What exactly is a closing entry?
A closing entry is an accounting entry made at the end of a company’s financial year to bring the profit and loss account to zero and carry its balance forward to the balance sheet. In other words, it allows you to ‘close’ the books and prepare the accounts for the new financial year.
This step is essential because:
- It reveals the company’s profit or loss for the financial year.
- It ensures that the financial statements reflect the company’s true financial position.
- It leaves the accounts ready for the next period.
In short, the closing entry is the way to draw a line under one year’s accounts so that another can begin with complete clarity.
Which accounts are closed at the end of the financial year?
In the closing entry, all income and expense accounts are closed, that is, those that form part of the profit and loss account. These are the accounts that determine the profit or loss for the financial year.
For example:
- Revenue from sales (700).
- Staff costs (640).
- Other operating expenses (62X).
Once closed, their balances are transferred to the profit and loss account (129). The closing balance of this account will show whether the company made a profit or a loss during the financial year.
How are the closing entries made?
The process is usually divided into three stages:
- Adjustment entry
Before closing the accounts, an adjustment entry is made. This involves transferring the balances of the income and expense accounts to the profit and loss account. - Closing entry
After the adjusting entry, the balances of all balance sheet accounts (assets, liabilities and equity) are recorded, so that the books show a zero balance. - Closing and opening entries
Once the financial year has been closed, at the start of the new one the opening entry is made, which is the reverse of the closing entry. In this way, the accounts once again reflect the company’s financial position for the new financial year.
The importance of everything balancing
The closing entry must balance mathematically. This is not merely a recommendation, but a fundamental accounting requirement. If your entries do not balance, it means that:
- There is an error in the recording of transactions
- There are accounts that have not been properly settled
- The calculations contain arithmetic errors
To check that everything is correct, the sum of the ‘Debit’ amounts must be exactly equal to the sum of the ‘Credit’ amounts.
Example of a closing entry
Imagine a company which, during the year, recorded:
- Sales revenue: €50,000
- Staff costs: €20,000
- Miscellaneous expenses: €5,000
The adjusting entry would be:
- Debit: 50,000 (Sales revenue, account 700)
- Credit: 20,000 (Staff costs, 640)
- Credit: 5,000 (Other expenses, 62X)
- Credit: 25,000 (Profit for the financial year, account 129)
Next, in the closing entry, all balance sheet accounts are balanced, including banks, suppliers, customers and equity.
This simple example shows how the process enables us to determine the final profit of €25,000 and leave the books ready for the new financial year.
Differences between the accounting year-end and the tax year-end
A frequently asked question is what the difference is between the accounting year-end and the tax year-end. Although both take place at the end of the financial year, they have different objectives:
Accounting year-end:
- Objective: To determine the profit or loss in accordance with accounting standards
- Regulatory framework: General Accounting Plan
- Recipients: Shareholders, investors, financial institutions
Tax year-end:
- Objective: To calculate the tax base
- Regulatory basis: Corporation Tax Act
- Intended audience: Tax authorities
The accounting profit often differs from the taxable profit due to temporary and permanent differences set out in tax legislation.
Practical tips for success
To ensure your year-end entries are always correct, we recommend:
- Check systematically: Before closing the accounts, verify that all transactions for the financial year have been recorded
- Use accounting software: Digital tools minimise errors and streamline the process
- Document everything: Keep supporting documentation for each entry for future audits
- Practise regularly: Experience is essential in accountancy
