Calculate Delaware franchise tax using the assumed par value method. Save thousands versus the default authorized shares method. Step-by-step.
By Omer Aydin ·
The Delaware franchise tax assumed par value calculation method is the single most overlooked tax optimization available to startup founders, and misunderstanding it costs thousands of companies tens of thousands of dollars every March. If your Delaware C-Corp authorized 10 million shares at $0.0001 par value (a standard setup for VC-backed startups), the default "Authorized Shares Method" produces a tax bill exceeding $85,000. The assumed par value method, by contrast, often brings that same company's bill down to the $400 minimum.
Delaware offers two calculation methods for franchise tax, and the state defaults to whichever produces the higher number unless you explicitly elect otherwise. This guide walks through the math, the filing mechanics, and the timing traps that catch first-time founders.
| Factor | Authorized Shares Method | Assumed Par Value Method |
|---|---|---|
| Inputs needed | Number of authorized shares only | Authorized shares + issued shares + total gross assets |
| Typical result for a 10M-share startup | $85,165 | $400 (minimum) |
| Best for | Companies with few authorized shares | Startups with large share pools and low asset bases |
| Filing complexity | Simple (one number) | Requires balance sheet data |
The Delaware franchise tax assumed par value calculation works by dividing your total gross assets (as reported on your federal tax return) by total issued shares, then multiplying that figure by total authorized shares. The result determines your tax bracket. For early-stage companies with minimal assets but large authorized share counts, this method almost always produces a dramatically lower figure.
You need three data points from your most recent federal tax return (Form 1120):
Divide total gross assets by total issued shares. If the result is less than the lowest par value stated in your charter, use that par value instead.
Formula: Assumed Par = Total Gross Assets ÷ Total Issued Shares
Multiply the assumed par value by total authorized shares.
Formula: Taxable Capital = Assumed Par × Total Authorized Shares
Delaware charges $400 per $1,000,000 of taxable authorized capital (or fraction thereof), with a $400 minimum and $200,000 maximum.
Consider a seed-stage startup with:
Authorized Shares Method: The first 10,000 authorized shares cost $250. Each additional 10,000 shares (or fraction thereof) costs $85. For 10,000,000 shares: $250 + (999 × $85) = $85,165.
Assumed Par Value Method: $150,000 ÷ 8,000,000 = $0.00001875 assumed par. Since this is below the stated par of $0.0001, we use $0.0001. Taxable capital = $0.0001 × 10,000,000 = $1,000. Tax = $400 (minimum).
The difference: $84,765 saved by choosing the correct calculation method.
The Delaware franchise tax is due March 1 each year for C-Corps. The annual report and tax payment must be filed together through the Delaware Division of Corporations portal. Late filing triggers a $200 penalty plus 1.5% monthly interest.
Critical timing issues founders miss:
Lovie's formation platform automatically tracks your authorized shares, issued shares, and gross asset figures. When franchise tax season arrives, the system calculates both methods and files using whichever produces the lower bill. No spreadsheet gymnastics, no accidentally paying $85,000 when you owe $400.
For founders who already have a Delaware C-Corp, Lovie's compliance tools flag the March 1 deadline 60 days in advance and pre-populate the assumed par value calculation from your cap table data.
Delaware does not automatically refund overpayments. You must file an amended annual report selecting the assumed par value method and request a refund. The Division of Corporations processes refund requests within 4 to 8 weeks, but only for the current tax year.
No. Delaware LLCs pay a flat $300 annual tax regardless of assets, income, or share structure. The assumed par value method applies exclusively to corporations (C-Corps and S-Corps).
Technically no, but accuracy matters. If your gross assets figure is wrong, Delaware can reassess the tax. Lovie's automated system pulls directly from your financial records, eliminating manual calculation errors.
Total gross assets means the figure reported on Line 15 of Schedule L (Form 1120). This includes cash, accounts receivable, inventory, investments, property, and any other assets before depreciation or liabilities are subtracted.
