Had an apartment in alabama but work payments from georgia based company. i have to file in both states for state taxes?

Where are you physically located when you are working?  If you are in GA physically working, then yes, you would need to file a return for both states.

In general, your home state will tax all in come from all sources.  Then you will file a nonresident return for the states that you do not reside in, but you visit for work and earn money in.  When you file, you will fille out your nonresident states first.  Then you will fill out your resident state, claiming a credit for taxes paid to the nonresident states on your home state return.  You may or may not still end up owing money to your resident state depending on whether or not their tax rate is higher or lower than your nonresident state.  If the non resident state had a higher tax rate than your resident state, your credit will be limited to the amount of tax you would have paid to your resident state.  They will not give you a refund of the taxes you paid to the nonresident state. 

Multiple States

File Non Resident State Return

If you are physically working in Alabama, then you would not need to file a GA return.  It does not matter where the payments come from if you  never step foot in that state.  It matters where the work is performed.
