Tax Coda Weekly Digest — February 15, 2026
This week pulled transparency into focus. Public companies began showing where cash taxes actually move. Courts tightened procedural limits around installment agreements and passport revocations. The IRS adjusted compliance timelines under SECURE 2.0. One taxpayer proved that not every side venture is a hobby under §183. And tariffs imposed under emergency authority now face unavoidable congressional votes and pending judicial review.
Airbnb 2025 cash taxes show limited geographic detail
Airbnb’s 2025 Form 10-K reflects the new requirement to disclose cash income taxes paid, but offers a limited country-level breakdown. The filing aggregates most payments without meaningful jurisdiction-by-jurisdiction clarity. While technically compliant, the disclosure leaves investors with only partial insight into geographic tax exposure.
Why It Matters:
Cash taxes paid are now a required transparency metric.
Aggregated disclosure limits risk assessment by jurisdiction.
Investors and regulators will compare levels of detail across peers.
Takeaway:
Compliance does not equal transparency when geographic detail is thin.
IRS passport ban upheld for $1.6M tax debt
Lloyd Thomas Spencer v. Commissioner
The Tax Court upheld the IRS certification of a seriously delinquent tax debt exceeding $1.6 million, allowing passport revocation procedures to stand under §7345. The taxpayer failed to show that the certification was erroneous or that statutory exceptions applied.
Why It Matters:
Reinforces the IRS’s authority to restrict passports for large unpaid debts.
Limits judicial relief absent procedural error.
Confirms passport enforcement remains an active collection leverage.
Takeaway:
Large unpaid tax debts can restrict international travel.
Court bars penalty and interest challenge after taxpayer signs installment agreement
Diego E. Salazar v. Commissioner
The Tax Court denied a taxpayer’s attempt to challenge penalties and interest after entering into an installment agreement. By agreeing to the payment plan, the taxpayer forfeited certain rights to contest underlying amounts. The Court treated the agreement as binding.
Why It Matters:
Shows installment agreements carry procedural consequences.
Limits post-agreement challenges to assessed amounts.
Reinforces the finality of collection-stage decisions.
Takeaway:
Signing an installment agreement can close the door on later disputes.
IRS extends SECURE 2.0 deadlines and revises 2025 disclosure standards
Internal Revenue Bulletin 2026-7
The IRS extended compliance deadlines under SECURE 2.0 and revised certain 2025 disclosure requirements for retirement plans. The guidance provides additional transition relief for plan sponsors as they adjust systems and documentation.
Why It Matters:
Gives employers more time to implement complex plan changes.
Reduces short-term compliance risk.
Signals continued phased rollout of SECURE 2.0 rules.
Takeaway:
Retirement plan compliance timelines remain fluid.
Tax Court allows §183 business deductions for software venture
James D. Sullivan v. Commissioner
The Tax Court allowed business deductions under §183 after finding the taxpayer’s software venture operated with a profit motive. The Court credited business plans, time commitment, and operational structure over years of losses.
Why It Matters:
Confirms profit motive analysis remains fact-intensive.
Demonstrates that sustained losses do not automatically trigger hobby classification.
Reinforces documentation and operational discipline.
Takeaway:
Losses alone do not turn a business into a hobby.
Supreme Court review could determine the future of emergency tariffs
The Supreme Court heard constitutional challenges to the tariff regime and has not yet issued a decision. The case centers on whether IEEPA permits broad tariff imposition tied to trade deficits. A ruling that narrows executive authority would undermine the legal basis for the current tariff structure. A ruling upholding it would entrench emergency-based trade policy as a durable tool.
Why It Matters:
Could redefine the scope of executive power in trade policy.
Affects the stability of tariff-dependent revenue and pricing structures.
Shapes the future use of the national emergency authority in economic policy.
Takeaway:
The durability of the current tariff regime may hinge on a single Supreme Court opinion.

Overall Takeaway
Disclosure expanded. Enforcement tools held. Procedural choices limited later arguments. Deadlines moved. Profit motive survived scrutiny when facts supported it. And tariffs imposed under emergency authority are now subject to both congressional review and constitutional review.
