Goodwill on a balance sheet is the part of an acquisition price that cannot be pinned to any identifiable asset or liability: what the buyer paid, minus the fair value of the net identifiable assets it received. It sits in non-current assets as an intangible, it only ever arises from buying a business, and after day one it is either tested for impairment (IFRS, and US GAAP for public companies) or amortised (an election open to US private companies and not-for-profits).
Goodwill only exists because someone bought a business
When you acquire a company, you record every identifiable asset and liability you take on at its fair value on the acquisition date. That includes the obvious items, such as receivables, inventory and equipment, and also intangibles that never appeared on the seller's own books: brand names, customer relationships, software, order backlogs. Whatever the price exceeds that net figure by is goodwill.
That residual pays for things that cannot be separated and sold on their own: an assembled team, expected synergies, a market position, a reputation. You cannot record goodwill you build yourself. A business that spends ten years earning customer loyalty does not get to put that loyalty on its own balance sheet; only a buyer who pays for it can.
- Goodwill = consideration paid − (fair value of identifiable assets − fair value of liabilities assumed)
If you buy less than 100% of the target, the calculation also brings in the non-controlling interest. The example below keeps to a full acquisition so the mechanics stay visible.
Worked example: a coffee roaster buys a café chain
Harbourline Roasters buys 100% of Kiln Street Cafés, a group of four cafés, for $2,000,000 cash on 1 January. Its advisers value what came across:
- Cash and receivables — $180,000
- Inventory — $70,000
- Fit-outs and equipment — $950,000
- Kiln Street brand name — $250,000
- Customer relationships (a wholesale contract with a hotel group) — $150,000
- Total identifiable assets — $1,600,000
- Trade payables — $120,000
- Bank loan — $280,000
- Total liabilities assumed — $400,000
Net identifiable assets are $1,600,000 − $400,000 = $1,200,000. Goodwill is $2,000,000 − $1,200,000 = $800,000.
The acquisition entry in Harbourline's books:
- Dr Cash and receivables $180,000
- Dr Inventory $70,000
- Dr Equipment and fit-outs $950,000
- Dr Brand (intangible) $250,000
- Dr Customer relationships (intangible) $150,000
- Dr Goodwill $800,000
- Cr Trade payables $120,000
- Cr Bank loan $280,000
- Cr Cash $2,000,000
Debits and credits both total $2,400,000. Notice that the brand and the hotel contract are recorded separately from goodwill. If the valuation had skipped them, goodwill would have been $1,200,000 and the balance sheet would hide two assets that have their own useful lives.
What happens to goodwill after the deal: three regimes
US GAAP, public companies (ASC 350): impairment only
Goodwill is not amortised. It is assigned to reporting units and tested for impairment at least once a year, and sooner if something suggests the unit has lost value, such as losing a major customer or a sustained fall in results. Since ASU 2017-04 removed the old second step, the test is a single comparison: if a reporting unit's carrying amount, including its goodwill, exceeds its fair value, the excess is the impairment loss, capped at the goodwill balance.
Suppose that in year three a new competitor opens beside two of the cafés. Kiln Street, as a reporting unit, has a carrying amount of $3,050,000 including the $800,000 of goodwill, and its fair value comes out at $2,780,000. The impairment is $3,050,000 − $2,780,000 = $270,000:
- Dr Goodwill impairment loss $270,000
- Cr Goodwill $270,000
Goodwill drops to $530,000 and the loss goes through profit or loss. Under US GAAP a goodwill impairment is not reversed later, even if the cafés recover.
US GAAP private-company alternative: amortise over up to ten years
Since ASU 2014-02, a private company can elect to amortise goodwill on a straight-line basis over ten years, or a shorter period if it can show a shorter useful life is more appropriate. It then tests for impairment only when a triggering event occurs, rather than every year. ASU 2021-03 added a further option for private companies and not-for-profits: assess whether a triggering event has occurred only at reporting dates rather than continuously.
If Harbourline were private and made the election, it would book $800,000 ÷ 10 = $80,000 a year:
- Dr Goodwill amortisation expense $80,000
- Cr Accumulated amortisation — goodwill $80,000
After three years goodwill would be carried at $560,000 before any impairment. One caution: these alternatives are not available to public business entities, so a company that later lists or merges with a SPAC can find itself having to unwind them retrospectively.
IFRS (IAS 36): annual test at the cash-generating-unit level
Under IFRS, goodwill is never amortised. It is allocated to the cash-generating units (CGUs) expected to benefit from the acquisition and tested every year whether or not there is any sign of trouble. The CGU's carrying amount is compared with its recoverable amount, which is the higher of:
- Fair value less costs of disposal — what a market participant would pay for the unit, net of selling costs.
- Value in use — the present value of the cash flows the unit is expected to generate in its current condition.
Take the same year-three facts. The Kiln Street CGU carries $3,050,000; its fair value less costs of disposal is $2,700,000 and its value in use is $2,840,000. Recoverable amount is the higher figure, $2,840,000, so the impairment is $210,000. The loss is applied to goodwill first, and any excess beyond goodwill would then reduce the unit's other assets pro rata. IAS 36 states plainly that an impairment loss for goodwill is never reversed.
The same café group therefore produces a $270,000 charge under US GAAP and a $210,000 charge under IFRS, because value in use, a measure specific to the owner, can exceed market fair value.
A note on IFRS for SMEs and on future changes
Entities reporting under the IFRS for SMEs Standard amortise goodwill instead. Where its useful life cannot be estimated reliably, management uses its best estimate, which may not exceed ten years. The IASB has looked at bringing amortisation back for full IFRS and, in 2022, tentatively decided to keep the impairment-only model; its 2024 exposure draft on business combinations focused on disclosures and refinements to the impairment test.
Negative goodwill: when the buyer gets a bargain
Occasionally the fair value of the net identifiable assets exceeds the price, typically in a forced sale. Both IFRS 3 and ASC 805 require the buyer to recheck that every asset, liability and the consideration have been identified and measured correctly. Any excess that survives that review is recognised immediately as a bargain purchase gain in profit or loss. It is never shown as negative goodwill on the balance sheet.
How to read goodwill on someone else's balance sheet
- Compare it with equity. A goodwill balance close to or above total equity tells you most of the net worth rests on past acquisition prices, not on assets you could sell.
- Calculate tangible net worth. Equity minus goodwill and other intangibles. Many lenders write covenants on this figure precisely because goodwill cannot be sold separately.
- Read impairment as a signal, not a cash cost. An impairment uses no cash in the year it is booked, but it is the accounts admitting that an earlier price was too high for the results that followed.
- Check the notes. The notes show goodwill by segment or unit and the key assumptions behind the latest test, which tells you which acquisition is under pressure.
Common mistakes
- Recording goodwill you created. Internally generated goodwill is never capitalised, however valuable the brand feels.
- Dumping identifiable intangibles into goodwill. Customer lists, brands, licences and software belong in their own accounts with their own lives.
- Testing at the wrong level. Goodwill must be allocated to reporting units (US GAAP) or CGUs (IFRS) at acquisition; testing the whole group can hide a failing unit behind a healthy one.
- Ignoring triggering events between annual tests. A lost contract in month four does not wait for the year-end test.
- Electing the private-company alternative with an IPO on the horizon. Unwinding years of amortisation is expensive.
- Writing impairment back up. Neither framework allows it for goodwill.

HelloBooks will not value a business for you; that is work for your valuer and your accountant. What it does is keep the resulting entries organised and reviewable. You can add dedicated accounts for goodwill, each acquired intangible, accumulated amortisation and impairment losses to your customisable chart of accounts. The acquisition entry, annual amortisation and any impairment are posted as journal entries that go through approval, with reversal available if a draft was wrong and a full audit trail of who posted what.
If the acquired business keeps its own books, multi-entity accounting with consolidation lets you run it as a separate entity and roll it up at group level. Tracking by class or location gives you a P&L for the acquired unit, and budget-versus-actual reporting shows early when results are drifting below the plan that justified the price, which is exactly the kind of evidence an impairment review starts from. Period locking stops anyone changing a tested year after the accounts are signed off.
