Journal entries are used to record transactions in accounting and are made in the company’s general journal. They affect at least two accounts, and the total debits must equal the total credits. They are the foundation of accounting and bookkeeping since all data found in the general ledger and financial statements originate from the journals.
Tip:
With small business accounting software, business owners and bookkeepers rarely have to make journal entries, as good accounting software will make the entry for you after you complete a form. For instance, when you send a customer an invoice, it will record a journal entry to debit Accounts Receivable and credit Sales.
Parts of a Journal Entry
Understanding the parts of a journal entry is a bookkeeping basic that all bookkeepers should understand. The simplest form of a journal entry has one debit and credit entry. But to keep accounting records organized and traceable, a journal entry must also contain a date, posting reference, and description. In manual accounting, all journal entries go to the general journal, also known as the “book of original entry.”
Journal | Page 1 | ||||
---|---|---|---|---|---|
Date 2022 | Description | Post. Ref. | Debit | Credit | |
Aug. | 25 | Account to Debit Account to Credit Journal entry description | 1001 2002 | 10,000 | 10,000 |
- Date: This must be the date of the transaction, not when it was entered in the journal.
- Journal Entry Description: This line item briefly describes the purpose of the entry.
- Posting Reference (Post. Ref.): This shows the general ledger account numbers of the accounts debited or credited. The bookkeeper usually fills out this section when posting journal entries to their respective general ledger accounts. For example, you debited Cash for $10,000. In the chart of accounts, the account number of Cash is 1001. After posting the $10,000 debit to Cash in the general ledger, you should enter 1001 in the posting reference column corresponding to the debit entry.
- Debit and Credit Entries: These line items should state the affected accounts in the transaction. The credit entries are always indented to the right and all debit entries are listed prior to the credit entries.
Types of Journal Entries
Journal entries have different types—such as opening, adjusting, and reversing entries. If you have a manual accounting system, knowing these types is essential in daily bookkeeping; however, if you use a small business accounting software like QuickBooks Online, the types don’t matter in daily bookkeeping.
Accounting software makes the journal entries “behind the scenes” whenever you enter an invoice, bill, and payment. The only instances you’ll make journal entries in them are for end-of-year adjustments or under unusual circumstances.
These entries carry over the ending balances of permanent accounts from the previous accounting period to the current accounting period. The accountant should refer to the post-closing trial balance to make the opening entries. To illustrate, let’s prepare the opening entry of New Valley Marketing for the fiscal year beginning January 1, 2023.

Account | Debit | Credit |
Cash in bank - Wells Fargo Accounts Receivable Prepaid Rent Merchandise Inventory Equipment Accumulated Depreciation Accounts Payable Accrued Expenses Unearned Income Long-term Notes Payable Stacey Wilson, Capital TOTAL | $ 28,000 47,000 5,000 50,000 25,000 155,000 | $ 5,000 14,000 18,000 29,000 40,000 49,000 155,000 |
To make the opening entries, debit all accounts with normal debit balances and credit all accounts with normal credit balances. Our opening entries for fiscal year 2023 are:

Always foot the debit and credit columns to ensure the equality of debits and credits.
A transfer entry moves or allocates amounts from one account to another. Usually, they affect accounts within the same class. Let’s assume that Stacey Wilson, the owner of our fictitious business New Valley Marketing, created a payroll account on January 15, 2023, and transferred $10,000 from the cash account. The transfer entry is:
Journal | Page 1 | ||||
---|---|---|---|---|---|
Date 2023 | Description | Post. Ref. | Debit | Credit | |
Jan. | 15 | Cash - Payroll Cash in bank - Wells Fargo To transfer cash for payroll account | 10,000 | 10,000 |
A correcting entry corrects errors and mistakes discovered in the books. To illustrate, let’s assume that the bookkeeper of Stacey Wilson erroneously recorded the electric bill for the month of January as $151 instead of $115. The correcting entry is:
Journal | Page 1 | ||||
---|---|---|---|---|---|
Date 2023 | Description | Post. Ref. | Debit | Credit | |
Jan. | 15 | Cash in bank - Wells Fargo Utilities Expense To correct error in recording utility | 36 | 36 |
The error above is a transposition error. Since the original amount is only $115, we need to reduce Utilities Expense by $36 and increase the Cash account by the same amount.
The adjustment process is the result of applying the accrual basis of accounting. Since the accrual method records transactions at occurrence rather than when cash is paid or received, some adjustments are needed to update the balance of accounts. There are three kinds of adjusting entries: accrual, deferral, and depreciation adjustments.
An adjusting entry always affects at least one income statement account (nominal accounts) and one balance sheet account (real accounts).
Accruals
An accrual is an item of income or expense that’s recognized even if cash isn’t yet received or paid. Particularly, the two types of accruals are accrued expenses and accrued revenues. To illustrate, let’s consider the following transactions:
- Accrued expenses: New Valley Marketing recorded 100 hours accrued paid time off (PTO) of employees for February 2023. The hourly rate is $25. During February, the employees took 40 hours of PTO. The 60 hours of PTO accrued but not taken ($1,500) must be accrued at the end of February.
- Accrued revenues: The company accepted a 6% $5,000 60-day note receivable from a customer for consulting fees. The interest accrued at the end of February was $50.
The entries to record the accruals and their subsequent adjustments are:
Journal | Page 2 | ||||
---|---|---|---|---|---|
Date 2023 | Description | Post. Ref. | Debit | Credit | |
Feb | 1 | Notes receivable Consulting fees earned To record note received | 5,000 | 5,000 | |
27 | Interest receivable Interest income To record accrued interest | 50 | 50 | ||
28 | Salaries & wages expense Salaries & wages payable To accrue unused PTO for Feb. | 1,500 | 1,500 |
Explanations:
- The goal of accruing expenses is to recognize it in the proper accounting period when it was incurred. In the example above, the 60 hours PTO accrual in February appropriately records the expense in February. The accrual reports the expense in February because it belongs to the employees’ entitlement in February even though they aren’t yet used.
- Just like accrued expenses, we also accrue revenues to recognize them in the period when it was earned. The three-month consultancy contract of Stacey Wilson is an example of an accrued revenue. As of February 1, the company already earned $12,000 even if the customer hasn’t paid. The consultancy contract on February 1 is a revenue of February, regardless of the fact that the customer will pay $4,000 every month.
Deferrals
A deferral is an item of income or expense where cash has been received or paid but not yet earned or incurred. Deferrals are otherwise referred to as prepayments. The types of deferrals are deferred expenses or prepaid expenses and deferred revenues. Let’s illustrate the two using the following transactions:
- Deferred revenues: On January 15, a customer paid $2,000 in advance to hire Stacey Wilson for a consulting engagement on February 26.
- Prepaid expenses: Stacey Wilson purchased a 12-month fire insurance for the building on January 31, 2023. The annual premium is $12,000. The first month expired on February 28.
The entries to record the deferrals and their subsequent adjustments are:
Journal | Page 4 | ||||
---|---|---|---|---|---|
Date 2023 | Description | Post. Ref. | Debit | Credit | |
Jan. | 15 | Cash Unearned consulting fees To record customer prepayment | 2,000 | 2,000 | |
31 | Prepaid insurance Cash To record fire insurance policy | 12,000 | 12,000 | ||
Feb. | 26 | Unearned consulting fees Consulting fees earned To adjust earned consulting fees | 1,000 | 1,000 | |
28 | Insurance expense Prepaid insurance To adjust for expired insurance | 1,000 | 1,000 |
Explanations:
- Under revenue recognition principles, revenue should be recognized only if the company has provided the goods or services agreed upon.
- On January 15, Stacey hasn’t provided the consulting engagement, so we shouldn’t recognize revenue as of that date even though cash was already paid. We temporarily park the amount in a liability account called Unearned Consulting Fees because Stacey still has the liability to perform the consulting engagement.
- On February 26, Stacey completed the consulting engagement, so we should recognize the revenue by crediting Consulting Fees Earned, a revenue account.
- A prepaid expense is an expense paid in advance. In the example above, Stacey purchased a 12-month fire insurance. Since the policy covers 12 months, we shouldn’t recognize the whole $12,000 as an expense because the insurance hasn’t yet expired. As the months go by, a portion of the insurance expires—and the expired portion must be recorded as an expense. Hence, we debit insurance expense for the expired amount.
Depreciation
The last (and the easiest) adjusting entry is depreciation. It simply records the periodic depreciation as expense and updates the accumulated depreciation account on the balance sheet. Depreciation adjustments usually are done at year-end. The entry to adjust depreciation records is:

Closing entries are entries that close nominal or income statement accounts. Take note that income statement accounts always start the new accounting period with a zero balance. All income and expenses of previous periods are closed to the capital or retained earnings account of the business.
To illustrate, let’s use the adjusted trial balance of New Valley Marketing as of December 31, 2023. The items highlighted in yellow are the income statement accounts that we need to close.

General & Administrative Expense | 21,000 | |
Miscellaneous Expense | 3,000 | |
Interest Expense | 2,000 | |
TOTAL | 483,500 | 483,500 |
In closing, we use a special account called Income Summary. It’s a temporary account where we close all income and expenses and then transfer its balance to the capital accounts.
First, let’s close all expense accounts. Since the normal balance of expense accounts is debit, let’s credit them to zero them out.

Let’s do the same thing for revenues. Credits increase revenue so let’s debit them to zero them out.

Dec. | 31 | Consulting fees earned Sales Income summary To close revenue accounts | 300,000 25,000 | 325,000 |
The balance of the income summary account is $84,000 credit ($325,000 – $241,000). If the income summary account is on a credit balance, it means that the company earned a net income during the year. Otherwise, a debit balance means that it incurred a net loss.
Tip:
After closing all income and expense accounts, the income summary account should match your net income or loss on your Statement of Profit and Loss.
And finally, let’s close the income summary account to the capital account by debiting it to zero it out.

A reversing entry makes it easy and convenient to record future transactions and is made at the beginning of the next accounting period. It’s an optional step in the accounting cycle but can facilitate future accounting transactions without making additional journal entries. When making reversing entries, you just have to reverse the adjusting entry you made.
To illustrate, let’s assume that Stacey Wilson obtained a $20,000 bank loan with a total interest expense of $2,400 on May 1, 2023. The loan must be paid on April 30, 2024. The accountant accrued the $1,600 interest on December 31, 2023.
The initial and adjusting entries to record the loan are:
Journal | Page x | ||||
---|---|---|---|---|---|
Date 2023 | Description | Post. Ref. | Debit | Credit | |
May | 1 | Cash Loan payable To record bank loan | 20,000 | 20,000 | |
Dec. | 31 | Interest expense Interest payable To accrue interest on bank loan | 1,600 | 1,600 |
The reversing entry and the entry to record the payment of the loan are:
Journal | Page x | ||||
---|---|---|---|---|---|
Date 2023 | Description | Post. Ref. | Debit | Credit | |
Jan. | 1 | Interest payable Interest expense To reverse adjusting entry | 1,600 | 1,600 | |
Apr. | 30 | Loan payable Interest expense Cash To record payment of loan | 20,000 2,400 | 22,400 |
If there’s no reversing entry, our entry on April 30, 2024, will be different:
Journal | Page x | ||||
---|---|---|---|---|---|
Date 2023 | Description | Post. Ref. | Debit | Credit | |
Apr. | 30 | Loan payable Interest expense Interest payable Cash To record payment of loan | 20,000 800 1,600 | 22,400 |
Without the reversing entry, we still have to debit $800 interest expense for interest incurred from January 1 to April 30, 2024, and debit $1,600 to interest payable to record payment of accrued interest in the previous year.
But with reversing entries, it would be easier to record the payment of the loan since we can directly debit the total interest of $2,400 in interest expense. To better show you how the reversing entries occurred, let’s use the T-Account.
Interest Expense | |||
---|---|---|---|
Ending balance 12/31/23 | 0 | ||
Payment of loan 04/30/24 | 2,400 | 1,600 | Reversing entry 01/01/24 |
Ending balance 12/31/24 | 800 |
Notice that the balance of interest expense above is $800, which is the same amount of interest expense we debited if we didn’t make a reversing entry.
Writing & Balancing Journal Entries
You can write journal entries in a single or compound entry. A single entry only has one debit entry and one credit entry, whereas a compound entry has more than one debit entries or credit entries. Regardless of how many debit or credit entries you make, the total debits and credits must be equal. The key to balancing these two is knowing how a debit and credit affect an account.
The chart below shows the effect of debits and credits on the five major account classifications:
Take note that balancing debits and credits don’t provide assurance that everything is correct. Balancing the two only means that you applied the debit-credit rules correctly but doesn’t immediately mean that you accounted for transactions correctly.
Bottom Line
Accounting journal entries are the foundations of double-entry bookkeeping. Mastering the art of journalizing is the responsibility of a bookkeeper, but as a small business owner, you must also take steps to understand how they work. While small business accounting software does away with day-to-day journal entries, bookkeepers and business owners must know how to make adjusting and reversing journal entries at the end of the period to properly account for accruals.
