Review and resources
Beacon Design has been in business for 1 year. On December 31, its trial balance reports total debits of $186,400 and total credits of $186,400. Every recorded entry has support, uses the correct accounts, and appears in the total.
The trial balance accurately summarizes the transactions posted so far, but some balances are out of date. Beacon completed service on December 30 that it has not billed. Employees also worked in December for wages that Beacon will pay on January 5. An insurance policy has partly expired, a client advance has been partly earned, and Beacon has used its equipment for the year. These events must be reflected before Beacon prepares its financial statements.
Reporting periods and the events that cross them
A business operates continuously, but financial statements cover stated periods. One activity may span several months, pay periods, or calendar years. Accountants must divide that activity among the periods it affects.
The reporting date creates a question: how much of an activity belongs in the current period? The original cash entry or invoice may not answer it. The accountant may also need contracts, completion reports, timesheets, schedules, or physical counts. Adjusting entries use that evidence to bring the accounts up to date.
Why cash timing is not enough
Under cash-basis accounting, an entity records revenue when it receives cash and records expense when it pays cash. Those records show when cash moved, but cash movement and business activity do not always occur in the same period.
Beacon completed $4,800 of design service on December 30. It will send the invoice on January 3 and expects payment by January 20. Beacon's employees completed $2,700 of work in December that Beacon will pay as part of the January 5 payroll.
Under the cash basis, neither the $4,800 of service nor the $2,700 of wages appears on the December financial statements. December revenue is $4,800 too low, and December expense is $2,700 too low. The net effect is a $2,100 understatement of December income. January then reports revenue and expense from work completed in the prior year.
Accrual-basis accounting and adjusting entries
December financial statements must include the service Beacon completed and the wages it incurred in December, even though the related cash moves in January.
Accrual-basis accounting reports revenue when an entity earns it and reports expense when it consumes a resource or incurs an obligation. The related cash receipt or payment may occur in the same period or another one. Financial statements prepared under US GAAP use accrual-basis accounting. The statement of cash flows separately reports cash receipts and payments.
Throughout this course, earned is shorthand for meeting the applicable US GAAP revenue-recognition requirements. For revenue from contracts with customers, Chapter 8 explains when a performance obligation is satisfied.
An adjusting entry updates account balances for information available at the reporting date, before the statements are prepared. It records the difference between what the accounts currently show and what they must report at period end.
Why account balances need adjustment
An adjusting entry records period-end information that the ledger does not yet report correctly. Common reasons an adjusting entry is required include:
- Activity has occurred but has not been recorded. Accrued revenue and accrued expense record activity that belongs in the current period.
- A previously recorded balance is out of date. Prepaid expense and unearned revenue update an existing asset or liability for the portion used or earned.
- A period-end amount requires allocation or estimation. Depreciation and other estimates use a measurement method and current evidence.
An adjustment may reflect more than one of these reasons. A correction, by contrast, fixes an error in an earlier entry; it is not a separate type of adjusting entry.
Determine the adjustment from required and recorded balances
Use three steps to determine an adjusting entry.
Determine the account's required ending balance at the reporting date. Use evidence such as completion reports, timesheets, contracts, schedules, or physical counts.
Find the recorded balance in the ledger.
Prepare and record the adjusting entry. Use the difference to determine the amount and direction of the account change. After the entry is posted, the account should report the required balance.
For Beacon's unpaid wages, the timesheets support a required $2,700 credit balance in Wages Payable. Beacon's ledger shows no balance for those wages. Beacon therefore credits Wages Payable for $2,700 and debits Wages Expense for $2,700.
The rest of this chapter applies the same method. The categories that follow help identify the accounts and evidence to examine; they do not replace the comparison of required and recorded balances.
The four timing patterns: accruals and deferrals
Timing adjustments fall into four patterns. A deferral is a cash-first pattern: the company initially records an asset or liability and recognizes the related expense or revenue in a later period. An accrual is an activity-first pattern: the company records revenue or expense before the related cash moves. Use two questions to identify the pattern: Did cash move before or after the economic activity? Did the company provide goods or services, or did it receive or use resources or services?
| Company's role | Cash first: deferral | Activity first: accrual |
|---|---|---|
| Provides goods or services | Unearned (deferred) revenue Reduce the liability as the company performs. | Accrued revenue Record revenue and the related asset. |
| Receives or uses resources or services | Prepaid expense Reduce the asset as the company uses it. | Accrued expense Record an expense and a payable. |
Both activity-first patterns are accruals. They record activity missing from the ledger. An account may contain other activity. Accounts Receivable, for example, may include invoiced sales before Beacon adds one uninvoiced job. Beacon's $4,800 of uninvoiced services is accrued revenue, and its $2,700 of unpaid wages is an accrued expense.
Both cash-first patterns are deferrals. They adjust an amount already in the ledger. The cash transaction records a prepaid asset or a liability, such as Unearned Service Revenue. As Beacon uses the prepaid resource or performs for the customer, the remaining asset or liability decreases.
Each timing pattern connects one or more income-statement accounts with one or more balance-sheet accounts. For example, a payroll accrual may debit more than one expense account and credit more than one payroll liability. Other adjustments may use a different account structure.
Quick checkCash moved first, and Beacon still owes the customer service. Which timing pattern applies?
Answer: Unearned or deferred revenue. The company reports the remaining service obligation as a liability.
- Mistaken idea: A deferral means recording nothing until later
Correction: Deferring revenue or expense does not postpone recording cash. Record a prepaid asset when paying for future benefits, or a liability when receiving an advance for future work. Later use or performance produces the expense or revenue.

Accrued revenue and accrued expenses
Return to Beacon's year end. Beacon performed $4,800 of design service on December 30 and has not invoiced it.
| Event | Activity date | Reporting date | Billing, collection, or payment |
|---|---|---|---|
| Design service | December 30: Beacon completes $4,800 of work. | December 31: record revenue and a receivable. | Invoice January 3; collect January 20. |
| Employee service | Employees complete $2,700 of work in December. | December 31: record expense and a payable. | Pay January 5. |
The activity date determines the reporting period. The later invoice, collection, and payment settle the resulting receivable or payable.
The required ending balance in Accounts Receivable includes a $4,800 claim because Beacon has done the work and its right to payment is unconditional under the contract. Sending the invoice is an administrative step. The recorded balance includes nothing for this job, so the adjustment records the $4,800 difference:
The credit puts the $4,800 of revenue in December, when the work was done, and where the cash method left it out.
When the customer pays on January 20, Beacon debits Cash and credits Accounts Receivable. Collection settles the existing claim; it does not create revenue a second time.
Beacon's December wages require a separate accrued-expense adjustment. The required ending balance in Wages Payable is $2,700, the amount that employees earned and Beacon owes. The recorded balance includes nothing for this work because payroll does not run until January 5. The adjustment records the $2,700 difference:
When Beacon pays the payroll on January 5, it debits Wages Payable and credits Cash. The payment settles the liability recorded on December 31.
Prepaid expenses and unearned (deferred) revenue
In both accrual examples, the ledger contained no amount for the year-end event, so the adjustment was the full amount. The deferral patterns start with a recorded balance and update it for the portion used or performed.
Beacon's Prepaid Insurance account shows how the three steps apply to a deferral.
On April 1, Beacon paid $12,000 for 12 months of insurance coverage running through March 31 of the following year. Beacon debited Prepaid Insurance, and each month of coverage costs $1,000.
Use the three-step method before recording the entry:
The T-account shows how the adjustment produces the required ending balance:
This comparison is why the accountant determines the required balance from independent evidence before relying on the ledger balance.
The entry debits Insurance Expense for $9,000 and credits Prepaid Insurance for $9,000. The remaining $3,000 is an asset because Beacon still has 3 months of coverage.
Suppose Beacon accidentally recorded the $12,000 policy as $12,500. Recording $9,000 of expense would leave a $3,500 asset, but the policy supports only $3,000 of remaining coverage. The $500 difference is a recording error that Beacon must investigate and correct separately. It is not additional insurance expense.
Companies use account reconciliations, schedules, physical counts, and cutoff procedures to determine required balances. An equal trial balance does not identify a missing adjustment or an unsupported balance.
Quick checkThe policy supports $3,000 of Prepaid Insurance, but the ledger shows $3,500 after the normal expense entry. Should Beacon record the extra $500 as Insurance Expense?
Answer: No. The unsupported $500 signals a recording error that Beacon must investigate and correct separately.
The client advance begins with a liability rather than an asset. On November 1, a client paid Beacon $6,000 in advance for 6 months of design support running from November 1 through April 30. Beacon recorded Unearned Service Revenue, a liability, because it owed the client 6 months of work.
At December 31, Beacon has performed 2 of the 6 months and still owes 4 months of support. The required ending balance in Unearned Service Revenue is therefore a $4,000 credit (4 months × $1,000). The recorded balance is the original $6,000 credit. The adjustment is the $2,000 difference.
The adjusting entry records the $2,000 decrease in the liability and the $2,000 of revenue for the support Beacon has provided:
The $2,000 is service revenue, earned by performing 2 months of the contract.
Neither the insurance adjustment nor the client-advance adjustment changes Cash because Beacon recorded both cash transactions earlier. Each adjustment reduces an asset or liability to the amount that remains on December 31.
If Beacon had adjusted insurance monthly through November, Prepaid Insurance would show $4,000 ($12,000 less 8 months at $1,000 per month) before the December entry. The required ending balance would still be $3,000, so the December adjustment would be $1,000:
Prepaid Insurance ends at $3,000 whether Beacon adjusts once at year-end or once each month. Insurance Expense for the year also totals $9,000. The frequency of the adjustments changes the amount left for the final entry, not the final annual balances. The accountant must therefore read the ledger rather than assume that the full annual adjustment is still needed.
Estimates and depreciation
Depreciation is not one of the four timing patterns. Cash timing does not determine its amount. Instead, the company allocates cost using a measurement method and supported estimates. Some inputs cannot be known exactly, so the company documents the evidence used to estimate them.
Beacon's approved timesheets provide the $2,700 wage accrual. Depreciation is different. The equipment invoice provides its cost. No invoice states how long Beacon will use the equipment or how much it will recover when use ends. Beacon estimates the useful life and salvage value from the equipment's expected use, condition, maintenance, technological change, and available market information.
An estimate is not a guess chosen to reach a desired income amount. It is a measurement based on the best evidence available at the reporting date. Different reasonable assumptions can produce different amounts. Beacon must document its method and assumptions and revise the estimate when new evidence changes what it reasonably expects.
Quick checkWhy is the $2,700 wage accrual different from estimated depreciation?
Answer: Approved timesheets determine the wage amount. Depreciation also requires supported assumptions about useful life and salvage value.
Beacon bought equipment on January 2 for $18,000. It expects to use the equipment for 5 years and recover $3,000 at the end. The depreciable amount is $15,000 ($18,000 - $3,000). Beacon uses straight-line depreciation, one method permitted under US GAAP. It assigns $3,000 to each full year ($15,000 ÷ 5 years). Unit 6 addresses later changes in these estimates.
The credit uses Accumulated Depreciation, a contra account, rather than reducing Equipment. A contra account has the opposite normal balance from its related account and reduces that account for presentation.
Under these assumptions, Accumulated Depreciation has a required credit balance of $3,000 after year 1, $6,000 after year 2, and $9,000 after year 3. A depreciation schedule provides an independent total to compare with the ledger.
The balance sheet reports both accounts and the difference between them:
| Balance sheet at December 31 | Amount |
|---|---|
| Equipment | $18,000 |
| Less: accumulated depreciation | (3,000) |
| Carrying amount | $15,000 |
The carrying amount is the amount at which the asset is reported once accumulated depreciation has been deducted. It is not what the equipment would sell for, and it is not what Beacon would pay to replace it. It is the part of the cost Beacon has not yet assigned to an expense.
Why not reduce Equipment directly? The two balances answer different questions. Equipment reports the asset's cost. Accumulated Depreciation reports how much of that cost Beacon has allocated to expense. A $15,000 carrying amount by itself could describe a $16,000 asset that has received little depreciation or an $80,000 asset that has received much more. Reporting cost and accumulated depreciation separately preserves information that the net amount alone would hide. Unit 4 uses the same presentation idea when an allowance for credit losses is deducted from gross receivables.
- Mistaken idea: Depreciation measures an asset's market-value decline
Correction: Depreciation allocates an asset's depreciable cost to the periods that use it. It does not estimate the price a buyer would pay for the asset today.
Read the full explanation
The schedule can also reveal a missed entry. Suppose Beacon records $3,000 in years 1 and 2 but misses year 3. After Beacon records the normal $3,000 year 4 entry, the ledger contains:
The depreciation schedule requires a $12,000 credit balance at the end of year 4. The $9,000 ledger balance is $3,000 too low because the year 3 credit is missing.
Beacon should not record the $3,000 ledger-to-schedule difference as year 4 Depreciation Expense. The difference comes from the missed year 3 entry. Beacon must identify the cause and apply the guidance for correcting a prior-period error. The balance comparison finds the discrepancy; it does not determine the correction.
Quick checkBeacon missed last year's depreciation. Why should it not automatically record the entire ledger-to-schedule difference as this year's Depreciation Expense?
Answer: Part of the difference belongs to the prior year. Recording the full amount this year could misstate current-year income.
If Beacon omits the year 4 depreciation entry, annual net income, assets, and equity are each overstated by $3,000. Liabilities are not affected.
Where accounting judgment enters
The amount of judgment depends on the adjustment. Beacon's completion report directly supports the amount and completion date of the $4,800 service. Other adjustments require the accountant to evaluate whether the records are complete, measure an uncertain amount, or determine whether and when an event should be recorded.
Completeness. Beacon's missing wage accrual leaves the trial balance equal. Account reconciliations, cutoff work, and review procedures help identify activity that has not been recorded.
Measurement. An estimate requires a method, relevant evidence, and supported assumptions. The evidence may support one amount or a range of reasonable amounts, depending on the estimate. Beacon's useful-life and salvage-value estimates affect its depreciation calculation.
Recognition and period. Contract terms, completion evidence, and the applicable accounting guidance determine whether and when an event should be recorded. Beacon's completion report supports recording the $4,800 service in December. When the facts require judgment, the accountant documents the evidence and the reason for the conclusion.
The effect of an omitted adjustment on the statements
Because the timing adjustments in these examples connect income-statement and balance-sheet accounts, omitting one misstates both statements.
If Beacon omits the $4,800 revenue accrual, December's net income is understated by $4,800. Assets are understated by the same $4,800, and so is equity, since net income closes into retained earnings. If Beacon omits the $2,700 wage accrual, net income is overstated by $2,700, and liabilities are understated by the same amount.
The examples have the following effects:
| Omission | Net income | Assets | Liabilities | Equity |
|---|---|---|---|---|
| The $4,800 revenue accrual | understated $4,800 | understated $4,800 | no effect | understated $4,800 |
| The $2,700 wage accrual | overstated $2,700 | no effect | understated $2,700 | overstated $2,700 |
| The $9,000 insurance adjustment | overstated $9,000 | overstated $9,000 | no effect | overstated $9,000 |
| The $2,000 unearned-revenue adjustment | understated $2,000 | no effect | overstated $2,000 | understated $2,000 |
| Both accruals | understated $2,100 | understated $4,800 | understated $2,700 | understated $2,100 |
The income statement is off by $2,100, which is far less than either error on its own, while both balance-sheet lines are wrong by considerably more. A reviewer scanning net income for a large variance sees nothing.
Review an adjustment before using it
A colleague or software tool may prepare an adjusting entry. The reviewer remains responsible for the evidence, checks, and final decision. Before accepting the entry, the reviewer should answer these questions:
- Which entity and reporting date does the entry cover?
- Which documents and accounting guidance support it?
- Does an independent calculation produce the same amount?
- Do the date, accounts, and debit and credit sides match the underlying event?
- Is any required fact missing or inconsistent with another source?
Suppose a proposed entry debits Wages Expense and credits Cash for $2,700 on December 31. The entry balances, and the timesheets support the expense amount. The January 5 pay date shows that cash did not leave Beacon in December, so the credit is wrong. The reviewer changes the credit to Wages Payable and records the timesheets and pay date as support.
If the timesheets are missing or conflict with the payroll record, the reviewer cannot support the $2,700. The entry needs more evidence before it can be accepted.
Beacon's original trial balance had equal debit and credit totals, but several balances were incomplete or out of date. The five period-end adjustments add missing activity, update recorded balances, and allocate equipment cost to the period. Each entry preserves equality between total debits and total credits while producing balances that reflect the reporting-date information.
