Year-End Closing Entries: How to Close the Books and Open the Next Year

Year-end closing entries move the balances of every revenue and expense account into retained earnings, so the new fiscal year starts with zero profit and loss while assets, liabilities and equity carry forward. The classic route runs through an income summary account: revenues and expenses close into it, and its net balance (the profit or loss for the year) closes into retained earnings.

This guide walks through the checklist to finish before you close, the mechanics of closing entries with full numeric examples for a profit and a loss, the opening entry that starts the next year, reopening a closed year, lock dates, and how Ledgeriano automates the whole sequence.

#What are year-end closing entries?

Closing entries are journal entries recorded on the last day of the fiscal year that bring every temporary account (revenue, expense and, where used, the income summary) to a zero balance and transfer the net result to retained earnings. Permanent accounts, meaning everything on the balance sheet, are not closed; their balances continue into next year.

Why bother? Because the income statement measures one period at a time. If 2026 sales were not closed, the 2027 sales account would start with last year's total already in it. Closing also makes the balance sheet complete: until profit is moved into retained earnings, equity is understated by exactly the year's profit.

#Checklist before you close the books

Closing is only as good as the balances you close, so finish the adjustments first. Work through this list in order; each item changes numbers that the later items depend on.

1. Post or delete every draft. Unposted entries do not count in reports, and Ledgeriano refuses to close a year that still has drafts.
2. Reconcile bank and cash accounts to statements and count the cash box.
3. Review receivables and payables by party. Chase or write off doubtful balances and confirm large supplier balances.
4. Count inventory and post the cost of goods sold adjustment so closing stock on the ledger matches the count.
5. Record depreciation and amortisation for the full year or the final month.
6. Book accruals and prepayments: unpaid utilities, salaries earned but unpaid, rent paid in advance, revenue billed in advance.
7. Revalue foreign currency balances at the closing rate (see the multi-currency accounting guide).
8. Estimate and record income tax expense and the related liability.
9. Review the trial balance at account level: look for negative cash, credit balances on expense accounts and suspense items.
10. Set a lock date at the year-end date so nobody posts into the period while you review statements.

Close only when the statements are final. Closing is reversible in Ledgeriano, but every reopen and re-close regenerates the next year's opening entry, and anyone who has already exported opening balances will need fresh figures.

#How closing entries work, step by step

Closing through an income summary takes three steps, and a net profit always ends up as a credit to retained earnings while a net loss ends up as a debit.

1. Close revenue accounts. Debit each revenue account for its credit balance; credit the income summary for the total.
2. Close expense accounts. Credit each expense account for its debit balance; debit the income summary for the total.
3. Close the income summary. If it has a credit balance (profit), debit it and credit retained earnings. If it has a debit balance (loss), credit it and debit retained earnings.

Many textbooks show these as three separate entries. Software usually combines them into a single closing voucher dated the last day of the year, which is easier to audit because one document explains the whole transfer.

#Worked example: closing a profitable year

Northwind Trading uses the IFRS chart of accounts and a calendar fiscal year. After all adjustments, the profit and loss accounts on 31 December 2026 show:

Revenue of 120,500 minus expenses of 112,500 gives a profit of 8,000.

#The closing entry

After posting, every revenue and expense account shows zero, the income summary shows zero (8,000 in, 8,000 out), and retained earnings has grown by 8,000. If retained earnings stood at 5,000 before, it is now 13,000.

#Worked example: closing a year with a loss

The same mechanics handle a loss; only the direction of the last two lines changes. Suppose a smaller subsidiary had sales of 60,000, cost of goods sold of 40,000, salaries of 18,000 and rent of 7,000. Expenses of 65,000 exceed revenue by 5,000.

The debit to retained earnings reduces equity by the 5,000 loss. If that pushes retained earnings into a debit balance, the balance sheet shows accumulated losses.

#What about dividends and owner drawings?

Dividends declared and owner drawings are equity accounts, not expenses, so they never pass through the income summary. Under IFRS most companies simply leave dividends in a contra equity account (3203 Dividends declared in the IFRS template) and transfer them to retained earnings with a normal journal entry once the year's accounts are approved. Sole traders often close drawings against the owner's capital account the same way.

#The opening entry for next year

The opening entry records every balance sheet balance on the first day of the new fiscal year, so the new year's trial balance starts exactly where the old balance sheet ended. It contains no revenue or expense lines, because those were closed.

Continuing the Northwind example, the balance sheet at 31 December 2026 becomes this opening entry dated 1 January 2027:

Two details matter here. First, receivables and payables are carried forward per party, so the new year's customer statements show Delta Stores owing 11,000 from day one, not an anonymous 18,000. Second, the opening entry uses the same account codes as the prior year; this is why keeping the chart of accounts stable across years matters.

#Lock dates, reopening and corrections

A lock date blocks creating, editing or posting entries dated on or before a chosen date, while a closed year blocks all postings. Use a lock date during the review period and closing once the statements are signed off.

In Ledgeriano:

• Lock date: set on the fiscal year. Any entry dated on or before it is rejected with a "period locked" error, including entries arriving through the API. Move the date forward month by month as you finish monthly closes.
• Closed year: accepts no entries at all. Reports remain available, so you can still print the final statements.
• Reopening: removes the closing entry and the next year's opening entry and sets the year back to open. You cannot reopen a year if the following year is already closed; reopen the later year first.
• Re-closing: closing again recreates the closing entry and regenerates the next year's opening entry from the corrected balances.

If you find an error after the next year has been running for months, there is an alternative to reopening: record a correcting entry in the current year against retained earnings (for a material prior-period error IAS 8 requires restating comparatives, and the correction is disclosed). Your auditor will usually prefer one approach; agree it before you touch a closed year.

#How Ledgeriano automates year-end closing

Ledgeriano turns the whole sequence into one action. When you close a fiscal year, it:

1. Checks that the year is open and has no draft entries.
2. Sums every posted revenue and expense account in base currency and builds a single posted closing entry, dated the last day of the year, that zeroes those accounts through the income summary (3302 in the IFRS template) and transfers the net result to retained earnings (3201, or another postable account you pick).
3. Marks the year as closed and records who closed it and when.
4. Creates the next fiscal year if it does not exist yet, copying the chart of accounts.
5. Generates a posted opening entry on the first day of the next year with every non-zero balance sheet balance, split by account and party. If an account code no longer exists in the new chart, that balance goes to the opening balance account (3301) so the entry still balances.

Closing and opening entries are system entries with their own voucher types (closing and opening), and they cannot be reversed like normal entries; reopening the year is the way to undo them. After closing, the financial statements show retained earnings updated, and the statement of changes in equity shows the transfer as "profit allocation". The features page lists the other fiscal-year tools, and closing a year is a credit-priced action like the others on the pricing page.

For groups with several companies, each business closes independently with its own calendar, currency and chart; see the multi-entity accounting overview. Companies on the Iranian calendar close on 29 or 30 Esfand, and the new year opens on 1 Farvardin.

#Closing under IFRS, US GAAP and for sole traders

The mechanics of closing are the same under every framework; what differs is the equity account that receives the result and how you present it. Neither IFRS nor US GAAP prescribes closing entries at all, because they are bookkeeping, not reporting. The standards only require that retained earnings on the balance sheet include all profits and losses to date.

If you run monthly closes, you do not post closing entries every month. A monthly close means reconciling, adjusting and moving the lock date forward; the income statement already reports any period you choose. The year-end close is the only one that resets profit and loss accounts.

#Common year-end closing mistakes

1. Closing before adjustments. Depreciation posted after closing lands in the next year.
2. Closing balance sheet accounts manually. Only temporary accounts close; zeroing the bank account in the old year and reopening it by hand invites mismatches.
3. Forgetting party detail. An opening entry with one lump sum for receivables loses every customer balance.
4. Leaving the income summary with a balance. It should always be zero after closing.
5. No lock date during review. Late entries change statements that have already been sent to the auditor.
6. Renumbering accounts after closing. Balances for missing codes fall into the opening balance account and need reclassifying.
