The corporate excise tax itself serves a dual function — taxing both net income at 8.00% and tangible property or net worth at $2.60 per $1,000. The minimum corporate excise tax is $456 per year. Financial institutions are subject to a separate financial institution excise tax in lieu of the standard corporate excise tax.
