I want to set up a journal which takes net operating income and multiplies it by the tax rate I choose in a given month - is this possible?

Hello James

In any journal you create it has to have a figure, so if you are looking to for example set up a monthly recurring journal with an amount and tax rate in,you would have to change the operating income, as it is not possible(other than using the payroll) to get journals to auto populate  and pull through information from another section such as income.
