Mississippi State Business Income Tax

What kind of tax will you owe on Mississippi business income?

Most states tax at least some types of business income derived from the state. As a rule, the details of how income from a specific business is taxed depend in part on the business’s legal form. In most states corporations are subject to a corporate income tax, while income from pass-through entities such as S corporations, limited liability companies (LLCs), partnerships, and sole proprietorships is subject to a state’s tax on personal income. Tax rates for both corporate income and personal income vary widely among states. Corporate rates, which most often are flat regardless of the amount of income, generally range from roughly 4% to 10%. Personal rates, which generally vary depending on the amount of income, can range from 0% (for small amounts of taxable income) to around 9% or more in some states.

Currently, six states – Nevada, Ohio, South Dakota, Texas, Washington, and Wyoming – do not have a corporate income tax. However, four of those states – Nevada, Ohio, Texas, and Washington – do have some form of gross receipts tax on corporations. Moreover, five of those states – Nevada, South Dakota, Texas, Washington, and Wyoming – as well as Alaska and Florida currently have no personal income tax. Individuals in New Hampshire and Tennessee are only taxed on interest and dividend income.

Apart from taxing business income through a corporate income tax or a personal income tax, many states impose a separate tax on at least some businesses, sometimes called a franchise tax or privilege tax. This is frequently justified as a tax simply for the privilege of doing business in the state. As with state taxes on business income, the specifics of a state’s franchise tax often depend in part on the legal form of the business. Franchise taxes are generally either a flat fee or an amount based on a business’s net worth.

Mississippi has both a corporate income tax and a corporate franchise tax. Your business may be subject to one, both, or neither of these taxes depending on its legal form. Additionally, if income from your business passes through to you personally, that income will be subject to taxation on your personal state tax return.

The corporate income tax applies to traditional (C-type) corporations. It is based on a series of marginal rates. The minimum income threshold for the lowest rate currently is set to change each year at least for the next five years. The specific breakdown for 2018 is as follows:

  • 3% on first $1,000 – $5,000 of taxable income (minimum amount increases by $1,000 each subsequent year until 2022 at which point there is no tax on first $5,000 of income)
  • 4% on next $5,000 of taxable income; and
  • 5% on income in excess of $10,000.

For purposes of comparison, note that Mississippi taxes personal income at exactly the same rates as corporate income. Returns are due on the fifteenth day of the fourth month after the close of the corporation’s tax year. For corporations whose tax year follows the calendar year, that means a due date of April 15th.

The corporate franchise tax—which applies to both traditional corporations and S corporations—is based on an element of a business’s net worth. More specifically, the tax is computed at $2.50 per $1,000 of the greater of:

  • capital used, invested, or employed in the state; or
  • the total assessed value of property in the state.

There is a minimum franchise tax of $25. Returns are due on the fifteenth day of the third month after the close of the corporation’s annual accounting period. For corporations whose accounting period follows the calendar year, that means a due date of March 15th.

Here’s a brief look at additional details for five of the most common forms of Mississippi business: corporations (C corporations), S corporations, LLCs, partnerships, and sole proprietorships.

Corporations

Mississippi corporations are subject to Mississippi’s corporate income tax at marginal rates ranging from 3% to 5% of taxable income. In addition, Mississippi corporations must pay the corporate franchise tax.

Example: For the 2018 tax year, your Mississippi corporation had taxable income of $400,000. Also, the value of the corporation’s capital was greater than that of its property in the state; the value of the capital was $200,000. Your corporation will owe Mississippi corporate income tax in the amount of $19,820 (3% of amount from $1,000 – $5,000 plus 4% of next $5,000 plus 5% of remaining $390,000). The corporation will also owe Mississippi corporate franchise tax in the amount of $500 ($200,000 of capital taxed at $2.50 per $1,000).

S Corporations

An S corporation is created by first forming a traditional corporation, and then filing a special form with the IRS to elect S status. Unlike a traditional corporation, an S corporation is not subject to separate federal income tax. Rather, taxable income from an S corporation is passed through to the individual shareholders, and each individual shareholder is subject to federal tax on his or her share of the corporation’s income. In other words, S corporations are pass-through entities. (Note that a shareholder’s share of the S corporation’s income need not actually be distributed to the shareholder in order for the shareholder to owe tax on that amount.) Mississippi does not require S corporations to pay income tax. However, they are required to pay the state’s corporate franchise tax. In addition, each individual S corporation shareholder will owe state tax on his or her share of the company’s income.

Example: For the 2018 tax year, your Mississippi S corporation had taxable income of $400,000. Also, the value of the corporation’s capital was greater than that of its property in the state; the value of the capital was $200,000. The corporation will owe Mississippi corporate franchise tax in the amount of $500 ($200,000 of capital taxed at $2.50 per $1,000). The franchise tax aside, the corporation’s net income will be allocated to you and your fellow shareholders, and you will each pay tax on your own portions on your individual state tax returns. Rates will vary depending on overall taxable income.

Limited Liability Companies (LLCs)

Standard LLCs are pass-through entities and are not required to pay income tax to either the federal government or the State of Mississippi. LLCs are also not required to pay Mississippi’s corporate franchise tax. Instead, income from the business is distributed to individual LLC members, who then pay federal and state taxes on the amounts allocated to them.

While by default LLCs are classified for tax purposes as partnerships (or, for single-member LLCs, disregarded entities), it is possible to elect to have your LLC classified as a corporation. In that case, the LLC would also be subject both to Mississippi’s corporate income tax and corporate franchise tax.

Example: For the latest tax year, your multi-member LLC, which has the default tax classification of partnership, had taxable income of $400,000. The $400,000 in net income will be divvied up between you and your fellow LLC members, and you will each pay tax on your respective portions on your respective, individual Mississippi tax returns, with rates varying depending on overall taxable income.

Partnerships

Mississippi partnerships are subject neither to Mississippi’s corporate income tax nor to the state’s corporate franchise tax. Instead, income from the business is distributed to the individual partners, who then pay tax on the amount distributed to them on both their federal and state tax returns.

Example: For the latest tax year, your partnership had net income of $400,000. This amount will be divvied up between you and your fellow partners, and you will each pay tax on your respective portions on your respective, individual Mississippi tax returns, with rates varying depending on overall taxable income.

Sole Proprietorships

Mississippi sole proprietorships are subject neither to Mississippi’s corporate income tax nor to the state’s corporate franchise tax. Instead, income from your business will be distributed to you as the sole proprietor, and you will pay tax on that income on your individual federal and state tax returns.

Example: For the latest tax year, your sole proprietorship had net income of $100,000. The $100,000 in net income is distributed to you personally, and you pay tax on that income on your individual federal and state tax returns.

Note on Multistate Businesses and Nexus

Our primary focus here is on businesses operating solely in Mississippi. However, if you’re doing business in several states, you should be aware that your business may be considered to have nexus with those states, and therefore may be obligated to pay taxes in those states. Also, if your business was formed or is located in another state, but generates income in Mississippi, it may be subject to Mississippi taxes. The rules for taxation of multistate businesses, including what constitutes nexus with a state for the purpose of various taxes, are complicated. If you run such a business, you should consult with a tax professional.
