4/21/17 Dayton government officials blamed a postal error as the reason some city tax returns mailed to a PO box in Akron bounced back to senders as undeliverable.|

But at least 15 tax filers have said they had their letters returned as undeliverable, according to city estimates.

The number could be higher – nearly 2,000 filers received refunds last year – but city officials believe the problem was limited to items postmarked on just one day.

The city said Friday the issue appears to be on the post office’s end and indicated the Akron office was looking into the matter.

The city instructed taxpayers whose returns could not be delivered to send the documents and the original mailing envelope directly to the city to avoid being counted as late.

David Van Allen, an Ohio spokesman for the U.S. Postal Service, said the PO box is active and accepting deliveries and a piece of mail that was returned and he reviewed appeared to result from an “anomalous” service error.

“We apologize for the inconvenience” he said. WHIO
