    Help with if statement

    I need help with this program, I don't know what to do. I am not getting the amount of tax.
    /*This is program that displays the tax due over the amount of taxable income*/

    #include <stdio.h>

    int main()
    {
    float income=0, amount_of_tax=0;
    printf("Please enter the amount of taxable income: ");
    scanf("%d", &income);
    fflush(stdin);
    if (income < 750.00)
    amount_of_tax = .01 * income;
    else if (income < 2250.00)
    amount_of_tax = 7.50 + .02 * income;
    else if (income < 3750.00)
    amount_of_tax = 37.50 + .03 * income;
    else if (income < 5250.00)
    amount_of_tax = 82.50 + .04 * income;
    else if (income < 7000.00)
    amount_of_tax = 142.50 + .05 * income;
    else
    amount_of_tax = 230.00 + .06 * income;

    printf("The amount of tax due is: $%.2f\n", amount_of_tax);

    return 0;
    }

    >scanf("%d", &income);
    income is a float, %d is for ints -- use %f.
    fflush(stdin) is not standard.
    Code tags make code easier to read.
