Plan to mail your property taxes this year? Do it early due to USPS changes affecting postmarks

Date

The U.S. Postal Service (USPS) is implementing the "Delivering for America" plan, which involves consolidating mail processing into new Regional Processing and Distribution Centers. This change will alter the postmark date on what you mail, which will no longer accurately reflect the actual date when your item was sent. Under the new system, mail is collected from local post offices once a day, typically in the morning (note that mailboxes may not reflect these updated pickup times), and transported to a regional center for processing. This means that a letter mailed on a Monday will not be postmarked until Tuesday or Wednesday. This can have severe consequences for time-sensitive documents, such as making tax payments. While much mail is processed and postmarked at large regional centers, mail can also be hand-canceled at smaller post office branches only upon your request. 

Clackamas County Assessor Bronson Rueda recommends that if you need a piece of mail postmarked with a specific date, like your property tax payment, you should take it to the counter of a local post office and request a hand cancellation. The postal worker will stamp the date on your mail and cancel the stamp by hand. If you are unable to receive a hand cancellation, please mail your property tax payments as early as possible. You can also choose to pay online or in person.
