Writing off assets without creating an audit problem
An asset write off policy exists to stop two things: assets disappearing without approval, and assets sitting on the register years after they were scrapped. A write-off removes an asset from the books because it no longer exists or has no remaining benefit. Done properly it is routine housekeeping. Done casually it is one of the easiest findings for an auditor to raise and one of the hardest for management to answer.

The asset write off policy: the short version
- Write-off, disposal and impairment are different things with different documentation.
- Never write off during a count. Open a search window of two to four weeks first.
- Approval should escalate with value, and suspected theft needs an incident record.
- Mark as written off, never delete. Deleting destroys the trail and frees the number.
- Rising loss write-offs are an upstream problem: custody, movements, exits or verification gaps.
Write-off, disposal and impairment are three different things
They get used interchangeably and they have different meanings, which matters because the documentation differs.
Disposal is the asset leaving the organisation: sold, traded in, donated or scrapped. There is usually a recipient and often proceeds.
Write-off is removing the carrying amount because the asset no longer exists or has no remaining benefit. Typically loss, theft, destruction, or an item that cannot be found after search.
Impairment is reducing the carrying amount of an asset that still exists and is still in use, because it is worth less than the books say.
The sequence that protects you
1. Verification identifies the asset as not found. Not a write-off yet. A finding.
2. A search window opens. Two to four weeks, with the department, the custodian and any obvious secondary locations checked, including suppliers holding equipment for repair.
3. What remains is documented. Asset number, description, cost, net book value, last known location and custodian, when it was last verified, and what search was carried out.
4. Authorisation. At the level your policy requires, which should escalate with value.
5. Accounting entry and register update. Both, on the same date, with the authorisation referenced.
Skipping straight from step one to step five is what produces the finding. It is also how organisations write off assets that were physically present in a different room.
What the authorisation should depend on
| Situation | Typical approval level | Extra evidence |
|---|---|---|
| Low value, fully depreciated, obsolete | Register owner or department head | Condition record |
| Material net book value remaining | Finance director or equivalent | Reason, search record, valuation |
| Suspected theft | Senior management, and per policy the board or council | Incident report, and a police report where applicable |
| Destroyed by fire or flood | Senior management | Incident record and any insurance claim reference |
| Donor-funded asset | As above, plus funder notification | Grant terms checked before, not after |
The three findings auditors raise most often
Write-offs with no supporting authorisation. The entry exists, the approval does not. This is the most common and the easiest to prevent.
Write-offs concentrated just before year end. A cluster of removals in the final weeks invites the question of whether the register was being tidied to match rather than corrected to reflect.
Assets written off that are still in use. Discovered when a subsequent verification finds an asset with no record. It usually means a not-found asset was written off without a search, and the asset was in the next building.

Write-off does not mean delete
The record stays. Mark it as written off with the date, reason and authorisation, and remove it from the active register.
Deleting is wrong for three reasons. The audit trail disappears, so nobody can later explain what happened. The asset number becomes available for reuse, which corrupts history. And if the asset reappears, and they do, there is nothing to reinstate.
Preventing the write-off in the first place
Most write-offs for loss are a symptom of one of four upstream failures, and all four are cheaper to fix than to absorb.
- No custodian. Nobody would notice, so nobody reported it.
- Movements not recorded. The asset is where it was moved to, and the register is looking in the wrong place.
- Exit process with no asset step. The most common single cause of laptops leaving permanently.
- Verification too infrequent. A three year gap means the trail is cold on everything.
If write-offs for loss are rising year on year, the answer is upstream. Tightening the write-off approval process only makes the paperwork slower; it does not stop the losses.
Common questions about asset write off policy
How long should the search window be?
Two to four weeks is normal. Long enough for departments to respond and for equipment out at suppliers to be identified, short enough that the report is still current.
What if a written-off asset turns up later?
Reinstate it with a note explaining what happened. This is why records are marked rather than deleted, and it is a good deal more common than people expect.
Do we need a police report for theft?
For material items, and for any insurance claim, generally yes. Follow your policy and your insurer’s requirements; the register records the reference either way.
Can fully depreciated assets be written off automatically?
No. A net book value of zero says the cost has been allocated, not that the asset has ceased to exist. Many fully depreciated assets are still in daily use and must stay in the register.
Who approves write-offs in a public body?
Public sector organisations usually have prescribed thresholds and committees. Follow the applicable regulations rather than an internal convention.
What about donor-funded assets?
Check grant terms before writing off. Funder conditions on disposal and loss frequently outlast the project and may require notification or approval.
Whatever your asset write off policy says about approval, insist on physical evidence of disposal. A signed form with no photograph, weighbridge ticket or certificate is the weakest document in an audit file.
