Post-Incorporation Checklist for Delaware C-Corps
You just incorporated your Delaware C-Corp. Congratulations! But the work isn't done yet. This comprehensive checklist covers everything you need to do in the first 30 days after incorporation to set your startup up for success.
Immediate Actions (Days 1-3)
1. Secure Your Formation Documents
Your incorporation package should include:
- Certificate of Incorporation — The official document filed with Delaware
- Corporate Bylaws — Rules governing how your company operates
- Initial Board Resolutions — Authorizing key actions like opening bank accounts
- Stock Certificates or digital records for founder shares
- EIN Confirmation Letter (SS-4) from the IRS
SparkLaunch Tip: All formation documents are automatically stored in your SparkLaunch Document Vault, accessible anytime from your dashboard.
2. File Your 83(b) Election
This is critical if you received restricted stock. You have exactly 30 days from the stock grant date to file.
Why it matters: An 83(b) election lets you pay taxes on the current (low) value of your shares, rather than the potentially much higher value when they vest.
How to file:
- Complete IRS Form 83(b) — include company name, shares received, grant date, fair market value
- Mail to the IRS within 30 days of grant (certified mail recommended)
- Keep a copy for your records
- Provide a copy to your company
Warning: Missing this deadline is irreversible and can cost you hundreds of thousands in taxes later.
3. Open a Business Bank Account
Keep personal and business finances separate from day one.
Required documents:
- Certificate of Incorporation
- EIN Confirmation Letter
- Board Resolution authorizing account opening
- Government ID for signers
Recommended banks for startups: Mercury, Brex, Silicon Valley Bank, First Republic
Week 1: Cap Table & Equity Setup
4. Set Up Your Cap Table
Your cap table tracks who owns what percentage of your company. Get this right from the start.
Key components:
- Authorized shares (typically 10M for startups)
- Issued founder shares (with vesting schedules)
- Option pool allocation (typically 10-20%)
- Any SAFEs or convertible notes
SparkLaunch Feature: Our free Cap Table tool automatically tracks founder shares, SAFEs, and calculates dilution scenarios. Set it up in minutes.
5. Issue Founder Stock
Each founder should:
- Sign a Stock Purchase Agreement
- Pay for shares (can be nominal, e.g., $0.0001/share)
- Sign an IP Assignment Agreement (transferring any prior work to the company)
- Set up vesting schedule (typically 4 years with 1-year cliff)
6. Adopt Equity Incentive Plan (Optional)
If you plan to hire employees and grant stock options:
- Adopt a Stock Incentive Plan (board approval required)
- Create a stock option grant template
- Reserve shares for the option pool (typically 10-20%)
Week 2: Legal & Compliance
7. Register as a Foreign Corporation (If Applicable)
If you operate in a state other than Delaware, you likely need to "foreign qualify" there.
States that typically require this: California, New York, Texas (if you have employees, office, or significant business there)
Documents needed: Certificate of Good Standing from Delaware, completed foreign qualification application
8. Obtain Business Licenses
Depending on your industry and location:
- General business license from your city/county
- Industry-specific licenses (if applicable)
- Sales tax permit (if selling taxable goods/services)
9. Set Up Registered Agent
Your Delaware registered agent receives legal documents on your company's behalf.
Included with SparkLaunch: Your first year of registered agent service is included with our $399 incorporation package.
Week 3: Operations & Finance
10. Set Up Accounting System
Choose an accounting solution and establish good practices:
- QuickBooks, Xero, or Wave for bookkeeping
- Separate business credit card for expenses
- Expense tracking from day one
11. Obtain Business Insurance
Consider these policies:
- General Liability — Protects against third-party claims
- D&O Insurance — Directors and Officers liability (important before fundraising)
- E&O Insurance — Errors and Omissions for professional services
12. Create Operating Procedures
Document key processes:
- Expense approval workflow
- Board meeting schedule (at least annually for Delaware corps)
- Record-keeping protocols
Week 4: Growth Preparation
13. Prepare Investor Materials
If you plan to fundraise:
- Update your pitch deck
- Organize your data room with due diligence documents
- Set up investor CRM to track conversations
SparkLaunch Feature: Our Investor CRM (Startup plan) helps you track investor conversations, meeting notes, and pipeline stages.
14. Set Up Company Communications
- Company email domain (G Suite or Microsoft 365)
- Team communication (Slack, Teams)
- Company website with legal pages (privacy policy, terms of service)
15. Schedule Annual Compliance
Set calendar reminders for:
- Delaware Franchise Tax — Due March 1 annually (minimum ~$400 for most startups)
- Delaware Annual Report — Due March 1 ($50 filing fee)
- Annual Board Meeting — Required by Delaware law
- Registered Agent Renewal — Usually annual
