Having formed entities in both states for clients, here's my honest comparison for 2026:
Delaware wins for: Venture-backed startups (VCs expect it), companies planning IPO, complex corporate governance, well-developed case law (Court of Chancery). Annual cost: ~$400-$600 (franchise tax + registered agent).
Wyoming wins for: Small businesses, real estate holding LLCs, privacy-focused owners, low-cost maintenance. Annual cost: ~$52 (annual report) + registered agent if needed. No state income tax, no franchise tax.
The biggest misconception: forming in Delaware doesn't save you from your home state's taxes or registration requirements. If you live in California and form a Delaware LLC, you STILL owe California's $800 franchise tax AND must register as a foreign LLC in CA. So you're paying double.
