What's Next After Filing
Once your Corporation is officially formed, you'll want to complete these important steps:
- •Create Corporate Bylaws — Draft corporate bylaws that govern internal operations, including procedures for shareholder meetings, board of directors responsibilities, officer roles, voting rights, and other operational rules. Bylaws are not filed with the state but must be maintained at the principal office.
- •Hold Organizational Meeting and Issue Stock — Conduct an initial organizational meeting of the board of directors to adopt bylaws, elect officers, authorize issuance of stock, and handle other foundational corporate matters. Document the meeting with formal minutes and issue stock certificates to initial shareholders.
- •Obtain EIN and Fulfill Tax and Licensing Requirements — Obtain a Federal Employer Identification Number (EIN) from the IRS for tax purposes. Register for applicable South Dakota state taxes with the Department of Revenue and obtain any required business licenses or permits at the state or local level.
Advantages
- ✓South Dakota has no corporate income tax, no personal income tax, and no franchise tax, resulting in significant tax savings for shareholders and the corporation.
- ✓South Dakota offers strong asset protection and privacy laws, including favorable trust and corporate statutes that protect shareholder and director information.
- ✓The corporate structure provides strong limited liability protection, shielding shareholders' personal assets from corporate debts and legal judgments.
- ✓South Dakota is a business-friendly state with low filing fees, streamlined processes, and a stable legal environment, making it cost-effective to form and maintain a corporation.
- ✓Corporations can raise capital more easily than other entity types by issuing multiple classes of stock and attracting venture capital or institutional investors.
Considerations
- •Corporations are subject to more formalities than LLCs, including requirements to hold annual meetings, maintain detailed minutes, adopt bylaws, and follow strict governance procedures.
- •C-Corporations face potential double taxation at the federal level — once on corporate profits and again when dividends are distributed to shareholders — unless S-Corp election is made.
- •Corporations generally have higher administrative and compliance costs compared to sole proprietorships or partnerships, including ongoing registered agent fees and annual report obligations.
