I purchased my first vacation rental property last year and titled it to an LLC that I have (let's call it LLC-1) and I also created another LLC (let's call it LLC-2) to market my vacation rental(s). All the income/expenses on the property (mortgage, repairs, any money going in or out) come out of the bank account for LLC-1. I don't have a bank account for LLC-2, yet my hotel occupancy taxes are sent out by AirBNB to the city under the name of LLC-2. Should I be filing a tax return for LLC2 when it is really being used more as a DBA? It seems that since it is an LLC that Uncle Sam will be looking for some sort of tax return for it.
