Double check your formulas as they look wrong. They look as if you'll always subtract a number bigger than the income.

Also, your if statements are wrong. Something like this:

Code:

---

  if(m>109250 && m<=166500);
  taxes = (m- 166500)*0.305 +24393.75;

---

will be interpreted by the compiler as this:

Code:

---

  if(m>109250 && m<=166500)
      ; // this empty statement will be run or not depending on the boolean test in the if above
  taxes = (m- 166500)*0.305 +24393.75; // this line will always be run

---

Instead, get rid of the semi-colon at the end of the if statement and always enclose any block or loop such as your if blocks, in curly braces:

Code:

---

  if(m>109250 && m<=166500)  // [color="red"]*** no semi-colon here ***[/color]
      taxes = (m- 166500)*0.305 +24393.75;
  }

---

But again, this formula looks wrong since m is always going to be less than or equal to 166500, and if you subtract 1665500 from m, it will always be less than or equal to 0.
