Avoid Late Payments
To avoid state statute penalties, only U.S. Postmarked (not metered) envelopes will be accepted. Must be postmarked prior to or on the due date.
- To pay by installment - send installment coupon and check prior to the due date.
- To pay in full - send both installment coupons and check, keeping bottom portion for your records.
- Because of electronic lock box processing, post-dated or unsigned checks will be processed on the day they are received, which may incur additional fees if returned by your bank.
Special Notes About Checks
When paying by check be sure that the face of your check has the following:
- Name and current address
- 10-digit Property Index Number (PIN#)
- Current date (no post-dated checks)
- Valid signature
- Made payable to Lake County Collector
