What is the Minnesota corporate income tax?

MN corporate income tax

Minnesota's corporate income tax is a business tax levied on the gross taxable income of most businesses and corporations registered or doing business in Minnesota. The Minnesota corporate income tax is the business equivalent of the Minnesota personal income tax, and is based on a bracketed tax system. Similar to the personal income tax, businesses must file a yearly tax return and are allowed deductions such as wages paid, cost of goods sold, and other qualifying business expenses.

What kind of businesses have to pay the Minnesota corporate income tax?

In general, all businesses operating in Minnesota which are not registered as a flow-through entity (like a sole proprietorship, a partnership, or an S-Corporation) must report their income and pay both Minnesota and Federal corporate income taxes on their earnings. The most commonly used business structure that is subject to corporate taxes is a C-Corporation.

Because C-Corporations pay corporate taxes on their revenue in addition to the personal income taxes shareholders and owners pay on profits withdrawn from the company, profits received from a C-Corporation are subject to a phenomenon known as double taxation.

S-Corporations and other flow-through entities aren't subject to the double taxation of revenue imposed on a C-Corp, because they aren't required to pay corporate taxes on their revenue. However, the owners or members of the corporation must report their share of the corporation's income on their personal tax returns and pay Minnesota and federal income tax.

All incorporated Minnesota businesses, regardless of whether or not they are required to pay any taxes, should file at least an informational tax return with the Minnesota Department of Revenue as well as a federal business tax return (Form 1120) with the IRS.

Minnesota Nonprofit Tax Exemptions

Certain nonprofit entities registered in Minnesota may be able to exempt some or all of their qualifying income from Minnesota and federal income taxes. Specifically, certified Minnesota 501(c) nonprofit corporations are exempt from the Minnesota corporate income tax. Some of the most common 501(c) organizations include:

Educational & Scientific Institutions
Nonprofit educational and scientific groups are tax-exempt, including nonprofit schools and colleges and certain research institutions. Covered under § 501(c)(3) of the IRC.
Tax-Exempt Charities
Bona-fide charities are exempt from all corporate income taxes, including both religious and non-religious charities. Covered under § 501(c)(3) of the IRC.
Tax-Exempt Religious Institutions
Bona-fide religious institutions including churches, synagogues, and mosques are exempt from corporate income taxes under § 501(c)(3) of the IRC
Tax-Exempt Recreational Organizations
Social clubs and recreational groups may collect dues and other funds as a tax-free organization as long as the primary purpose of the group is not for profit. Covered under § 501(c)(7) of the IRC.
Labor Unions
Labor unions and worker's organizations are exempt from taxation on dues and other forms of income. Covered under § 501(c)(4) and § 501(c)(5) of the IRC.

In order to gain Minnesota tax-exempt status, a corporation must qualify as a 501(c) and obtain a Nonprofit Tax-Exempt ID Number from the IRS. Minnesota may also require nonprofits to file additional paperwork with the Minnesota Department of Revenue to gain exemption from Minnesota's corporate taxes.

In addition to the Minnesota corporate income tax, Minnesota corporations must also pay the federal corporate income tax. Like the personal income tax the federal business tax is bracketed based on income level, with eight corporate tax brackets.

The federal corporate tax's brackets differ from the personal income tax in that the brackets are not completely progressive (the last tax bracket is not the highest). This allows the corporate tax burden to be spread more evenly among companies with various revenue levels. The current corporate tax rates have been in effect since 1994 (unlike the federal income tax brackets, which are updated yearly for inflation).

All Minnesota state taxes are deductible from gross income when calculating federal taxes, so any Minnesota corporate income tax paid can be deducted from a business' gross taxable income before calculating your federal taxable income.
