Why would you elect to apply a refund to next year's tax bill?
Aside from the fear that you or a loved one will spend it frivolously, I'm hard pressed to come up with another reason.  If you'll owe money in the next tax year, you have the rest of the year to adjust your withholdings and/or make quarterly payments. As both my fellow PFers state, you're better off getting your money back. Better still, use it to pay off a high interest debt.
