- The adjusted trial balance (ATB) is the trial balance after all period-end adjusting entries are booked; every workpaper, misstatement summary, and financial statement ties back to it.
- Every adjustment fits one of four buckets: accruals, deferrals, estimates, or reclassifications. The bucket shapes how it gets tested.
- PCAOB inspectors keep citing journal entry testing, and it's where fraud risk tends to hide.
- Mapping the ATB into the financial statements is an assertion-driven exercise, not a copy-paste job.
It's the Friday before the report goes out. Your senior is pinging you about a tie-out that's off by $1,500, the lead sheet doesn't match the summary of audit differences, and somewhere in the chain of workpapers a reclassification didn't make it into the final numbers. Every thread you pull leads back to the same file: the adjusted trial balance.
The ATB is the spine of the engagement, and most tie-out pain comes from treating it like just another schedule instead of the thing everything else has to agree with. This article covers what the ATB actually is, how to prepare and validate one without creating downstream review pain, and how it maps into the financial statements under the assertion framework.
What is an adjusted trial balance?
The adjusted trial balance is the trial balance you get after every period-end adjusting entry has been booked. It's the version of the ledger that actually reflects the economics of the period, and it's what the financial statements get built from.
Three buckets of adjustments typically get layered onto the client's raw ledger:
- Client-initiated entries: the period-end accruals, deferrals, and depreciation from the close process.
- Auditor-proposed entries: adjusting journal entries management has accepted.
- Reclassification entries: presentation fixes that don't touch net income.
Here's why this matters in review: the ATB is what everything else ties to. Workpaper amounts agree to it, misstatements get summarized against it, and every supporting schedule cross-references back to it. When the file is clean, nobody thinks about the ATB at all. When it isn't, it's the only thing anyone thinks about.
Once finalized, the ATB carries the numbers that hit the financial statements and ties those statements back to the underlying accounting records.
What is the difference between an adjusted and unadjusted trial balance?
The two versions do different jobs in the audit file, and treating them interchangeably is where tie-out problems usually start.
Where the unadjusted trial balance fits
The unadjusted trial balance (UTB) is the starting point: the client's general ledger balances as of period-end, before any adjusting entries. It arrives as a PBC item, usually alongside supporting schedules like bank reconciliations, accounts receivable aging, fixed asset roll-forwards, and deferred revenue schedules.
Validation comes first. If the journal entry population and the general ledger don't fully reconcile, every downstream tie-out inherits the gap, and a sub-ledger to general-ledger break is an audit risk in its own right. The mechanics of the completeness check are covered in the preparation walkthrough below.
Once the UTB holds up, the adjustments get layered in.
Changes after adjusting entries are posted
The ATB picks up every adjustment the engagement requires. New accounts show up for the first time: interest receivable, accumulated depreciation, salaries payable. Existing balances shift. And the adjusted totals will usually be bigger than the unadjusted totals, because new accounts expand the population.
There's also a post-closing trial balance, prepared after closing entries zero out the temporary accounts; it ties to the opening balances for the next period.
Why does the adjusted trial balance matter in an audit?
The ATB is where evidence, misstatements, and the final statements meet. When the tie-out is weak, review slows down, conclusions get harder to support, and the pressure shows up in three places.
The trial balance is company-produced information
The ATB comes from the client, which means it gets tested, not assumed. Current PCAOB guidance requires company-produced information used as audit evidence to be tested for accuracy and completeness, with controls testing as the alternative route. The trial balance is the highest-stakes example of that rule because everything else in the file rests on it.
Uncorrected misstatements add up
Uncorrected misstatements are evaluated against the financial statements as a whole and against the specific accounts and disclosures affected. When a client declines a proposed entry, those differences accumulate and get assessed against materiality, both individually and in aggregate. Offsetting material misstatements can also point to weaknesses in internal control.
Journal entry testing is a PCAOB focus area
Fraud that reaches the financial statements often runs through journal entries: management override of controls usually shows up as an inappropriate entry somewhere in the population. Firms keep getting this testing wrong in inspections, badly enough that PCAOB staff published a dedicated January 2025 Audit Focus on journal entry testing, and the staff's 2024 inspection update lists consideration of fraud as a recurring deficiency area. Among the common failures the staff calls out is not testing the completeness of the journal entry population, which is exactly the validation work the trial balance process is supposed to anchor.
How do you prepare an adjusted trial balance?
The sequence matters: a skipped validation step at the front is what turns into the Friday-afternoon tie-out scramble at the back.
Obtain and validate the unadjusted trial balance
Once the client's trial balance and supporting schedules are in, validation starts with journal entry population completeness: recalculate each account's balance from the prior-year trial balance plus current-year journal entry activity, and compare the results to what the client provided. Variances get investigated before anything else gets built on those numbers.
Workpapers are headed, dated, initialed, indexed, and cross-referenced as they're built, and standard review checklists treat agreement to the trial balance as a foundational question.
From there, attention turns to whether the balances themselves are properly stated.
Identify and record adjusting entries
Each account on the trial balance gets a look: does the balance reflect what actually happened in the period? The usual suspects are the period-end categories: unrecorded payables, interest on loans, prepaid amortization, reserves and allowances, and tax accruals. Each adjustment is calculated, supported by evidence, numbered sequentially, and posted to the adjustment columns with the same care as a formal book entry.
Adjusting entries affect net income because they involve at least one income statement account; reclassification entries move amounts between accounts without changing the bottom line. Keeping the two separate matters at review, because the summary of audit differences turns on what moved net income.
Up to this point, the work is bookkeeping any controller could do. What makes it audit work is the layer that comes next: examining the entries themselves for signs of fraud.
Test journal entries for fraud risk
This phase has no equivalent in a pure bookkeeping workflow. Fraud-related misstatements often involve unauthorized journal entries, and they can also involve adjustments made outside the formal journal entry process. Certain characteristics draw closer scrutiny: entries made by people who don't normally make journal entries, entries recorded at period-end with little explanation, round numbers, and entries to accounts that carry intercompany transactions.
Top-side and post-closing entries carry particular risk because they're made outside the normal transaction cycle, which is exactly why they get extra attention during review.
After fraud-risk testing, the adjustments are ready for final posting.
Generate and verify the adjusted trial balance
Once all approved adjusting entries are posted, the team foots the general journal and general ledger and prepares the ATB from the resulting balances. Total debits must equal total credits at the adjusted level. The workpaper review checklist closes the loop: do amounts agree with the trial balance, are conclusions supported, and are misstatements adequately summarized?
How Fieldguide keeps the tie-out in one place
The catch with the spreadsheet version of this workflow is that the trial balance, the adjusting entries, and the workpapers all live in different files, and the tie-out is whatever the team reconstructs at review. Fieldguide keeps them in one place: the trial balance imports directly into the engagement, adjusting entries are tracked against it, and workpapers reference the same engagement data instead of a copy someone exported in January. AI Actions generate analysis across an entire column in one click, and the Agent Workforce executes multi-step engagement work, with each run producing a Trace showing its inputs, outputs, and reasoning, so the documentation is a byproduct of the work rather than a write-up after it. Practitioners review and approve the outputs; the conclusions stay theirs.
What are the common types of adjusting entries?
The bucket an adjustment lands in determines the audit response: an accrual gets tested for completeness, an estimate gets tested for the judgment behind it. The mechanics look similar across all four, usually one income statement account paired with one balance sheet account and typically no cash movement. The risk profiles don't.
Accrual adjusting entries
Accruals capture revenues earned or expenses incurred that haven't been recorded yet: accrued wages earned before year-end but unpaid, accrued interest on outstanding debt, unbilled revenue on completed engagements. Accrued expenses are a high-risk area for understatement, which is why completeness drives the testing approach and why auditors run search-for-unrecorded-liabilities procedures after year-end.
Deferral adjusting entries
Deferrals move the opposite direction: cash has already changed hands, and the adjusting entry allocates it to the correct period. A SaaS company collecting annual subscriptions in advance generally records a contract liability, often called deferred or unearned revenue, and recognizes revenue as performance obligations are satisfied. An annual insurance premium paid upfront gets amortized from prepaid expense to insurance expense each month.
Estimates and allowances
Estimates are where judgment lives: depreciation on fixed assets, amortization of intangibles, and the allowance for credit losses under the current CECL model. The bad debt allowance is one of the most judgment-intensive audit estimates, requiring evaluation of methodology, historical loss rates, and forward-looking factors. Inventory write-downs to lower of cost or net realizable value fall here too.
Reclassifications and error corrections
Reclassifying the current portion of long-term debt from long-term liabilities to current liabilities is a presentation fix with no income statement impact. Prior-period error corrections are a different animal; they may require restating prior financial statements when the errors are material.
Adjusted trial balance example
Practitioners usually use a three-column worksheet: unadjusted balance, adjustments, and adjusted balance. Consider a simplified trial balance where the UTB totals $34,000 in debits and credits, with five adjusting entries applied:
- Accrued interest: Interest Receivable +$140 and Interest Revenue +$140, both new accounts.
- Previously deferred revenue earned: Unearned Revenue down $600 to $3,400 and Service Revenue up $600 to $10,100.
- Supplies consumed: Supplies down $100 to $400 and Supplies Expense +$100, a new account.
- Equipment depreciation: Depreciation Expense +$75 and Accumulated Depreciation +$75, both new accounts.
- Accrued salaries: Salaries Expense up $1,500 to $5,100 and Salaries Payable +$1,500, a new account.
Total adjustments come to $2,415 on each side, and the ATB now totals $35,715 in debits and credits, up from $34,000 unadjusted.
The moving totals are what the reviewer ties out, which is why seeing the path from unadjusted to adjusted in one view matters at review.
How does the adjusted trial balance flow into the financial statements?
The financial statements get built from the ATB, and the mapping sequence matters: income statement first, then statement of retained earnings or equity, then balance sheet, then statement of cash flows. Each ATB account maps to a financial statement line item, with presentation and classification following the applicable accounting guidance.
The assertion framework shapes what gets checked at each step. Completeness is a core concern: have any transactions or accounts been improperly excluded from the statements? Presentation and disclosure governs classification, whether each account lands on the right line item. And before signing off, the auditor reads the statements and performs final analytical procedures to evaluate whether they're free of material misstatement as a whole.
A reclassification that moves an ATB account to a different line item than the prior period draws audit scrutiny, and material changes get disclosed.
In most workflows, the statements get drafted in Word from an Excel support file, and every late adjustment means updating both and re-checking the tie-out. In Fieldguide, Field Financials prepares the statements directly from the trial balance, no exports and no manual reconciliation, and practitioners review the draft before anything goes out.
Run the adjusted trial balance inside the engagement, not beside it
