IFRS 18 replaces IAS 1 for reporting periods beginning on or after 1 January 2027. Because comparatives are required, the numbers you report for 2026 will need to be restated in the new format — which makes this a 2026 problem, not a 2027 one. It changes how the income statement is structured, brings management’s own performance measures inside the audited accounts, and reshapes the cash flow statement.
What is IFRS 18?
IFRS 18 Presentation and Disclosure in Financial Statements is the new standard governing how financial statements are presented. It replaces IAS 1 entirely and amends several other standards. It does not change how you measure assets, liabilities, revenue or expenses — recognition and measurement stay where they are. What changes is the shape of the statements and what you must disclose.
That distinction matters for planning. Your accounting policies largely survive. Your reporting templates, chart of accounts groupings and management pack probably do not.
The income statement gets a defined structure
Under IAS 1, companies had wide latitude in how they laid out profit or loss. Two similar businesses could present it in genuinely non-comparable ways, and “operating profit” meant whatever each preparer decided it meant.
IFRS 18 imposes defined categories, with required subtotals. Income and expenses are classified into operating, investing and financing categories, and the standard requires an operating profit subtotal presented on a consistent basis.
For most UAE SMEs the practical effect is that operating profit becomes a defined number rather than a management choice. If your bank covenants or shareholder reporting reference an operating profit figure you defined yourself, check now whether it still means the same thing in 2027.
Management-defined performance measures come inside the audit
This is the change with the sharpest edge. If management publishes a performance measure that is not defined by IFRS — adjusted EBITDA, underlying profit, normalised earnings — and uses it publicly to communicate performance, IFRS 18 requires it to be disclosed in the notes to the audited financial statements, reconciled to the nearest IFRS subtotal, with an explanation of why management considers it useful.
Those measures used to live in investor decks and press releases, outside the audit boundary. Bringing them inside means your auditor will test them. Adjustments that were never scrutinised now have to be justified and applied consistently year on year.
If your business reports an adjusted figure to investors, lenders or a parent company, identify it now and be ready to defend every adjustment in it.
The cash flow statement changes too
Two specific changes, both of which affect comparability with prior years:
- Operating profit becomes the starting point for the indirect method, replacing profit for the period.
- The classification options for interest and dividends are removed. Interest and dividends paid go to financing; interest and dividends received go to investing. The previous free choice is gone.
For a leveraged UAE business, moving interest paid out of operating cash flow can materially change reported operating cash generation. If a covenant or a valuation multiple references operating cash flow, that is worth modelling before the year it bites.
Aggregation and disaggregation
IFRS 18 sets clearer principles on grouping. Items should be aggregated where they share characteristics and disaggregated where they do not, and labels like “other expenses” are subject to more discipline — if a residual line is material, you have to explain what is in it.
In practice this pushes work back into the chart of accounts. Businesses running a coarse ledger with large catch-all accounts will find they cannot produce the required disaggregation without rebuilding the coding, and doing that mid-year is painful.
Why this matters specifically in the UAE
UAE financial statements are prepared under IFRS, and audited accounts are not optional in the way they once were. They are required for Qualifying Free Zone Person status, for most free zone licence renewals, for ICV certification, for a Tax Residency Certificate, and increasingly for banking.
So a presentation change is not just a reporting exercise. It touches the document that your tax position, your licence and your treaty claims all rest on. And because corporate tax starts from accounting profit, a restructured income statement changes the starting point of your tax computation even where the underlying numbers are identical.
What to do in 2026
- Identify your management-defined measures and decide whether you will keep publishing them.
- Map your current income statement to the new operating, investing and financing categories.
- Review your chart of accounts for catch-all lines that will not survive the disaggregation requirements.
- Model the cash flow reclassification if you carry meaningful debt.
- Warn your lenders and shareholders before the numbers move, not after.
The IFRS 18 series, in detail
This page is the overview. Each part of the standard has its own guide, because the classification calls are where the work actually is:
- The operating category — the residual that runs the business, and why it is defined by exclusion
- Investing and financing — the independent return test, and why a lease, a loan and a gratuity liability are treated differently
- Management-defined performance measures — adjusted EBITDA moving inside the audit boundary
- The cash flow statement changes — operating profit as the starting point and the end of classification choices
- The UAE transition plan — a six-step 2026 work programme, including the corporate tax bridge
If you read only one, make it the transition plan — comparatives mean the work belongs in 2026, not 2027.
Frequently asked questions
When does IFRS 18 take effect?
For annual reporting periods beginning on or after 1 January 2027. Because comparative figures are required, the 2026 numbers will need restating into the new presentation.
Does IFRS 18 replace IAS 1?
Yes, it replaces IAS 1 in full and amends several other standards.
Does IFRS 18 change how profit is measured?
No. Recognition and measurement are unchanged. What changes is presentation, structure and disclosure — but that can still move the subtotals people rely on.
What is a management-defined performance measure?
A subtotal of income and expenses that management uses publicly to communicate performance but that is not defined by IFRS — adjusted EBITDA is the classic example. Under IFRS 18 these must be disclosed and reconciled in the audited notes.
Does IFRS 18 apply to UAE SMEs?
It applies to entities reporting under full IFRS, which is the norm for UAE audited financial statements. Entities applying IFRS for SMEs follow a different framework, so confirm which basis your accounts are prepared on.
Will IFRS 18 affect my corporate tax?
Indirectly. UAE corporate tax starts from accounting profit, so a change in how that profit is presented changes the starting point of the computation even where the economics are identical.
What should we do first?
Map your current income statement to the new categories and identify any adjusted measures you publish. Those two steps expose most of the work.
