Practical Solution
Special Corporate Tax for Defense
Special Corporate Tax for Defense is part of the Japan GAAP framework.
STATUS NOTE: Confirmed issued by the ASBJ on February 27, 2026 as a "Practical Solution" – a narrower, often TENTATIVE or transitional document type (distinct from a full Accounting Standard), explicitly labelled here as addressing "tentative treatment." Its precise substantive content beyond this general characterisation should be verified against ASBJ's current published materials.

Conceptual Framework Linkage
Interim guidance for a newly introduced, narrow tax measure
This Practical Solution provides GUIDANCE for accounting for and DISCLOSING Japan's "SPECIAL CORPORATE TAX FOR DEFENSE" (防衛特別法人税) – a NEWLY introduced corporate tax measure connected to Japan's INCREASED defense spending – issued on a TENTATIVE basis, REFLECTING that detailed practical questions arising from a BRAND-NEW tax measure are often addressed THROUGH this narrower document type FIRST, PENDING fuller integration into the general tax accounting standards (ASBJ Statements No. 27 and No. 28) if and when WARRANTED.

Scope – a New Defense-Funding Tax Measure
Companies subject to Japan's special corporate tax for defense
This guidance applies to companies SUBJECT to Japan's special corporate tax FOR DEFENSE – a measure introduced as PART of the broader Japanese government's response to INCREASED defense budget requirements, ADDING to the existing layered tax system already addressed by ASBJ Statement No. 27 (Current Income Taxes – see the companion poster).

Why a "Practical Solution," Not a Full Accounting Standard
A narrower, faster-issued document type for urgent, specific questions
"PRACTICAL SOLUTIONS" (実務対応報告) are a DISTINCT, NARROWER document type WITHIN the ASBJ's OUTPUT – typically addressing a SPECIFIC, often URGENT practical question (frequently arising from a NEW law or regulation) MORE QUICKLY than the FULL due-process cycle a comprehensive Accounting Standard would require. A NEWLY introduced tax measure, such as this defense-funding tax, is a TYPICAL trigger for this document TYPE – GIVING preparers TIMELY guidance WITHOUT waiting for a FULL Statement-level project.

What "Tentative Treatment" Signals
Guidance subject to potential future refinement
The EXPLICIT use of "TENTATIVE" in this document's title signals that the ASBJ RECOGNISES the guidance may need FURTHER refinement as the tax LAW's practical application becomes CLEARER over time, or as related legislative DETAILS are finalised – a PRUDENT, transparent approach to providing TIMELY guidance for a genuinely NEW, evolving tax measure WITHOUT overstating the guidance's PERMANENCE.
5
The General Practice of Tentative Practical Solutions for New Tax Measures
A recurring ASBJ response to significant new tax legislation
This APPROACH – issuing a TENTATIVE Practical Solution PROMPTLY following significant new tax LEGISLATION – MIRRORS how the ASBJ has PREVIOUSLY responded to OTHER major new tax developments (for example, GUIDANCE addressing the treatment of Japan's implementation of the OECD's GLOBAL MINIMUM TAX rules) – a RECURRING, well-established ASBJ practice of providing TIMELY, PRACTICAL guidance for SIGNIFICANT new tax measures AHEAD of any eventual FULL integration into the general tax accounting standards.

Worked Example – Applying a Tentative Practical Solution
Recognising a new tax liability under interim guidance
Example: A company subject to the new defense tax measure
A company determines it is subject to the special corporate tax for defense for the current fiscal year, following the newly introduced tax measure.
The company applies this Practical Solution's TENTATIVE guidance to determine the APPROPRIATE recognition and disclosure treatment for the resulting tax liability – while remaining ALERT to the possibility that FURTHER ASBJ refinement of this guidance MAY follow as the tax measure's practical application matures.

Disclosure Requirements
What this Practical Solution addresses
Recognition and measurement of the special corporate tax for defense liability Disclosure of the nature and tentative basis of the accounting treatment applied
8
Critical Judgments & Estimates
Where judgement matters most
SIGNIFICANT JUDGEMENTS
Whether an entity is subject to the special corporate tax for defense, and how it interacts with existing enterprise/corporation tax treatment
SIGNIFICANT ESTIMATES
Estimated tax liability under a newly introduced, still-evolving tax measure
9
Relationship to IAS/IFRS and US GAAP
A genuinely Japan-specific tax policy development
LIKE the SIZE-BASED enterprise tax classification question addressed in ASBJ Statement No. 27 (see the companion poster), this special defense-funding tax is a GENUINELY Japan-SPECIFIC tax policy development, WITHOUT a direct IFRS or US GAAP counterpart of the SAME type – NEITHER IAS 12 nor ASC 740 addresses a comparable NATIONAL defense-funding surtax construct.
