FAQ

Wisconsin Corporation questions.

Should I form my Wisconsin corporation as a C-Corp or S-Corp?
Most Wisconsin corporations start as C-Corps (default federal tax treatment). S-Corp is a federal election (Form 2553) you file later, typically when net profit crosses $60-80k. For venture-backed startups, C-Corp is required: S-Corp cannot have institutional investors, non-US shareholders, or multiple share classes. We file the Wisconsin corporation; you can elect S-Corp anytime by filing Form 2553.
What is the difference between forming an LLC and a corporation in Wisconsin?
LLCs are simpler (no shares, fewer formalities, pass-through tax by default). Wisconsin corporations have shareholders, a board of directors, officers, bylaws, board minutes, and double taxation by default. Corporations are the standard structure for raising venture capital because investors require preferred stock, ESOPs, and other corporate-specific instruments LLCs cannot provide.
Do I need bylaws for my Wisconsin corporation?
Yes. Wisconsin corporations are governed internally by bylaws (board structure, officer roles, meeting requirements, voting rules) plus the Articles of Incorporation filed with the Wisconsin Department of Financial Institutions. We include Wisconsin-appropriate bylaws with every formation, along with initial board minutes and a corporate governance binder.
How many shares should my Wisconsin corporation authorize?
Standard for a new C-Corp: 10,000,000 authorized shares of common stock with a small percentage actually issued to founders. The 10M structure leaves room for an option pool (typically 10-20%) and future preferred stock issuances in financing rounds. We file the 10M authorized share structure by default; you can specify a different number.
What is QSBS and does my Wisconsin corporation qualify?
Qualified Small Business Stock (IRC Section 1202) lets shareholders exclude up to $10M (or 10x basis) of capital gains on qualifying C-Corp stock held more than 5 years. Wisconsin C-Corps qualify if they meet the active business test (80% of assets used in qualified trade) and the gross asset test (under $50M at issuance). We preserve QSBS eligibility from day one.
Do I need to issue founder stock with vesting?
Highly recommended. Wisconsin founder stock without vesting means a co-founder who leaves after 6 months keeps 100% of their shares. With standard 4-year/1-year-cliff vesting, the company can reclaim unvested shares. We issue founder stock with vesting and prepare Section 83(b) election forms (due to IRS within 30 days of issuance).
When should my Wisconsin corporation elect S-Corp status?
S-Corp election (IRS Form 2553) can save self-employment tax when net profit crosses ~$60-80k. Restrictions: 100 shareholders max, US individuals only (no entities, no non-resident aliens), single class of stock. If you plan to raise venture capital, stay C-Corp. Our service fee for filing Form 2553 is $99.
