2.4 Deferred Revenue & Unearned Income

A deferral of revenue (also called unearned revenue, deferred income, or a contract liability) happens when cash arrives before the company has earned it. Gift cards, legal retainers, prepaid bookkeeping packages, magazine subscriptions, customer deposits, and progress billings collected in advance all fit. The customer has a claim on future work; that claim is a liability, not income.

Two entries exist, and mixing them is the unit's most expensive mistake.

1. Original receipt (source document — uses Cash):

This is not an adjusting entry. Adjusting entries at month-end, quarter-end, or year-end still follow the Cash prohibition. The debit to Cash belongs to the day the money hit the bank, just like recording a sale on account belongs to the invoice date.

2. Adjusting entry (cutoff — does not use Cash):

Assets do not move at cutoff. The liability shrinks and equity rises through revenue. That is the earning event the time-period assumption was waiting for.

If the bookkeeper credited Service Revenue on the day cash arrived, there is nothing left in Unearned Revenue to adjust — and the financial statements already show income that has not been earned. Fixing that is an error-correction problem. Preventing it is this section.

Worked example: three-month bookkeeping retainer

On January 1, 2026, a client prepays $6,000 for January, February, and March bookkeeping (equal monthly service).

January 1 original entry

January 1 revenue from this contract is $0. You have cash and a $6,000 obligation.

January 31 adjusting entry — one month earned: $6,000 / 3 = $2,000

T-accounts after January 31:

Unearned balance = $4,000 (February and March still owed). Repeat $2,000 on February 28 and March 31. After March 31 the liability is zero and $6,000 of revenue has been recognized $2,000 per month, which matches performance.

The chart later in this section plots that remaining liability. It should stair-step down by $2,000 each month-end, not collapse to zero on January 1.

Worked example: gift cards

On December 20, 2026, Piedmont sells $1,500 of gift cards for cash.

December 20 sales revenue from the cards is $0. Selling a gift card is borrowing purchasing power from the customer. During January, customers redeem $420 of cards for merchandise (ignore sales tax and inventory here; the revenue cutoff is the point).

January 31 unearned balance = $1,500 − $420 = $1,080, still a liability. Do not take the leftover $1,080 to January revenue because "they might not come back." Unused-card breakage is an estimate topic; until you have a supportable breakage policy, the conservative bookkeeping treatment that CB-style items test is: liability until redeemed. Crediting Sales $1,500 on December 20 would overstate December income and hide a $1,500 obligation.

Worked example: prepaid project, percent complete

A client pays $12,000 on February 1 for a project that will take several months. Piedmont records Debit Cash $12,000; credit Unearned Project Revenue $12,000. At February 28 the job is 25 percent complete and that estimate is supportable from labor hours.

Amount earned in February: 0.25 × $12,000 = $3,000

Remaining unearned = $9,000. If instead you credited Project Revenue $12,000 on February 1, February income includes $9,000 of work you have not done. That is cash-basis thinking wearing an accrual disguise.

Partial months

Not every retainer starts on the first. Suppose $4,800 arrives on January 16 for four months of service beginning that day. A clean monthly rate is $1,200. At January 31 you have 15 days of a 31-day January:

15/31 × $1,200 ≈ $581 (rounded to the nearest dollar: 15/31 × 1,200 = 580.65, typically $581)

Some shops use a 30-day month: 15/30 × $1,200 = $600. The exam item will either give the day-count convention or use dates that divide evenly. What does not change is the pattern: original Debit Cash $4,800; credit Unearned $4,800, then adjust only the earned slice. Taking $1,200 on January 31 for a half-consumed January would overstate January revenue by about $600.

Reversing entries and deferrals

Accruals are often reversed because the next cash event is a full invoice or a full payroll check. Unearned balances are usually not reversed. After January 31, $4,000 of the retainer is still unearned. If you reversed the $2,000 January earning (Debit Bookkeeping Revenue $2,000; credit Unearned $2,000), you would put earned January work back into the liability and then have to re-earn it. That extra loop is pointless unless software reverses every adjusting entry automatically — in which case you re-post the same $2,000 earning in February before adding February's $2,000. Unless a problem says the firm reverses deferrals, leave the remaining unearned balance alone and only record newly earned amounts.

Traps specific to deferred revenue

• Crediting revenue when the retainer check is deposited. That is the cash-basis error. Credit Unearned Revenue instead.
• Putting Cash on the January 31 adjusting entry. Cash already moved on January 1. The adjustment only reclassifies the liability to revenue.
• Adjusting the full leftover balance into revenue because you want the liability off the balance sheet. Earn it as you perform.
• Treating a prepayment as accrued revenue. Accrued revenue is earning without cash. Deferred revenue is cash without earning. They are opposite arrows on the decision tree.
• Debiting Accounts Receivable when the customer already paid. Receivable plus cash for the same fee double-counts assets.
• Forgetting gift cards at year-end. Outstanding cards are still unearned. Count the unredeemed subledger the way you count unbilled time.

Side-by-side with the other three families

AIPB's Mastering Adjusting Entries material is built around computing those end-of-period amounts, posting them, and landing on an adjusted trial balance that converts to the statements. This Independent OpenExamPrep chapter stays on the accrual and deferral revenue/expense entries. Prepaids, estimates, and the worksheet that carries the unadjusted trial balance to the statements are the next chapter.

If you remember only one sentence for Section 2.4: cash in is a liability until you earn it; the adjusting entry never restates the cash.
