I think the answer depends on whether or not you live in a community property state. If you live in a community property state, I think the standard deduction should be allocated 50/50. However, if you do not live in a community property state, I recommend allocating the standard based on total income for you and your spouse. I sounds like you have more income than your spouse, and assuming this fact is correct, more of the standard deduction should be allocated to you. This is just my opinion. The injured spouse allocation can be complicated. You may want to consult with a tax professional for a more detailed analysis of your particular situation.
