ISA 800 (Revised) – Special Considerations: Audits of Financial Statements Prepared In Accordance With Special Purpose Frameworks

ISA 800 (Revised) DEALS with special considerations in the APPLICATION of (ISAs 100-700) to an audit of financial statements prepared in accordance with a ‘Special Purpose Framework’.

What is ISA 800?

ISA 800, formally titled “Special Considerations — Audits of Financial Statements Prepared in Accordance with Special Purpose Frameworks,” is an International Standard on Auditing issued by the International Auditing and Assurance Standards Board (IAASB). It addresses the unique considerations that arise when an auditor is engaged to report on financial statements that are not prepared under a general purpose financial reporting framework.

Unlike most financial statements prepared for a broad audience of investors, regulators, and the public at large, special purpose financial statements are tailored to meet the information needs of a specific group of users such as a lender, a government agency, or the parties to a contract. ISA 800 equips auditors with the specific guidance they need to navigate these engagements appropriately.

The auditor shall determine whether the financial reporting framework used is acceptable in the context of the specific purpose of the financial statements.

— ISA 800, Para. 8

ISA 800 does not replace the foundational auditing standards, it supplements them. All other applicable ISAs continue to apply to special purpose audits, with ISA 800 addressing only those areas where additional, modified, or alternative considerations are necessary.

Scope & Application

ISA 800 applies to audits of complete sets of financial statements prepared in accordance with a special purpose framework. It does not apply to:

  • NOT
    Single Financial Statements

    Audits of individual financial statements (e.g., a single balance sheet) are governed by ISA 805, not ISA 800.

  • NOT
    Specific Elements or Line Items

    Audit engagements covering specific elements, accounts, or items within a financial statement are addressed separately under ISA 805.

  • NOT
    General Purpose Frameworks

    Financial statements prepared under IFRS or national GAAP designed for general use are covered by ISA 700 series, not ISA 800.

ISA 800 reads alongside the full suite of ISAs. The auditor brings the same professional scepticism, risk assessment, and evidence-gathering rigour to a special purpose engagement as to any other audit.

Special Purpose Frameworks

A special purpose framework is a financial reporting framework designed to meet the financial information needs of specific users. ISA 800 identifies four principal types:

Framework Type
Common Users & Applications
Cash Basis

Records transactions only when cash is received or paid. Provides a simple picture of cash flows.

Small businesses, sole traders, non-profit organisations, and government entities tracking cash positions.

Tax Basis

Prepared using principles and rules established by the applicable tax authority, such as HMRC or the IRS.

Tax authorities, business owners assessing tax liabilities, and tax-focused due diligence engagements.

Regulatory Basis

Complies with requirements of a specific regulator rather than general accounting standards.

Financial regulators (banking, insurance), government bodies requiring statutory regulatory returns.

Contractual Basis

Prepared to comply with financial reporting provisions specified in a contract or loan agreement.

Lenders, bondholders, joint venture partners, and counterparties to financial covenants.

The framework need not be a formally codified standard, it may simply be the financial reporting requirements set out within a particular agreement. What matters is that it constitutes a set of criteria used to prepare the financial statements.

Objectives Under ISA 800

The overarching objectives of the auditor under ISA 800 are to:

  • OBJ 1
    Address appropriateness of the framework

    Determine whether the special purpose framework adopted is an acceptable basis for preparing financial statements in the given context.

  • OBJ 2
    Obtain sufficient, appropriate evidence

    Gather enough audit evidence to form an opinion on whether the financial statements are prepared, in all material respects, in accordance with the applicable special purpose framework.

  • OBJ 3
    Express a clear opinion

    Report clearly and appropriately, including adding an emphasis of matter paragraph that draws users’ attention to the basis of accounting and restricts distribution where necessary.

Key Requirements

Acceptability of the Framework

Before accepting or continuing an engagement, the auditor must evaluate whether the special purpose framework is acceptable. Factors to consider include: whether the framework is relevant to the users’ needs, whether it is appropriate for the type of entity, and whether it complies with applicable laws and regulations.

If the framework is prescribed by law or regulation, the auditor generally accepts it as acceptable, but remains alert to any requirement to use supplementary disclosures if the prescribed framework would otherwise result in misleading financial statements.

Practitioner Note

When the financial reporting framework is embedded in a contract or loan agreement, the auditor must read those provisions carefully. Ambiguous or incomplete contractual requirements can create significant difficulties in forming an opinion.

Understanding the Entity and Its Framework

Under ISA 315, the auditor must obtain a sufficient understanding of the entity. For special purpose engagements, this includes understanding:

  • The nature and purpose of the financial statements

    Why these statements are being prepared and who will rely on them.

  • The specific requirements of the framework

    What measurements, recognition, and disclosure criteria apply under the framework.

  • Any departures from the framework

    Whether management has departed from framework requirements and the effect on the financial statements.

Supplementary Information

When special purpose financial statements contain supplementary information (e.g., information presented alongside but outside the scope of the framework), the auditor must clearly distinguish whether that supplementary information is covered by the audit opinion or not. If it is not, the auditor should clearly state that in the audit report.

Audit Evidence & Materiality

The standard evidence-gathering requirements of ISA 500 and associated standards apply fully to ISA 800 engagements. However, the concept of materiality may function differently in a special purpose context.

Under ISA 320, materiality is determined with reference to the needs of the intended users. For a lender’s covenant-based financial statements, the materiality threshold may be far lower than for a general-purpose audit; because even a small misstatement could affect covenant compliance. For a tax-basis engagement, the tax authority may have specific rules about what differences are material.

The concept of materiality is applied by the auditor in the context of the financial reporting framework being used and the needs of the intended users of those financial statements.

— ISA 800, Application Material

The auditor’s assessment of risk, design of procedures, and evaluation of misstatements must all be calibrated to the specific context and user needs of the engagement. This makes ISA 800 engagements highly context-sensitive, no two special purpose audits are identical.

The Auditor’s Report Under ISA 800

The audit report issued under ISA 800 generally follows the structure prescribed in ISA 700 (Revised), but with two distinctive additional elements:

  • ADD 1
    Emphasis of Matter — Basis of Accounting

    The auditor must include an Emphasis of Matter paragraph drawing attention to the note in the financial statements that describes the basis of accounting used, and the fact that the financial statements may not be suitable for another purpose. This paragraph is included even when the audit opinion is unmodified.

  • ADD 2
    Restriction on Distribution or Use

    Unless the framework is prescribed by law or regulation and the financial statements are publicly available, the audit report should include a statement restricting its distribution or use to the intended users identified within it.

Modified Opinions

ISA 705 governs modifications to the auditor’s opinion. If the financial statements are materially misstated relative to the special purpose framework, or if the auditor cannot obtain sufficient evidence, modifications (qualified opinion, adverse opinion, or disclaimer of opinion) apply in the same way as in a general purpose audit.

The Prescribed Format Exception

Some regulatory bodies or laws prescribe the form and content of the auditor’s report. Where that prescribed format differs significantly from ISA 800 requirements, the auditor should evaluate whether users might misunderstand the audit or the opinion expressed. If so, the auditor should consider adding additional explanatory language within the report.

ISA 800 vs ISA 700: Key Differences

ISA 700 (Revised) is the primary standard governing audit reports on general purpose financial statements. ISA 800 modifies and extends ISA 700 for special purpose engagements. The table below summarises the principal differences:

Practical Application

When Are ISA 800 Engagements Common?

ISA 800 engagements arise frequently in the following scenarios:

  • EX
    Bank Lending & Debt Covenants

    Lenders routinely require audited financial statements prepared on a contractual basis aligned to their covenant definitions, often different from statutory GAAP figures.

  • EX
    Tax Authority Submissions

    Some jurisdictions require audited tax-basis financial statements alongside or instead of GAAP financial statements for corporate tax assessments.

  • EX
    Regulated Entities

    Financial services firms, insurance companies, and utilities often must produce regulatory-basis financial statements that differ materially from GAAP, and which require separate audit opinions.

  • EX
    Joint Ventures & Partnership Agreements

    Partners in joint ventures may require audited financial statements on a cash or agreed contractual basis to assess performance and distributions.

Common Pitfalls to Avoid

Audit Risk

A frequent error is failing to include the required Emphasis of Matter paragraph in the audit report, or omitting the restriction on use clause. Both omissions are departures from ISA 800 requirements, even where the financial statements themselves are fairly presented. Equally, auditors sometimes neglect to reassess materiality thresholds for the specific users, applying general-purpose materiality to a lender’s covenant audit can result in significant audit risk.

Documentation Considerations

ISA 230 requires auditors to document their work sufficiently to enable an experienced auditor, having no prior connection to the engagement, to understand the nature, timing, and extent of procedures performed. For ISA 800 engagements, documentation should specifically address:

The auditor’s conclusion on the acceptability of the special purpose framework; the determination of materiality for the specific users; any supplementary information included in the financial statements and how it has been treated in the audit opinion; and the rationale for the wording of the Emphasis of Matter and restriction paragraphs.

Frequently Asked Questions

ISA 800 is an International Standard on Auditing titled “Special Considerations — Audits of Financial Statements Prepared in Accordance with Special Purpose Frameworks.” Issued by the IAASB, it provides auditors with guidance for engagements where financial statements are prepared using a framework designed for specific users rather than the general public.

ISA 800 (Revised) became effective for audits of financial statements for periods ending on or after 15 December 2009. Many jurisdictions adopted it as part of the broader Clarity ISA reform project. It has subsequently been amended to align with revisions to other ISAs.

Yes. ISA 800 specifically requires the auditor to include an Emphasis of Matter paragraph in the audit report, even where an unmodified (clean) opinion is expressed. This paragraph draws attention to the special purpose basis of accounting and alerts users to the restricted nature of the financial statements.

No. Summary financial statements derived from audited financial statements are governed by ISA 810, not ISA 800. ISA 800 applies specifically to complete sets of financial statements prepared under a special purpose framework.

ISA 800 covers audits of complete sets of financial statements prepared under a special purpose framework. ISA 805 covers audits of single financial statements and specific elements, accounts, or items of a financial statement such as a standalone balance sheet or an audit of debtors only. Both standards address special purpose considerations, but for different scopes of financial information.

Yes, but when financial statements and the related audit report are available to the public, the restriction on use clause in the audit report is not required. However, the Emphasis of Matter paragraph describing the basis of accounting is always required regardless of whether the statements are publicly available or restricted.
