Tuolumne County Property Tax Guide for Homeowners and Sellers

Last updated November 13, 2026. Reviewed by the Cash Home Buyers CA team. Dates below come from the Tuolumne County Tax Collector’s 2025-26 schedule; sources are listed at the end.

Tuolumne County property taxes are paid in two installments, due November 1 and February 1, and a late installment carries a 10 percent penalty. The county’s 2025-26 schedule made the first installment delinquent on December 11, 2025 and the second on April 11, 2026, because the usual December 10 and April 10 dates fell on a weekend or were counted by postmark.

The Tax Collector states it cannot extend the time of payment. If you sell the house, anything still owed is paid from your proceeds at closing. For how selling works across the county, see our Tuolumne County cash home buyers page.

What happens if I don’t pay Tuolumne County property taxes?

A late installment brings the 10 percent penalty. Taxes still unpaid at the end of the fiscal year become tax-defaulted; the county’s page showed defaulted status as of July 1, 2025.

We did not find the default interest rate or tax-sale timing on the county’s page, so ask the office for an exact payoff before you decide. If you are also behind on the mortgage, read about selling a house in foreclosure.

How to sell a house in Tuolumne County when you owe property taxes

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

1. Get a payoff figure. Ask the Tax Collector for the amount due in the month you expect to close.
2. Give it to escrow. Escrow lists the taxes with your mortgage and other liens and pays them at closing.
3. Budget for transfer tax. California’s statutory county rate is $0.55 for each $500 of value; use the calculator below. The contract decides who pays.
4. Watch the calendar. Closing before the delinquent date avoids the penalty on that installment.

A cash sale helps when time is the problem, because there is no loan approval to wait for. Call (424) 435-2326. If you inherited the house, read how to sell an inherited house.
