Property taxes in Biloxi are billed and collected by Harrison County.

Biloxi’s tax rate for 2026

It sets 76.35 mills for the city and the Biloxi Public School District. Mayor Andrew “FoFo” Gilich had asked for a three-mill increase; the city levy in the resolution, 31.10 mills, is one mill more than the 30.10 mills the city levied the year before.

How your bill is figured
Mississippi assesses property at a share of its true value. The Department of Revenue sets the classes:
- Single-family home you own and live in: 10% of true value
- Other real property, such as rentals, land and commercial buildings: 15%
- Business personal property: 15%
- Motor vehicles: 30%
One mill is $1 for every $1,000 of assessed value. The state’s own example: a $100,000 home assessed at 10% has an assessed value of $10,000; at 125 mills, the tax is $1,250 before any homestead exemption. The Tax Assessor must revalue real property at least once every four years.
Homestead exemption
The homestead exemption lowers the tax on your main home. Apply at the Harrison County Tax Assessor’s office between Jan. 1 and April 1. You must own and live in the home on Jan. 1, and the deed must be filed with the Chancery Clerk before Jan. 7.
- Regular exemption: a credit of up to $300 against the tax on the home.
- Age 65 or older, or totally disabled: no tax on the first $7,500 of assessed value.
- Total exemption: veterans with a service-connected total disability, honorably discharged veterans age 90 or older, and certain surviving spouses.
Bring Social Security numbers and dates of birth for every applicant, the purchase price, the down payment, the closing statement and the tag numbers of every vehicle you own. Once approved, the exemption renews each year unless something changes, such as a marriage, divorce, death, deed change or turning 65. You must keep Mississippi car tags and file Mississippi income tax to keep it.
How to appeal
If you think your property value is wrong, talk to the Tax Assessor’s office first. To appeal formally, ask for a hearing before the Harrison County Board of Supervisors. The Department of Revenue says an appeal normally must be filed by the first Monday in August before the taxes are due; the Chancery Clerk’s office handles the paperwork.
