Department of Treasury and found that nothing has been "remitted" by air bnb on our behalf. I have been receiving Bills from the Treasury department begining in Febuary, one by one, starting with July, because this is when I began to forgo the tax on the aribnb rentals and mail in our other income from our rentals. I further found out that I not only owe the money that they claimed to have charged and sent in, but also a lot of penalty interest-charged by the day, from July thru now. I have called Air bnb about the sales tax issues several times, with no help whatsoever. The last time I called I actually BEGGED someone to please transfer me to someone that knew anything about the Michigan Sales tax, to which nobody knew anything at all! This by far has been the most stressful part of Airbnb, announcing they are taking care of it and then having no information at all. Our accountant is now on it as well (at $75/hr). There is a huge disconnect from Airbnb on this, if you have found any information at all, I would be so happy to hear what you found out! Thank you, Angie
