IFRS consolidated accounts: why adopt international standards in 2026?

Updated April 2026 - IFRS (International Financial Reporting Standards) are no longer reserved for listed groups. In 2026, the adoption of IFRS standards for consolidated accounts addresses strategic challenges that go well beyond mere compliance: international comparability, access to financing, investor credibility and the structuring of financial management.

The regulatory landscape has just taken a major step forward. The European Union officially adopted IFRS 18 Presentation and Disclosure in Financial Statements on 13 February 2026 (Regulation EU 2026/338, published in the Official Journal on 16 February 2026). This standard, which enters into force on 1 January 2027, requires a complete restructuring of the income statement with new mandatory subtotals and enhanced transparency on performance measures. Retrospective application means that 2026 data will need to be restated according to these new requirements. ESMA published a public statement on 17 February 2026 to guide implementation.

At the same time, the IASB published the March 2026 edition of the IFRS for SMEs Accounting Standard, updating the framework designed for small and medium-sized entities. Over 140 jurisdictions worldwide now require or permit IFRS, making it the most widely used accounting language on the planet.

Consolidated accounts present the financial position of a group of companies as if it were a single economic entity. They eliminate internal transactions (cross-sales, inter-company loans, reciprocal dividends) to give a true and fair view of the consolidated entity's assets, financial position and results.

IFRS standards impose a precise methodological framework for this consolidation:

• ▸IFRS 10 sets out the principles for the presentation and preparation of consolidated financial statements, based on the concept of control;
• ▸IFRS 3 governs business combinations and the treatment of goodwill;
• ▸IFRS 11 distinguishes joint ventures from joint operations;
• ▸IAS 28 regulates the equity method for associates;
• ▸IFRS 16 requires the capitalisation of virtually all lease contracts on the balance sheet.

In France, unlisted groups may voluntarily choose to apply IFRS for their consolidated accounts, subject to an irrevocable option exercised on a year-by-year basis for the entire consolidation scope (ANC regulation n° 2020-01).

Immediate international comparability

IFRS standards are the de facto standard for any group that maintains relationships with international stakeholders. Whether dealing with foreign investment funds, international banks or commercial partners operating across multiple countries, IFRS-prepared financial statements are immediately readable and comparable.

This comparability goes beyond a simple accounting translation exercise. It enables investors to benchmark the group's performance against international competitors, banks to assess credit risk on a homogeneous basis, and management to compare subsidiaries using common rules.

Broader access to financing

2025-2026 data confirms a structural trend: private equity funds, infrastructure investors and international banks overwhelmingly require or prefer IFRS presentation of financial statements. For a group considering a fundraising round, an IPO or a large-scale bank refinancing, the absence of IFRS accounts is a real handicap.

Consolidated accounts prepared under international standards reduce due diligence costs, accelerate verification processes and limit requests for restatements from financial analysts.

Stronger reporting discipline

Adopting IFRS imposes a methodological rigour that benefits the entire finance function. Requirements around fair value (IFRS 13), impairment testing (IAS 36), segment reporting (IFRS 8) and financial instruments (IFRS 9) oblige teams to structure their data collection processes, closing reviews and documentation.

This discipline translates concretely into better financial data governance, fewer consolidation errors and an enhanced ability to respond to information requests from statutory auditors and market authorities.

Preparation for regulatory changes

With the EU's adoption of IFRS 18 in February 2026 and its entry into force on 1 January 2027, groups already using IFRS have a considerable head start. Retrospective application requires restating 2026 data, which demands several months of advance preparation. Groups already familiar with the IFRS framework can integrate these changes into their existing closing cycle, while those discovering IFRS for the first time will need to manage both the initial transition and the new IFRS 18 requirements simultaneously.

Multiple documented accounting judgements

Unlike the French general chart of accounts, which relies largely on precise rules, IFRS standards give a central role to professional judgement. Determining fair value, identifying cash-generating units for impairment tests, assessing effective control or estimating expected credit losses all require documented, defensible and auditable analyses.

Each judgement must be supported by explicit assumptions, described methods and quantified sensitivities. This documentation requirement represents a major cultural shift for teams accustomed to the French framework.

A more demanding closing process

Preparing IFRS consolidated accounts requires a more robust closing process than that needed for statutory accounts under French standards. Consolidation adjustments, elimination of internal transactions, currency conversions and IFRS adjustments all demand finer data collection, structured verification procedures and a controlled closing timetable.

Sector studies from 2025 reveal that finance teams spend approximately 80% of their time on data collection and consolidation reconciliation, leaving only 20% for strategic analysis. Organisations that have modernised their financial consolidation platforms have recovered up to 90% of the time previously spent on manual tasks.

A need for specific expertise

Preparing IFRS accounts requires technical competencies that few generalist accountants naturally possess. Mastery of IFRS 15 (revenue recognition), IFRS 16 (leases), IFRS 9 (financial instruments) and IAS 36 (asset impairment) demands specific training and regular practice.

For a mid-sized group, the IFRS transition typically represents a 6 to 18 month investment, including team training, information system adaptation, internal control procedures and the production of a first complete set of IFRS accounts.

CSRD convergence and extra-financial reporting

The 2026 regulatory landscape adds an additional layer of complexity. Nearly 15,000 European companies are now subject to the expanded obligations of the CSRD (Corporate Sustainability Reporting Directive), with assurance requirements progressively aligning with those applied to financial data. The IFRS S1 and S2 standards from the ISSB (International Sustainability Standards Board) converge toward the same objective: integrated reporting where financial and extra-financial information share the same governance framework and quality standards.

Hayot Expertise advice: IFRS adoption makes sense when the expected external benefit (investor credibility, financing access, benchmarking quality) remains consistent with the internal production and governance effort it requires. Groups that adopt IFRS before their closing process, data quality and accounting team are ready consistently produce poor-quality first-year accounts that damage rather than improve their credibility.

We recommend analysing four dimensions before committing to an IFRS transition:

1. Stakeholder expectations

Are investors, lenders or future acquirers genuinely expecting IFRS accounts? Is the project driven by an identified external demand or by internal ambition without a concrete outlet? An honest diagnostic of market expectations is the essential starting point.

2. Existing reporting maturity

Can the group already close its accounts reliably and within controlled timeframes under local standards? If not, addressing that question first is more urgent than embarking on an IFRS transition. IFRS amplifies the weaknesses of an existing closing process; it does not resolve them.

3. The impact of group-specific IFRS standards

Which IFRS standards will have the greatest impact on the group's specific situation? Lease contracts (IFRS 16), revenue recognition (IFRS 15), business combinations (IFRS 3), financial instruments (IFRS 9), impairment tests (IAS 36)? A preliminary impact mapping exercise enables the project to be properly scoped.

4. Mobilisable resources

Does the finance team have the capacity to lead the IFRS transition while maintaining day-to-day operations? Is external support needed? Are the budget and timetable realistic given the complexity of the consolidation scope?

Our experience leads us to recommend the following steps:

1. ▸

   Gap analysis: identify the differences between current accounting practices and IFRS requirements, standard by standard, for each significant type of group transaction.

2. ▸

   Quantitative impact mapping: assess the financial impact of the transition on the balance sheet, income statement and key indicators (EBITDA, net debt, equity).

3. ▸

   Information system adaptation: verify that the ERP, consolidation tools and inter-company data flows are compatible with IFRS requirements.

4. ▸

   Team training: organise targeted training sessions on the IFRS standards most relevant to the group, with practical cases drawn from the group's sector of activity.

5. ▸

   Dry-run IFRS accounts: prepare a first complete set of IFRS accounts for a historical period, in order to validate methodologies and identify final adjustments before the first official publication.

6. ▸

   Stakeholder communication: anticipate questions from investors, banks and statutory auditors about the impacts of the transition and changes in presentation.

We support groups through gap analysis, impact mapping, team training and the preparation of first-time IFRS accounts.

In 2026, IFRS standards for consolidated accounts are a genuine lever for transparency, credibility and group management quality. The EU's adoption of IFRS 18 in February 2026 and the March 2026 update to IFRS for SMEs demonstrate the continued vitality and relevance of this framework.

IFRS are only useful, however, when the organisation has the process maturity, data governance and team capability to absorb what the standards require. The preparation window for 2027 requirements is gradually closing: groups that anticipate are transforming a compliance constraint into a competitive advantage.

Are IFRS standards mandatory for all companies in France?

No. In France, IFRS standards are mandatory only for the consolidated accounts of companies listed on an EU regulated market (European Regulation n° 1606/2002). Unlisted groups may apply them voluntarily for their consolidated accounts, subject to an irrevocable option exercised year by year. Statutory accounts remain subject to the French general chart of accounts (PCG) in all cases.

What is the impact of IFRS 18 on 2026 consolidated accounts?

IFRS 18, adopted by the EU on 13 February 2026 (Regulation EU 2026/338), enters into force on 1 January 2027 with retrospective application. This means that 2026 accounts will need to be restated according to the new requirements: restructuring of the income statement with three mandatory categories (operating, investing, financing), new subtotals such as operating profit, and enhanced transparency on alternative performance measures (APMs). ESMA published a public statement on 17 February 2026 to guide implementation.

How long does an IFRS transition take?

For a mid-sized group (ETI), the transition to IFRS standards typically requires 6 to 18 months. This includes gap analysis, impact mapping, information system adaptation, team training and the production of a first dry-run set of IFRS accounts. More complex groups (multi-country, multi-currency, numerous subsidiaries) may need 18 to 24 months.

What are the costs of voluntary IFRS adoption?

Costs vary depending on group size and consolidation scope complexity. For a French mid-cap company, budget between €30,000 and €100,000 for the transition phase (diagnostic, training, tool adaptation, external support), plus recurring annual costs for producing and auditing IFRS accounts (€15,000 to €50,000 per year depending on complexity). These investments are generally offset by easier access to financing and reduced due diligence costs.

What is the difference between IFRS and French GAAP for consolidated accounts?

The French general chart of accounts (PCG) is based on precise rules and a primarily historical cost approach. IFRS standards prioritise fair value, professional judgement and an economic approach to transactions. The major differences concern lease contract treatment (capitalisation under IFRS 16), revenue recognition (IFRS 15), financial instruments (IFRS 9) and impairment testing (IAS 36). IFRS also requires significantly more detailed notes to the financial statements.
