Answer to Question 1

In the IS equation, government purchases are a component of autonomous spending, no different than autonomous consumption, investment, and net exports. From the perspective of producers, a customer is a customer. Taxes, clearly, are not an expenditure. Taxes affect expenditure by reducing disposable income and, thus, consumption. Since only a fraction of disposable income is spent for consumption  a fraction measured as the marginal propensity to consume  each dollar of taxes corresponds to a fraction of a dollar taken from consumption expenditure.
