How do I pay my San Luis Obispo County property tax bill?

Pay online through the Taxes on the Web system at services.slocountytax.org, by mail with the envelope supplied, or in person at Room D-290 of the County Government Center, 1055 Monterey Street, San Luis Obispo.

Credit and debit cards carry a 2.35 percent processing fee with a $1.49 minimum, while eCheck has no added fee, so eCheck is the cheaper online route. The county’s page describes only the two installments and does not describe a monthly payment plan.

What happens if I don’t pay property taxes in San Luis Obispo County?

A late first installment gets a 10 percent penalty added to the unpaid balance. A late second installment gets 10 percent plus a cost whose amount the county’s page does not state.

If any installment is still unpaid at 5:00 p.m. on June 30, the property becomes tax defaulted and, in the county’s words, additional penalties and fees accrue.

The page does not list those amounts or any redemption interest and refers owners to its delinquent taxes page, so ask the Tax Collector for a current payoff on your parcel before you decide how to proceed.

How to sell a house in San Luis Obispo County when you owe property taxes

You can sell a house in San Luis Obispo County with unpaid property taxes. Taxes are a lien on the home, so escrow pays what is owed from your proceeds at closing and the buyer receives the property with the taxes current.

1. Get your payoff figure. Contact the Tax Collector at the County Government Center, or use the county phone directory at 805-781-5000, and ask for the amount due in the month you expect to close.
2. Expect proration. Escrow splits the current year’s tax between you and the buyer by the closing date.
3. Budget for transfer tax. The county-level rate is $0.55 per $500 of the sale price, so a $800,000 sale is $880 before any city tax. Ask escrow what applies to your address.
4. Watch the calendar. Closing before December 10 or April 10 avoids the 10 percent penalty on that installment, and closing before June 30 avoids tax-defaulted status.

A cash sale helps when time is the problem. There is no loan approval to wait for, so closing can be scheduled ahead of a tax deadline. See how we buy houses in San Luis Obispo County, our local page for San Luis Obispo, and the California real estate transfer tax report.
