Look Up & Pay Your California Property Tax, County by County

Property tax is collected by the county, not the state, so you look it up on your county Treasurer-Tax Collector's portal (linked for each county below). Most portals search by Assessor's Parcel Number (APN); many also take a street address. The APN is printed on any prior bill, on your deed, and in the county Assessor's parcel viewer.

Yes, in every county. All 58 county tax collectors run an online lookup and payment portal (linked below). E-check (ACH) is free or near-free in most counties; credit and debit cards carry a processor fee, typically about 2.2%–2.5% of the payment. Where the county publishes its fees they are listed next to its link.

Your Assessor's Parcel Number (APN) or the property address, and a bank account (routing and account number) for an e-check or a card. You do not need an account on most portals. Pay each installment separately or both at once; the portal shows what is currently due, including any penalties.

Statewide: the first installment is due November 1 and delinquent after December 10; the second is due February 1 and delinquent after April 10 (next business day if the 10th falls on a weekend or holiday). A 10% penalty is added after each delinquency date, plus a $10 cost on the second installment. The same dates apply in every county.

Look the bill up on the county portal and pay it there — not receiving a bill does not excuse a late payment or the penalty (Revenue and Taxation Code §2610.5). Each county also lists a phone number for a duplicate bill; where the county publishes it, it is shown below.

On the tax bill itself, or on the county Assessor's site (linked below for each county). Your Tax Rate Area number determines which voter-approved bonds are added to the 1% base; the 'What's in your property tax' page for your county breaks that down.
