Answer:
A. Cash ⇒ Neither
Cash is a current asset not a liability at all.
B. Federal income tax payable this year ⇒ Current liability.
If a liability is to be paid within the current period then it is a current liability and as federal income tax payable is a liability and it is due this year, it is a current liability.
C. Long-term note payable ⇒ Noncurrent liability
If the liability is for more than the current period then it is a non-current liability.
D. Current portion of a long-term note payable ⇒ Current liability
The current portion of a long term note payable is due to be paid within current period so is a current liability.
E. Note Payable due in four years ⇒ Noncurrent liability
This is due for more than the current period so is a non-current liability.
F. Interest Expense ⇒ Neither
This is not a liability but an expense that goes to the income statement.
G. State income tax ⇒ Neither
This is not a liability either but an expense that goes to the income statement.
