Sequim will begin collecting an expanded utility tax on Feb. 10.
The city already levies a 3 percent tax on electricity and telephone service.
The City Council, as part of its 2006 budget deliberations Monday night, extended the tax to apply to water, garbage, gas and sewer services.
The estimated annual additional revenue to city coffers was estimated at between $320,000 and $350,000 in a staff report to City Council members last month.
The 6 percent figure is the maximum allowed by state law without a vote of the citizens to tax beyond that rate.
