What it looks like
Accounts are listed from assets through equity, income and expenses. Each shows its balance on its normal side. At the bottom the totals appear. In a healthy set of books, they match.
Run it as of a date, usually month end or year end. Compare to a prior date to see which accounts moved.
What it proves
If debits equal credits, the arithmetic of your entries is consistent. That is the extent of the proof. Modern software enforces balanced entries, so the trial balance nearly always balances. If it does not, there is a data problem, such as a corrupted import or a conversion error.
It does not prove that each amount is in the correct account or that every transaction is recorded.
Reading it for problems
Scan each account against what you expect. Bank balances should match statements. Receivables and payables should match their detail reports. Look for accounts on the wrong side, such as a negative bank balance or an expense with a credit balance. Check for accounts with names that you do not recognize.
Check liabilities for payroll taxes, sales tax and loans against filings and statements.
A trial balance for a real estate office or rental properties
Real estate books have a few accounts that come in matched pairs, and the trial balance is the fastest place to check them. For a brokerage, money held in escrow sits in a trust bank account (an asset) and the same amount appears as escrow owed to clients (a liability). On the trial balance the two should be equal. If they are not, a deposit or disbursement was recorded on one side only.
For rental properties, tenants' security deposits work the same way: the deposit bank account and the security deposits held liability should match. New Jersey requires security deposits to be kept in a separate account, so a gap here is worth fixing quickly. Also check that rent collected in advance shows as a liability rather than income, and that each property's mortgage balance matches the lender's statement.
A short example: Escrow bank account, debit $48,000. Escrow deposits owed to clients, credit $48,000. Security deposit bank account, debit $9,600. Security deposits held, credit $9,600. Both pairs match, so the money you hold for other people is fully accounted for.
Adjusted and post-closing versions
An unadjusted trial balance is run before adjusting entries. After depreciation, accruals and other adjustments, you have an adjusted trial balance, which feeds the profit and loss and the balance sheet. Accountants may also prepare a post-closing version, which includes only balance sheet accounts after the year's profit is rolled into equity.
Comparing the unadjusted and adjusted versions shows the impact of your period-end entries.
Practical uses
Give your tax preparer an end-of-year trial balance. It lets them see the whole picture on one page and ask targeted questions. Use it before applying for a loan to confirm that the data lenders will see is clean.
If you are learning accounting, build one by hand from a handful of sample entries. Seeing how balances roll up helps all the other reports make sense.
After you reconcile, run the trial balance and take two minutes to compare it with last month. Highlight any account that changed by a large amount and write a one-line reason. Check that accounts like uncategorized income, ask my accountant and opening balance equity are empty or explained. This habit turns a technical report into a simple control and gives your bookkeeper or CPA a trail of notes to follow.
Save a copy of the year-end version as a PDF or spreadsheet. If a question comes up later about what the books said on that date, the saved report answers it even if later edits have changed live reports.
Worked example with numbers
A tiny trial balance lists debit balances of cash $5,000, receivables $2,000 and rent expense $1,000, totaling $8,000. Credit balances are payables $1,500, owner equity $2,500 and sales $4,000, totaling $8,000. Debits equal credits, so the books are in balance.
If the credit column were $7,900, the $100 gap points to a one-sided entry, a transposition, or a deleted transaction. Divide the difference by nine to test for a transposition: a gap divisible by 9 often means digits were swapped.
Check your work
After correcting the difference, rerun the trial balance and compare it to last month's. Large unexplained swings in any account deserve a look.
Common questions
Is a trial balance a financial statement?
No. It is a working report. The financial statements are built from it.
Why might it be out of balance?
Usually due to imports, system errors or incomplete conversions. Entries made normally are balanced.
Do I need one?
Not for daily work, but it is useful at close and for your accountant.
