Trying to get some clarification on deduction splitting between spouses when filing separately. I've looked at other questions about this but the answers are all over the place.
Lets just use mortgage interest as an example.
Both of our names are on the mortgage, it is paid out of a joint account. I am listed on the mortgage as the primary.
1. Do we have to split this 50/50 or can it be all applied to just one of us or any other ratio?
2. If it can all be applied to just a single person, does the other person still need to input the information into the form and just say the amount is ZERO?
3. Does the above in 1 & 2 apply for anything else we have jointly in our names (PMI, property taxes, personal property taxes)
4. How does this affect home office deductions? If I apply X amount of the home deductions to me, I assume I put only those amounts into the home office deduction part correct?
Anything else one should know about doing this I am overlooking or missing?
