Mississippi corporation deadlines: Annual report and Franchise tax

Annual report

Due
Due April 15 each year; the window opens January 1. Filing is online only. Nonprofit corporations file a separate report by May 15 at no charge.
First one
First due April 15 of the year after incorporation.
Fee
$25 for a domestic corporation.
Frequency
Annual

If it is late

No late fee. A report 60 days past due becomes a ground for administrative dissolution; the state then serves notice and waits a further 60 days before dissolving.

Franchise tax

Due
Filed with the corporate income tax return, due the 15th day of the 4th month after the accounting year closes - April 15 for calendar-year corporations. The tax is being phased out and ends after tax year 2027. Nonprofits are exempt.
First one
Owed for each tax year the corporation is registered in Mississippi, beginning with its first accounting year, even if inactive.
Fee
At least $25 every year through tax year 2027, whatever the capital or income. Above $100,000 of Mississippi capital, a per-$1,000 rate applies that steps down each year until the tax ends.
Frequency
Annual

If it is late

Ordinary revenue-department late-filing and late-payment penalties accrue, up to 25% in aggregate, plus interest. Nonpayment does not dissolve the corporation - a separate agency administers the tax.
