IRS Issues Favorable CAMT Guidance — What Finance Teams Need to Know

The corporate minimum tax just got a little less painful — but only if you act on it.

The IRS recently released Notice 2026-7, providing additional interpretive guidance on the Corporate Alternative Minimum Tax (CAMT) — one of the more complex provisions in the current tax landscape for larger businesses. While many smaller retail and CPG operators fall below the CAMT’s applicability thresholds, larger groups and businesses backed by private equity should be reviewing the guidance closely and reassessing their current projections.

As a brief refresher, the CAMT imposes a 15% minimum tax based on adjusted financial statement income (AFSI) — meaning it is calculated from GAAP book income rather than traditional taxable income. This created significant concern among finance teams because timing differences between financial statement treatment and tax treatment for capitalized costs, depreciation, and certain transactions could produce AFSI figures substantially higher than taxable income.

Notice 2026-7 is broadly viewed as favorable for taxpayers. The guidance expands the scope of permitted adjustments to AFSI and reduces certain scenarios where standard GAAP accounting treatment would unintentionally inflate minimum tax exposure. Specifically, the notice addresses the treatment of capitalized costs, transactions involving financially distressed companies, foreign asset transfers, and partnership investment calculations.

For retail and CPG operators with significant inventory balances, fixed assets, or international operations, these adjustments may meaningfully reduce projected CAMT exposure relative to earlier interpretations of the law. Controllers and tax directors should revisit their deferred tax models and CAMT calculations in light of the new guidance, and companies preparing second-quarter estimates should ensure finance and tax teams are aligned on revised assumptions before those estimates are finalized.

Bottom Line: The new IRS guidance may reduce CAMT exposure for some organizations, but the calculations are complex — updated projections and provision models are warranted now.
