Delaware C-Corps are chosen by 68% of venture-backed startups for investor-friendly Delaware General Corporation Law (DGCL). Online formation takes 1-2 hours but proper structure prevents $50,000+ legal costs during Series A fundraising.
Why Delaware
Delaware Chancery Court has 230+ years of corporate law precedent. Judges are corporate law specialists, not generalists. Cases resolved in months, not years.
Investor preference: 92% of VCs require Delaware C-Corp for Series A funding. Acquiring companies prefer Delaware targets for predictable legal outcomes.
C-Corp vs LLC
C-Corp allows unlimited shareholders, preferred stock for investors, stock options for employees. LLC has pass-through taxation but can't issue stock options or raise venture capital effectively.
Choose C-Corp if raising venture capital, planning IPO, or issuing stock options to team. Choose LLC for small business with profits distributed to owners (avoids double taxation).
Converting LLC to C-Corp before fundraising triggers taxable event for founders. Start as C-Corp if venture funding likely within 2-3 years.
Name Availability
Check Delaware Division of Corporations database before filing. Name must be "distinguishable" from existing Delaware entities.
Use Delaware entity name search. Free, instant results. Check phonetic variations and common misspellings.
Similar name rejections: Delaware rejects names "likely to be confused" with existing entities even if spelling different. "TechVenture" vs "Tech Ventures" both rejected.
Naming Rules
Must end with "Corporation", "Incorporated", "Company" or abbreviation ("Corp.", "Inc.", "Co."). Cannot use "LLC", "LP", "Ltd" unless actually that entity type.
Cannot use: "Bank", "Trust", "Insurance" without state authorization. "United States", "Federal", "National" imply government affiliation (rejected).
Formation Process
Reserve company name: $75 via Division of Corporations, holds name 120 days. File Certificate of Incorporation: $89 state filing fee + $15 county fee, 1-2 hours processing if filed online.
Appoint registered agent in Delaware: $50-300/year, required to receive legal correspondence. File initial report: Due within 30 days if filing after January 1, no fee.
Obtain EIN from IRS: Free, instant online via IRS website. Adopt bylaws and issue stock: Within 30 days recommended, no filing required.
Costs Breakdown
State filing fee: $89 + $15 county = $104 total. Registered agent: $50-300/year (required). Franchise tax: Minimum $175/year (due March 1 annually).
Formation service (optional): $0-500 depending on provider (Stripe Atlas $500, Clerky $0 + filing fees). Legal counsel for structure: $2,000-8,000 if complex cap table.
USPTO trademark: $250-$350 per class. Initial stock issuance (83(b) election filing): $0 IRS fee but $500-2,000 lawyer recommended.
Total minimum: $400-1,500 first year DIY. Add $5,000-15,000 for lawyer-structured formation with proper founder vesting and stock plan.
Authorized Shares
Specify number of authorized shares in Certificate of Incorporation. Typical: 10,000,000 shares (10M) for early-stage startup. Franchise tax calculated on authorized shares if using "Authorized Shares Method".
Higher share count provides flexibility for future fundraising but increases minimum franchise tax. 10M shares = $400 franchise tax. 100M shares = $4,000+ franchise tax.
Share Structure
Authorize both common stock (founders, employees) and preferred stock (investors). Typical split: 8M common, 2M preferred authorized at formation.
Founders typically receive 50-80% of initial common stock (5-8M shares). Reserve 10-20% for employee stock option pool (1-2M shares). Investors buy preferred stock in Series A/B/C rounds.
Authorized shares trap: Increasing authorized shares later requires shareholder vote and amended Certificate - costly during fundraising. Authorize enough shares upfront (10-20M) for 3-5 years of growth.
Delaware Franchise Tax
Due March 1 annually. Two calculation methods: Authorized Shares Method or Assumed Par Value Capital Method. Company chooses lower amount.
Authorized Shares Method: $175 minimum (up to 5,000 shares) + $250 per 10,000 shares above 5,000. Assumed Par Value Method: Based on assets and issued shares (often lower for startups).
Tax Examples
10M authorized shares: $175-400/year depending on method. 100M authorized shares: $2,500-5,000/year. Early-stage startups typically pay $175-400/year.
Registered Agent
Must maintain Delaware registered agent with physical Delaware address. Agent receives legal notices, annual reports, subpoenas.
Cannot use PO Box or Delaware mailbox service. Registered agent services: $50-300/year. Popular providers: Harvard Business Services ($50/year), Corporation Service Company ($300/year).
DIY Registered Agent
Can appoint yourself if you have Delaware physical address (not viable for most non-Delaware founders). Missing legal notice costs $5,000-50,000 in default judgments.
Don't skip registered agent to save $50/year - liability exposure too high. Choose reputable provider that digitizes documents and alerts you immediately.
Agent service matters: Cheap registered agents ($25-50/year) may not forward urgent legal notices promptly. Use $100-300/year service that scans and emails documents same-day.
Stock Issuance
Issue stock to founders within 30 days of incorporation. Use Restricted Stock Purchase Agreement with vesting schedule (typically 4 years, 1-year cliff).
File 83(b) election with IRS within 30 days of stock issuance to avoid taxation on vesting. Missing 83(b) deadline costs founders $10,000-100,000+ in taxes over vesting period.
83(b) Election
Allows founders to pay tax on stock value at issuance ($0.001/share = $10 total tax) instead of at vesting (when worth $1-10/share = $10,000-100,000 tax).
Must file: Within 30 days of stock grant, send copy to IRS by certified mail, attach copy to tax return. No exceptions or extensions - missing deadline can't be fixed.
Foreign Qualification
If operating primarily in another state (office, employees), must register as foreign corporation in that state. Costs $100-500 per state plus annual reports.
California: $800/year minimum franchise tax for foreign corps. New York: $25 filing + registered agent in NY. Texas: $750 filing fee.
When Required
Physical office or warehouse in state: Required. Employees working in state: Required. Remote employees in multiple states: Generally not required.
Selling products to customers in state: Not required. Attending conferences or sales meetings: Not required. Threshold: "Substantial continuous business activity" triggers qualification.
Don't foreign qualify in California unless necessary - $800/year minimum tax even with $0 revenue. Delaware + remote team avoids foreign qualification.
Common Mistakes
Authorizing too many shares: Increases franchise tax from $175 to $2,000+/year unnecessarily. Not filing 83(b) election: Costs founders $10,000-100,000 in taxes over vesting.
Skipping registered agent: Miss legal notices, face default judgments costing $5,000-50,000. Using cheap formation service without lawyer review: Cap table mistakes cost $50,000+ to fix during Series A.
Not adopting bylaws: Creates governance disputes between founders. Foreign qualifying in California unnecessarily: Pay $800/year minimum tax with no benefit.
Post-Formation
Annual franchise tax: Due March 1, $175-400 for most startups. Annual report: Due with franchise tax, no separate fee.
Corporate formalities: Hold annual board meetings, document major decisions in minutes, maintain stock ledger. Federal tax filing: C-Corp files Form 1120 annually, pays 21% corporate tax on profits.
State tax filing: If foreign qualified or doing business in other states, file state corporate returns. Quarterly payroll taxes: If employees, file federal Form 941 quarterly.
