Can you add in previous student loan interest paid but not filed in previous tax years to the current tax year?

[Howard1948]

No.  You can only include student loan interest paid in 2016 on a 2016 Federal income tax return.  To take the student loan interest deduction for a prior year, you would have to file an amended tax return using Form 1040-X for that year.

Question on this, if I never filled taxes before and never claimed the interest, can I still claim past years interests?

No, if you are filing a 2019 tax return, you can only claim student loan interest that was paid in 2019 on that return.

If you have student loan interest that was paid in prior years which you did not claim, you may be able to file an amended return for those years to deduct the interest on the prior year returns. 

If you have not yet filed those prior year returns, then you can claim the interest that was paid in those prior years on that year's return.

You mentioned that you have not filed taxes before and never claimed the interest.  If you did not have income for the prior years, then filing a return to claim the interest is not beneficial.  If you did have income but you just have not filed the returns, then you can claim the student loan interest as part of your return.

One other thing---if you were claimed as a dependent on someone else's tax return for any of those past years you cannot claim the student loan interest for those years.
