It’s time to prepare your business for a recent turn in the tax maze: new tax accounting standards for income issued by the Federal Accounting Standards Board (FASB) in December of 2023. Public companies must comply with ASU 2023-09, Improvements to Income Tax Disclosures for annual periods beginning after December 15, 2024. For private companies the standard goes into effect a year later, but don’t delay. You need this time to get ready.

ASU 2023-09 applies to companies of every size. If your organization has to pay business tax on income, you need to understand the new rules — and following them could yield tax benefits beyond avoiding noncompliance penalties.


What’s Changed: ASU 2023-09 in a Nutshell

New accounting standards mean changes for business accounting. ASU 2023-09 imposes a new requirement to include additional disclosures about an organization’s income tax in financial statements. The goal is to give investors and other stakeholders a better understanding of the company’s tax exposure and potential tax-associated risks.

The update requires all businesses to present a breakout of income taxes paid by jurisdiction, which will be a significant change for most companies. You’ll also need to provide a qualitative explanation of your effective tax rates in each jurisdiction.

Both public and private businesses must disclose in financial statement footnotes:

  • Disaggregated data showing the amount of income tax the entity paid at each jurisdictional level:
  • Disaggregated data showing income tax paid to any tax jurisdiction constituting at least 5% of the company’s total income tax during the covered period

New requirements for public companies

For public companies, ASU 2023-09 requires the disclosures to include a table comparing the statutory and effective tax rates paid.

  • Companies must provide this information in terms of amounts and percentages for each jurisdiction and specific reconciling categories.
  • They must also present breakdowns showing individual reconciling items that create a difference of 5% or more between statutory and effective tax rates.

You’ll need to make sure that the company’s financial statements include disaggregated data and a qualitative explanation for each of these categories:

  • State and local income tax, net of federal (national) income tax effect
  • Foreign tax effects
  • Effect of changes in tax laws or rates enacted in the current period
  • Effect of cross-border tax laws
  • Tax credits
  • Changes in valuation allowances
  • Nontaxable or nondeductible items
  • Changes in unrecognized tax benefits.

Additionally, public entities must provide a qualitative disclosure to explain the impact, nature and causes of individual reconciling items — and the reasoning behind how you chose to categorize them, if you had to make a judgment call.

New requirements for private companies

Nonpublic entities don’t have to present the numerical reconciliation that ASU 2023-09 requires from public companies. However, private companies must include a qualitative disclosure addressing the difference between the statutory tax rate and the organization’s effective tax rate. You’ll need to provide this information for each jurisdiction, broken down into the same categories of reconciling items that public companies must disclose.


What’s Critical: FAQs for ASU 2023-09 Compliance

New regulations that require accounting changes typically inspire lots of questions. To help you get ahead of the new rules, here’s a look at some common queries we’re hearing from CFOs and other business leaders.

Q: How big of a change does the update really represent?

A: Depending on the nature of your business, compliance with ASU 2023-09 could be anything from a nothingburger to a major undertaking. Generally speaking, businesses that incur income tax liability in more jurisdictions will be most heavily impacted — whether you’re leading a domestic company with nexus in multiple states or a multinational company with revenue sourced around the globe.

Your relative difficulty in accessing disaggregated data is another key controlling factor. If your company doesn’t currently collect this type of information, compliance will pose more of a challenge.

If your business has income in only one tax jurisdiction, ASU 2023-09 should have minimal impact. Likewise, if your accounting processes already generate the information required for disclosure. Companies with advanced tax and accounting software, such as an enterprise resource planning (ERP) system, typically already have or can easily access the needed information.

The bottom line: if you have income tax liabilities in multiple jurisdictions or use spreadsheets to track tax and revenue data, you should plan to devote significant resources for compliance.

A: The potential barriers to compliance revolve around two main factors:

  • The nature and extent of your organization’s tax exposure
  • The challenges of breaking out effective tax rates by separate jurisdictions, especially if you have significant foreign operations

If your business relies on spreadsheets, you may face significant challenges in obtaining the jurisdiction-level data you need.

Private companies should also consider the difficulty of calculating and explaining the effective tax rate. Multiple factors can influence your calculations, and teasing out the various impacts can be tricky. For example, these are just a few of the things that impact your effective tax rate:

  • Permanent differences
  • Valuation allowances
  • State taxes
  • Foreign tax rate differentials

Evaluating all the potential factors now will help you make accurate disclosures once the ASU takes effect.

Q: Where do I find the information that ASU 2023-09 requires for disclosure?

A: If you use accounting software that already collects this information, you should be able to include it in your financial statements with little difficulty. However, you may need to dig into the software to find it. Even if your system can show you disaggregated data, you may need to change certain settings to access it or run specific reports that will generate the information. Some companies that use spreadsheets may also have the ability to see disaggregated data.

Q: What if the required information doesn’t exist?

A: Many businesses — especially those using spreadsheets for accounting — don’t currently collect the disaggregated information needed for the ASU 2023-09 disclosures. If your organization isn’t currently collecting this data, it’s especially important that you begin working through the steps to compliance now, rather than waiting until the update takes effect.

Q: What should I do now to be ready for compliance with ASU 2023-09?

A: All public and private businesses should begin modeling the new jurisdictional tax disclosure requirements. If you already generate disaggregated tax data or your accounting package can do so easily, begin including this information in your reporting. Having a few months to work through the process will help you identify potential data gaps and adjust your reporting and financial statements as needed.

If your accounting doesn’t currently track disaggregated income tax information, mapping your path to compliance is an urgent priority. Investing in accounting software that can automatically generate disaggregated data is one option that’s effective and relatively easy to implement. But this can be costly, so it may not be the best choice for every business.

Start by setting up separate general ledger accounts for all material tax jurisdictions. This will make the data accessible, allowing you to track taxes paid, receivables, liabilities and other relevant data so you can make the appropriate disclosures.

  • Start by setting up separate general ledger accounts for all material tax jurisdictions. This will make the data accessible, allowing you to track taxes paid, receivables, liabilities and other relevant data so you can make the appropriate disclosures.
  • Once you’ve got the right granularity, you can tweak your accounting spreadsheets and processes to track all required data and adjust your financial reporting to permit compliance with the ASU.

Q: How will compliance with ASU 2023-09 benefit my business?

A: Besides avoiding potential consequences of noncompliance, here’s how the steps you take to comply with ASU 2023-09 can enhance your business performance:

  • Breaking out the tax profile by jurisdiction highlights the locations where you’re paying a higher effective tax rate. This may help you uncover tax savings opportunities.
  • Comparing effective tax rates and tax payments across jurisdictions can reveal inconsistencies and inefficiencies to address through strategic tax planning.
  • Gaining visibility into your global tax footprint lets business leaders factor tax implications into decisions around operations, investments and entity structures to optimize your overall tax position.
  • Tracking granular data may reveal overlooked tax credits and incentives in certain jurisdictions that your organization could qualify to claim.

How to Stay Ahead: ASU 2023-09 Compliance Checklist

As you’re getting ready to meet the updated accounting standards, this handy seven-point checklist can help you work through the process and see where you stand.

  • Assess your current capabilities. Review current accounting systems to determine if your existing accounting software or Excel models can disaggregate tax information by jurisdiction.
  • Identify data gaps. Figure out where disaggregated data doesn’t exist and make a detailed list of the additional information you’ll need for compliance.
  • Increase staff as needed. Make sure your finance and accounting team have the staffing resources to obtain, track and report the appropriate data for compliance.
  • Establish separate GL accounts. Set up separate general ledger accounts for material jurisdictions and adjust reporting processes to include this data.
  • Start modeling now. Don't wait until the last minute. Begin modeling jurisdictional breakouts using your current data to test the process and identify any issues.
  • Consider tax software. If you have significant foreign or multi-state operations, tax software may be a wise investment to automate jurisdictional reporting.
  • Call on outside expertise if needed. Reach out for help if you don't have the internal capability to model this kind of granular reporting. An experienced advisor can help you make a smooth transition, mitigate noncompliance risk and take advantage of any tax opportunities.
