No, it is never too late to file taxes. It is possible that you will not be able to e-file your return and have to paper file the return.
In your case, this will not be a problem, but if a tax return is filed more than 3 years from the date it was due, any refund you may be entitled to from the IRS does not have to refund to you. If you are within the 3-year window, you will receive the refund, if the IRS determines you are entitled to the refund.
However, if you owe money whether you are 1 year late or more, you could (and most likely will) be assessed a Failure-to-File penalty and a Failure-to-Pay penalty along with interest from the date the tax return was due.
