As I understand it, if your tIRA to Roth conversion is landing you in the 15% tax bracket, it cannot be said to be "tax free". Your tax free conversion amount would be:
6,350 deduction +
4,050 exemption +
3,000 loss -
other taxable income
After that, you'd be paying 10% on the next $9,325 converted amount, and 15% beyond that.
