Unlike traditional law firms, CORPIUS combines legal expertise with technology to deliver fast, affordable, and reliable US business services. Whether you are a non-resident in another country or a US citizen starting your first business, CORPIUS guides you from company formation through long-term compliance. Founded in New York, CORPIUS serves clients from over 50 countries. The platform supports multiple languages (English, Spanish, Arabic, Russian) and accepts global payment methods. **Key differentiators:** - No SSN required for non-US residents to form an LLC or Corporation - Same-day processing available for most formation services - Registered agent service included in all formation packages - Direct EIN application to the IRS on your behalf - Ongoing annual report and compliance reminders - US bank account guidance for non-residents --- ## Service: LLC Formation **What it is:** A Limited Liability Company (LLC) is the most flexible and popular US business structure. It protects personal assets from business liabilities, passes taxes through to the owner (avoiding double taxation), and requires minimal formalities compared to corporations. **What CORPIUS provides:** - Articles of Organization filing in any US state - Operating Agreement (single-member or multi-member) - Registered Agent service (1 year included) - EIN (Employer Identification Number) application - Company documents and digital storage - Compliance calendar and annual report reminders **Best states to form an LLC:** Delaware (privacy, flexibility), Wyoming (low costs, no state income tax), Florida (no personal income tax), Texas (large market, no state income tax). **Cost:** Starting from $149 + state filing fees. State fees vary: Wyoming ($100), Delaware ($90), Florida ($138.75). **URL:** https://corpius.net/services/llc --- ## Service: C-Corporation Formation **What it is:** A C-Corporation is a separate legal entity owned by shareholders. It is the preferred structure for venture-capital-backed startups because it allows unlimited shareholders, multiple stock classes, and no restriction on foreign investor ownership. **What CORPIUS provides:** - Articles of Incorporation in your chosen state (Delaware recommended for startups) - Corporate Bylaws - Initial Board Resolutions - Stock issuance documentation - Registered Agent service (1 year included) - EIN application **Why Delaware?** Over 65% of Fortune 500 companies and most VC-backed startups incorporate in Delaware due to its established corporate law, the Court of Chancery, and investor familiarity. **Tax note:** C-Corps pay a flat 21% federal corporate income tax. Dividends paid to shareholders are taxed again (double taxation). However, C-Corps can retain earnings at the corporate level and offer stock options (ISOs) to employees. **URL:** https://corpius.net/services/c-corporation --- ## Service: S-Corporation Formation **What it is:** An S-Corporation is a tax election (not a separate entity type) that allows a corporation or LLC to pass income, losses, deductions, and credits through to shareholders, avoiding double taxation. S-Corp status is particularly valuable for small business owners who pay themselves a salary and want to reduce self-employment tax. **Requirements:** Max 100 shareholders, all must be US citizens or permanent residents, only one class of stock allowed. **Tax savings example:** If your business earns $150,000 profit and you pay yourself a reasonable salary of $80,000, only the $80,000 is subject to self-employment tax (15.3%). The remaining $70,000 passes through as a distribution, saving approximately $10,710 in SE tax. **URL:** https://corpius.net/services/s-corporation --- ## Service: Nonprofit 501(c)(3) Formation **What it is:** A 501(c)(3) organization is a tax-exempt nonprofit recognized by the IRS for charitable, educational, religious, scientific, or literary purposes. Donations to 501(c)(3) organizations are tax-deductible for donors. **What CORPIUS provides:** - Articles of Incorporation (nonprofit) - Conflict of Interest Policy - Bylaws - Form 1023 or 1023-EZ preparation for IRS tax-exempt status - Registered Agent service - EIN application **Timeline:** IRS approval typically takes 3–6 months for Form 1023, or 2–4 weeks for 1023-EZ (for organizations expecting under $50,000/year in gross receipts). **URL:** https://corpius.net/services/nonprofit --- ## Service: Green Card Lottery (DV Program) **What it is:** The Diversity Visa (DV) Lottery is a US government program that makes 55,000 permanent resident visas (Green Cards) available annually to people from countries with historically low rates of immigration to the United States. **What CORPIUS provides:** - Professional review of eligibility - Photo compliance check (NIST standards) - Accurate form completion to avoid disqualification - Submission tracking and confirmation - Guidance for winners on next steps (DS-260, interview preparation) **Eligibility:** Must be from an eligible country (nationals of countries that sent more than 50,000 immigrants to the US in the past 5 years are ineligible, including Mexico, India, China, Philippines, El Salvador, Dominican Republic, Cuba, Vietnam, Haiti, Jamaica, South Korea, Brazil, Colombia, Guatemala, Honduras, Canada, UK (except Northern Ireland), Ecuador, Peru). **Cost:** The DV Lottery application itself is free through the US government.

There is no US citizenship or residency requirement to form an LLC. CORPIUS specializes in helping non-US residents form LLCs without an SSN. An ITIN or foreign passport is sufficient. **Q: Do I need a US address to form an LLC?** A: No. CORPIUS provides a registered agent address in your chosen state as part of all formation packages. **Q: How long does LLC formation take?** A: Processing typically takes 3–10 business days depending on the state. Expedited options are available in most states. **Q: What is an EIN and do I need one?** A: An EIN (Employer Identification Number) is a federal tax ID for your business, similar to a Social Security Number but for entities. You need an EIN to open a US business bank account, hire employees, and file business taxes. CORPIUS applies directly to the IRS on your behalf. **Q: Can I open a US business bank account as a non-resident?** A: Yes, though it requires the right documentation. CORPIUS provides a guide on opening business bank accounts without an SSN, including online bank options like Mercury, Relay, and Brex. **Q: What is the difference between an LLC and an S-Corp?** A: An LLC is a legal entity type. An S-Corp is a tax election that an LLC or corporation can make. Many small business owners form an LLC and then elect S-Corp taxation to reduce self-employment taxes once revenue exceeds ~$50,000/year. **Q: Is CORPIUS a law firm?** A: CORPIUS is a legal technology company. We provide document preparation and filing services. For complex legal matters, we recommend consulting with a licensed attorney. --- ## Blog: Recent Articles (March 2026) 1. **How to Start an LLC in the USA in 2026** — Step-by-step guide for entrepreneurs and non-residents covering state selection, filing, EIN, and bank account setup. https://corpius.net/blog/how-to-start-an-llc-in-the-usa-in-2026-the-definitive-step-by-step-guide-for-entrepreneurs-and-non-residents 2. **LLC vs S-Corp vs C-Corp: Complete 2026 Guide** — Comparison of all three structures for taxes, liability, and growth potential. https://corpius.net/blog/llc-vs-s-corp-vs-c-corp-complete-2026-guide-to-choosing-the-best-business-structure-for-taxes-and-growth 3. **Best States to Form an LLC in 2026: Delaware vs Wyoming vs Florida** — Detailed comparison including filing fees, annual costs, privacy, and tax implications. https://corpius.net/blog/best-states-to-form-an-llc-in-2026-delaware-vs-wyoming-vs-florida-full-comparison-guide 4. **How Much Does It Cost to Start an LLC in the US?
