When an expense is incurred but has not been paid it should be credited to which account?

When an expense is incurred but not yet paid, it should be credited to an expense account and debited to a liability account, typically called "Accounts Payable" or "Accrued Expenses." This reflects that the company has incurred an obligation to pay for the expense in the future. The expense is recognized in the period it was incurred, while the liability indicates the amount owed.
