Alabama NR Prorated exemption calculation

[cuadradog]

I had a small income ( $158) from a DST property located in Alabama (AL). I am an AL non resident

In a different post, I asked if I have to file a return for AL, the answer was:

You are required to file an Alabama (AL) return if as a nonresident your income is over the allowable prorated exemption (full year resident amounts are $3,000 for married filing jointly and $1,500 for single).  AL Instructions

I am still confused about how to calculate the prorated exemption?  

Let's say the total income is  $100,000  and the Alabama income is  $10

Would my prorated calculation be  100,000 /10 = 10,000    or  10/100,000 = 0.0001 ?

2. What number I need to use? Is it the total income or the taxable income?  In my return, those are 2 different numbers: the taxable income is the total income minus deductions.

1. Your calculation is correct.
2. You use your ratio of income from Alabama sources to your total income from all sources.

Please see the Form 40NR Booklet for more information.

Thanks for the answer. I apologize if I keep on this:

Let's say the total income is  $100,000  and the Alabama income is  $10

Would my prorated calculation be 

a.  100,000 /10 = 10,000   ?   

b. 10/100,000 = 0.0001 ?

It’s .0001.

Your standard deduction or itemized deductions, your personal exemption(s) and dependent exemption(s) have to be prorated by the ratio of your income from Alabama sources to your total income from all sources.

In calculating your taxable income, you'll deduct your prorated standard or itemized deductions, prorated personal exemptions and prorated dependent exemptions.
