If you receive notice of a NSF check, you must pay the amount of the check, a $25.00 return check fee, and possibly a 10% penalty. It is in your best interest to contact the nearest Lake County Treasurer's office upon notification of an NSF check. NSF payment must be paid by either by Cashier's Check, Money Order, or Cash. NO PERSONAL CHECKS WILL BE ACCEPTED. A separate payment is required for the returned check fee of $25.00 charged by Lake County, the $25.00 is a service fee and it is not applied to any taxes owed. If this is a bank error, you must have a letter from the bank stating it is their error in order to have the fee waived. For further information, contact the Book-Keeping Department at (219) 755-3760.
