My boyfriend and I bought a house together this year, should only one of us claim this on our taxes?

If you both are on the title and on the mortgage then you would enter on each tax return the amount of interest and real estate taxes you each paid.

Mortgage interest and real estate taxes are itemized deductions on Schedule A.  The total of all your itemized deductions on Schedule A must be greater than the standard deduction for your filing status to have any tax benefit.

Standard deductions for 2023

Single - $13,850 add $1,850 if age 65 or older
Married Filing Separately - $13,850 add $1,500 if age 65 or older
Married Filing Jointly - $27,700 add $1,500 for each spouse age 65 or older
Head of Household - $20,800 add $1,850 if age 65 or older

You pretty much have a choice. One can claim it all or you can split it. It's usually best if only one claims it, allowing the other to use the standard deduction.

You have to meet the rules, which are:

1. You are legally obligated to pay it
2. You actually pay it. Paying from a joint account where you made sufficient deposits to cover the payments will usually meet this standard. However, paying from your own account would be a stronger audit defense.
