Purchased Home 2021 with unmarried partner

[Isabella_27]

My partner and I purchased a home in 2021 in CA. We are joint tenants, both names are on the title, and both of us pay the mortgage (alternating months.) My partner paid the property tax. We have to file separately, how can we claim deductions? Are there other details for us to consider in order to be able to maximize our deductions?

Each of you will claim the mortgage interest and property taxes that you actually paid in 2021.
