Closing Entries

Closing entries are the journal entries you make at the end of an accounting period to zero out your temporary accounts (revenue, expenses, and owner draws or dividends) and move their net balance into a permanent equity account, usually retained earnings.

In plain terms, closing entries reset your income and expense accounts to zero so the next period starts with a clean slate, while the profit or loss you earned stays on the books inside equity.

In 15 years handling more than 1,900 close-and-cleanup projects for small businesses across the US, I have learned that the close is where a set of books either earns trust or loses it.

That reset is what makes each period stand on its own. If you never closed the books, January's sales would still be sitting in the revenue account in December, and you would have no honest way to say how a single month, quarter, or year actually performed.

Understanding closing entries is one of the building blocks of accurate reporting, and it connects directly to the wider picture covered in our Financial Statements guide.

If the month-end routine sounds like more than you want to own, letting our team handle your books through professional monthly bookkeeping keeps the close accurate without pulling you away from running the business.

In this article I will walk through what closing entries are, the four standard entries, a worked example with real dollar figures, and the mistakes I see most often after 15 years and more than 1,900 projects closing and cleaning up small-business books.

What Closing Entries Are

Every account in your books is either temporary or permanent, and closing entries exist to deal with the temporary ones.

Temporary vs. permanent accounts

Temporary accounts track activity for a single period. Revenue, cost of goods sold, operating expenses, and owner draws or dividends all reset to zero at the end of the period. They are sometimes called nominal accounts.

Permanent accounts, also called real accounts, include cash, accounts receivable, equipment, loans, accounts payable, and equity. Their balances roll forward continuously because they describe what the business owns and owes at a point in time, not what happened during a window of time.

Closing entries touch only the temporary accounts. The whole point is to empty them so the next period measures its own performance, not a running total stretching back to the day you opened.

Why the reset matters

Without a period-end reset, your income statement becomes meaningless. Revenue would accumulate month after month, and you could never answer a simple question like "Did we make money in Q2?" The reset also protects the integrity of retained earnings, the account that holds cumulative profit the business has kept rather than distributed.

According to Investopedia's explanation of closing entries, this transfer is what keeps the income statement and the balance sheet in sync at the end of each cycle.

The Four Closing Entries

The traditional close uses an intermediate holding account called Income Summary. You move revenue and expenses into it, net them, then push the result to retained earnings. Here are the four entries in order.

Close revenue to Income Summary

Revenue accounts carry credit balances, so to zero them you debit each revenue account and credit Income Summary for the total. If you booked $42,000 in sales for the month, you debit Revenue $42,000 and credit Income Summary $42,000. Revenue is now zero and ready for next period.

Close expenses to Income Summary

Expense accounts carry debit balances, so you do the reverse: credit each expense account and debit Income Summary for the total. Every expense line, rent, payroll, software, merchant fees, gets flushed out here. After this entry, Income Summary holds the period's net income or net loss.

Close Income Summary to retained earnings

Now you empty Income Summary itself. If the business earned a profit, you debit Income Summary and credit Retained Earnings. If it took a loss, you flip the entry. This is the moment the period's result becomes part of permanent equity.

The Financial Accounting Standards Board, which sets US GAAP, treats retained earnings as the cumulative record of net income kept in the business over its life.

Close dividends or owner draws

Dividends (for corporations) and owner draws (for sole proprietors and partnerships) are not expenses, so they never touch Income Summary. You close them directly against Retained Earnings or the owner's capital account: credit Dividends or Draws, debit Retained Earnings. This reduces equity by what the owners pulled out during the period.

A Worked Example

Say a small e-commerce shop finishes June with the figures below. Here is how the numbers flow through the close.

Total expenses come to $30,500, so net income for June is $11,500 ($42,000 minus $30,500). That $11,500 moves into retained earnings, then the $4,000 in owner draws comes back out, leaving retained earnings at $37,500 ($30,000 plus $11,500 minus $4,000). Every temporary account is now zero, and equity reflects the month cleanly.

Notice that the net income figure here is exactly what would appear on the Profit and Loss Statement for June. Closing entries are the mechanism that carries that bottom line off the income statement and onto the balance sheet.

How Closing Entries Fit the Monthly Close

Closing entries are the last step of the period-end routine, not the whole thing. Before you close, you reconcile bank and credit card accounts, record accruals, and post depreciation.

Once those are done and every transaction lives in the right place in your General Ledger, the closing entries lock the period.

After the close, the ripple effects show up across every core report. The net income you moved to retained earnings is the same number that reconciles your Balance Sheet, because assets must equal liabilities plus equity, and retained earnings is part of equity.

That change in retained earnings is also the headline line on your Statement of Equity, which explains how owner value moved during the period.

Even the Cash Flow Statement starts from net income when you build it with the indirect method, so a sloppy close distorts all four statements at once.

Manual Entries vs. Software Closing

If you learned accounting from a textbook, you learned the manual four-entry method with Income Summary. In practice, almost no small business posts those entries by hand anymore.

Platforms like QuickBooks Online and Xero handle the close automatically.

Per Intuit's QuickBooks guidance, the software rolls net income into retained earnings at year-end without you touching a journal entry, and it can lock prior periods with a closing date and password so nothing gets changed after the fact.

The Income Summary account often does not even appear because the system nets revenue and expenses internally.

That convenience does not make the concept optional. You still need to understand what is happening, because software only closes correctly if the underlying data is right. Here is how the two approaches compare in a typical small-business setting.

The lesson from both columns is the same: the entry is easy, but the timing is everything. Closing before your accounts are reconciled just locks in bad numbers faster.

Common Mistakes to Avoid

A few errors show up again and again when I clean up other people's closes.

Closing before reconciling

The single most damaging mistake is running the close while bank and credit card accounts are still unreconciled. You end up moving unverified numbers into permanent equity, and unwinding that later is far more work than doing it in order the first time. Reconcile first, close last.

Treating draws or dividends as expenses

As covered above, owner draws and dividends reduce equity directly. Routing them through the income statement overstates expenses, understates profit, and misstates the tax basis of the business.

Closing the wrong period

Posting a closing entry with the wrong date, or reopening a locked period and re-closing it, quietly corrupts your year-to-date figures.

The IRS expects consistent accounting periods, a point it spells out in Publication 538 on accounting periods and methods. Set a closing date lock and respect it.

Forgetting the close entirely

With cash-basis, spreadsheet-run books, some owners never close at all. Revenue simply piles up year over year. Across the BooksCure network, roughly 40 percent of the cleanup engagements we onboard involve books that were never formally closed even once, so catching it is one of the first things a cleanup engagement looks for.

Case Study: A Charlotte E-Commerce Owner Who Never Closed

Devin, who runs a growing e-commerce shop in Charlotte, North Carolina, came to us convinced his business had a cash problem. His accounting software showed almost $310,000 in "revenue," and he could not understand why his bank balance did not reflect anything close to that kind of success.

The issue was that his books had never been closed since he started three years earlier. Revenue and expenses from all three years were stacked in the same temporary accounts, so his income statement was showing three years of activity as if it were one blockbuster period, while retained earnings sat untouched.

Once we reconciled each year, posted the missing accruals, and ran proper closing entries for each period, his true trailing-twelve-month revenue was closer to $118,000 with about $19,000 in retained earnings.

The correction took roughly nine hours of cleanup work. More importantly, it gave Devin numbers he could actually plan and file taxes from, and it kept him from applying for a line of credit against revenue that was never real. That kind of clarity is the whole reason the close exists.

Conclusion

Closing entries are the quiet discipline that keeps your financial reports honest. By zeroing out revenue, expenses, and draws at the end of each period and parking the net result in retained earnings, you give every month, quarter, and year a clean starting line and a truthful ending.

The mechanics are simple, four entries, or one automated step in modern software, but the timing and accuracy behind them are what separate books you can plan from books that quietly mislead you.

If you take one thing from this guide, let it be the order of operations: reconcile, adjust, then close, never the other way around. Whether you post the entries yourself or lean on software (or hand the whole routine to a bookkeeper), respecting that sequence is what turns raw transactions into financial statements you can stand behind.
