Why the notice is so high

Every Delaware corporation pays an annual franchise tax with its annual report, due March 1. Delaware allows two ways to compute it and says to "use the method that results in the lesser tax", but the notice it sends is usually based on the first one, the Authorized Shares method, which only looks at how many shares your charter authorizes. A typical startup authorizes 10,000,000 shares, which under that method is $85,165. Founders who pay the notice as printed overpay by tens of thousands of dollars.

The second way, the Assumed Par Value Capital method, uses your gross assets and issued shares. For the same startup with 9,000,000 shares issued and $500,000 of assets it comes to the $400 minimum. To use it, you file the annual report yourself (or through your incorporation service) and enter your issued shares and total gross assets.

Worked example: 10,000,000 authorized shares

The same startup as above, run through both methods: 10,000,000 authorized shares at $0.00001 par, 9,000,000 issued, $500,000 of gross assets.

The two methods, step by step

• Authorized Shares: $175 for 5,000 shares or fewer, $250 for 5,001 to 10,000, then $85 for each additional 10,000 shares or part of 10,000. 100,000 shares costs $1,015; 10,000,000 costs $85,165.
• Assumed Par Value Capital: divide total gross assets (the "total assets" line on Form 1120, Schedule L) by total issued shares, to six decimals: that is the assumed par. Multiply it by the authorized shares of every class whose par value is below it; add the authorized shares of any class with a higher par times that par. The result is the assumed par value capital. The tax is $400 per million or part of a million, prorated below $1,000,000, with a $400 minimum.
• Both methods are capped at $200,000 a year. Large corporate filers pay more and are not covered here.

As assets grow, so does the tax: the same share structure with $3,000,000 of assets after a seed round owes $1,600, and with $12,000,000 after a Series A, $5,600. From $5,000 a year Delaware wants estimated payments: 40% by June 1, 20% by September 1, 20% by December 1 and the rest by March 1.

Deadlines and penalties

The annual report and the tax are due March 1 for the previous year; the report filing fee is $50. Missing it costs a $200 penalty plus 1.5% interest a month, and a corporation that fails to pay or file for a full year has its charter declared void (8 Del. C. § 510). A company that existed for only part of the year owes a prorated tax for the portion of the year it was in existence (8 Del. C. § 503(d)).
