Arkansas taxes - short term capital gains for "Primary/joint income" or "Spouse's Income Status Only"
My wife and I made 100,000 in short term capital gains. In Arkansas, we can file jointly or individually with the individually (same form) giving the better refund overall. However, for the the short term capital gains, if I put the entire 100,000 in the Primary/Joint Income we save $300 in taxes versus splitting it with 50,000 in Primary/Joint Income column and 50,000 in "Spouse's Income Only column." Can I keep it all in the "Primary/Joint Income" column to save taxes or do I need to split it? Strangely, my spouse makes less so I can't understand why taxes are higher if split it.
