Entries to be passed in the journal even though subsidiary books are maintained:

In the process of accounting, subsidiary books are used to record specific transactions of similar nature. These books include the cash book, purchase book, sales book, purchase return book, sales return book, etc. However, there are certain entries that need to be passed in the journal, even if all the subsidiary books are maintained. Let's explore these entries in detail:

1. Opening Entries:
At the beginning of a financial year or when a new business is started, opening entries need to be recorded in the journal. These entries include the initial capital introduced by the owner, assets brought into the business, liabilities incurred, and other relevant transactions. Since these entries do not fall under any specific subsidiary book, they are directly recorded in the journal.

2. Closing Entries:
At the end of the financial year, closing entries are recorded in the journal to transfer the balances of revenue and expense accounts to the income summary account and ultimately to the capital account. These entries summarize the financial results of the business for the period and help in the preparation of financial statements.

3. Rectification Entries:
Sometimes, errors or mistakes are identified in the subsidiary books or other accounting records. To rectify these errors, journal entries are passed in the general journal. Rectification entries are made to correct errors related to amounts, accounts, or classifications. These entries help in maintaining accurate and reliable financial records.

4. Adjusting Entries:
Adjusting entries are necessary to bring the accounts to their proper and accurate balances before preparing the financial statements at the end of an accounting period. These entries are made for transactions that are not recorded in the subsidiary books, such as accruals, prepayments, depreciation, provisions, etc. Adjusting entries ensure that revenues and expenses are recognized in the correct accounting period.

5. Opening and Closing Entries of Subsidiary Books:
Although subsidiary books are used to record specific transactions, the opening and closing entries of these books are recorded in the general journal. The opening entries of subsidiary books are made to transfer the balances from the previous year, while the closing entries are passed to close the respective accounts and transfer the balances to the next year.

Conclusion:
While subsidiary books are efficient in recording transactions of similar nature, there are certain entries that need to be recorded in the journal. These entries include opening entries, closing entries, rectification entries, adjusting entries, and the opening and closing entries of subsidiary books. By maintaining a proper journal alongside the subsidiary books, businesses can ensure accurate and reliable financial records.
