The core principle of accrued expenses lies in the matching principle, a cornerstone of the accrual basis of accounting. This principle states that expenses should be recorded in the same accounting period as the revenues they help generate. Let's say your accounting period ends on December 31st. If your business uses utilities in December, but the utility bill won't arrive until January and isn't due until February, you still need to record the December utility cost in December.
Here’s how it typically works:
1. Identify Incurred Costs: At the end of an accounting period (month, quarter, year), you review for any services or goods your business received but hasn't paid for or received an invoice for yet.
2. Estimate the Amount: You might need to estimate the cost if the exact bill isn't available. For recurring expenses like salaries, rent, or interest, this is often straightforward.
3. Make an Adjusting Entry: An accounting entry is made to debit (increase) an expense account on the income statement and credit (increase) an "Accrued Expenses" (or a specific accrued liability like "Accrued Wages Payable") account on the balance sheet. This increases your reported expenses for the period and increases your liabilities.
4. Reverse/Pay Later: When the actual invoice arrives or the payment is made in the next period, the accrued expense liability is reduced (debited), and cash is credited for the payment. If an estimate was used, any difference is adjusted.
This systematic approach ensures your financial statements, especially the income statement and balance sheet, accurately reflect all financial obligations and the true cost of doing business during a specific period. For tax purposes, businesses using the accrual method generally expense items when they incur an economic performance for them, regardless of when cash is paid.
