What does a Delaware C-Corporation pay the state each year?

An annual report and franchise tax, due by 1 March. Under the authorized shares method the tax starts at US$175, plus a US$50 filing fee, and it rises with the number of authorized shares, so check the method that gives the lower figure. This is separate from our renewal, and we show it before each due date.
