A fixed asset register is a detailed record of property, plant and equipment. IAS 16 does not prescribe a specific register format, but reliable asset-level records support recognition, depreciation, revaluation, impairment, disposal and disclosure.
The register should reconcile to the general ledger and physical assets. It is both an accounting record and an operational control.
Essential register fields
| Field | Purpose | Example |
|---|---|---|
| Asset ID | Unique tracking reference | MACH-00421 |
| Description and location | Identify and find the asset | CNC machine, Factory 2 |
| Acquisition and available-for-use dates | Recognition and depreciation timing | 15 March / 1 April |
| Cost components | Support carrying amount | Price, installation and testing |
| Useful life and residual value | Calculate depreciation | 10 years, 5,000 CU |
| Depreciation method | Pattern of consumption | Straight-line |
| Accumulated depreciation and impairment | Calculate net carrying amount | Updated each close |
| Disposal data | Remove asset accurately | Date, proceeds and buyer |
Recognition information
Record when the asset is controlled, its cost and when it becomes available for use. Capital projects may accumulate costs in construction in progress until ready.
Do not begin depreciation merely when cash is paid if the asset is not yet available for use.
Cost components
IAS 16 cost includes purchase price, directly attributable costs and qualifying dismantling or restoration estimates. Trade discounts and rebates reduce cost.
General administration, abnormal waste and many start-up costs are expensed.
Component accounting
Significant parts with different useful lives are depreciated separately. A building may have separate structural, roof, lift and air-conditioning components.
The register should link components to the parent asset while preserving independent depreciation.
Depreciation fields
Store method, useful life, residual value, accumulated depreciation and last calculation date. Review useful life and residual value at least at each year end.
See the IAS 16 depreciation guide.
Revaluation records
For revalued classes, retain valuation date, valuer, fair value, method, assumptions, revaluation surplus and accumulated depreciation treatment.
Review the fixed asset revaluation guide.
Impairment information
Link assets to cash-generating units and record indicators, recoverable amount tests, impairment losses and reversals.
A register does not replace IAS 36 analysis but provides the asset data needed for testing.
Physical verification
Periodically inspect assets and compare serial numbers, locations, custodians and condition with the register. Investigate missing, idle, damaged or unrecorded assets.
Use risk-based frequency for portable, valuable and theft-prone items.
Asset tagging
Barcode, QR, RFID or durable labels can improve verification. The tag should link to the system asset ID, not reveal sensitive values unnecessarily.
Control tag creation, replacement and retirement.
General ledger reconciliation
Reconcile register totals by asset class to general-ledger cost, accumulated depreciation, impairment and revaluation balances.
Differences may arise from manual journals, interface failures, timing or incorrect asset classes.
Addition controls
- approved capital expenditure request;
- purchase invoice and receipt evidence;
- capital versus expense review;
- available-for-use confirmation;
- asset class, location and custodian assignment;
- useful life and residual value approval.
Transfer controls
Record movements between locations, departments and custodians without changing total cost. Transfers may affect depreciation responsibility, insurance and impairment assessment.
Disposal controls
Authorise sale, scrapping or loss; update depreciation to disposal date; remove cost and accumulated depreciation; record proceeds and gain or loss.
Use the fixed asset disposal entries guide.
Assets under construction
Track project costs separately and transfer them to the correct asset class when available for use. Review stalled projects for impairment and costs that should be expensed.
Fully depreciated assets
Fully depreciated assets still in use remain in the register until disposal. Their continued use may indicate useful-life estimates should be reviewed for similar assets.
Leased and controlled assets
Keep lease right-of-use assets and owned property clearly identified. Operational registers can also track assets controlled but legally owned by another party.
Insurance and security data
The register can store insured value, policy reference, security interest and replacement cost for operational use. These values should be clearly distinguished from accounting carrying amount and fair value.
Maintenance integration
Link maintenance history, warranty expiry, inspection dates and downtime to the asset ID. Maintenance data can identify impairment indicators and support useful-life reviews.
Capital expenditure versus repairs
Use the register workflow to review whether expenditure creates future economic benefits or merely maintains current performance. Qualifying replacements are capitalised and the carrying amount of replaced components is derecognised.
Data migration and system changes
When moving to a new asset system, reconcile opening cost, depreciation, impairment and location data before go-live. Preserve original acquisition evidence and audit trails.
Disclosure support
The register supports IAS 16 reconciliations for additions, disposals, depreciation, impairment, revaluation and exchange effects by class.
Review frequency and ownership
Assign an owner for every asset class and set a review calendar for physical verification, useful lives, impairment indicators, insurance and inactive projects. High-risk portable assets may need more frequent checks than buildings.
Common mistakes
- using the general ledger as the only asset record;
- starting depreciation on invoice date automatically;
- failing to separate significant components;
- not reconciling physical assets;
- leaving disposed assets on the register;
- capitalising unsupported costs;
- ignoring fully depreciated assets still in use.

Key takeaway
A strong fixed asset register connects physical assets, accounting values and controls. Maintain asset-level evidence, reconcile every class and update additions, transfers and disposals promptly.
