Corporate Income Tax

In Mississippi, corporate income is subject to a state income tax. This tax is levied in Section 27-7-5 of the Mississippi Code. Unless a company is taxable in another state, this tax is based on the company's net taxable income.

Income tax for multi-state corporations is calculated by determining a Mississippi to total company ratio that is applied to the net business income for the corporation. For retailers, wholesalers, service providers, and many other business operations, income is apportioned based on a ratio of sales in Mississippi versus sales for the total entity. For manufacturers, income tax is apportioned using a three factored approach that consists of property, payroll, and sales in Mississippi related to everywhere.

After the apportioned net taxable income is calculated, additional non-business income attributable to Mississippi is added to the calculated amount to arrive at the Mississippi net taxable income.

Corporate Franchise Tax

Most corporations engaged in business in Mississippi are subject to franchise tax, as levied in Sections 27-13-5 and 27-13-7 of the Mississippi Code. Franchise tax is a tax that is assessed on the company's capital value. The capital value for the corporation is calculated based on:

  • Capital stock issued and outstanding
  • Aid-in Capital, Surplus, and Retained Earnings, including deferred taxes, deferred gains, deferred income, contingent liabilities, and other true reserves.

For multi-state corporations, capital is pro-rated based on the following formula:

Book value of MS real and tangible personal property + MS Gross Receipts

Book value of total real and tangible personal property + total Gross Receipts

This ratio is then applied to the corporation's total capital value to calculate the amount of capital to be apportioned to Mississippi. The apportioned capital is then multiplied by the franchise tax rate to determine the Mississippi franchise tax liability. This franchise tax rate is $2.50 per $1,000 of Mississippi capital.

Sales and Use Tax

The sales and use tax exemption for construction and expansion is allowed on eligible machinery and equipment purchases related to a new or expanded facility. These purchases are subject to a one-half or full exemption, depending upon construction location. This exemption is available from the beginning of construction or expansion up until three months after initial start-up. The exemption amount allowed is listed below:

County ClassificationExemption Amount
Tier III (less developed)100%

Tier I (more developed)50%

Contractor's tax – a one-half or full exemption of sales and use tax is available on component building materials used in construction, provided that the materials are sold to, billed to, and paid for by the eligible company. The labor portion of the contract cannot be exempted and is subject to the 3.5% contractor's tax. This exemption applies to retail rate taxes, but does not cover tagged vehicles, ongoing expenses, or supply items.

Property Tax

Counties and municipalities levy a property tax on real and tangible personal property in Mississippi. Generally, property is assessed at 15% of true value.

State Unemployment Compensation Tax

Mississippi levies an unemployment compensation tax on the first $7,000 of an employee's annual wages, as provided for in Section 71-5-1 of the Mississippi Code. The maximum contribution rate for employers is 5.4%, with the minimum rate equaling 0.9%. Both the state minimum rate and the business's rate vary from year to year. New employers in the state are assigned an initial rate of 2.7% of wages until the Mississippi Department of Employment Security can compute an actual experience rate for the employer. Rates are recalculated each October and apply to the following year's wages. Rates are adjusted after two to three years of Mississippi filings, depending upon what time of year the employer begins reporting.
