Yes, airbnb will be collecting a service fee on the 10.75%, but more importantly, you will be taxed 10.75% of that 10.75% because you have it in the gross amount! You must do a calculation that will remove 10.75% of what you took in quarterly BEFORE calculating the 10.75% you owe. Confusing? You bet it is! Here's the formula:
If Y equals your total income, including the Denver tax you collected,
and X equals your total income, NOT including the Denver tax you collected
Y divided by 1.1075 = X (your total short term rental income)
X times 0.1075 = the total amount you should pay in taxes
So say you collected $1000 in a quarter. First calculate the amount you should actually be paying taxes on:
1000 divided by 1.1075 = $902.93. That is the total amount you should be paying the Lodger's tax on!! Next step:
902.93 times 0.1075 = $97.06. The tax form will calculate this for you, but it's nice to be able to double check.
Looks like I might be wrong about the cleaning fee deduction, which seems strange to me. I'd love to see if hotels collect a lodger's tax on their service fees, or just on the base price of the room. Hmm. Might go and ask how they do it.
