Can I deduct the interest on a student loan I co-signed for my ex-husband if I am the one making the payment?

You can deduct student loan interest if:

• You paid interest on a qualified student loan in tax year 2015

• You are legally obligated to pay interest (ie. you are a co-signer) on a qualified student loan

• Your are not filing Married Filing Separate

• Your Modified Adjusted Gross Income is less than a specified amount which is set annually, and

• You or your spouse, if filing jointly, cannot be claimed as dependents on someone else's return.
