Program isn't printing correctly

Question

I believe my program is still going through the if statements after it is declared invalid. It should print invalid filling status or invalid exemption status on the same line w

Answer 1

You might consider doing the following after the scanf:

fillingStatus = toupper(fillingStatus);

Then only test for the uppercase characters:

fillingStatus == 'S'

You need to fix your 'ifs' as suggested and print output like the following. It won't be quite right until you've fixed the 'ifs', though.

if (taxExemptions > 12  || taxExemptions < 0) {
    printf("\n %d \t**** Invalid exemptions status ****", taxpayerId);
} else {
    taxAmount = taxableIncome * taxRate;
    printf("\n %d \t %.2f \t\t %.2f \t %15.2f",taxpayerId,taxableIncome,taxRate,taxAmount);
}

The more I look at this code, the more I'm confused too. What should the tax rate be for someone with taxableIncome of 1 and fillingStatus == 'S'. I think it's going to be 0.31, since it's less than 20000. Probably not what you're going for. I think you're missing some 'else if' statments.
