Can a Alabama marriage tax estimate show both a bonus and a penalty?

Yes. The calculator can show either outcome depending on how the two incomes interact under federal and Alabama tax rules. Similar incomes can produce a different result from highly uneven incomes.

What does the marriage bonus or penalty number mean?

It is the difference between the modeled taxes for two separate single filers and the modeled taxes on a joint return. A positive difference means the joint return looks better in the estimate.

Should I change my W-4 based on this result?

You can use the result as a planning signal, but the actual withholding setup should still be reviewed on the current W-4 and in the context of the full household tax picture.

Why does the state route matter on a marriage calculator?

State income tax changes the combined tax outcome, so the same couple can see a different modeled bonus or penalty in different states.
