IAS 16 Revaluation — Core Rule
Under IAS 16 Revaluation Model Accounting, property, plant and equipment is carried at its revalued amount — fair value at the date of revaluation less any subsequent accumulated depreciation and impairment losses — with gains recognised in Other Comprehensive Income (OCI) and losses generally recognised in profit or loss.
How IAS 16 Revaluation Works
- Election and frequency (IAS 16.29, 16.31): The revaluation model is an accounting policy choice applied to an entire class of PPE (e.g., all land and buildings), not cherry-picked assets. Revaluations must be sufficiently regular so that the carrying amount does not differ materially from fair value at the reporting date — in practice, every 3–5 years for stable assets, annually for volatile ones.
- Upward revaluations (IAS 16.39): An increase in carrying amount is credited to a revaluation surplus within equity (OCI), except to the extent it reverses a previous revaluation decrease on the same asset that was recognised in profit or loss — that portion is credited to profit or loss first.
- Downward revaluations (IAS 16.40): A decrease is charged to profit or loss, except to the extent a revaluation surplus exists for that same asset — that portion is debited against the surplus in OCI/equity.
- Depreciation after revaluation (IAS 16.50): Depreciation is calculated on the revalued carrying amount over the remaining useful life. The excess depreciation (revalued depreciation minus historical-cost depreciation) is an optional transfer from revaluation surplus to retained earnings — this is a direct reserves transfer, not through profit or loss (IAS 16.41).
- Deferred tax (IAS 12.20): A revaluation surplus creates a taxable temporary difference. Deferred tax liability must be recognised immediately against OCI (not profit or loss), so the net revaluation surplus in equity is presented after deferred tax.
- Disclosure (IAS 16.77): Entities must disclose the effective date of revaluation, whether an independent valuer was involved, the valuation methods and significant assumptions, the carrying amount under the cost model (if the revaluation model is used), and the revaluation surplus movement.
IAS 16 Revaluation — Practical Example
Scenario: A building is acquired on 1 Jan 20X1 for €5,000,000, useful life 40 years (straight-line, no residual value). At 31 Dec 20X3 (after 3 years' depreciation), it is revalued to €5,400,000. Tax rate: 25%.
Carrying amount before revaluation:
- Cost: €5,000,000
- Accumulated depreciation: €375,000 (€125,000 × 3)
- Net book value: €4,625,000
Revaluation uplift: €5,400,000 − €4,625,000 = €775,000Deferred tax on surplus: €775,000 × 25% = €193,750Net surplus to equity: €581,250Journal entry at revaluation date
| Account | Dr (€) | Cr (€) |
|---|
| Accumulated Depreciation | 375,000 | |
| Building (gross) | 400,000 | |
| Deferred Tax Liability | | 193,750 |
| Revaluation Surplus (OCI/Equity) | | 581,250 |
(Gross-up method: depreciation eliminated, gross asset restated to €5,400,000)
Annual depreciation going forward: €5,400,000 ÷ 37 remaining years = €145,946/year (vs. €125,000 historical cost). The incremental €20,946 can be transferred from revaluation surplus to retained earnings annually — a reserves transfer only, no P&L impact.
IAS 16 Revaluation — Common Pitfalls
- Applying the model to individual assets, not the full class: Selectively revaluing only appreciated assets within a class violates IAS 16.36, which requires the entire class to be revalued simultaneously (or on a rolling basis completed within a short period). Auditors will flag this as a cherry-picking policy.
- Misrouting the deferred tax: Some preparers recognise the deferred tax on revaluation through profit or loss. Per IAS 12.61A, the tax on items recognised in OCI must itself go through OCI — a frequent error in exam and in practice that distorts both the tax charge and equity.
- Forgetting to reverse the surplus on disposal: On disposal of a revalued asset, any remaining revaluation surplus for that asset is transferred directly to retained earnings (IAS 16.41). It is not recycled through profit or loss. Failing to do this overstates the revaluation surplus balance and understates retained earnings.
IAS 16 Revaluation — Key Paragraphs
- IAS 16.29 — permits the revaluation model as an alternative to the cost model; policy must apply to the whole class.
- IAS 16.39 — treatment of revaluation increases; credit to revaluation surplus in OCI.
- IAS 16.40 — treatment of revaluation decreases; charge to P&L except to extent of existing surplus.
- IAS 16.41 — transfer of surplus to retained earnings on depreciation or disposal; not through P&L.
- IAS 16.31 — frequency of revaluations; materiality threshold relative to fair value.
- IAS 12.61A — deferred tax on revaluation must be recognised in OCI, matching the underlying item.
