trouble getting decimal points

[cstudentc]

Hello, I'm having troubles getting an output. I want two decimal points in the output so for example:

Enter yearly income amount (0.0 to quit): $ 45000.00
The U.S. 1913 income tax = $450.00

When I do this however, it comes out $450 instead of $450.00

//tax
#include <iostream>
using namespace std;

int main()
{
	double income = 0.00;

	cout << "Enter yearly income amount (0.0 to quit): $  ";
	cin >> income;

	if (income > 0.00 && income <= 50000.00)
	{
		cout << "The U.S. 1913 income tax = " << income*0.01 << endl;
	}

	else if (income > 50000 && income <= 75000)
	{
		cout << "The U.S. 1913 income tax = " << income*0.02 << endl;
	}

	else if (income > 75000 && income <= 100000)
	{
		cout << "The U.S. 1913 income tax = " << income*0.03 << endl;
	}

	else if (income > 100000 && income <= 250000)
	{
		cout << "The U.S. 1913 income tax = " << income*0.04 << endl;
	}

	else if (income > 250000 && income <= 500000)
	{
		cout << "The U.S. 1913 income tax = " << income*0.05 << endl;
	}

	else if (income > 500000)
	{
		cout << "The U.S. 1913 income tax = " << income*0.06 << endl;
	}

	else
	{
		return 0;
	}

	return 0;
