Ever stared at a journal entry that just won't balance, and you know it's because something at the end of the period is off? But that something is almost always a closing entry. And in ACC 201, Milestone 2 is where closing entries stop being a textbook definition and start being something you actually have to do Worth keeping that in mind..
Here's the thing — most students don't struggle because closing entries are hard. They struggle because nobody walks them through the reasoning behind each line. So let's fix that. This is the guide I wish I'd had when I sat down with my own ACC 201 worksheet at midnight, coffee going cold, wondering why retained earnings was acting so weird.
What Are Closing Entries (In Plain English)
Closing entries are the journal entries you make at the end of an accounting period — usually a month, quarter, or year — that reset your temporary accounts back to zero. Think of them as the "fresh start" entries.
The temporary accounts are the ones that track what happened during a specific period: revenues, expenses, and dividends (or withdrawals, depending on your setup). These get closed. The permanent accounts — assets, liabilities, and equity — carry forward into the next period untouched That alone is useful..
So why do we do this? Because accounting periods are like seasons. Worth adding: you track performance within the season, then you tally the results, and then you start fresh. Without closing entries, every revenue and expense you ever recorded would pile up in one account forever, and you'd never be able to tell what happened this year versus five years ago.
Why Milestone 2 Closing Entries Feel So Confusing
ACC 201 milestones are designed to build on each other. By Milestone 2, you've already journalized transactions, posted to the ledger, and probably prepared an adjusted trial balance. Now you're being asked to take that adjusted trial balance — which has your revenues, expenses, and updated balances — and turn it into a clean slate.
It sounds simple, but the gap is usually here.
The confusion usually comes from one of three places:
- Which accounts get closed. Students sometimes try to close assets or liabilities, which is wrong.
- The order of the entries. There's a specific sequence, and skipping a step makes the whole thing fall apart.
- Where the numbers go. Debit or credit? It flips depending on the account type, and getting it backward is the #1 mistake.
Once you understand why the order matters, the entries themselves start to feel almost obvious And it works..
The Four Closing Entries (And the Order That Makes Them Work)
Here's the core of Milestone 2. On top of that, there are four closing entries, and they happen in a specific sequence. Don't try to do them out of order — the numbers depend on each other.
1. Close Revenue Accounts to Income Summary
You take every revenue account on your adjusted trial balance, and you close them. Revenues normally have credit balances, so to bring them to zero, you debit each revenue account and credit Income Summary for the total Took long enough..
Let's say your company has Service Revenue of $20,000 and Sales Revenue of $5,000. Your entry would be:
- Debit Service Revenue $20,000
- Debit Sales Revenue $5,000
- Credit Income Summary $25,000
Income Summary is a temporary account that only exists during the closing process. It's like a holding pen.
2. Close Expense Accounts to Income Summary
Expenses normally have debit balances, so you do the opposite — credit each expense account and debit Income Summary for the total.
If you have Rent Expense $3,000, Wages Expense $10,000, and Supplies Expense $2,000:
- Debit Income Summary $15,000
- Credit Rent Expense $3,000
- Credit Wages Expense $10,000
- Credit Supplies Expense $2,000
After these first two entries, your Income Summary balance equals your net income (or net loss). In this example, $25,000 minus $15,000 = $10,000 net income, sitting in Income Summary as a credit balance And that's really what it comes down to..
3. Close Income Summary to Retained Earnings
This is the step students forget. You take whatever's in Income Summary and close it to Retained Earnings Not complicated — just consistent..
If Income Summary has a $10,000 credit balance (net income):
- Debit Income Summary $10,000
- Credit Retained Earnings $10,000
If it was a net loss, you'd flip it — debit Retained Earnings and credit Income Summary.
4. Close Dividends to Retained Earnings
Dividends aren't an expense, which trips people up. They directly reduce retained earnings, so we close them out the same way.
- Debit Retained Earnings
- Credit Dividends
After this entry, every temporary account is back to zero, and the permanent accounts (including updated Retained Earnings) carry forward.
Common Mistakes Students Make in Milestone 2
I've graded, reviewed, and helped with enough of these to know exactly where things go sideways. Here are the big ones.
Closing the Wrong Accounts
Assets, liabilities, and the capital or common stock accounts do not get closed. Only revenues, expenses, and dividends. If you find yourself writing a closing entry for Cash or Accounts Payable, stop and recheck.
Forgetting to Update for Adjustments
Milestone 2 typically uses the adjusted trial balance, not the unadjusted one. If you skip adjusting entries from Milestone 1, your revenue and expense totals will be wrong, and your closing entries will be wrong too. Always start from the post-adjustment balances.
Mixing Up Debits and Credits on Income Summary
This one's so common it's almost a rite of passage. Here's a quick memory trick: when you close revenues (credits), you debit them. And when you close expenses (debits), you credit them. In real terms, income Summary always takes the opposite side. If you keep that pattern in your head, you'll rarely get it backward But it adds up..
Skipping the Dividends Entry
Some students close revenues and expenses, update retained earnings, and then... Dividends just sit there in the ledger with a balance, which would carry into the next period and mess everything up. stop. Always do all four entries.
A Quick Example From Start to Finish
Let's say after adjustments, your trial balance shows:
- Service Revenue: $30,000 (credit)
- Wages Expense: $12,000 (debit)
- Rent Expense: $6,000 (debit)
- Utilities Expense: $2,000 (debit)
- Dividends: $4,000 (debit)
Your closing entries would be:
- Debit Service Revenue $30,000 / Credit Income Summary $30,000
- Debit Income Summary $20,000 / Credit Wages Expense $12,000 / Credit Rent Expense $6,000 / Credit Utilities Expense $2,000
- Debit Income Summary $10,000 / Credit Retained Earnings $10,000 (net income)
- Debit Retained Earnings $4,000 / Credit Dividends $4,000
After all four, retained earnings has increased by $6,000, every temporary account is at zero, and the books are ready for the next period.
What Actually Helps in Practice
A few things that genuinely make this easier, especially under time pressure.
Start with the adjusted trial balance and literally check off each account as you close it. It's not glamorous, but it works. Missing one account is the most common reason totals don't match later.
Write out the four steps on a sticky note before you start your worksheet. Seriously. The order matters, and having it visible prevents you from doing step 3 before step 1 And it works..
Check your logic, not just your numbers. If you closed an account and the balance on the trial balance was a debit, you should have credited it. If it was a credit, you should have debited it. This single check catches most errors Simple, but easy to overlook..
Don't round until the end. If your numbers aren't matching exactly, it's almost always a rounding issue or a missed account, not a conceptual one. Go back to the trial balance and re-add That's the whole idea..
FAQ
Do closing entries happen every month or just at year-end?
Technically, closing entries happen at the end of every accounting period — monthly, quarterly, or annually — depending on how the company does its books. Even so, in ACC 201, you're usually working with a monthly or annual cycle. The process is identical either way Easy to understand, harder to ignore..
What happens if I forget a closing entry?
That account keeps its balance into the next period. If it's a revenue or expense, your income for the next period will look inflated. If it's dividends, your retained earnings will be wrong Turns out it matters..
It’s not catastrophic, but it does affect the equity section and can cause the trial balance to be out of balance when the new period begins.
Once the four closing steps are completed, the post‑closing trial balance should display zero balances for Service Revenue, Wages Expense, Rent Expense, Utilities Expense, and Dividends. This verification step is essential; it confirms that the temporary accounts have been properly cleared and that only permanent accounts remain active.
Short version: it depends. Long version — keep reading.
A practical habit is to run a quick scan of the post‑closing trial balance after each closing batch. If any temporary account still carries a balance, the error can be traced back to the specific entry that was missed. Many accounting systems will automatically generate this report, but understanding the underlying logic lets you spot anomalies even when the software does the heavy lifting The details matter here..
Not the most exciting part, but easily the most useful.
Understanding why the process matters also sharpens your analytical mindset. By transferring net income into retained earnings, you preserve the true earnings history of the business, which is the figure stakeholders rely on for performance assessment. Dividends, when cleared, prevent an artificial reduction in equity that would otherwise distort comparisons across periods.
In practice, the most reliable approach is to treat the closing sequence as a checklist rather than a series of isolated journal entries. That's why verify that the total debits equal the total credits at each stage, and confirm that the Income Summary account reflects the net result before it is transferred to retained earnings. This disciplined verification eliminates the most common sources of mismatch and saves time during the subsequent accounting cycle.
Conclusion
The four closing entries serve as the bridge between accounting periods, resetting temporary accounts, updating retained earnings, and ensuring that financial statements remain accurate and comparable. By consistently applying the checklist, confirming logical relationships, and validating the post‑closing trial balance, you can close the books with confidence and lay a solid foundation for the next period’s transactions.
