Jefferson Parish began mailing out 175,369 property tax bills Wednesday, outlining to residents and business owners how they can go about paying up by the end of the year.

Payments not postmarked by Dec. 31 will begin incurring interest on that date.

Sheriff Newell Normand, the parish tax collector, said any property owner who hasn’t received a bill by Dec. 15 should contact his office.

The tax notice format is unchanged from last year. Taxpayers are asked to enclose the payment stub with their payment in the self-addressed envelope provided with the bill.

Tax bills also can be paid in person at the Government Building at 200 Derbigny St. in Gretna or online — with a 2.49 percent fee for credit cards — at www.jpso.com under the Pay Taxes & Licenses tab.

Checks also can be dropped into a drop box on the first floor of the Sheriff’s Office building at 3300 Metairie Road.

Questions about payment dates, amounts, refunds, copies of a notice, redemptions or other issues regarding collection should be directed to the Sheriff’s Office’s Property Tax Division at (504) 363-5710.

Questions concerning the amount of an assessment, a change in mailing address or a homestead exemption should go to the Assessor’s Office at (504) 362-4100.

Kenner sent out its property tax bills earlier this week. They can be paid by returning the self-addressed envelope, in person at 1801 Williams Blvd, Suite 106, or on the city’s website, www.kenner.la.us.
