There is no way to have your 2016 tax return pay his back taxes. However, if you wait to file your 2016 return until after he files his 2015 tax return, they will keep what he owes out of your refund.
I would advise him to go back and file his 2015 taxes. If he owes anything and they process it before they process your return, then they will take enough of your refund to pay the back taxes. Here is the link to take you to the TurboTax products for 2015.

If you wait and file after your file your 2016 taxes, they will just send you a bill. At that time, you can either pay it (sometimes they will even waive the penalties if you ask politely) or set up a payment plan using the link below:
