District Court Refuses to Shake Up SALT Cap

Why It Matters

The court’s decision keeps the $10,000 SALT limit in place, preserving the status quo for most taxpayers, while the OBBBA’s temporary increase offers relief to high‑tax filers but adds complexity for high‑income earners. Advisors must navigate both the new cap and emerging workarounds to optimize client tax positions.

Key Takeaways

• District court dismisses constitutional challenge to $10k SALT cap.
• OBBBA raises SALT deduction limit to $40k starting 2025.
• Phase‑out reduces cap for incomes above $500k, increasing annually.
• Pass‑through entity workarounds let some owners sidestep SALT cap.
• High‑tax states see more taxpayers revert to itemizing deductions.

Pulse Analysis

The Supreme Court’s recent rulings have left the $10,000 SALT deduction cap untouched, reinforcing the Tax Cuts and Jobs Act’s intent to limit itemized deductions for high‑tax states. This judicial stance underscores the difficulty of overturning tax policy through constitutional arguments, prompting taxpayers and advisors to seek alternative compliance strategies. The decision also signals that any future legislative changes will likely need to navigate a complex legal landscape rather than rely on court challenges.

Enter the One Big Beautiful Bill Act, a bipartisan effort that temporarily lifts the SALT cap to $40,000 beginning in 2025. While the increase promises substantial tax relief for residents of high‑tax jurisdictions, the act couples it with a phase‑out mechanism that reduces the benefit for filers whose modified adjusted gross income exceeds $500,000. This nuanced design aims to balance broader middle‑class relief with revenue considerations, but it also creates a tiered impact where affluent taxpayers may see marginal or even negative gains.

For practitioners, the key takeaway is the growing relevance of state‑level workarounds, especially for owners of pass‑through entities such as partnerships, S‑corporations, and LLCs. By routing SALT payments through the entity, owners can claim a deduction or credit on their personal returns, effectively sidestepping the federal cap. Advisors should proactively assess eligibility, monitor state legislative updates, and implement these structures before year‑end to maximize client savings while remaining compliant with evolving tax law.
