General Tax Information
1. When will I receive this year's tax bill?

The current year tax bill is mailed out mid-December.
Example: The 2024 tax bill will be mailed out mid-December, 2024.

2. Can I pay or find out what I owe on this year's taxes before the bills are mailed?

No, we do not have this information until December, and the County Treasurer's office is not able to accept payments until the data is uploaded to our computers. This typically happens at the same time the tax bills are mailed.

3. What is the tax timeline?

Tax bills are mailed.
January 31:                      
First half due. Also OKAY to pay in full.
July 31:                            
Second half due.
We mail a reminder to anyone that still owes on the current year taxes. An asterisk (*) on the reminder will indicate if there are also prior year taxes still due.

4. For payments, what is considered "on time"?

We go by postmark. If your envelope is postmarked by the deadline date, your payment will be considered on time.
If you are down to the deadline, you may want to take your envelope to the post office to verify that it receives the postmark in time.

5. Can I pay with a personal check?

Yes, personal checks are always accepted unless you are paying for a tax year that is already in the foreclosure process. See the "Foreclosure Timeline" for more information.

6. May I pay with a credit or debit card if I come to the Treasurer's Office?

Yes. We now accept credit or debit cards. There is a 2.2% fee charged by the credit card company.
We do still accept checks, cashier checks, money orders or cash.
You can also go online and pay with credit or debit card for the 2.2% fee or you can use an echeck for $0.25 fee.

Late (Delinquent) Taxes
1. If I am behind in my taxes, when will the foreclosure process begin?

We foreclose one year at a time, beginning after three years. (Timeline)
August 1, 2024 - Foreclosure process will begin on 2020 taxes.
March 2025 - Foreclosure deadline for 2020 tax payments.
August 1, 2025 - Foreclosure process will begin on 2021 taxes.
March 2026 - Foreclosure deadline for 2021 tax payments.

2. I know there is a $190 In-REM foreclosure process fee (Effective 07/25/23). How can I avoid that fee?

Your taxes for the in-foreclosure tax year must be paid before October 1st of the foreclosure year to avoid this fee. On October 1st, the $190 fee (Effective 07/25/23) will be added to your bill.

3. May I pay with a personal check?

Yes, personal checks are always accepted unless you are paying for a tax year that is already in the foreclosure process. Once we send out the certified foreclosure letter in December, personal checks will no longer be accepted for that tax year's payments or fees. You must pay with certified funds, money order, bank check, or cash. NOTE: We request the $190 fee (Effective 07/25/23) to be paid with a separate Cashier's Check or Money Order. 

4. When and how much interest is added to my taxes?

1% interest is added on the 1st day of each month.

5. I want to pay up my back taxes. Do you offer suggested payment plans?

Yes, we do. If you would like one, please let us know about how much you can afford per month. We can put one together for you, and send it to you via mail or email.

6. I owe back year taxes, but I want to pay the current year first, to avoid interest. May I do this?

Yes, but you will need to clearly specify that you want to pay the current year first to avoid interest. Our default procedure is to pay the oldest year first.

7. I purchased a home, and later found out the previous owner had unpaid taxes. Can these taxes be waived, since I didn't know about them?

No. The taxes became your responsibility when you purchased the home. If you wish to pursue the topic with your realtor or former owner, you may. But ultimately, the taxes are now your responsibility.
