not sure what the semantic implications are of the statement above......sounds like you don't want to include taxes as spending.......even though you might write a check in April for the balance. Or maybe you count the Apr check as spending and don't consider withholding as spending.
You might have the same issue w/ withholding........do you count withholding for medical insurance as an expense or not? Seems to me that it doesn't matter as long as you account for it somewhere .......don't leave it out and don't double count it.
One reason why it might be useful to include the withholding for taxes and medical insurance as explicit spending items is that if you FIRE, they will become real spending items and you might forget that you have to pay them if they are buried in the net income.
