ASU 2023-09 updates ASC 740 to improve transparency in income tax disclosures, focusing on tax exposures and cash flow insights. Key changes include expanded rate reconciliation, disaggregated tax payments, and new reporting requirements for public and non-public entities.

By Lindsay Haskell and Lauren Staub

In December, 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2023-09 (ASU 2023-09), introducing significant changes to income tax footnote disclosures for entities subject to ASC 740.

Key adoption dates

  • Public companies: Annual periods beginning after December 15, 2024
  • Non-public entities: Annual periods beginning after December 15, 2025
  • Entities may adopt the amendments prospectively or elect retrospective application

FASB updated the requirements for income tax footnote disclosures to enhance transparency and usefulness to investors, lenders, creditors, and other users of financial statements. Specifically, the updates are designed to help these users better understand tax law exposures and provide more detailed information for cash flow forecasts.

The amendments expand effective rate reconciliation disclosures, require detailed disclosures of taxes paid, along with other additional disclosures relating to an entity’s operations, the highlights of which are provided below.  

Rate Reconciliation Enhancements

For greater consistency, the following specific categories are required to be disclosed for public business entities using both percentages and amounts (for non-public entities percentage disclosure not required): 

  • State and local income taxes, net of federal benefit 
  • Foreign taxes 
  • Effect of changes in tax laws or rates 
  • Effect of cross-border tax laws 
  • Tax credits 
  • Changes in valuation allowances 
  • Non-taxable or nondeductible items 
  • Changes in unrecognized tax benefits 

Additional disclosures are required for the effect of cross-border tax laws, foreign taxes (including details by country), a qualitative description of state and local income taxes jurisdictions that make up the majority of the amount, and unrecognized tax benefits. If not otherwise evident, additional qualitative disclosures are required for specific categories of reconciling items and individual jurisdictions that result in a significant difference between the statutory tax rate and the effective tax rate. 

Income Taxes Paid 

For all entities, the amount of income taxes (net of refunds) paid must be disclosed, categorized by federal, state, and foreign taxes. Further details as to payments made to individual jurisdictions must be presented for all amounts greater than 5% of the total income taxes paid.  

Other Disclosures 

Entities are required to report income or loss from continuing operations before income taxes, segmented by domestic and foreign sources. They must also disclose income tax expense from continuing operations, broken down into federal, state, and foreign components.

Further required disclosures include:

  • The statutory tax rate applied, with an explanation if it differs from the federal rate
  • Any changes in valuation allowances related to deferred tax assets

What to do now

Review your current tax disclosures for compliance with the updated standards. Work with tax and accounting teams to gather required data, choose between prospective or retrospective adoption. If you’re a private company, evaluate the potential benefits of early adoption for 2025.

We suggest that companies begin working with their tax advisors now to understand these new requirements, assess what additional information is to be disclosed, and determine how to gather that information in advance of the effective dates.
