Timing Adjustments and Period-End Matching

Learning objectives

By the end of this chapter you should be able to:

• Calculate and record accruals, prepayments, accrued income, and deferred income so that profit reflects the correct period.
• Prepare period-end adjusting journals and update statement extracts to show the correct assets, liabilities, income, and expenses.
• Explain how period-end matching improves reported profit by linking income and related costs to the period in which they arise.
• Analyse the effect of timing adjustments on profit, assets, liabilities, and equity, using the accounting equation.
• Identify and avoid common year-end cut-off and classification errors.

Overview & key concepts

Most businesses do not receive or pay cash at exactly the same time as they earn income or consume resources. If accounts were prepared purely from cash movements, profit would fluctuate for timing reasons rather than reflecting underlying performance.

Period-end timing adjustments correct this by ensuring that:

• expenses are recognised when resources are consumed (not simply when paid), and
• income is recognised when earned (not simply when received).

These adjustments are made at the reporting date and affect both profit and the statement of financial position.

The accounting equation link

Every adjustment must keep the accounting equation in balance:

Assets = Liabilities + Equity

Because profit increases equity (and expenses reduce it), timing adjustments often change equity indirectly through profit.

Core theory and frameworks

A quick way to get the journal right (exam method)

Start by asking: What must the statement of financial position show at the reporting date?

• If an obligation exists at year-end (something is owed), the adjustment usually creates or increases aliability.
• If a future benefit remains at year-end (something already paid or recognised will benefit a later period), the adjustment usually creates or increasesan asset.
• If income has been earned but not yet billed/collected, recognise anasset(amount due).
• If cash has been received before the work is done, recognise aliability(the remaining obligation to provide goods/services).

Then link it to profit:

• If the adjustment makes this year’s costs higher, profit falls (expense increases).
• If the adjustment makes this year’s income higher, profit rises (income increases).

Finally, post the double entry: one side to profit (income/expense) and the other to the year-end asset or liability that explains the timing difference.

1) Accruals (accrued expenses)

Meaning: An expense belongs to the current period but is unpaid and/or unrecorded at the reporting date.

Effect:

• Profit decreases (expense increases)
• Liabilities increase (amount owing)

Journal (period-end):
Dr Expense
Cr Accrued expenses (liability)

2) Prepayments (prepaid expenses)

Meaning: Cash has been paid (or an invoice recorded) but part of the benefit relates to a future period. The unused portion is an asset at the reporting date.

Effect:

• Profit increases compared with charging the full amount now (expense decreases)
• Assets increase (prepayment)

Journal (period-end):
Dr Prepayments (asset)
Cr Expense

Classification reminder: If the benefit will be consumed within 12 months of the reporting date, it is generally presented as current. If not, it is generally non-current (or split between current and non-current).

3) Accrued income

Meaning: Income has been earned in the current period but is unbilled and/or not yet received at the reporting date.

Effect:

• Profit increases (income increases)
• Assets increase (amount due)

Journal (period-end):
Dr Accrued income (asset)
Cr Income

4) Deferred income (income received in advance)

Meaning: Cash has been received (or a receivable recorded) before the related goods or services have been provided. The unearned portion is a liability at the reporting date (sometimes described as a “contract liability”).

Effect:

• Profit decreases compared with recognising all receipts as income (income decreases)
• Liabilities increase (obligation remaining)

Journal (period-end):
Dr Income
Cr Deferred income (liability)

Why cash causes confusion

Cash is about payment. Financial statements are about performance in the period. At the reporting date you are not “moving cash”; you are explaining what portion of amounts paid/received (or invoiced) belongs to this period and what portion belongs to another period. That is why the balancing entry is usually an asset (future benefit) or a liability (amount owed / performance still required), rather than bank.

Other high-yield period-end adjustments (often tested alongside timing)

Inventory and cost of sales cut-off

A quick check is to reconcile purchases to usage: start with what you had at the start of the year, add what came in, then remove what is still on hand at the end. The remainder is what was consumed/sold in the period (cost of sales).

Cost of sales = Opening inventory + Purchases − Closing inventory

Cut-off focuses on what belongs in this year’s numbers. For inventory, focus on whether the entity has taken control/ownership of the goods by the reporting date (often evidenced by delivery terms). If it has, the goods normally appear in closing inventory, with a matching payable if unpaid. For revenue, do not use “invoice issued” or “goods dispatched” as your trigger. Use the point when the customer obtains the goods or services under the contract terms (often aligned with delivery/acceptance conditions).

Interest on borrowings (notes payable / loans)

Interest is time-based and commonly accrues.

Interest = Principal × Annual rate × Time fraction

If interest is unpaid at period end:

Journal (period-end):
Dr Finance cost (interest expense)
Cr Interest payable / Accrued expenses

Impairment allowance on receivables (valuation adjustment)

Receivables may require an allowance where not all balances are expected to be collected. This is a valuation adjustment at the reporting date (an estimate reducing receivables to a realistic recoverable amount). It is not a timing cut-off item in the same sense as accruals/prepayments, but it is a common period-end adjustment.

Typical entries:

• To recognise/increase an allowance: Dr Impairment loss (expense), Cr Allowance (contra-asset)
• To write off a specific irrecoverable balance:
  • if an allowance exists: Dr Allowance, Cr Trade receivables
  • if no allowance exists: Dr Impairment loss, Cr Trade receivables

Dividends (equity-related)

Dividends are distributions to owners, not operating expenses. A dividend is recognised as a liability at the reporting date only when it has been appropriately authorised/approved and is no longer at the entity’s discretion. Amounts that are proposed or recommended but not yet authorised by the reporting date are not liabilities at that date.

Reversing entries (optional technique)

Some entities reverse selected adjusting entries on the first day of the next period to simplify processing, most commonly for accruals (for example, wages).

If an accrual was recorded at year-end:

Year-end adjustment:
Dr Expense
Cr Accrued expenses

Reversal next period (day 1):
Dr Accrued expenses
Cr Expense

Reversals are optional and should be used only where they improve clarity and control.

Worked example

Narrative scenario

ABC Ltd has a year-end of 31 December 20X8. During the year, the following information is available:

1. Electricity paid during the year: £5,400, of which £600 relates to January 20X9.
2. Wages for the final week of December, unpaid at year-end: £1,250.
3. Rent paid on 1 October for six months in advance, including tax at 20%: £1,440.
4. Insurance paid during the year: £2,400, with £500 relating to the next period.
5. Rent paid during the year: £9,000, with one month’s rent of £900 unpaid.
6. Consultancy income received/recorded: £7,800, with £1,100 of work completed but not yet invoiced.
7. Maintenance income received on 1 December for a four-month contract: £3,600.
8. Heating expense paid: £4,200, with £700 relating to April and May 20Y0.
9. Cleaning expense recorded: £3,100, with £450 still unpaid.
10. Service income recorded: £24,000, with £4,500 received in advance and £1,200 earned but not yet invoiced.

Assumption for item 3 (tax): the 20% tax is recoverable input tax and should not form part of rent expense. In many exam-style questions tax is ignored unless specifically mentioned; here it is included, so it must be separated from the expense.

Required

1. Calculate the electricity expense for the year and the prepayment.
2. Show the adjustment for wages accrual.
3. Calculate the rent expense for the year and the prepayment (item 3).
4. Show the adjustment for insurance prepayment.
5. Calculate the total rent expense charged to profit (item 5).
6. Show the adjustment for accrued income (consultancy).
7. Calculate the income for the current year and deferred income (maintenance contract).
8. Calculate the final expense figures for heating and cleaning.
9. Prepare the year-end journals for service income.

Solution

1) Electricity: prepayment

Paid during the year: £5,400
Amount relating to January 20X9: £600

Electricity expense (20X8) = £5,400 − £600 = £4,800

Prepayment at 31 December 20X8 = £600

Journal (year-end):
Dr Prepayments (electricity) £600
Cr Electricity expense £600

2) Wages: accrual

Unpaid wages at year-end: £1,250

Journal (year-end):
Dr Wages expense £1,250
Cr Accrued expenses (wages payable) £1,250

3) Rent paid in advance on 1 October (six months), including 20% tax

Gross cash paid: £1,440
Tax at 20% (recoverable): £240
Net rent: £1,200

Period covered: 1 October 20X8 to 31 March 20X9 (6 months)
Monthly net rent: £1,200 / 6 = £200

Expense in 20X8 (Oct–Dec): 3 × £200 = £600
Prepayment at 31 December 20X8 (Jan–Mar): 3 × £200 = £600

Rent expense (net) in 20X8 = £600

Prepayment (rent) at 31 December 20X8 = £600

Journal (timing adjustment, assuming net rent has been recorded as expense):
Dr Prepayments (rent) £600
Cr Rent expense £600

If the full gross £1,440 was incorrectly posted to rent expense, first reclassify the tax portion (no cash movement; this is not a second payment):

Reclassification journal:
Dr Input tax receivable £240
Cr Rent expense £240

(After this reclassification, the timing adjustment above is applied to the net rent figures.)

4) Insurance: prepayment

Paid during the year: £2,400
Amount relating to next period: £500

Insurance expense (20X8) = £2,400 − £500 = £1,900

Prepayment (insurance) at 31 December 20X8 = £500

Journal (year-end):
Dr Prepayments (insurance) £500
Cr Insurance expense £500

5) Rent: one month unpaid (accrual)

Rent paid during the year: £9,000
One month unpaid at year-end: £900

Total rent expense (20X8) = £9,000 + £900 = £9,900

Journal (year-end):
Dr Rent expense £900
Cr Accrued expenses (rent payable) £900

6) Consultancy income: accrued income

Consultancy income recorded/received: £7,800
Additional work completed but not invoiced: £1,100

Accrued income (consultancy) at 31 December 20X8 = £1,100

Journal (year-end):
Dr Accrued income (consultancy receivable) £1,100
Cr Consultancy income £1,100

7) Maintenance contract: deferred income

Cash received on 1 December: £3,600
Contract length: 4 months (Dec to Mar)
Monthly income: £3,600 / 4 = £900

Earned in 20X8 (December): £900
Unearned at 31 December 20X8 (Jan–Mar): 3 × £900 = £2,700

Maintenance income recognised in 20X8 = £900

Deferred income at 31 December 20X8 = £2,700

Journal (year-end):
Dr Maintenance income £2,700
Cr Deferred income £2,700

8) Heating and cleaning: final expense figures

Heating (prepayment)

Heating paid: £4,200
Relating to April and May 20Y0: £700 (future benefit at year-end)

Heating expense (20X8) = £4,200 − £700 = £3,500

Prepayment (heating) at 31 December 20X8 = £700

Journal (year-end):
Dr Prepayments (heating) £700
Cr Heating expense £700

Presentation note: this is an unusually long prepayment in the scenario. If it will be consumed more than 12 months after the reporting date, it would typically be presented as non-current (or split current/non-current if partly within 12 months).

Cleaning (accrual)

Cleaning expense recorded: £3,100
Still unpaid at year-end: £450

Cleaning expense (20X8) = £3,100 + £450 = £3,550

Journal (year-end):
Dr Cleaning expense £450
Cr Accrued expenses (cleaning payable) £450

9) Service income: received in advance and accrued income

Service income currently recorded: £24,000
Included in this is:

• Income received in advance (unearned): £4,500
• Income earned but not yet invoiced: £1,200

Correct service income = £24,000 − £4,500 + £1,200 = £20,700

Journals (year-end):

1. Defer unearned portion:
2. Dr Service income £4,500
3. Cr Deferred income £4,500
4. Accrue earned but unbilled portion:
5. Dr Accrued income £1,200
6. Cr Service income £1,200

Mini statement extract (closing balances created by the adjustments)

Receivables / accrued income assets (presentation depends on the format used):

• Consultancy earned but unbilled: £1,100
• Service income earned but unbilled: £1,200

Prepayments (assets):

• Electricity £600
• Rent £600
• Insurance £500
• Heating £700 (classification may be non-current depending on timing)

Accrued expenses (liabilities):

• Wages £1,250
• Rent £900
• Cleaning £450

Deferred income (liabilities):

• Maintenance £2,700
• Service income £4,500

Common pitfalls and misunderstandings

• Letting cash timing drive profit:Recognition depends on earning/consumption, not payment/receipt.
• Posting adjustments to bank:Most adjustments post to an asset or liability, not to cash.
• Mixing up prepayments and accruals:A prepayment is a remaining benefit (asset). An accrual is an unpaid obligation (liability).
• Treating deferred income as “extra income”:It is a liability for work still to be done.
• Treating accrued income as “future income”:It is current-period income that is unbilled/unreceived at year-end.
• Not separating tax from the expense (where relevant):Recoverable input tax is not part of the cost.
• Cut-off mistakes:For inventory, assess when control/ownership transfers (often evidenced by delivery terms). For revenue, use the point when the customer obtains the goods or services under the contract terms, not invoice date.
• Not updating figures after journals:Marks are often lost by calculating the adjustment correctly but leaving statements unadjusted.
• Dividends misclassification:A liability arises only when the distribution is authorised/approved and no longer at the entity’s discretion at the reporting date.

Summary

Timing adjustments ensure that financial statements reflect the correct period’s income and expenses. Accruals recognise unpaid expenses as liabilities so costs are not understated. Prepayments carry forward unconsumed costs as assets so expenses are not overstated. Accrued income recognises earned income not yet billed/received as an asset. Deferred income records unearned receipts as liabilities so income is not recognised too early. Alongside these, other period-end adjustments such as inventory cut-off, interest accruals, and receivables impairment ensure that profit and the statement of financial position are complete, realistic, and aligned with the period’s activity.

FAQ

What is the main purpose of timing adjustments?

To ensure profit reflects the period’s activity by recognising income when earned and expenses when incurred/consumed, rather than when cash moves.

How do accruals and prepayments affect profit?

Accruals increase expenses and reduce profit. Prepayments reduce expenses and increase profit (compared with charging the full amount in the current period).

Is deferred income “income” at the reporting date?

No. Deferred income is a liability representing goods/services still to be provided in future periods.

Where is accrued income shown in the statement of financial position?

It is shown as part of receivables (or separately described as accrued income) depending on the statement format used. The key point is that it represents income already earned but not yet invoiced/received at the reporting date.

Is the impairment allowance on receivables a timing adjustment?

It is primarily a valuation adjustment at period-end (an estimate of non-recoverable amounts), not a cut-off item based on timing of payment.

When do dividends become a liability?

Only when they have been authorised/approved so that the entity no longer has discretion to avoid the distribution at the reporting date.
