10 min readUpdated January 12, 2026

Overview

Delaware is the most popular state for incorporation in the United States, with over 60% of Fortune 500 companies incorporated there. Delaware's business-friendly laws, specialized Court of Chancery, and well-developed corporate law make it an attractive choice for businesses of all sizes.

This guide covers the compliance requirements for Delaware C-Corporations.

Key Compliance Requirements

1. Annual Report and Franchise Tax

Delaware corporations must file an Annual Report and pay franchise tax each year.

Due Date: March 1st (strict deadline - no automatic extensions)

Annual Report Information Required:

  • Names and addresses of directors
  • Names and addresses of officers
  • Principal place of business
  • Franchise Tax Calculation:

    Delaware offers two methods for calculating franchise tax. You pay the LOWER amount:

    Method 1: Authorized Shares Method

  • 5,000 shares or less: $175 minimum
  • 5,001 - 10,000 shares: $250
  • Each additional 10,000 shares: add $85
  • Maximum: $200,000
  • Method 2: Assumed Par Value Capital Method

    This method considers:

  • Total authorized shares
  • Total issued shares
  • Total gross assets
  • Formula: (Assumed Par Value x Authorized Shares) ÷ 1,000,000 x $400

    For most startups with high authorized shares but low assets, this method results in the minimum tax of $400.

    Filing Fees:

  • Annual Report filing fee: $50
  • This is in addition to the franchise tax
  • Example Calculations:

    *Startup Corporation A:*

  • 10,000,000 authorized shares (common for VC-backed startups)
  • 1,000,000 issued shares
  • $50,000 gross assets
  • Using Authorized Shares Method: Over $80,000

    Using Assumed Par Value Method: $400 (minimum)

    Pay: $400 + $50 filing fee = $450

    *Established Corporation B:*

  • 1,000 authorized shares
  • 1,000 issued shares
  • $5,000,000 gross assets
  • Using Authorized Shares Method: $175

    Using Assumed Par Value Method: $400

    Pay: $175 + $50 filing fee = $225

    Payment Methods:

  • Online at corp.delaware.gov (recommended)
  • Mail check to Delaware Division of Corporations
  • 2. Registered Agent

    Delaware corporations must maintain a registered agent in Delaware at all times.

    Requirements:

  • Must be a Delaware resident or a corporation authorized to act as a registered agent
  • Must have a physical street address in Delaware
  • Must be available during normal business hours
  • Registered Agent Fees:

  • Typically $50-$300 per year depending on provider
  • This is paid to your registered agent, not to the state
  • Changing Your Registered Agent:

  • File a Certificate of Change of Agent
  • Filing fee: $50
  • 3. Other State Filings

    Certificate of Amendment:

  • Required for any changes to Certificate of Incorporation
  • Filing fee: $200 minimum
  • Change of Principal Place of Business:

  • File amended Annual Report
  • No additional fee if done with regular Annual Report
  • Penalties for Non-Compliance

    Delaware takes franchise tax compliance seriously.

    Late Payment Penalties:

  • $200 penalty for late filing
  • 1.5% interest per month on unpaid tax
  • Corporation voids if not filed for 3 consecutive years
  • Voided Corporation:

    If your corporation voids, you cannot:

  • Conduct business
  • File lawsuits
  • Transfer property
  • Perform any corporate acts
  • Reinstatement:

  • File all past-due Annual Reports
  • Pay all past-due taxes, penalties, and interest
  • File Certificate of Renewal/Revival
  • Revival fee: $209 or more
  • Annual Compliance Calendar

    Delaware-Specific Advantages

    Court of Chancery

    Delaware has a specialized business court (Court of Chancery) that handles corporate disputes without juries. This leads to:

  • Faster resolution of disputes
  • More predictable outcomes
  • Extensive legal precedent
  • Business-Friendly Laws

  • Directors have broad discretion in business decisions
  • Strong protection for board decisions made in good faith
  • Flexible corporate structure options
  • Privacy

  • Delaware does not require disclosure of officer/director names in the Certificate of Incorporation
  • Shareholder names are not part of public record
  • No Corporate Income Tax for Out-of-State Business

  • Delaware corporations that operate entirely outside Delaware pay no Delaware corporate income tax
  • You may still owe tax in states where you actually do business
  • Common Mistakes to Avoid

    1. Using the Wrong Tax Calculation Method

    - Always calculate using BOTH methods and pay the lower amount

    - Many companies overpay by using only the Authorized Shares method

    2. Missing the March 1 Deadline

    - There is no grace period

    - Penalties begin immediately on March 2

    3. Letting Registered Agent Lapse

    - If your registered agent resigns, appoint a new one immediately

    - Legal documents may not be properly served without a registered agent

    4. Forgetting About Delaware When Operating Elsewhere

    - Even if you do all your business in California, you still have Delaware obligations

    - Delaware compliance is in addition to any state where you actually operate
