Most school districts and some special districts provide an exemption from parcel taxes for qualified senior citizens. The individual districts administer and grant these exemptions.  If you are over the age of 65 and use the property as your principal residence, you may be eligible for a parcel tax exemption.  Please contact the districts directly at the phone numbers located under your name and address on the front of your property tax bill for exemption eligibility requirements, or visit the Marin County Property Tax Exemptions website.
