October 19, 2017: Property Tax Information
This fiscal year, for the first time, those using the new Los Osos wastewater system will see the costs included on their annual property tax bills, which were recently mailed. One charge on the tax bills will repay the bonds issued for the construction costs. A second charge covers the costs of operating the sewer. This year is the first year that the full costs of the sewer have been billed on the tax bills, which is a much more efficient method of billing than having Public Works bill and collect separately, as was done last year. Residents should be aware that these costs are not tax-deductible even though they appear on the tax bills. Full explanations of the sewer project and related costs are available on the Property Tax Billing Information Page. In addition to the explanations on the web site, both Public Works and the Tax Collector’s office have staff trained and available to answer questions by calling (805) 788-6088 or submitting an eForm.
