How do I calculate the required amount of each franchise & excise tax estimated tax payment?

The Worksheet for Calculation of Quarterly Estimated Franchise, Excise Tax Payments is available for calculating the required quarterly payments.  Taxpayers may make four equal installments under the standard method.  Alternately, they may elect to use the annualized income method for this calculation.  The worksheet and related instructions provide the calculation for both methods.
