Hi Wrenches, Since we’re on the topic of the ITC, I have another question someone might be able to help with. Assuming that a system is placed into service prior to the end of 2016, it should qualify for the 30% tax credit. Some people do not have enough tax liability to take the whole credit in

Yes, I agree with Kris. The tax credit is applied as a deduction to line 44 tax (on taxable income) but the self-employment tax is then added on line 56. But the same is true of all other deductions, exemptions, and credits too. And it doesn't change the fact that if someone has no taxable income
