How to Avoid Tax Payment Penalties

Avoid Penalties by Understanding Postmarks

Property tax payments must be received, United States Postal Service (USPS) postmarked by the due date to avoid loss of the 5% discount or the addition of penalties/interest in accordance with State law. If the 1st installment is delinquent, a 3 percent penalty is imposed. If the 2nd installment is delinquent, a 6 percent penalty is imposed.

Postmarks are imprints the USPS applies to letters, flats and parcels to reflect the date, name, state and zip code of the USPS office that accepted custody of the mail. The postmark is generally applied, either by machine or by hand, with cancellation bars and is primarily used to prevent postage from being re-used.

Taxpayers who send their payments by mail are cautioned that the USPS only postmarks certain mail depending on the type of postage used. Additionally, the USPS may not postmark mail on the same day it is deposited by a taxpayer.

Mail that is postmarked

Mail that is not postmarked

  • Metered MailMail on which postage is printed directly on an envelope or label by a postage machine licensed by the USPS. Many private companies use these types of postage machines.
  • Pre-Cancelled Stamp: Stamps sold through a private vendor, such as stamps.com®.
  • Automated Postal Center (APC) Stamps: Stamps, with or without a date, purchased from machines located within a USPS lobby.
  • Permit Imprint: Pre-sorted mail used by bill pay services, such as online home banking.

If you use these types of postage, the USPS will not postmark your mail. You will lose your discount or we will impose a penalty and/or interest if we do not receive your mailed payment by the due date.

Safer Options

Purchase a POSTAGE VALIDATED IMPRINT (PVI) Label from a USPS retail counter or window. The PVI is applied to a piece of mail by personnel at the retail counter or window when postage has been paid to mail that item. The item is retained in USPS custody and is not handed back to the customer. The date printed on the PVI label is the date of mailing.
