Residential energy credit for solar panels, claimed last year and was given a portion of the 30%, this year filing for difference but still not receiving the balance, why?
Even if your solar energy credit got carried over into your 2017 income tax return, you still might not get the credit because for 2017:
Your income is at a level that's not taxed at all.
You're getting other tax credits that have reduced your tax owed to zero.
If your credit can be carried forward to next year (2018), we do that for you.
The Residential energy credit is a nonrefundable credit. A nonrefundable
credit is subtracted from your income tax liability, up
to the total amount you owe. But unlike a refundable tax credit,
a nonrefundable creditcannot reduce
your tax balance beyond zero.
