Per the Star Advertiser this morning, Hawaii tax revenues soared to a record high in April. What would be nice is if they explained how "they are counting sales tax and retail sales". I do not understand how they differentiate a retail sale or the tax generated by such as being tourism related. An individual spends $200 at Ala Moana, how do they know if he is a resident or a tourist. Maybe track credit cards, but that would not take into account cash sales. Might be interesting to find the yearly total of sales taxes and divide the figure by the number of residents in Hawaii and come up with a figure.
These figures most likely do not account for the amount of income generated by tips in the service industries. From experience, I know that a large portion of this is not reported as income, but goes into the economy as it is being spent by residents. Tourism related, but really no way account for it.
As for the factoring in of the percentage leaving the Islands due to the non local ownership of hotels, car rentals and airlines, it would be interesting to know that figure. I believe that it is still true that the daily revenues from Costco leaves the State on a daily basis. Is the revenue generated by Costco counted as partially generated by Tourism? On a daily basis, following the arrivals of tourists on Maui, a major first stop for them is Costco and they load up prior to heading to where they are staying. Is that counted as Tourism generated?
