New to Java, please help with first Assignment

[Jason Marceau]

Hi All,

I am new to Java and need some help with my first assignment:

Assignment 1: Taxation Calculator
Specification
Write a program to calculate the tax of an employee. The program should
prompt for a salary and age, and work out the required tax from this data.
These two items will be whole numbers, however the resulting tax calculation
may be a floating-point number.
If the employee is aged 50 or over, their taxable income reduces by 10%.
Taxation Rates
The taxation rates and thresholds are the following:
Taxable Income Tax Calculation
$0 - $6,000 No tax
$6,001 - $21,600 17% on each $1 over $6000
$21,601 - $52,000 $2,652 plus 30% on each $1 over $21,600
$52,001 - $62,500 $11,772 plus 42% on each $1 over $52,000
$62,501 + $16,182 plus 47% on each $1 over $62,500
Sample Execution
For example, the tax calculation for an employee with a salary of $54,000 is:
11772 + (2000 * 0.42) = 12612
If this employee was over 50, their taxable income would be $48,600, and the
calculation would then be:
2652 + (27000 * 0.30) = 10752
The program, when run, might look as such:
Enter the employee’s taxable income: 54000
Enter the employee’s age: 52
Their tax payable is $10752.00

Here is my code:

else
taxPayable = annual_income;


// 1.) <$6000
if (annual_income<6000 )
taxPayable = 0;
else

// 2.) $6000 - $21,600
if (annual_income>6000 && annual_income <21600);
else
taxPayable = annual_income * 17/10;

// 3.) $21,600 - $52,000
if (annual_income>21600 && annual_income <52000)

taxPayable = (annual_income - 52000) * 30/100 + 2652;
else
// 4.) $52,001-$62,500
if (annual_income>52000 && annual_income<62500)

taxPayable = (annual_income - 52000) * 42/100 + 11772;
else

// 5.) >$62,500
if (annual_income>62500)
taxPayable = (annual_income - 52000) * 47/100 + 16182;
else
// display tax payable amount
System.out.print("Tax payable is:$ " + taxPayable);

}
}

Can someone please tell me what I doing wrong to get the wrong result please?

Thank you
