ASC 740 Tax Disclosures in 2026: The ASU 2023-09 Readiness Work Private Companies Should Start Now

ASC 740 workpapers have always mattered in an audit, lender review, acquisition diligence, or IPO-readiness process. FASB ASU 2023-09 raises the bar on the part many private companies historically treated as a footnote cleanup item: the income tax disclosure. The new standard does not change how current tax, deferred tax assets, deferred tax liabilities, uncertain tax positions, or valuation allowances are measured. It changes the transparency expected around the tax rate, cash taxes paid, and the jurisdictions driving those numbers.

As of May 30, 2026, calendar-year private companies are already inside the first annual period affected by ASU 2023-09. Waiting until the financial statement draft is open will create avoidable close delays. The data needed for the new disclosure often lives across the tax provision model, state apportionment files, foreign filings, payroll tax calendars, cash disbursement detail, and legal-entity charts. That is not a January-only exercise.

What Changes and When It Applies

ASU 2023-09 applies to entities subject to ASC Topic 740, Income Taxes. Public business entities apply the amendments for annual periods beginning after December 15, 2024. Entities other than public business entities apply them for annual periods beginning after December 15, 2025. For a calendar-year private company, that means the 2026 annual financial statements are the first required annual statements under the new disclosure model.

Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. The amendments are applied prospectively, although retrospective application is permitted. Companies should decide the adoption basis before drafting the footnote because prior-year comparative presentation, board packages, lender reporting, and audit timing can all be affected.

Rate Reconciliation Workstream

The rate reconciliation is the centerpiece of the change. Public business entities must present a tabular reconciliation in both percentages and reporting currency amounts, using prescribed categories and separate disclosure for reconciling items that meet the 5 percent threshold. The categories include state and local income tax, foreign tax effects, enacted tax law or rate changes, cross-border tax laws, tax credits, valuation allowance changes, nontaxable or nondeductible items, and changes in unrecognized tax benefits.

For entities other than public business entities, ASU 2023-09 does not require the same public-company table. It does require qualitative disclosure about specific categories of reconciling items and individual jurisdictions that create a significant difference between the statutory tax rate and the effective tax rate. In practice, that means the private-company footnote still needs a disciplined rate-reconciliation file, not a vague sentence that "state taxes and permanent differences changed the rate."

Income Taxes Paid Workstream

All entities must disclose annual income taxes paid, net of refunds received, disaggregated by federal or national, state, and foreign taxes. They also must disclose income taxes paid by individual jurisdiction when the net amount paid to that jurisdiction equals or exceeds 5 percent of total income taxes paid, net of refunds.

This is where close teams can get stuck. Tax provision files often track current tax expense, estimated payments, receivables, payables, and return-to-provision true-ups, but the disclosure asks for cash paid net of refunds. The proof trail needs to tie to cash disbursements, refund deposits, legal entities, filing groups, states, countries, and period cut-off. If the company has foreign withholding, state composite payments, amended-return refunds, PTE tax payments, or acquisition-related tax settlements, build the mapping before year-end.

Private-Company Disclosure Still Needs Audit Evidence

Private companies should not read "qualitative" as "unsupported." A reviewed or audited GAAP statement still needs disclosure support that can survive partner review and lender diligence. At minimum, management should be able to show the statutory-rate starting point, the current and deferred tax provision, significant permanent items, tax credits, valuation allowance changes, state and foreign drivers, and the cash-tax schedule by jurisdiction.

The new disclosure also requires annual disaggregation of income or loss from continuing operations before income tax expense between domestic and foreign, and income tax expense or benefit from continuing operations by federal or national, state, and foreign. For multi-entity groups, that means the consolidation package and tax provision workpaper need to use the same legal-entity and jurisdiction definitions.

The 2026 Readiness Calendar

Use the first half of 2026 to build the file, not just to discuss the standard. A practical calendar:

1. By June 30: identify affected entities, reporting basis, PBE status, comparative-period approach, and whether early or retrospective presentation is relevant.

2. By August 31: map jurisdictions, legal entities, estimated tax accounts, refund receivables, foreign withholding, state PTE tax accounts, and tax provision owners.

3. By October 31: run a dry close using trailing twelve-month cash tax paid, expected reconciling items, and preliminary disclosure categories.

4. Before year-end: resolve missing jurisdiction tags, unusual refunds, tax credit support, valuation allowance memos, and uncertain tax position documentation.

5. At final close: tie the disclosure to the provision, general ledger, bank activity, return-to-provision analysis, and management review sign-off.

Practical Example and Ownership Framework

Assume a venture-backed SaaS company has $30 million of revenue, $3.2 million of pretax book income, and a 21 percent U.S. federal statutory starting point. The baseline federal expected tax is $672,000. For a public-company style threshold analysis, 5 percent of that amount is $33,600. A $410,000 R&D credit, $185,000 valuation allowance release, $92,000 of state tax net of federal effect, and $58,000 foreign tax effect would not be "small" disclosure issues. They would drive the rate story investors and lenders care about.

The ownership model should be explicit. The controller owns the close calendar and GL tie-out. The tax preparer or tax advisor owns the provision model, tax law inputs, credits, uncertain tax positions, and return-to-provision analysis. The CFO owns the disclosure judgment and investor/lender messaging. The auditor or reviewing CPA evaluates whether the disclosure is complete, supportable, and consistent with ASC 740. If no one owns the jurisdiction cash-tax schedule, the footnote will become a last-minute bottleneck.

Common Mistakes

• Treating ASU 2023-09 as a tax-return issue. The disclosure is a GAAP financial reporting matter tied to ASC 740, audit evidence, and footnote transparency.

• Waiting until the annual audit starts. Cash-tax jurisdiction data often requires bank, GL, tax, and legal-entity cleanup.

• Confusing tax expense with taxes paid. The new cash-tax disclosure is based on payments net of refunds, not simply current tax expense.

• Using inconsistent jurisdiction definitions. Domestic, foreign, federal, national, state, and legal-entity labels need to align across the provision and disclosure.

• Ignoring valuation allowance and credit support. These items can materially explain the effective tax rate and should be memo-supported.

• Assuming private-company users will not care. Lenders, investors, acquirers, and boards often read tax disclosures as a signal of finance-function maturity.

Proof Notes

• FASB ASU 2023-09 states that the amendments apply to all entities subject to Topic 740 and primarily improve disclosures related to the rate reconciliation and income taxes paid. See the FASB ASU 2023-09 PDF.

• FASB's effective-date table confirms annual-period adoption for public business entities after December 15, 2024 and for other entities after December 15, 2025, with early adoption permitted for annual statements not yet issued. See FASB effective dates.

• The ASU requires annual income taxes paid, net of refunds, disaggregated by federal or national, state, and foreign taxes, plus individual jurisdictions meeting the 5 percent cash-tax threshold.

• The ASU also requires annual disaggregation of continuing-operations pretax income between domestic and foreign, and income tax expense or benefit by federal or national, state, and foreign.

The Bottom Line

ASU 2023-09 is a disclosure standard, but it is not a cosmetic footnote edit. Companies that prepare GAAP financial statements need a supportable tax provision, a cash-tax-by-jurisdiction schedule, and a management review process that explains the effective tax rate before auditors, lenders, or investors ask. For calendar-year private companies, 2026 is the adoption year. The strongest move is to build the ASC 740 disclosure file during the year, not after the draft statements are already late.
