As Vietnam continues its economic integration on the global stage, the country’s accounting landscape is undergoing a significant transformation. The impending adoption of International Financial Reporting Standards (IFRS) alongside the existing Vietnam Accounting Standards (VAS) marks a pivotal shift in financial reporting practices for businesses operating in the country.
This guide explains the key differences between IFRS and VAS, the benefits of IFRS adoption, the challenges businesses may face during this transition and what applying both frameworks looks like in practice.
- IFRS is compulsory from FY2026 for state-owned enterprises, listed companies and large unlisted public companies, while FDI enterprises remain on a voluntary adoption track.
- Vietnamese Financial Reporting Standards, intended to narrow the gap between VAS and IFRS for entities not adopting IFRS directly, have not yet been issued.
- Most FDI enterprises maintain VAS statutory books locally while preparing a separate IFRS package for parent-company consolidation.
- Leases, revenue recognition, deferred tax and fixed-asset measurement are the areas most likely to require adjustment when converting VAS figures to IFRS.
- Successfully navigating the transition depends on regulatory readiness, system capability and staff training, areas where professional support can meaningfully reduce risk.
Overview of the standards
As cross-border investment grows, a common accounting language has become essential for comparing financial information across jurisdictions. International Financial Reporting Standards (IFRS), developed by the International Accounting Standards Board, are applied in more than 160 countries and are treated as the global standard, including by the World Bank, IMF and other international lenders.
In Vietnam, the Ministry of Finance sets Vietnam Accounting Standards (VAS), developed to suit the country’s economic conditions. Decision 345/QĐ-BTC approved a roadmap to bring Vietnam’s accounting framework closer to IFRS through the introduction of Vietnamese Financial Reporting Standards (VFRS).
Benefits of the IFRS
Adoption of the IFRS brings three main benefits:
- greater transparency and comparability of financial information for investors and regulators
- stronger accountability, since it gives capital providers the information needed to hold management to account
- improved economic efficiency, as a single trusted accounting language lowers the cost of capital and reduces international reporting costs
2026 IFRS roadmap in Vietnam
Vietnam Accounting Standards (VAS) include:
- 26 Vietnam Accounting Standards (VAS) issued by the Vietnam Ministry of Finance from 2001 to 2005
- Circular 99/2025/TT-BTC for corporate accounting
- Circular 202/2014/TT-BTC for consolidation
- Other applicable regulations by the MoF
Current VAS standards are primarily based on the old versions of IAS with certain customisations to fit Vietnam’s circumstances.
VAS is a rule-based, cost-oriented accounting regime designed primarily for statutory compliance. The core standards themselves have not changed since publication. Circular 99 and other implementing circulars update how they are applied in practice, not the standards themselves.
International Financial Reporting Standards (IFRS) include:
- IAS: 24 standards (released from 1973 to 2001)
- IFRS: 17 standards (released after 2001)
- Interpretations from SIC and IFRIC
IFRS follows a principles-based approach and is updated and revised more frequently than VAS.
IFRS adoption in Vietnam
Vietnam’s IFRS adoption follows a three-stage roadmap set out by the Ministry of Finance. The table below summarises what each stage involves and which enterprises it applies to.
| Vietnam IFRS roadmap (Decision No. 345/QD-BTC dated 16 March 2020 issued by the Vietnamese MoF) | |
|---|---|
| Stage 1: IFRS readiness preparation (from 2020 to 2021) | Publishing the Vietnamese translation of IFRS standards, training and building implementation guidelines |
| Stage 2: IFRS pilot implementation (from 2022 to 2025) | Voluntary adoption of consolidated financial statements by companies selected by the MoF (state-owned enterprises, listed companies, large-scale unlisted public companies). FDI companies may voluntarily adopt IFRS for separate financial statements. |
| Stage 3: IFRS compulsory implementation (after 2025) | Consolidated financial statements for state-owned enterprises, listed companies and large-scale unlisted public companies. FDI companies remain on a voluntary basis for separate financial statements. |
The challenge of converting from VAS to IFRS
The table below outlines the main challenges businesses typically encounter during this process.
| Challenge | Details |
|---|---|
| Acceptance by regulatory authorities | Tax authorities still expect detailed guidance before accepting IFRS-based positions, reflecting a rules-based mindset not yet aligned with IFRS’s principles-based approach. |
| Information system support | Existing systems are often not built to collect the additional data IFRS requires, and coordination between accounting and other departments needs strengthening. |
| Fair (market) value determination | Vietnam’s legal framework offers limited guidance on determining fair value, and many businesses remain accustomed to a cost model rather than a fair value model. |
| Staff skills | IFRS is more complex than VAS and requires a deeper understanding of business substance over form. |
| Language barrier | IFRS standards and technical materials are primarily written in English, requiring strong English proficiency among accounting staff. |
| Training needs | Businesses need dedicated accounting training programmes to build IFRS capability. |
IFRS vs VAS
Below is a brief explanation of the two standards.
Preparation of financial statements
1. Presentation of financial statements
| IAS 1 | VAS 21 |
|---|---|
A complete set of financial statements includes:
IAS 1 allows expenses to be presented on the face of a statement of profit or loss either by nature or by function. | A complete set of financial statements includes:
Changes in equity are disclosed in the notes on owners’ capital under VAS. Companies reporting under VAS are required to apply the standardised chart of accounts and financial statements format. VAS requires expenses to be presented by function on the face of the statement of profit or loss and to be disclosed by nature in the notes. |
2. Statement of cash flows
| IAS 7 | VAS 24 |
|---|---|
| Bank overdrafts are included in cash and cash equivalents. Disclosure of changes in financing-related liabilities must occur apart from changes in other assets and liabilities. Cash flows from hedging activities are classified as investment activities except when they are for trading purposes (which are classified as operating activities) or when a contract is accounted for as a hedge of an identifiable position. In this case, the cash flows of the contract are classified in the same manner as the cash flows of the position being hedged. | Under VAS 24 and Circular 99, bank overdrafts are generally presented as short-term financial liabilities, similar to bank loans, unless they are integral to cash management. |
3. Events after the reporting period
| IAS 10 | VAS 23 |
|---|---|
| Under IAS 10, an entity is obligated to adjust for profit sharing or bonus payments that are determined after the reporting period if there is a legal or constructive obligation to make such payments due to events occurring before that date. | Profit-sharing or bonus payments are adjusted only if there is a legal obligation established by the reporting date. Amounts approved or determined after the reporting period are generally treated as non-adjusting events. |
4. The effects of changes in foreign exchange rates
| IAS 21 | VAS 10 |
|---|---|
| IAS 21 differentiates between functional currency and presentation currency. IAS 21 provides general guidelines on the initial recognition of foreign currency transactions and subsequent measurement for items in foreign currency. | There is no requirement in VAS 10 to ascertain a functional currency. Enterprises determine an accounting currency based on prescribed criteria and administrative approval. In that case, there is no requirement to notify the tax office. Circular 99 provides updated guidance on exchange rates for foreign currency transactions and the conversion of financial statements prepared in a foreign accounting currency into Vietnamese Dong. |
5. Related party disclosures
| IAS 24 | VAS 26 |
|---|---|
| IAS 24 defines various classes of entities and people as related parties and sets out the disclosures required with respect to those parties. The concepts of control and significant influence are used to assess the relationship. IAS 24 states that the following are not related parties:
| VAS 26 is based on the previous version of IAS 24 (1994). Decree 132/2020/ND-CP supplements the definitions of related parties by using a threshold to assess the relationship:
Decree 132/2020/ND-CP states that the following are still considered related parties:
|
Revenue recognition
1. Revenue from contracts with customers
| IFRS 15 | VAS 14 & VAS 15 |
|---|---|
| IFRS 15 became effective on 1 January 2018, replacing both IAS 11 (Construction contracts) and IAS 18 (Revenue). IFRS 15 provides one comprehensive revenue recognition model for all customer contracts to improve comparability within industries, across industries and in capital markets. Revenue is recognised when control of a good or service transfers to a customer. IFRS 15 requires a five-step process to be applied before revenue can be recognised:
| VAS 14 and VAS 15 are based on the previous versions of IAS 18 and IAS 11, respectively. A number of the requirements under IFRS 15 have been included in VAS and Circular 99, such as allocating revenue to free goods sold in a bundle and deferring revenue to match subsequent free goods under loyalty programmes. Revenue is recognised when risks and rewards are transferred to the buyer. VAS 14 provides five conditions for recognising revenue from the sale of goods and four conditions for recognising revenue from the provision of services. VAS 15 provides guidance on recognising revenue from construction contracts. Additionally, Circular 99 provides detailed accounting guidance on revenue recognition for real estate and traditional customer programmes, considering variable consideration in construction contracts. |
Income taxes
| IAS 12 | VAS 17 |
|---|---|
IAS 12 requires an entity to recognise a deferred tax liability or (subject to specified conditions) a deferred tax asset for all temporary differences, with some exceptions as follows:
A deferred tax asset is recognised for deductible temporary differences, subject to the following conditions:
| VAS 17 is based on the previous version of IAS 12. Under VAS 17, deferred tax liability is recognised for all taxable temporary differences, except when arising from the initial recognition of an asset or liability in a transaction that does not affect profit. VAS 17 remains silent on temporary differences related to business combinations and goodwill. Circular 202 supplements and requires that a deferred tax liability is recognised for all taxable temporary differences unless the deferred tax liability arises from the initial recognition of an asset or a liability of a transaction that does not affect accounting profit or taxable profit (or tax loss) at the time of the transaction. VAS 17 also requires the recognition of deferred tax assets for all deductible temporary differences with exceptions similar to IAS 12, but is silent on temporary differences arising from a business combination. |
Fixed assets
1. Tangible fixed assets
| IAS 16 | VAS 03 |
|---|---|
| An item of property, plant and equipment (PPE) that qualifies for recognition as an asset shall be measured at its cost, without any minimum capitalisation threshold. IAS 16 allows two accounting models: the cost model and the revaluation model. (IAS 16.29 & 31). IAS 16 requires an entity to determine the depreciation charge separately for each part of a PPE item with a cost that is significant in relation to its total cost. Under IAS 16, the residual value and useful life are required to be reviewed at least at each financial year-end and, if there is any change, it will be accounted for as a change in accounting estimate. | The company can set a capitalisation threshold for a fixed asset at VND 30 million or more. Only the cost model is allowed under VAS 3. (VAS 3.13) VAS 3 does not require a separate depreciation charge for each significant part of PPE. VAS 3 requires the review of useful life but is silent on the review of residual value at year end. |
2. Intangible fixed assets
| IAS 38 | VAS 04 |
|---|---|
| IAS 38 requires intangible assets to be initially measured at cost. Entities can use either the cost or revaluation models after initial recognition. (IAS 38.72) The depreciable amount of an intangible asset with a finite useful life shall be allocated systematically over its useful life. IAS 38 does not impose any limit on the useful life. (IAS 38.97, IAS 38.88) IAS 38 requires an entity to perform an impairment test for intangible assets in accordance with IAS 36. (IAS 38.111, IAS 36.10) | VAS 4 requires two additional conditions for intangible asset recognition compared with IAS 38:
Under VAS 4, only the cost model is allowed, and the amortisation period is up to 20 years. (VAS 4.53, 4.54) VAS 04 does not provide a comprehensive impairment testing framework comparable to IAS 36; impairment losses are recognised only when there is evidence of a permanent decline in value. |
3. Investment property
| IAS 40 | VAS 05 |
|---|---|
| An investment property shall be measured initially at its cost. Transaction costs shall be included in the initial measurement. Subsequently, an entity shall choose either the fair value model or the cost model and shall apply it consistently to all of its investment property. (IAS 40.56) | VAS 5 only allows the cost model. Circular 99 provides additional guidance for investment properties held for capital appreciation. Investment properties held for capital gains are not depreciated but are subject to impairment assessment when there is evidence of a permanent decline in value. Impairment losses are recognised in profit or loss (commonly as cost of sales for real estate entities) when the loss is reliably measurable. However, the entity is not allowed to recognise unrealised gains arising from changes in market value. |
4. Impairment of assets
| IAS 36 | No equivalent VAS |
|---|---|
| IAS 36 – Impairment of Assets aims to ensure that an entity’s assets are carried at no more than their recoverable amount. All assets within the IAS 36 scope are tested for impairment where there is an impairment indicator. Impairment indicators include:
| In certain accounting guidance by the Ministry of Finance, the term impairment has been used, but there is a lack of clarity and application to determine impairment loss. Circular 99 requires investment properties held for capital appreciation not to be depreciated, but to be assessed for impairment when there is evidence of a permanent decline in value, without providing detailed guidance. |
5. Lease accounting
| IFRS 16 (replaced IAS 17 effective from 1 January 2019) | VAS 6 |
|---|---|
| IFRS 16 (replaced IAS 17 effective from 1 January 2019) defines a lease as a contract, or part of a contract, that conveys the right to use an asset (the underlying asset) for a period of time in exchange for consideration. Under IFRS 16, lessees have to recognise a lease liability IFRS 16 requires lessees to recognize a lease liability representing future lease payments and a ‘right-of-use asset’ for nearly all lease contracts. Lessees will report interest expenditure associated with the lease liabilities and right-of-use asset depreciation in the income statement. | Leases are required to be classified as either:
Finance lease assets are recorded as assets on the balance sheet and are depreciated accordingly, and depreciation expense is recorded in the statement of business activities. VAS 06 and Circular 99 do not adopt the IFRS 16 right-of-use model. |
Financial instruments and fair value
1. Fair value
| IFRS 13 | No equivalent VAS |
|---|---|
| IFRS introduces the concept of fair value, which is unfamiliar to companies complying with VAS. IFRS 13 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A fair value measurement requires management to determine four things:
IFRS 13 establishes a fair value hierarchy categorised into three levels to provide inputs to valuation techniques used to measure fair value. The hierarchy, from highest priority, is as follows:
| Accounting Law 88, issued in 2015, introduces the concept of fair value, with the instruction that the MoF will issue further specific guidance. No comprehensive guidance on fair value has been issued to date. Circular 99 provides limited and transaction-specific guidance on fair value measurement, without establishing a fair value hierarchy, valuation techniques or consistent measurement principles. In detail:
|
2. Financial instruments
| IFRS 9 | No equivalent VAS |
|---|---|
| IFRS 9 (replaced IAS 39) addresses the classification, measurement and derecognition of financial assets and financial liabilities. IAS 32 – Financial instruments: Presentation. IFRS 7 – Financial instruments: Disclosures IFRS 9 introduces a new model for recognising impairment losses – the expected credit losses (ECL) model. IFRS 9 has three classification categories for debt instruments:
| There is no VAS standard equivalent to IFRS 9, IAS 32 and IFRS 7. However, Circular 99 provides limited, rule-based guidance on the presentation and accounting of certain financial instruments, such as convertible bonds and treasury shares, but does not establish an integrated financial-instrument framework comparable to IFRS. VAS has not adopted the ECL model; instead, provisioning under the guidance of Circular 48/2019/TT-BTC is still applied. Investments in shares and debt instruments are classified by nature and purpose (e.g. trading investments, long-term investments, investments in subsidiaries, associates and joint ventures) rather than under an IFRS-style business-model assessment. These investments are generally carried at historical cost and are only written down when there is evidence of decline in value; fair-value remeasurement is not applied. |
Under IFRS 9, the expected credit losses (ECL) model is a three-stage approach based on the change in the credit quality of financial assets since initial recognition.
Please refer to the below structure:
| IFRS 9 | No equivalent VAS |
|---|---|
Hedge accounting: an entity is only allowed to apply hedge accounting if it meets the specified qualifying criteria as follows:
| Circular 48/2019/TT-BTC:
In addition, there is no guidance for hedge accounting in VAS. |
Business combinations
1. Separate financial statements
| IAS 27 | Guidance on corporate accounting system – Circular 99 |
|---|---|
| IAS 27 does not mandate which entities should produce separate financial statements. An entity might be required by local legislation, or it might elect, to present separate financial statements. If separate financial statements are prepared, IAS 27 should be followed. When an entity prepares its separate financial statements, investments in subsidiaries, associates and joint ventures are accounted for either:
| The preparation of separate financial statements is guided in Circular 99, whereas the preparation of consolidated financial statements is guided in Circular 202. Under Vietnamese regulations, entities prepare separate financial statements as the primary statutory financial statements. Consolidated financial statements are required only when control criteria are met. In separate financial statements, investments in subsidiaries, associates and joint ventures are accounted for using the cost method, being recorded at original cost (purchase price plus directly attributable expenses) and subsequently adjusted only for provisions for decline in value where applicable. |
2. Consolidated financial statements
| IFRS 10 | VAS 25 |
|---|---|
A parent entity is not required to present consolidated financial statements if it satisfies any of the following conditions:
Additionally, an entity that meets the definition of an investment entity under IFRS 10 can account for its subsidiaries at fair value through profit or loss as per IFRS 9 rather than presenting consolidated financial statements. | Consolidated financial statements are governed by VAS 25 and Circular 202/2014/TT-BTC. Consolidated financial statements are generally required when control exists. Exemptions from consolidation are limited and rule-based, and are not aligned with IFRS 10 exemption criteria. An entity may be exempt from preparing consolidated financial statements mainly when its parent entity prepares consolidated financial statements in accordance with VAS that include the reporting entity, subject to strict regulatory conditions. VAS 25 and Circular 202 do not recognise the concept of an investment entity, and therefore do not permit measurement of subsidiaries at fair value through profit or loss in lieu of consolidation. |
3. Non-current assets held for sale and discontinued operations
| IFRS 5 | No equivalent VAS |
|---|---|
| An entity shall classify a non-current asset (or disposal group) as held for sale if its carrying amount will be recovered principally through a sale transaction rather than through continuing use. In general, assets (or disposal groups) held for sale are not depreciated, are measured at the lower of carrying amount and fair value less costs to sell, and are presented separately in the statement of financial position. | No comprehensive guidance on non-current assets held for sale and discontinued operations has been issued to date. |
4. Business combinations
| IFRS 3 | VAS 11 |
|---|---|
| Under IFRS 3, goodwill is not amortised and is subject to an annual impairment review or, more frequently, if there is an indication of impairment. Non-controlling interest (NCI) is measured either at the NCI’s proportionate share of the recognised amounts of the acquiree’s identifiable net assets or at fair value. Under IFRS 3, contingent consideration is recognised at its fair value at the date of acquisition. The classification of contingent consideration as either a liability or equity is determined with reference to the guidance in IAS 32. | Under VAS 11, goodwill is recognised as an asset and amortised on a systematic basis over its expected useful life, not exceeding 10 years. Only the proportionate interest method is allowed under Circular 202. Under VAS 11, contingent consideration is included in the cost of a business combination at the acquisition date only when payment is probable and reliably measurable. Subsequent adjustments to contingent consideration are not remeasured at fair value, and are accounted for based on their substance, which may result in adjustments to the cost of combination, goodwill, or profit or loss. |
5. Investment in associates
| IAS 28 | VAS 7 & VAS 8 |
|---|---|
| IAS 28 (as amended in 2011) provides guidance on how to apply, with certain limited exceptions, the equity method to investments in associates and joint ventures. For separate financial statements, the accounting for investments in associates and joint ventures is governed by IAS 27. The equity method is required for accounting for an investment in an associate or a joint venture, except in the following circumstances:
| Similarly, VAS 8 is derived from the earlier version of IAS 31 (revised in 2003), detailing the accounting treatment for interests in various types of joint ventures, including jointly controlled operations, assets and entities. These can also be accounted for using either the equity method or the cost method. VAS 7 and VAS 8 govern the accounting for investments in associates and joint ventures under Vietnamese Accounting Standards. In separate financial statements, such investments are accounted for using the cost method only. In consolidated financial statements, investments in associates and joint ventures are generally accounted for using the equity method, with limited exceptions where cost may be applied due to long-term restrictions. |
Others
1. Employee benefits
| IAS 19 | No equivalent VAS |
|---|---|
| Short-term benefits: recognised at the undiscounted amount expected to be paid in exchange for services rendered by an employee during an accounting period. Post-employment benefits: classified as either defined contribution plans or defined benefit plans, depending on the economic substance of the plan. Termination benefits: recognised as a liability and expense at the earlier of when the entity can no longer withdraw the offer of those benefits and when the entity recognises restructuring costs within the scope of IAS 37 that involve the payment of those benefits. | VAS does not contain a standard equivalent to IAS 19. Employee benefits are accounted for primarily under Circular 99 on a cost-incurred basis, including wages, salaries and statutory contributions to social insurance. Termination benefits are recognised in accordance with the Labour Law when payment obligations arise. |
2. Share-based payment
| IFRS 2 | No equivalent VAS |
|---|---|
A share-based payment transaction is defined as one in which the entity:
In such transactions, the entity either:
| No comprehensive guidance on share-based payment has been issued to date. |
3. Borrowing costs
| IAS 23 | VAS 16 |
|---|---|
Defines borrowing costs as interest and other expenses an entity incurs in relation to the borrowing of funds. These costs can include:
| VAS 16 is modelled after an earlier version of IAS 23.
|
Practical implementation
Applying VAS and IFRS raises two recurring questions: how to manage reporting across both frameworks, and which adjustments come up most often during conversion.
Dual-reporting requirements for FDI enterprises
VAS statutory reporting remains mandatory for foreign-owned enterprises. IFRS stays voluntary unless the entity is a state-owned enterprise, listed company or large unlisted public company. Most FDI enterprises keep VAS statutory books locally and prepare a separate IFRS package for parent consolidation, either through conversion workpapers or a parallel IFRS ledger reconciled to VAS. Vietnamese Financial Reporting Standards, meant to narrow this gap, have not yet been issued.
Common conversion adjustments in practice
Recurring adjustments include:
- Recognising right-of-use assets and lease liabilities under IFRS 16, where VAS 6 leaves most leases off-balance-sheet.
- Shifting revenue timing under IFRS 15’s five-step model versus VAS’s risk-and-reward basis.
- Recognising deferred tax on business combinations, which VAS 17 does not address.
- Reassessing PPE where the group applies the IAS 16 revaluation model, since VAS 3 permits only cost.
Conclusion
IFRS remains the most widely accepted global accounting language, and as Vietnam continues to attract FDI, understanding both frameworks is increasingly essential. IFRS is compulsory from FY2026 for state-owned enterprises, listed companies and large unlisted public companies, while FDI enterprises remain on a voluntary track pending the introduction of VFRS. For businesses within scope, or considering voluntary adoption, the shift brings greater transparency, improved comparability for M&A and group reporting, and closer alignment between Vietnamese and international capital markets.
The main challenges are readiness, resourcing and access to the right information, most addressed through training, with the rest benefiting from professional support. Businesses converting from VAS to IFRS should engage professionals with expertise in both frameworks to manage the transition effectively.
