Journal Entry Types

Why This Matters

Journal entries are the foundation of the entire accounting cycle. Every financial statement you'll analyze on an exam traces back to these original records. You're being tested on your ability to recognize when different entry types are required, why they exist, and how they maintain the integrity of financial reporting under accrual accounting. Understanding the purpose behind each entry type connects directly to larger concepts like the matching principle, revenue recognition, and the distinction between temporary and permanent accounts.

Don't just memorize that adjusting entries happen at period-end. Know why they're necessary (accrual basis requires matching revenues and expenses to the correct period) and how they differ from closing entries (which reset temporary accounts rather than update balances). On exam questions about the accounting cycle, your ability to distinguish entry types by their function rather than just their timing will set you apart.

Recording Day-to-Day Transactions

These entry types capture financial activity as it happens, forming the raw data that flows through the entire accounting system. The goal is complete, chronological documentation of every transaction affecting the accounting equation.

General Journal Entries

The general journal is the chronological record of all transactions and serves as the primary source document for the entire accounting system.

Every journal entry requires the same components: date, accounts debited and credited, dollar amounts, and a brief explanation (sometimes called the "narration"). The core rule is simple: debits must equal credits in every entry, which keeps the fundamental accounting equation in balance:

$Assets = Liabilities + Equity$

For example, if a company purchases supplies for $\$500$ cash, you'd debit Supplies (asset increases) and credit Cash (asset decreases) for $\$500$ each.

Compound Entries

A compound entry involves more than two accounts in a single journal entry. You'll see multiple debits, multiple credits, or both recorded together.

Common scenarios include:

• A sale where you record revenue and sales tax payable in one entry
• Payroll entries with multiple withholdings (federal tax, state tax, insurance)
• Asset purchases involving a trade-in and partial cash payment

Compound entries streamline complex transactions while still requiring total debits to equal total credits.

Recurring Entries

These cover repetitive transactions recorded at consistent intervals: monthly rent, weekly payroll, quarterly insurance premiums. In practice, accounting software automates these to reduce errors and ensure timely recognition. Recurring entries also support the consistency principle by treating similar transactions identically across periods.

Period-End Adjustments

Adjusting entries exist because of accrual accounting: revenues and expenses must be recognized when earned or incurred, not when cash changes hands. These entries bridge the gap between cash-basis reality and accrual-basis reporting.

Adjusting Entries

There are four main categories, and sorting them out is one of the trickiest parts of this topic:

• Accrued revenues: Revenue you've earned but haven't received cash for yet (e.g., interest earned but not yet collected). Debit a receivable, credit revenue.
• Accrued expenses: Expenses you've incurred but haven't paid yet (e.g., salaries owed to employees at month-end). Debit an expense, credit a payable.
• Deferred revenues (unearned): Cash received before you've earned the revenue (e.g., a customer pays for six months of service upfront). As you earn it, debit the liability, credit revenue.
• Deferred expenses (prepaid): Cash paid before you've used the benefit (e.g., prepaid insurance). As time passes, debit an expense, credit the prepaid asset.

Two rules to remember: adjusting entries are always made at period-end before preparing financial statements, and they never involve the Cash account. If cash is changing hands, it's not an adjusting entry.

Reversing Entries

These are optional entries made on the first day of the new period to undo specific adjusting entries. Their purpose is purely practical: they simplify the bookkeeping when cash related to an accrual will be received or paid shortly after period-end.

For example, if you accrued $\$2{,}000$ in salaries at December 31, a reversing entry on January 1 lets you record the full paycheck normally in January without having to split the entry between what was accrued and what wasn't. Reversing entries are best used for accruals (accrued expenses and accrued revenues), not for deferrals or depreciation.

Closing the Books

Closing entries serve a specific structural purpose: separating one accounting period's performance from the next. Temporary accounts measure activity for a single period and must be reset to zero; permanent accounts carry forward indefinitely.

Closing Entries

Temporary accounts (revenues, expenses, and dividends/withdrawals) get closed, meaning their balances are transferred to Retained Earnings (or Owner's Capital in a sole proprietorship). Permanent accounts (assets, liabilities, and equity) remain open and carry their balances into the next period.

The four-step closing process:

1. Close revenues to Income Summary: Debit each revenue account for its balance, credit Income Summary for the total.
2. Close expenses to Income Summary: Credit each expense account for its balance, debit Income Summary for the total.
3. Close Income Summary to Retained Earnings: If revenues exceeded expenses, Income Summary has a credit balance (net income), so you debit Income Summary and credit Retained Earnings. Reverse this if there's a net loss.
4. Close Dividends to Retained Earnings: Debit Retained Earnings, credit Dividends.

After these four steps, every temporary account has a zero balance and is ready for the next period.

Opening Entries

Opening entries establish beginning balances when starting a new accounting system or transitioning between systems. They record assets, liabilities, and equity at their values as of the transition date. This is most relevant during system migrations, such as moving from manual bookkeeping to accounting software or switching platforms.

Error Correction and Maintenance

Even careful accountants make mistakes. Correcting entries maintain the integrity of financial records while creating a clear audit trail. The key principle: never erase or delete. Always document corrections transparently.

Correcting Entries

Correcting entries rectify errors in previously recorded entries, whether that's a wrong amount, a wrong account, or an omitted transaction entirely. Each correcting entry must include documentation explaining the original error and the correction being made.

Timing matters here:

• Errors found in the same period are corrected directly with a journal entry.
• Errors discovered in a later period may require a prior period adjustment, which affects Retained Earnings and is disclosed in the financial statements.

Self-Check Questions

1. Which two entry types are specifically designed to handle the transition between accounting periods, and how do their purposes differ?

2. A company recorded three months of prepaid insurance at the start of the quarter. What type of entry is needed at month-end, and which account category (accrued or deferred) does this represent?

3. Compare and contrast adjusting entries and correcting entries: What triggers each type, and how do their effects on financial statements differ?

4. If an FRQ asks you to "prepare the entries necessary to close the books," which accounts would you expect to see debited and credited, and what is the ultimate destination of these balances?

5. Why might a company choose to use reversing entries for accrued salaries but not for depreciation adjustments? What characteristic of the underlying transaction makes reversing entries useful?
