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.
Montana is like most states in that it taxes corporate income, but unlike many states in that it does not have any franchise or privilege tax generally applicable to businesses. Thus, for the most part, unless your business is a traditional corporation (a C corporation), your business itself will not be subject to a state tax on income or net worth. However, if income from your business passes through to you personally, that income will be subject to taxation on your personal state tax return.
Montana’s corporate income tax (CIT) is computed at a flat rate of 6.75% with a minimum tax of $50. (Multistate corporations that do not own or rent real estate or have personal property in Montana, whose only activity in Montana is making sales, and that have $100,000 of less of sales in the state, may pay an alternative tax of 0.5% of their Montana gross receipts.) Montana CIT returns are due on the 15th of the fifth month after the close of the tax year – for companies whose tax year corresponds with the calendar year, this means returns are due on May 15th.
For purposes of comparison, note that in recent years Montana has taxed personal income at marginal rates ranging from 1.0% to 6.9%.
Let’s briefly look at additional details for five of the most common forms of Montana business: corporations (C corporations), S corporations, LLCs, partnerships, and sole proprietorships.
Montana corporations are subject to Montana’s corporation license tax at a flat rate of 6.75% of taxable income.
Example: For the 2018 tax year, your Montana corporation had taxable income of $100,000. Other things being equal, the corporation will owe Montana corporate income tax in the amount of $6,750 (6.75% of $100,000).
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 generally 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 usually 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.) Montana recognizes the federal S election, and Montana S corporations are not required to pay the state’s corporate income tax. However, an individual S corporation shareholder will owe tax on his or her share of the company’s income.
Example: For the 2018 tax year, your Montana S corporation had net income of $100,000. The $100,000 will be allocated to you and your fellow shareholders, and you will each pay tax on your own portions on your respective state tax returns. The rate will vary depending on your overall taxable income for the year.
Like S corporations, standard LLCs are pass-through entities and are not required to pay income tax to either the federal government or the State of Montana. Instead, income from the business is distributed to individual LLC members, who then pay federal and state taxes on the amount distributed to them.
By default, LLCs are classified for tax purposes as partnerships (or, for single-member LLCs, disregarded entities). However, it is possible to elect to have your LLC classified as a corporation. In that case, the LLC would also be subject to Montana’s corporate income tax.
Example: For the 2018 tax year, your multi-member LLC, which has the default tax classification of partnership, had net income of $100,000. The $100,000 in net income will be divvied up between you and your fellow LLC members, and you will each pay tax on your own portions on your respective state tax returns. The rate will vary depending on your overall taxable income for the year.
Income from partnerships 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 2018 tax year, your partnership had net income of $100,000. The $100,000 in net income will be divvied up between you and your fellow partners, and you will each pay tax on your respective portions on your respective state tax returns. The rate will vary depending on your overall taxable income for the year.
Income from your business will be distributed to you as the sole proprietor, and you will pay tax to the state on that income.
Example: For the 2012 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 state tax return. The rate will vary depending on your overall taxable income for the year.
Our primary focus here is on businesses operating solely in Montana. 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 Montana, it may be subject to Montana 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.
