Nearly 500,000 property tax bills have yet to be mailed out in Orange county because of a glitch that asked some tax 

payers to pay twice.

About  350,000 of the incorrect tax bills had already mailed out when the error was found, the county is expected to resume mailing out the new forms next week.

The bogus forms told local property owners that they still owed property taxs – even though they are already paid through their monthly mortgage payments.

Some property owners who pay their taxes into “impound accounts” as part of their monthly mortgage payment received standard tax bills. Normally, taxpayers with impound accounts get a similar-looking letter, but it doesn’t have return envelopes enclosed and also has the words “INFORMATION COPY” on it.

The Treasurer’s Office blamed the mistake on “a computer programming error.”
