## Context: SALT Cap Change in OBBBA
Under the One Big Beautiful Bill Act (signed July 4, 2025), the State & Local Tax (SALT) deduction cap remains at **$10,000** from 2018 until 2025, but for 2026 it’s bumped to approximately **$40,400** ($20,200 married filing separately).([tscpatax.com](https://tscpatax.com/articles/salt-deduction-cap-2026?utm_source=openai))
The phase-out still applies for high-income taxpayers, and many OBBBA provisions are set to sunset in 2030.([tscpatax.com](https://tscpatax.com/articles/salt-deduction-cap-2026?utm_source=openai))
## Meet “Case: Sarah in New York”
- **Profile:** Married filing jointly, incomes jointly $800,000, property taxes and state & local taxes ~$60,000/year.
- **Pre-2026 situation:** Can deduct only $10,000 SALT, so $50,000 in state/local taxes did *not* yield any federal deduction.
- **In 2026:** With $40,400 cap, Sarah can now deduct $40,400, reclaiming $30,400 from prior years (but only starting in 2026).
- **Tax savings impact:** Suppose Sarah’s marginal federal bracket is 32%; that extra $30,400 federal deduction could mean ~$9,700 saved in federal tax for 2026.
## Strategic Moves Sarah Should Consider
- **Itemize deductions in 2026 if SALT + other deductions exceed standard deduction.** Those in New York with high property and income taxes may benefit more by itemizing.
- **Prepay SALT or state income taxes late in the year**, if able, to push deductions into taxable year 2026. But check state laws—some may not allow prepayments or have effects on state tax returns.
- **Check phase-outs:** For incomes above certain levels, the SALT deduction benefit diminishes. Use tax software to simulate phases at AGI levels above $750,000 to see if your benefit is reduced.
## Broader Lessons and Business Entity Considerations
- **Pass-through entity state tax elections (PTETs):** Some states allow a pass-through entity to pay state taxes at the entity level, enabling the entity to deduct the taxes through PTET programs regardless of SALT cap. This strategy works especially well for LLCs, partnerships, and S-corps in high-tax states.
- **Donate to charity / contribute to qualified accounts:** When trying to surpass the standard deduction and benefit from itemizing, increase charitable giving, HSAs, or other deductible contributions.
## Outcome & Trade-Offs
By deploying SALT strategies and itemizing, Sarah in New York turns losses into gains. But trade-offs include complexity of planning, potential cash-flow constraints, and risk that state tax laws or SALT phase-outs blunt the benefit. Still, for high-income individuals in high-tax states, the 2026 increase offers *meaningful opportunity* to reclaim federal deductions.
