Many Montana business owners start with a simple structure. They form an LLC, open a business bank account, begin serving clients, and focus on growing revenue. Then, at some point, the question comes up.
“Should my LLC elect S-Corp status?”
It often appears during tax season, when profits are stronger than expected, and the tax bill feels larger than it should. The idea of reducing self-employment taxes becomes appealing, but the mechanics of how LLCs and S-Corps work can be confusing.
Understanding the difference can help you structure your business more efficiently as it grows. In this guide, we explain how an LLC vs S-Corporation in Montana works, where the real tax differences appear, and when an S-Corp election may make sense.
What An LLC Is In Montana
An LLC is one of the most common business structures used by small business owners across Montana. It protects the owner’s personal assets from business liabilities and allows income to pass directly through to the owner’s personal tax return.
By default, the IRS treats LLCs in one of two ways, depending on ownership.
- A single-member LLC is taxed as a sole proprietorship. The business income is reported on the owner’s personal return.
- A multi-member LLC is usually taxed as a partnership, where profits and losses pass through to each owner.
In both cases, the business itself generally does not pay federal income tax. Instead, the income flows to the owners.
Montana follows this same framework. The income from your business passes through to your personal Montana tax return and is taxed at the individual level.
Because LLCs are flexible and relatively simple to maintain, they are often the natural starting point for many Montana entrepreneurs.
What An S-Corporation Is
An S-Corporation is not a business entity. It is a tax election available to certain businesses under the Internal Revenue Code.
A business must first exist as either an LLC or a corporation. The owner can then elect S-Corp taxation by filing Form 2553 with the IRS.
The legal structure of the business does not change; what changes is how income is treated for tax purposes.
Like an LLC, an S-Corp benefits from pass-through taxation. Profits typically flow through to the owner’s personal tax return.
However, an important difference appears in how the owner is paid. Owners who actively work in the business must pay themselves a reasonable salary through payroll. After that, the salary is paid, and additional profits can be distributed to the owner as shareholder distributions.
Those distributions are where the main tax difference occurs.
The Biggest Tax Difference: Self-Employment Taxes
For many business owners, the discussion about LLC versus S-Corp ultimately centers on self-employment taxes.
Under an LLC structure, the entire profit of the business is generally subject to self-employment tax. This tax funds Social Security and Medicare, and is currently about 15.3%. If a business earns $150,000 in profit, that entire amount may be subject to self-employment tax, in addition to regular income tax.
An S-Corp changes how that income is treated because the owner is considered both a shareholder and an employee; they must take a reasonable salary through payroll. Payroll taxes apply to that salary. Any remaining profits can then be distributed to the owner. These distributions are not subject to self-employment tax, but are still liable for income tax.
Since Montana begins its tax calculation with federal taxable income, many federal tax decisions carry through to the state return as well. This means the largest financial difference between an LLC and an S-Corp usually does not come from Montana income taxes. Instead, it comes from how federal law treats payroll taxes and self-employment taxes on business income.
LLCs vs S Corps: Administrative Differences
Tax savings are only one part of the decision. An S-Corp also introduces additional administrative responsibilities.
A standard LLC structure is relatively simple. The business files its annual report with the Montana Secretary of State, maintains financial records, and reports income on the owner’s personal return.
Once an S-Corp election is made, the business must run payroll for the owner’s salary. This includes payroll tax filings, withholding requirements, and issuing a Form W-2.
The business must also file an S-Corporation tax return using Form 1120-S. Each owner receives a Schedule K-1 that reports their share of the business income.
For some businesses, these requirements are manageable. For others, the added complexity may outweigh the potential tax savings.
