How this calculator works.
When you buy, the county reassesses the home at the purchase price. The 1% base rate and any voter-approved local rates are charged on that assessed value. After that, the assessed value can rise by no more than 2% a year while you own it.
The homeowners' exemption takes $7,000 off the assessed value of your primary residence once you file for it, which saves roughly $70 to $90 a year. Mello-Roos and other special assessments are flat charges set by the district, so they are added in dollars.
The effective rate is the total yearly tax divided by the price. The table projects the next ten years, with the ad valorem portion rising 2% a year; actual increases can be lower, and Mello-Roos schedules vary.
Tax = (price − exemption) × (1% + local rate) + special assessments. Effective rate = tax ÷ price.
