IFRS stands for International Financial Reporting Standards. These are a set of global accounting rules that define how companies prepare and present their financial statements. Used in more than 160 jurisdictions worldwide, IFRS helps businesses speak a common financial language, making it easier for investors, regulators, and partners to compare performance across borders.
What is IFRS?
IFRS is a collection of accounting standards that tell companies how to record transactions, value assets, and report financial results. Think of them as a shared rulebook: when everyone follows the same rules, financial statements become easier to read and trust.
Before IFRS, each country had its own set of accounting standards. That made it difficult to compare a company in the UK with one in Germany or Australia. IFRS solves this by providing a single, internationally recognised framework.
In practice, IFRS covers everything from how you recognise revenue and measure intangible assets to how you report leases and financial instruments. If your business operates internationally or reports to stakeholders in multiple jurisdictions, IFRS is likely part of your compliance requirements.
Who develops IFRS standards?
IFRS standards are developed by the International Accounting Standards Board (IASB), an independent body based in London. The IASB sits within the IFRS Foundation, a not-for-profit organisation that oversees standard-setting and promotes global adoption.
The IASB consults with regulators, businesses, investors, and auditors worldwide before issuing new or updated standards. This process ensures that the rules reflect real-world business practices and meet the needs of those who use financial information.
Key IFRS Standards
There are currently over 40 active IFRS and IAS standards. For a complete list of IFRS standards, the IASB maintains an official register at ifrs.org. Here are the ones most relevant for finance teams:
- IFRS 9 (Financial Instruments): Covers how to classify, measure, and account for financial assets and liabilities.
- IFRS 15 (Revenue from Contracts with Customers): Sets out when and how to recognise revenue, which directly affects how your bookkeeping team records sales.
- IFRS 16 (Leases): Requires most leases to appear on the balance sheet, changing how businesses report prepaid expenses and long-term commitments.
- IFRS 17 (Insurance Contracts): Introduces a consistent approach to accounting for insurance contracts.
- IFRS 18 (Presentation and Disclosure in Financial Statements): The newest standard (effective 2027), which will improve how companies structure their income statements and present performance metrics.
Beyond financial reporting, the IFRS Foundation's International Sustainability Standards Board (ISSB) has issued IFRS S1 and IFRS S2 for sustainability-related disclosures. These are separate from the accounting standards but sit under the same governance framework.
IFRS vs GAAP: Key Differences
IFRS and GAAP (Generally Accepted Accounting Principles) are both sets of accounting standards, but they differ in important ways.
- Approach: IFRS is principles-based; GAAP (US GAAP) is rules-based.
- Inventory: LIFO method is not allowed under IFRS; LIFO is permitted under GAAP.
- Development costs: Can be capitalised under IFRS; generally expensed under GAAP.
- Lease reporting: IFRS uses a single model (IFRS 16); GAAP uses two models (ASC 842).
- Adoption: IFRS is used in 160+ jurisdictions; GAAP is primarily used in the US.
The biggest distinction is philosophy. IFRS is principles-based, meaning it sets broad guidelines and lets companies apply judgement. US GAAP is rules-based, with detailed instructions for specific scenarios. Neither is better or worse; they simply reflect different regulatory traditions.
UK GAAP vs IFRS: In the UK, publicly listed companies must use IFRS. Private companies can choose between IFRS and UK GAAP (FRS 102). UK GAAP is simpler and designed for domestic reporting, while IFRS is required if you want your financial statements to be internationally comparable.
IFRS vs IAS: What's the Difference?
IAS (International Accounting Standards) are the predecessor to IFRS. They were issued by the International Accounting Standards Committee (IASC) before the IASB took over in 2001. The IASB adopted all existing IAS standards and began issuing new ones under the IFRS name.
Many IAS standards remain in force today (for example, IAS 16 on property, plant, and equipment). The key difference is simply timing: IAS standards came first, and IFRS standards are newer additions to the same framework. You will see both referenced in financial reporting requirements.
Who Uses IFRS?
IFRS is required or permitted in more than 160 jurisdictions, including:
- United Kingdom: IFRS in the UK requires all London Stock Exchange-listed companies to prepare consolidated financial statements using UK-adopted IFRS. Private UK companies can choose between IFRS and UK GAAP (FRS 102).
- European Union: Required for all EU-listed companies since 2005.
- Canada, Australia, South Korea, Brazil: All require or permit IFRS for public companies.
The notable exception is the United States, which still uses US GAAP for domestic companies, though many US-listed foreign companies report under IFRS.
For businesses with international operations, IFRS compliance ensures your financial reporting is understood by stakeholders everywhere, from investors to tax authorities.
Why IFRS Matters for Businesses
IFRS is not just an accounting technicality. It has real consequences for how your finance team works day to day:
- Comparability: Investors and lenders can compare your performance with competitors in other countries, which can improve access to capital.
- Transparency: Standardised reporting reduces the risk of misunderstanding or misrepresentation in financial statements.
- Cross-border operations: If you operate in multiple jurisdictions, IFRS can significantly reduce the need to maintain separate sets of books. However, companies may still need separate records to meet local IFRS modifications, statutory reporting requirements, or tax compliance rules in certain jurisdictions.
- Compliance: Failing to follow required IFRS standards can result in regulatory penalties and damaged credibility.
For finance teams managing company spend, IFRS standards like IFRS 16 (leases) and IFRS 15 (revenue) directly affect how you categorise and report expenses. Getting this right starts with accurate data capture and consistent invoice coding from the start.
IFRS for SMEs
Not every business needs to follow the full set of IFRS standards. The IASB has published a simplified version called IFRS for SMEs (Small and Medium-sized Enterprises).
IFRS for SMEs reduces the number of standards and simplifies many requirements. For example, it streamlines rules around financial instruments and removes some disclosure requirements that are only relevant to large public companies.
This version is designed for private companies that do not have public accountability but still want (or need) to follow internationally recognised standards. Nearly 90 jurisdictions currently permit or require IFRS for SMEs.
