Just fyi - How you get to 14.95% -- hotel rooms are a service that general sales tax does not apply to, and there is usually a separate law specifying the hotel rate tax. In Georgia they also add a fee.

So the general sales tax is irrelevant and there is a specific tax rate for hotel rooms listed here: https://cfo.dc.gov/page/tax-rates-and-revenues-sales-and-use-taxes-alcoholic-beverage-taxes-and-tobacco-taxes

Still, good writeup, no coincidences here.
