When are property taxes due in San Luis Obispo County?
For the 2026/27 Fiscal Year bill, San Luis Obispo County splits the bill into 2 payments, the first due November 1, 2026 and the last February 1, 2027. A first installment not paid by December 10, 2026 gets a 10% penalty. A second installment not paid by April 12, 2027 gets a 10% penalty plus a $20 collection cost. Taxes still unpaid at 5 p.m. on June 30 become tax-defaulted, which adds a $15 redemption fee and a penalty of 1.5% a month on the unpaid tax. An owner can then start an annual payment plan by paying at least 20% of the amount owed plus a $73 setup fee, or a monthly plan with a $96 setup fee and payments of at least $100 a month plus a monthly processing fee. After five years in default the county gains the power to sell the property, unless an annual plan is kept current.
