The purpose of this study is to analyze the ability to pay principles related to the components of other comprehensive income (OCI). As the Income Tax Law adopts the ability to pay principles in fulfilling equality principles, we elaborate the data on hand to understand the suitable tax imposition on OCI for the Indonesian context. Hence, this study's other output is to serve recommendations to tax authorities in Indonesia regarding tax options finding. We applied qualitative methods, using documentary materials, collection of statements, and in-depth interviews. The primary interviewees were policymakers, constituents of financial accounting standards (Standar Akuntansi Keuangan; SAK), academic scholars, tax consultants, and taxpayers. Our findings are that the different nature of the components of OCI requires different treatment to ensure the principle of equality performs properly. This study concludes that the income tax imposition on the components of OCI in Indonesia needs to be distinctly regulated based on markto-market, realization, or hybrid taxation. The tax policy option for the gains and losses of financial statements for overseas business activities is realization taxation. It is better to choose hybrid taxation for unrealized gains and losses of the changes in revaluation surplus of fixed assets and intangible assets. A mark-to-market taxation approach prevails only if the tax authority issued approval for the revaluation. It remains for realization taxation if there is no approval. We should also impose realization taxation for the remaining components. These are our recommendations.
