  • About This Answer

    To calculate the exact amount of property tax you will owe requires your property's assessed value and the property tax rates based on your property's address. Please note that we can only estimate your property tax based on median property taxes in your area. There are typically multiple rates in a given area, because your state, county, local schools and emergency responders each receive funding partly through these taxes. In our calculator, we take your home value and multiply that by your county's effective property tax rate. This is equal to the median property tax paid as a percentage of the median home value in your county.

There are several ways to pay your property taxes in Alameda County. You can go online to the website of the county government and look up your property taxes. Once online, you can pay on the site – but be aware that a convenience fee of 2.5% will be charged if you pay by credit card and a flat fee of $3 will be charged if you pay from your checking or savings account via electronic check.

You can also call the county at 510-272-6800 to settle your property tax bill. You’ll be able to use the interactive voice response (IVR) system to find out the size of your property tax bill and to pay by credit card. The same 2.5% fee for credit card payments applies if you pay by phone.

Alameda County has its own app for property tax payments. Called “AC Property” it’s available for iPhone and Android. The 2.5% credit card fee applies on the app, too.

If you want to go old-school, you can pay by mail or in person. Your property tax bill will come with a return envelope you can use to send a check (don’t send cash). You can detach the payment coupon from your bill and keep the rest of the bill for your own files. You won’t get a receipt for paying by mail, so check with your bank to make sure that the check clears.

To pay in person, you can head to the Oakland office of Alameda County during a weekday. There, you can pay by cash, check, money order, cashier’s check or certified check. Or you can use a kiosk to pay by credit card or electronic check (a fee will apply).

If your check is returned or your credit card payment is denied, you’ll incur a fee of $61, plus late payment penalties and costs if you’re past the due date. You’ll be notified in the event that this occurs.

Alameda County Property Tax Breaks

Military personnel can apply for Alameda County’s Property Tax Relief for Military Personnel. If your application is successful, you’ll be allowed to defer payment of your property taxes in accordance with the Soldiers’ and Sailors’ Civil Relief Act. Your deferred payments won’t rack up late fees, but will be subject to interest at 6% annually.

If you’re behind on your property taxes (this is known as having secured property tax delinquencies), you can apply to set up an Installment Plan Agreement with Alameda County. This will allow you to redeem the property on which back taxes are owed. It applies to property taxes that have been delinquent for a year or more, and will allow you to make up to five catch-up payments. If you have an installment plan in place, your property can’t be sold out from under you and you will retain the right to redeem the property.

Another property tax break available to Alameda County residents (and all other California residents) is the Property Tax Postponement Program. To qualify, applicants must be seniors, be blind or have a disability. Applicants must also have at least 40% equity in their home and an annual household income of $35,500 or less.

How Your Alameda County Property Tax Bill Works

What’s the schedule for Alameda County property taxes? The first installment is due on November 1, and is considered delinquent if not paid by 5:00 p.m. on December 10. Delinquent payments are subject to a 10% penalty.

The second installment is due on February 1 of the following year and is considered delinquent if not paid by 5:00 p.m. on April 10. As with the November deadline, late payments will incur a 10% penalty.

If December 10 or April 10 happens to fall on a Saturday, Sunday or a legal holiday, your payment won’t incur a 10% penalty as long as it’s made by 5 p.m. on the following business day.

If you have the money on hand and you want to knock out both property tax installments at once, you can pay the “Total Amount Due” (as listed on your tax statement) by the December 10 deadline. Be sure to include both installment pay stubs if you’re paying by mail.

Often, homebuyers include property tax payments with their mortgage payments and the mortgage company remits the property taxes to the county. If you have this arrangement in place and then the lender stops paying your property taxes (because you pay off your mortgage, for example), you can simply view and pay your bill online, or contact the county to receive a duplicate tax bill complete with payment stub if you plan to pay by mail.

Rank County Property Tax Rate School Rating Crimes Per 100k People

Methodology

Our study aims to find the places in the United States where people are getting the most for their property tax dollars. To do this we looked at school rankings, crime rates and property taxes for every county.

As a way to measure the quality of schools, we calculated the average math and reading/language arts proficiencies for all the school districts in the country. Within each state, these schools were then ranked between 1 and 10 (with 10 being the best) based on those average scores.

For each county, we calculated the violent and property crimes per 100,000 residents.

Using the school and crime numbers, we calculated a community score. This is the ratio of the school rank to the combined crime rate per 100,000 residents.

We used the number of households, median home value and average property tax rate to calculate a per capita property tax collected for each county.

Finally, we calculated a tax value by creating a ratio of the community score to the per capita property tax paid. This shows us the counties in the country where people are getting the most bang for their buck, or where their property tax dollars are going the furthest.
