Executive focus: who is in scope, how timing differences create regulatory assets and liabilities, interaction with IFRS 15, transition and the implementation work finance teams should start before 2029.
A new IFRS standard, not a narrow amendment
IFRS 20 Regulatory Assets and Regulatory Liabilities was issued by the IASB on 27 May 2026. It fills a long-standing gap for companies whose prices are set through a form of rate regulation that determines both how much compensation they are entitled to receive for regulated goods or services and when that compensation is reflected in customer rates.
The standard is expected to be particularly relevant to utilities, energy, water, gas and some transportation businesses. IFRS 20 is effective for annual reporting periods beginning on or after 1 January 2029, with early application permitted. It replaces IFRS 14 Regulatory Deferral Accounts and supplements the information provided when applying IFRS 15 Revenue from Contracts with Customers.
The economic problem: revenue timing can hide regulatory performance
Rate regulation can create a mismatch between the period in which a company supplies regulated goods or services and the period in which the regulator allows the related compensation to be included in customer prices. Under a revenue-only view, current-period financial performance may therefore omit an amount the company has already earned under the regulatory agreement or include an amount related to future supply.
IFRS 20 addresses these timing differences. A regulatory asset represents an enforceable present right to add an amount in determining a regulated rate in future periods because part of the total allowed compensation for goods or services already supplied will be included in revenue later. A regulatory liability reflects the converse obligation to deduct an amount from future regulated rates because current revenue includes compensation related to future supply.
Scope starts with the regulatory agreement
Not every company that operates in a regulated industry is automatically in scope. Finance must analyse whether the regulatory arrangement meets the standard’s requirements and creates enforceable rights and obligations concerning total allowed compensation and future regulated rates. Price caps, licences or general consumer-protection rules do not necessarily produce the same accounting outcome.
An implementation project should therefore begin with a contract-and-regulation inventory. Legal and regulatory teams identify the instruments that govern pricing; accounting maps the mechanisms that create timing differences; operations explain how service volumes and performance incentives are measured. The scope memo becomes the foundation for recognition and audit evidence.
Measurement needs a regulatory subledger mindset
Once regulatory assets and liabilities are identified, finance needs data capable of tracking their creation, recovery or fulfilment over time. The challenge resembles a subledger: each balance should have an originating regulatory mechanism, period, expected recovery profile and changes in estimates.
Companies that currently track these amounts only in regulatory filings or spreadsheets may face a substantial systems project. The general ledger needs controlled interfaces, and the close process needs reconciliations between regulatory calculations and IFRS 20 balances. Forecast data may also become relevant because expected timing affects measurement. Finance should design data lineage early, rather than treating IFRS 20 as a disclosure project in 2028.
Regulatory income and expense improve period matching
The new model introduces regulatory income and regulatory expense to reflect changes in regulatory assets and liabilities. This helps users understand the effect of rate regulation separately from revenue recognised under IFRS 15. The distinction is important because customer billings and regulatory compensation can move on different timelines.
Management reporting should mirror that distinction. A utility’s operational dashboard may need to reconcile IFRS 15 revenue, regulatory income or expense, cash collections and allowed returns. Without a bridge, management may struggle to explain why accounting performance differs from billed revenue or regulatory filings.
Transition offers two routes, but both require comparative information
IFRS 20 provides transition approaches. A company can apply the standard retrospectively in accordance with IAS 8 or use a modified retrospective approach with specified reliefs. Regardless of the route, adjusted comparative information is required for the immediately preceding period presented when IFRS 20 is first applied.
This makes 2029 feel closer than it looks. A calendar-year entity adopting in 2029 will need comparative information for 2028, so systems and data decisions should be operational before the first mandatory reporting year. Early gap analysis also helps determine whether historical regulatory data is sufficiently detailed to support transition.
Implementation should connect Accounting, Regulatory and FP&A
Regulatory accounting teams often work with models that are highly detailed but designed for tariff-setting rather than IFRS reporting. Group Accounting may understand IFRS presentation but not the mechanics of each rate case. FP&A may forecast customer prices and volumes without tracking the accounting timing differences. IFRS 20 forces these perspectives to connect.
A cross-functional data dictionary is a practical starting point: regulatory mechanism, allowed compensation, recovery period, volume driver, rate reset, incentive or penalty, IFRS balance and P&L effect. Ownership is then assigned for source data, calculation, journal entry and disclosure. This reduces the risk of parallel spreadsheets producing different versions of the same regulatory economics.
Preparation roadmap to 2029
- Identify regulatory agreements that may meet the IFRS 20 scope criteria.
- Inventory existing regulatory balances and timing-difference calculations.
- Map source data and assess whether a dedicated subledger or data layer is needed.
- Choose an initial transition strategy and test historical-data availability.
- Build bridges between IFRS 15 revenue, regulatory income/expense and cash collections.
- Engage auditors early on scope and measurement judgments.
- Use 2027–2028 parallel calculations to test controls before mandatory adoption.
