Delaware franchise tax: two methods, and why one bill is 100× the other

In short

What is the Delaware franchise tax?

Delaware franchise tax is an annual tax every Delaware corporation pays for the privilege of being incorporated there. It is not a tax on income or revenue. Domestic corporations file an annual report and pay by 1 March, using either the authorized shares method or the assumed par value capital method.

Why the first bill is a shock

A newly incorporated Delaware C corporation typically authorises ten million shares of common stock at a par value of a hundred-thousandth of a dollar. That is the standard startup template, and it exists for good reasons: enough share capacity for a decade of financings and option grants, and a par value low enough that issuing shares does not require meaningful consideration.

Delaware’s default calculation, the authorized shares method, keys off exactly that number. Ten million authorized shares generates a tax in the tens of thousands of dollars. Founders open the notice, see a five-figure demand from a state they have never visited for a company with no revenue, and assume a mistake has been made. No mistake has been made — they are simply looking at the wrong method.

Method one: authorized shares

The authorized shares method looks only at how many shares the certificate of incorporation authorises. It ignores how many are issued, what the company is worth, and whether it has any assets at all. Delaware publishes the brackets: 5,000 shares or less is the $175 minimum, 5,001 to 10,000 shares is $250, and each additional 10,000 shares or portion thereof adds $85.

The "or portion thereof" is worth reading twice. Authorising 10,000,001 shares costs the same as authorising 10,010,000. It also means the schedule is linear above 10,000 shares, at $85 per ten thousand, which is why the number gets large quickly.

Method two: assumed par value capital

The alternative method brings two additional facts into the calculation: how many shares are actually issued, and the corporation’s total gross assets. Delaware directs filers to the total assets reported on the corporation’s federal Form 1120, Schedule L, for the fiscal year ending in the calendar year covered by the report. The rate is $400 per million or portion of a million of assumed par value capital, and the minimum under this method is $400.

The assumed par value capital calculation, using Delaware’s own published example

Delaware’s example: total gross assets $1,000,000, issued shares 485,000, and authorized shares of 1,000,000 at $1.00 par plus 250,000 at $5.00 par.

  1. Divide gross assets by issued shares

    $1,000,000 ÷ 485,000 = $2.061856. This is the assumed par value, carried to six decimal places.

  2. Apply the assumed par to classes whose stated par is lower

    The $1.00 par class has 1,000,000 authorized shares and a stated par below the assumed par, so it is valued at the assumed par: 1,000,000 × $2.061856 = $2,061,856.

  3. Apply the stated par to classes whose stated par is higher

    The $5.00 par class has 250,000 authorized shares and a stated par above the assumed par, so it is valued at its stated par: 250,000 × $5.00 = $1,250,000.

  4. Add the classes together

    $2,061,856 + $1,250,000 = $3,311,856 of assumed par value capital.

  5. Round up and apply the rate

    Assumed par value capital over $1,000,000 rounds up to the next million, so $3,311,856 becomes $4,000,000. Divided by 1,000,000 and multiplied by $400, the tax is $1,600.

Two structural features of that calculation explain why it usually helps a startup. Assets divided by issued shares is a very small number when a company has raised little and issued many shares, and the rounding is to the next million of assumed par value capital rather than to the next dollar. A pre-seed company with a few hundred thousand dollars in the bank lands at or near the $400 floor.

The annual report fee is charged separately. Illustrative only — file using Delaware’s own calculation.

The last row is the one that stops this being a rule of thumb. A company with a small authorised block and a large balance sheet can pay more under the assumed par value capital method than under the authorized shares method. The methods are alternatives to be compared, not a default and a fix.

Large corporate filer status is not a startup concern. It applies to corporations with a class or series of stock listed on a national securities exchange that also meet consolidated revenue and asset criteria set out in the Delaware Code, and it fixes the annual tax at $250,000 rather than the $200,000 cap. Check the statute and the Division’s guidance rather than assuming a threshold.

Two other things sit alongside the tax. The annual report itself asks for the corporation’s principal place of business, its directors, and one officer — information that has to be current. And a Delaware corporation must maintain a registered agent in the state, which is a separate service with its own fee, unrelated to the franchise tax.

Consequences of not filing compound. Beyond the penalty and monthly interest, a corporation that stays delinquent loses good standing, which surfaces immediately in a financing or acquisition when counsel orders a certificate. Restoration involves paying everything owed for every year missed.

What this means when you authorise shares

The franchise tax is a real cost of authorising shares you are not using, but only under one of the two methods, and only if you cannot use the other. Because the assumed par value capital method usually produces a far smaller number for an early-stage company, the tax is a weak reason on its own to authorise fewer shares. Governance and financing mechanics are stronger ones.

What the tax does reward is accurate records. The assumed par value capital method needs issued share counts by class and stated par values by class, matched to a gross assets figure from the federal return. Those come out of the stock ledger and the balance sheet. A company whose issued share count is uncertain cannot use the cheaper method with confidence.

Frequently asked questions

When is the Delaware franchise tax due?
All active domestic corporation annual reports and franchise taxes for the prior year are due annually on or before 1 March. Corporations owing $5,000 or more pay estimated tax in instalments during the year: 40 percent by 1 June, 20 percent by 1 September, 20 percent by 1 December, and the balance by 1 March.
Why is my Delaware franchise tax bill so high?
Almost always because it was computed under the authorized shares method, which looks only at the number of shares your certificate of incorporation authorises. Ten million authorized shares produces $85,165 under that method. Entering your issued share count and total gross assets on the annual report lets Delaware compute the assumed par value capital method, which for most early-stage companies is far lower.
How do I reduce my Delaware franchise tax?
By filing under whichever of the two published methods produces the lower figure, which requires entering issued shares and total gross assets on the annual report. The assumed par value capital method charges $400 per million or portion of a million of assumed par value capital, with a $400 floor. Reducing authorised shares is a separate corporate action with its own consequences.
What is the minimum Delaware franchise tax?
$175 under the authorized shares method and $400 under the assumed par value capital method. The annual report filing fee is charged separately: $50 for a non-exempt domestic corporation and $25 for an exempt domestic corporation.
What is the maximum Delaware franchise tax?
$200,000 under either method. Corporations that meet the statutory large corporate filer criteria — including having a class or series of stock listed on a national securities exchange — have their annual tax fixed at $250,000 instead.
What happens if I file the Delaware annual report late?
Delaware charges a penalty of $200 plus interest at 1.5 percent per month on tax and penalty. Continued non-filing costs the corporation its good standing, which shows up the moment a buyer or investor orders a certificate.
