Delaware C-corp bookkeeping and franchise tax

Almost nobody operates in Delaware. Most US startups are incorporated there, and that alone creates a filing you cannot skip.

Delaware is not a location page in the way New York or Austin is. Nobody runs their company from Delaware. They incorporate there, and then owe Delaware something every year regardless of where the work happens.

Two methods, and the state quotes the wrong one

Delaware calculates franchise tax two ways and you pay the lower — but only if you file under it. The notice the state sends quotes the Authorized Shares figure, which for a venture-backed startup with a large authorised share count is wildly higher than the alternative.

$1,600Assumed Par Value method, same company
1 MarchDeadline for corporations

Same company, same year. The difference is which method you file under. Our Delaware franchise tax calculator runs both against your own numbers.

Why the books decide the answer

The Assumed Par Value method needs your total gross assets as reported on Schedule L of the federal Form 1120, and your issued share count. If the books are not closed and the balance sheet is not final, you cannot compute the cheaper method — so companies default to the expensive one out of time pressure rather than choice.

Instalments

Owe $5,000 or more and Delaware requires estimated payments through the year: 40% by 1 June, 20% by 1 September, 20% by 1 December, and the remainder by 1 March.

What we do for Delaware C-corps

Books closed early enough that the balance sheet supports the cheaper method, the 1 March deadline tracked, and the state filing handled alongside wherever you actually operate — New York, San Francisco, or Austin.

Frequently asked questions

We are a Delaware C-corp but operate elsewhere. Do we owe Delaware anything?+
Yes. Franchise tax and the annual report are owed for the incorporation itself, regardless of where you operate. You will also owe tax in the state where you actually do business — they are separate liabilities.
Why is our Delaware bill so much higher than expected?+
Because the state's notice quotes the Authorized Shares method by default. If you have a large authorised share count and modest assets, the Assumed Par Value method is usually far cheaper, but you have to file under it — Delaware does not switch you automatically.
What happens if we file late?+
Delaware charges a penalty plus monthly interest, and a corporation that does not file eventually loses good standing. That will hold up a financing or an acquisition at exactly the wrong moment.
