Before going into the details, here is your quick checklist for starting an S corp in Minnesota.
An S corporation is a federal tax classification under Subchapter S of the Internal Revenue Code. It is not a standalone business structure.
An eligible Minnesota LLC or C corporation files IRS Form 2553 to request S corp status. Once approved, the business does not pay federal corporate income tax on its profits. Instead, income and losses pass through directly to shareholders' personal tax returns, where they are taxed at the individual level.
To start an S corporation in Minnesota, you first form a business entity, either an LLC or a C corporation, through the Minnesota Secretary of State. After your entity is active, you file Form 2553 with the IRS within the required deadline.
Minnesota automatically accepts your S corp status once the IRS approves it. S corporations doing business in Minnesota then file Form M8 with the Minnesota Department of Revenue each year.[3]
Minnesota's personal income tax rates, which reach up to 9.85%, mean that shareholders pay state income tax on their share of S corp pass-through income on their individual Minnesota returns.[4]
Filing Form 2553 on time is one of the most important steps in the process. Miss the window and your election will not take effect until the following tax year.
| Scenario | Deadline | Effective Tax Year |
|---|---|---|
| Existing business, calendar year | March 16, 2026 | 2026 |
| New business formed January 15, 2026 | April 1, 2026 | 2026 |
| New business formed June 1, 2026 | August 15, 2026 | 2026 |
| Filed during prior year (2025) | December 31, 2025 | 2026 |
For existing calendar-year businesses, IRS rules require you to file Form 2553 by the 15th day of the third month of the tax year. In 2026, March 15 falls on a Sunday, so the deadline shifts to March 16, 2026.
New businesses have 2 months and 15 days from their formation date to file. Miss that window, and you will need to request a late election with a reasonable cause statement, or wait until the following tax year for the election to take effect.
If you wanted your S corp election to take effect at the start of 2026, you could have filed Form 2553 at any point during calendar year 2025. For all 2026 filings, use the deadlines above.
LLC members who do not elect S corp status pay self-employment tax (15.3%) on all net profits from the business. With an S corp election, you split your income between a W-2 salary and distributions. Only your salary is subject to payroll taxes. Distributions are not, which can produce meaningful savings at higher income levels.[5]
As an S corp owner, you pay yourself a reasonable salary for the work you do in the business. Any remaining profits can then be taken as distributions. Distributions are not subject to self-employment taxes, which allows you to keep more of what your business earns while staying fully compliant with IRS requirements.
The Tax Cuts and Jobs Act allows qualifying S corp owners to deduct up to 20% of their qualified business income (QBI) from their personal tax returns under Section 199A. Distributions from an S corp may qualify for this deduction, reducing your federal taxable income further. W-2 salary payments do not qualify, so structuring your compensation correctly matters.[6]
Minnesota offers a Pass-Through Entity (PTE) tax election that allows S corporations to pay Minnesota income tax at the entity level on behalf of their shareholders. For qualifying businesses, this can produce a deduction at the entity level that partially offsets the federal $10,000 cap on state and local tax (SALT) deductions. Not every Minnesota S corp will benefit from the PTE election, but it is worth reviewing with a tax professional if your shareholders pay significant Minnesota income tax.[7]
Electing S corp status does not change your LLC's legal structure, operating agreement, or management setup. Your members run the business exactly as before. You keep the same liability protection and operational control. The only change is how the IRS treats your business income, not how Minnesota recognizes your legal entity.
A C corporation pays federal income tax on its profits at the corporate level. When those profits are distributed to shareholders as dividends, shareholders pay income tax a second time on their personal returns. An S corp election eliminates this second federal tax layer. Profits pass through directly to shareholders and are only taxed once at the individual level.
S corp shareholders can deduct business losses on their personal tax returns, up to the amount of their basis in the company. C corporation shareholders have no equivalent benefit; losses stay at the corporate level. This pass-through of losses is particularly valuable during startup years or periods of lower revenue.
C corporations that retain earnings beyond reasonable business needs may be subject to the IRS accumulated earnings tax. S corporations avoid this penalty because profits pass through to shareholders each year rather than accumulating at the entity level. This gives Minnesota S corp owners more flexibility in how they manage earnings without triggering additional federal tax exposure.
C corporations file Form 1120 and manage corporate-level taxes separately from their shareholders' personal returns. S corporations file Form 1120-S, and each shareholder receives a Schedule K-1 reporting their share of income or loss. Many business owners find the S corp pass-through structure more manageable compared to maintaining separate corporate and personal federal tax layers.
Selling a C corporation can trigger taxation at two levels: the corporation pays tax on the gain from an asset sale, and shareholders pay again on distributions. An S corp election can allow a sale to be structured in a way that avoids this double layer of tax on the gain, potentially increasing after-tax proceeds when Minnesota business owners plan an exit or ownership transfer.
An S corp is a tax classification, not a standalone entity. You must have an active Minnesota LLC or C corporation registered with the state before you can file your IRS election. Here is how the full process works.
If you do not already have a registered Minnesota business entity, your first step is to form one. Choose the structure that fits your business goals. An LLC is simpler to maintain and works well for most small business owners. A C corporation is a better fit if you need to attract investors or issue multiple classes of stock.
Forming an LLC before your S corp election is the most common path. Minnesota LLC filings go through the Minnesota Secretary of State. Here are the key steps:

Already have an active Minnesota LLC or C corporation? Skip directly to Step 2.
Once your Minnesota LLC or C corporation is active, you file IRS Form 2553, the Election by a Small Business Corporation, to officially request S corp tax treatment from the IRS. This single form changes how the federal government taxes your business income from that point forward. Minnesota automatically accepts the election once the IRS approves it. No separate filing is required with the Minnesota Secretary of State or Department of Revenue.
Form 2553 collects the following information:
All shareholders must sign the consent portion of the form before it is submitted. An unsigned form will be rejected by the IRS.
You can submit Form 2553 by mail or fax. There is no filing fee.
Faxing is typically faster than mailing. Keep your fax confirmation receipt. The IRS will send a CP261 acceptance notice to confirm your S corporation election. If your election is not accepted, you will receive a letter explaining the issue.
If you file after the standard deadline, you may still be eligible for a late election under IRS Revenue Procedure 2013-30, provided you meet certain requirements. See the section below on what to do if you miss the deadline.
Once your S corp election takes effect, IRS rules require you to pay yourself a W-2 salary if you work in the business. This is not optional. Owner-employees of S corporations cannot simply take all their compensation as distributions.
The IRS expects your salary to reflect what someone performing similar work, in the same industry, and in the same region would typically earn. There is no fixed formula, but the IRS flags S corps where owner salaries appear unusually low relative to distributions.[8]
Setting your salary too low risks the IRS reclassifying distributions as wages, which would make them subject to payroll taxes. Setting it too high means you are paying more in payroll taxes than necessary.
Payroll adds ongoing administrative requirements to your business. Many Minnesota S corp owners work with a payroll provider or accountant from day one to keep their compliance records accurate.
Every S corporation files its own federal tax return each year using IRS Form 1120-S. This return is due by March 16, 2026 for calendar-year S corporations (March 15 falls on a Sunday in 2026). Each shareholder receives a Schedule K-1 showing their individual share of income or loss, which they use to complete their personal federal tax returns.[9]
S corporations doing business in Minnesota must file Form M8, S Corporation Return, with the Minnesota Department of Revenue each year. Form M8 is due by March 15 for calendar year filers, March 16, 2026 since March 15 is a Sunday.[10]
Before completing Form M8, you must first complete your federal Form 1120-S and supporting schedules. Minnesota bases its state return on federal taxable income with state-specific modifications applied. Each shareholder also receives a Minnesota Schedule KS reflecting their share of state pass-through income, which they report on their Minnesota Form M1 individual income tax return.
Minnesota's personal income tax rates range from 5.35% to 9.85%, depending on income level and filing status. Shareholders pay Minnesota income tax on their share of S corp pass-through income at these rates.
In addition to pass-through taxation at the shareholder level, Minnesota S corporations may be subject to the Minnesota minimum fee, which is paid by the entity itself and calculated on Form M8. The minimum fee applies based on the combined total of the S corporation's Minnesota-sourced property, payroll, and sales or receipts. The thresholds are adjusted annually for inflation.
For the 2026 tax year:
Most small and mid-sized Minnesota S corporations with less than $970,000 in combined Minnesota property, payroll, and sales will owe no minimum fee. Confirm your specific obligation by completing Form M8 or consulting with a Minnesota tax professional.
Minnesota allows S corporations to elect the Pass-Through Entity (PTE) tax, which lets the entity pay Minnesota income tax on behalf of its qualifying shareholders. For shareholders who itemize their federal deductions and are affected by the $10,000 SALT cap, a PTE election may produce a net tax benefit. The PTE election is optional and should be evaluated based on your shareholders' individual circumstances.
Once your S corp is active, there are ongoing requirements to stay in good standing. Here is what applies specifically to Minnesota S corporations.
S corporations doing business in Minnesota file Form M8 by March 15 for calendar year filers (March 16 in 2026). The return reports income, modifications, and any minimum fee owed. If you need more time to file, Minnesota grants an automatic six month extension to September 15, 2026. The extension covers the paperwork only, any tax or minimum fee owed is still due by the original March 15 deadline.
If your combined total of Minnesota property, payroll, and sales exceeds the state-defined threshold, your S corp may owe a minimum fee calculated on Form M8. The fee is graduated and increases as your totals rise, up to a capped amount for larger entities. S corps below the threshold do not owe a minimum fee. This fee is paid at the entity level, separate from the individual income tax paid by shareholders on their share of pass-through income.
Your underlying Minnesota LLC or corporation must file an annual renewal with the Minnesota Secretary of State by December 31 each year. The renewal is an informational filing confirming your current registered agent, registered office address, and principal executive officer. There is no filing fee. Failing to file can result in your entity losing good standing, which may affect your ability to do business, open accounts, or enter contracts. If your entity becomes inactive, reinstatement requires paying a fee.[9]
S corporations file Form 1120-S with the IRS each year by March 15 for calendar-year filers (March 16 in 2026). This return reports total income, deductions, and credits, and issues Schedule K-1 to each shareholder. Missing the deadline without an extension can result in IRS penalties calculated per shareholder per month. A six-month extension is available by filing IRS Form 7004.
The IRS requires S corp owner-employees to receive a reasonable salary for work performed in the business. This salary is subject to payroll taxes. Minnesota's competitive professional job market means salary benchmarks in many industries are well-established. An accountant familiar with your field can help you set a compensation level that meets IRS standards without overpaying payroll taxes.
S corp owners who work in the business must be on payroll. Federal employment taxes are deposited quarterly using Form 941. You must also register with the Minnesota Department of Revenue for state income tax withholding and with the Minnesota Unemployment Insurance program. Quarterly withholding returns and annual W-2 reporting are required for all employees, including owner-employees.
Minnesota corporations are required to hold annual shareholder meetings and keep records of meeting minutes, shareholder and director actions, and financial statements. Minnesota LLCs do not have the same formal meeting requirements, but maintaining organized records is important for any S corp regardless of entity type.
Missing the IRS filing deadline does not automatically end your options. The IRS provides a path for late elections under Revenue Procedure 2013-30, as long as certain conditions are met.
To qualify for late election relief, your business must meet the following:
If you miss the March 16, 2026, deadline for the current tax year, your S corp election may still apply to 2026 if you file with a valid, reasonable cause explanation.
For LLCs filing a late election, you may also need to file IRS Form 8832 (Entity Classification Election) alongside Form 2553. This step is required when an LLC needs to first elect corporate tax treatment before the S corp designation can apply.
Late elections involve additional IRS review. Many business owners work with a formation service or tax professional to make sure the paperwork is complete and the reasonable cause statement is properly written before submission.
Circumstances change. There may come a point when S corp status no longer fits your business, and revoking the election is the right move.
To revoke the election, shareholders holding more than 50% of the company's stock must file a written revocation statement with the IRS service center where Form 2553 was originally submitted. There is no IRS form for this. It is a letter sent to the same Kansas City, MO address used for Form 2553.
File the revocation on or before March 16 of the current tax year (for calendar-year businesses), and it takes effect for that year. File it after that date, and the revocation takes effect the following year.
Once an S corp election is revoked, the entity generally cannot re-elect S corp status for five years without IRS consent.
If any of these situations apply to your Minnesota business, it is worth reviewing your tax designation with a qualified Minnesota accountant before filing a revocation.
