When an expense is incurred but has not been paid it should be credited where?

When an expense is incurred but not yet paid, it should be credited to an "Accounts Payable" or "Accrued Expenses" account, reflecting the obligation to pay in the future. The corresponding debit should be recorded in the relevant expense account, such as "Rent Expense" or "Utilities Expense." This ensures that the financial statements accurately represent the company's liabilities and expenses in the period they were incurred.
