Although voters didn’t approve Measure O, the ballot initiative that would have hiked county bed taxes from 10 percent to 12.5 percent, the Board of Supervisors indicated this week that they will still push to increase the 24-year-old rate in the future. In the 2013-2014 fiscal year, the bed taxes generated by hotels in cities — most of which charge a 12 percent tax — and the unincorporated regions raised a combined $46.3 million in revenue. In the last two fiscal years, according to a county report, all jurisdictions saw higher bed-tax revenue than in previous years, and county officials expect to see that revenue grow 5 percent over the next five years.
