I hope it's ok to ask state-specific questions here ...
North Carolina has a credit called "credit for income tax paid to another state or country". I am using it to take a foreign tax credit (FTC) for foreign taxes withheld on an international ETF.
As with the federal FTC (when it exceeds a $300/600 threshold), the allowable credit is limited based on your North Carolina income, tax, and the amount of foreign income. What I can't figure out, is it possible to carry-over the unused credit to future years (as with the federal FTC)? Form D-400TC, Part 3, Line 14 is "Tax credits carried over from previous years", but nowhere can I find what credits CAN be carried over.
