Interactivity note: Always ask the user for missing inputs. If your agent has an

AskUserQuestion

tool (Claude Code, Cursor, etc.), prefer it — structured questions are easier for users to answer. Otherwise, ask in natural language.

• This skill does not download or execute any code.
• All portal interactions are performed by the user, guided step-by-step by the agent.
• If the user opts in to browser automation (Playwright via CDP), the agent may assist with portal navigation — but credit card and banking details must always be entered by the user directly.

• Annually before March 1 (C-Corps) or June 1 (LLCs/LPs/GPs)
• When your registered agent sends a reminder
• When you receive a notice from the Delaware Division of Corporations
• Portal hours: 8:00am-11:45pm ET only
• Scam warning: Delaware warns about deceptive solicitations. Legitimate notices come from the state or your registered agent only. Discard anything that asks you to pay through a non-official channel.

• Entity type: C-Corp or LLC/LP/GP
• Delaware Business Entity File Number (up to 9 digits)
• Registered agent name

• Total authorized shares by class and par value (e.g., 10,000,000 shares of Common Stock at $0.00001 par value)
• Total issued and outstanding shares as of December 31 of the tax year
• Total gross assets as of December 31 (from Form 1120 Schedule L, Line 15 — or estimated from bank balance + investments + receivables)
• Nature of business (brief description of how the company generates revenue)

• Officers: names, titles, addresses
• Directors: names, addresses

Shares <= 5,000:        $175 (minimum)
5,001 - 10,000:         $250
Each additional 10,000: +$85
Maximum:                $200,000

• First 10,000 shares: $250
• Remaining 9,990,000 shares = 999 increments of 10,000: 999 x $85 = $84,915
• Total: $250 + $84,915 = $85,165

Step 1: Assumed Par = Total Gross Assets / Total Issued Shares
Step 2: For each class of shares where assumed par >= stated par:
        use assumed par x number of authorized shares in that class
Step 3: For each class of shares where assumed par < stated par:
        use stated par x number of authorized shares in that class
Step 4: Sum all classes = Assumed Par Value Capital (APVC)
Step 5: Tax = (APVC rounded up to next $1,000,000 / $1,000,000) x $400
Step 6: Minimum tax: $400
Step 7: Maximum tax: $200,000

• Step 1: Assumed Par = $50,000 / 1,000,000 = $0.05
• Step 2: $0.05 >= $0.00001, so use assumed par: $0.05 x 10,000,000 = $500,000
• Step 4: APVC = $500,000
• Step 5: Round up to $1,000,000 -> 1 x $400 = $400

• $50 for non-exempt domestic corporations
• $25 for 501(c)(3) exempt corporations

Method 1 (Authorized Shares): $XX,XXX
Method 2 (Assumed Par Value):  $XXX
Recommended method:            Method 2
Filing fee:                    $50
Total due:                     $XXX + $50 = $XXX

1. Launch Chrome with remote debugging (see

   reference/ecorp-portal-playwright-notes.md

   for commands)
2. Connect via Playwright (see reference for CDP connection snippet)
3. Portal field reference: See

   reference/ecorp-portal-playwright-notes.md

   for:
   • All field selector IDs
   • Date field workaround (must use JS

     el.value =

     not Playwright

     .fill()

     )
   • State dropdown abbreviations (use

     value="NY"

     not

     label="New York"

     )
   • Director name fields (separate first/middle/last fields, NOT one name field)
   • APVC activation sequence
   • Session/eId behavior

1. Navigate: Open https://icis.corp.delaware.gov/ecorp/logintax.aspx
2. Login: Enter Business Entity File Number. Solve CAPTCHA (if the user shares a screenshot, the agent can try to read it). Click Continue.
3. Entity verification: Confirm entity name, registered agent, and registered office match your records.
4. Fill form fields (all on one page):
   • Stock info: Issued shares (per-class field, NOT the readonly total), gross assets, asset date (must == fiscal year end)
   • Address: Principal business address with state abbreviation
   • Nature of business: Select from dropdown (e.g., "Technology/Software")
   • Officer: First/middle/last name, title, address
   • Directors: Set total count, click "Enter Directors Info", fill first/middle/last name + address for each
   • Authorization: First/middle/last name, title, address
   • T&C checkbox: Must check

     chkCertify

     before continuing
5. Recalculate tax: Click "Recalculate Tax" button. Verify the displayed tax matches your calculation from Phase 2. If it still shows the Authorized Shares method amount, the asset date is probably wrong — fix it via JavaScript.
6. Review: Click "Continue Filing" to see the Review Copy. Verify all data.
7. Payment: Click "Proceed to Payment". The agent must stop here — credit card and banking details must be entered by the user. If tax exceeds $5,000, ACH payment is required.
8. Confirmation: After payment:
   • Click "Display Confirmation Copy" (

     onclick="downloadConfirmation();return false;"

     ) to save receipt PDF
   • Click "Email Confirmation Copy" to email the filed report (opens popup at

     Email.aspx

     , enter email address)
   • CRITICAL: "Once you leave this screen, you will no longer be able to obtain a confirmation copy" — save/email before navigating away
   • Record the Service Request Number from the URL:

     srNo=XXXXX

Ecorp_Confirmation_<ServiceRequestNumber>.pdf

• ~/Documents/Tax/Delaware/<EntityName>/

  on local disk
• A "Tax" or "Corporate Records" folder in cloud storage if available
• Keep the original filename — it contains the Service Request Number for future reference

undefined
