Document a proposed accounting-policy change before using it

Write down what the company currently does, where that policy is documented, and the transaction population it affects. Describe the proposed treatment precisely enough for another accountant to compare it with the existing practice. A request to make reporting more accurate does not identify the accounting decision or the work required to implement it.

Include the reason for the request: a new standard, changed circumstances, a discovered error, or another identified issue. Ask the accountant to determine whether the proposal is actually a policy change, an estimate change, a presentation change, or correction of an error. The label chosen by the project sponsor should not predetermine the reporting treatment.

IAS 8 provides IFRS criteria for selecting and changing policies and distinguishes policy changes from estimate changes and errors. Policy changes generally involve retrospective application unless specified transition provisions or impracticability apply. The accountant must assess the actual requirements and exceptions; other frameworks need their own analysis.

Retain the specific authoritative guidance used, its effective date, and any adoption decisions. A new accounting-system feature or a preference for simpler bookkeeping is not itself authoritative guidance. If the company keeps financial and tax records on different bases, identify the specialist coordination needed without assuming that a financial-reporting policy change automatically changes a tax method.

List the accounts, transactions, periods, entities, and disclosures that may change. Determine which historical information is available and where reconstruction would be required. Prepare a comparison of the existing and proposed calculations using the same source population. Keep uncertain inputs and incomplete periods explicit so the reviewer can assess the limitations.

In a hypothetical comparison, a proposed policy changes the carrying amount of an asset population by $45,000 at the assessment date. That closing difference does not explain how the effect divides among opening equity, current profit, comparative information, or other components. The accounting analysis must determine the period effects before anyone posts a single $45,000 adjustment.

Obtain a conclusion identifying the accepted treatment, authority, effective date, transition approach, disclosures, and approval. Then plan updates to schedules, journal rules, account mappings, and reporting instructions. Keep the prior policy and calculation versions so the team can explain why earlier reports differ from the new basis.

Test the revised process on a bounded population and reconcile its output to the approved calculation. Review edge cases that motivated the change and any transactions that should remain under the old treatment. A technically approved policy can still be implemented incorrectly if a recurring journal or source-system rule continues using the previous assumption.

Give the statement and management-reporting owners the approved period effects and presentation instructions. Distinguish changes in business performance from changes caused by the accounting basis. Have the accountant determine the required comparative treatment and disclosures. Avoid silently replacing historical management figures without preserving their previous definition and approved bridge.

Update the policy manual with the rationale and practical implementation references. Record the owner responsible for future review and the date the old routine stopped. The final file should connect the reason for the proposal to an approved accounting conclusion and an observable implementation, rather than leave a changed formula whose policy basis exists only in an email.
