When , US government decides to increase income taxes we will see following changes.
Savings :
An increase in income tax will reduce givernmets budget defict. This will prevent government from filling that tax out of taking loans from banks in the form of T bills. It will leave national savings for more investment by the private sector.
Investment
Increase in income tax will result in reduced demand by consumers which will discourage business firms to invest more .
Real interest rate:
Tax increase will result in reduced demand this would bring down aggregate demand curve. When the economy is working above potential GDP level this reduced demand will ease inflationary pressure and thus,we will see reduced real interest rate.
On the other hand if the economy is already functioning way below potential GDP level reduced aggregate demand will not have much effect on price level thus, we won't see any considerable change in real interest rate.
Capital Flow :
Capital will flow out of consumers to government. The amount of government deficit will reduce and it can also result in government surplus .
Now, to prevent any changes in the economy due to increased tax rate what we can do is increase government expenditure by the same amount. When money out of consumers pocket is spent by government at the same proportion ,net change in economic variables will remain same as before. Here, instead of taking loans out of security government will increase expenditure our of tax income. On,the other hand consumers will reduce their expenditure, but government expenditure will offset this due to same level of aggregate demand in the economy . Investment will remain same due to no net change in consumption demand in the market.
