What do you mean by "doesn't work"?
1. Fails to compile?
2. Crashes, while running?
3. Unexpected results?


Recheck the "how to call a function" from http://www.cplusplus.com/doc/tutorial/functions/

You do call one function correctly, but what do you do with its return value?
The other line is not a function call. It is a declaration.


PS. Fix the code tags in your post.

while it is legal to have the same name used all over, it is confusing to read.

you probably meant

double AI = annualincome();
calculations(AI);


where you have

annualIncome();
calculations(double annualIncome);

or possibly

calculations(annualincome());
