Taxes and GDP, where do these come in in the formula? We all know that the formula for GDP I'd given by

GDP = C + I + G + NX

I would like to know, whether I am right in deducing that when consumers and industry pay taxes, or when there are import and export taxes I suppose, these do not increase the value of C and I in the equation. Instead, these increase the value of G, provided that the money supplied in taxes to the government is spent.

Is this correct?

Thanks.
In this equation:

GDP = C + I + G + NX

Taxes come from a combination of C+I but are offset by an increase in G.

Any government taxation which is not spent is an investment, so remains part of I.
