SIOUXLAND---The state's top tax official has used her authority to grant a tax extension to businesses and individuals living and working in the Missouri River flood zone.

Victoria Daniels, a public information officer in the Iowa Department of Revenue, says it's unclear how many taxpayers may be late in filing.

Taxpayers must submit sales and use taxes, plus any withholding for income taxes, on a quarterly basis.

But taxpayers living in the six counties that border the Missouri River now have until October 31st to file.

Taxpayers in Fremont, Harrison, Mills, Monona, Pottawattamie and Woodbury Counties who've been hit by flooding can qualify for extension and file their quarterly tax payments by October 31st without penalty or interest.

Daniels says her agency also has gotten a number of inquiries from the Dakota Dunes area, where people have temporarily relocated to Iowa because of the flooding there.

Daniels says most South Dakotans fleeing flooded homes will be considered temporary, not permanent residents of Iowa because they intend to move back to their South Dakota home.

The State of South Dakota, by the way, does not have a personal income tax.
