When you formed your business, you likely chose your entity structure based on liability protection, operational flexibility or your accountant’s recommendation. That decision continues to shape your tax obligations, and as your Minnesota business matures and revenue grows, it’s worth revisiting whether your current structure still serves your financial interests.
How sole proprietorships and partnerships are taxed
As a sole proprietor or partner, you report your business income on your personal tax return. That income is subject to self-employment tax at 15.3%, plus Minnesota’s income tax rates that can reach up to 9.85%. Limited partners may qualify for different treatment under certain exemption rules.
For businesses with strong profit margins, this combination can add up quickly. Once your income exceeds the Social Security wage base, you are still on the hook for the Medicare portion on every additional dollar you earn.
How LLCs give you more flexibility
The LLC structure offers something many business owners overlook: the ability to choose how the IRS taxes you. By default, the IRS taxes a single-member LLC like a sole proprietorship, but you can elect S corporation or C corporation treatment by filing the appropriate form with the IRS.
Electing S corporation status lets you divide your income between a salary and distributions. You only pay payroll taxes on the salary portion, which can mean meaningful savings. However, your salary needs to reflect what someone in your role would reasonably earn — something the IRS watches closely.
How S corps and C corps are taxed differently
C corporations face double taxation. The business pays federal corporate tax at 21%, and then shareholders pay tax again when profits are distributed as dividends. Minnesota adds a 9.8% corporate tax on top of that. S corporations, on the other hand, avoid this by passing income directly to shareholders, similar to how a partnership works.
Both structures may also owe Minnesota’s minimum fee if their combined property, payroll and sales cross certain thresholds. Despite the double taxation, C corp status can still make sense for businesses that plan to reinvest profits for growth or are positioning for a future acquisition, where tools like equity compensation and multiple share classes become useful.
Aligning structure with your business reality
If your income has grown substantially, you are bringing in partners or you are thinking about succession, your current entity may no longer be the most tax-efficient choice. Because entity selection involves complex tax and legal considerations unique to your business, professional guidance can help you make decisions that protect both your interests and your bottom line.
