Delaware Franchise Tax: The Complete C-Corp Founder's Guide (2026)

If you incorporated in Delaware and you opened the mail one February to find a tax bill for $85,000, you are not alone. It is one of the most common shocks founders experience in their first year of running a C-corp, and it is almost always a calculation choice — not a real tax liability.

This guide explains what Delaware franchise tax is, how the two methods work, and why electing the right method usually means paying $400 instead of tens of thousands.

What Delaware franchise tax actually is

Every corporation incorporated in Delaware — whether or not it has revenue, employees, or operations there — owes an annual franchise tax to the state. It is the fee for being a Delaware entity, not a tax on income. The bill is due March 1 along with the corporation's annual report.

Two things to keep separate:

• Franchise tax itself, calculated under one of two methods (below).
• Annual report fee: a flat $50 for non-exempt domestic corporations.

Both are filed and paid together through the Delaware Division of Corporations.

The two methods, and why this matters

Delaware lets you compute your franchise tax under either of two methods. You owe the lesser of the two. The catch: the state's default bill is always calculated under the more expensive method (Authorized Shares), so if you accept the default and pay, you are leaving money on the table — sometimes a lot.

Method 1 — Authorized Shares Method

This method counts how many shares your charter authorizes you to issue, regardless of how many you have actually issued or whether anyone owns them.

The bracket is unforgiving for any corporation authorized to issue more than a few thousand shares. A typical Silicon Valley standard incorporation with 10,000,000 authorized shares produces a tax of $85,165. Five million authorized shares produces around $42,665.

Method 2 — Assumed Par Value Capital Method

This method weighs the relationship between your gross assets, your issued shares, and your authorized shares. For a normally-capitalized startup, it almost always comes out far cheaper.

The math, step by step:

1. Assumed par per share = total gross assets ÷ total issued shares (carry to six decimal places).
2. For each class of stock: contribution = (greater of assumed par or stated par) × authorized shares.
3. Assumed Par Value Capital = sum of all class contributions.
4. If APVC > $1,000,000, round it up to the next whole million. Tax = (APVC in millions) × $400. Otherwise, tax = (APVC ÷ 1,000,000) × $400, with a $400 floor.

The minimum is $400. The maximum is $200,000.

Use the calculator to plug in your numbers and see both methods side by side.

Why founders get hit by the default

Here is the typical first-year experience. A founder uses Stripe Atlas, Clerky, or another incorporation service. The default charter authorizes 10,000,000 shares of common stock at $0.0001 par value. The company spends its seed money on engineering, has $500,000 in the bank in February, and 7,000,000 shares issued to the founders.

Delaware mails a bill for $85,165. The founder panics.

But under Method 2:

• Assumed par per share = $500,000 ÷ 7,000,000 ≈ $0.071429
• Assumed Par Value Capital ≈ $0.071429 × 10,000,000 ≈ $714,286
• That's under $1 million, so the tax is the $400 minimum.

Total owed = $400 tax + $50 report fee = $450. Same company, same year, $84,715 saved by checking a different box on the annual report.

How to elect the lesser method

You elect Method 2 by entering the inputs (issued shares, total gross assets, par values per class) on the annual report at the Delaware Division of Corporations' filing portal. The state recomputes the tax. You pay the lesser.

You do not need to file an amendment, hire a lawyer, or do anything special — the choice is a field on the annual report form. The reason most founders pay the default is that they don't realize the second method exists or that the initial bill is overstated.

Multi-class share structures

The calculator above assumes a single class of common stock. After a priced round, you will have at least two classes (Common + Series Seed/A Preferred), and the Assumed Par Value Capital math runs per class. For each class:

• If the class's stated par value is less than the assumed par value, use assumed par × authorized shares of that class.
• If the class's stated par value is greater than or equal to the assumed par value, use stated par × authorized shares of that class.

Sum across classes for total APVC. The same rounding and rate then applies.

If your preferred shares were issued at a high par value, this branch can move you out of the cheap end of the curve. A real CPA or your transfer agent should run the full calculation after every priced round.

Estimated payments and penalties

• Estimated payment threshold: If your prior-year tax was $5,000 or more, Delaware requires quarterly estimates: 40% by June 1, 20% by September 1, 20% by December 1, balance by March 1.
• Late penalty: $200 flat plus 1.5% interest per month on the unpaid balance.
• Not in good standing: Stay delinquent and Delaware will mark the entity not in good standing, which can block financing rounds, bank operations, and any other filing requiring state authorization.

What to do this year

If your annual report is still ahead of you, run your numbers through the calculator and elect the lesser method when you file. If you already paid the default bill in a previous year and it was substantially overstated, you can file an amended annual report with the corrected Method 2 calculation and request a refund of the overpayment.

If you have a priced round, the multi-class math is non-trivial — verify with your CPA before filing.
