For years, taxpayers in high-tax states felt the sting of the $10,000 cap on State and Local Tax (SALT) deductions. This limit often resulted in double taxation for business owners and high-income earners who paid far more in state income and property taxes than they could actually deduct on their federal returns.
The landscape has changed significantly with the passage of the One Big Beautiful Bill Act (OBBBA). For the 2026 tax year, the federal SALT deduction limit has increased to $40,400. This shift offers a substantial opportunity to lower your federal taxable income and keep more cash flowing through your business.
Understanding the 2026 SALT increase
The OBBBA raised the SALT cap from $10,000 to $40,000 in 2025, and that limit is indexed for inflation, rising to $40,400 for 2026. This higher ceiling applies to the total of your state and local income taxes (or sales taxes) plus your property taxes.
While this is a major win for many, it is important to note the phase-out rules. The full $40,400 deduction is available to those with a modified adjusted gross income (MAGI) of $505,000 or less ($252,500 for married individuals filing separately). If your income exceeds these thresholds, the deduction gradually scales back, though it will never drop below the original $10,000 floor.
Strategic advantages for high-tax states
If your business operates in states like California, New York, or New Jersey, you are likely intimately familiar with high state tax rates. The new $40,400 limit allows you to finally align your federal deductions more closely with your actual tax reality.
- Immediate cash flow impact. By quadrupling the potential deduction, many business owners will see a direct reduction in their federal tax liability. This translates to lower quarterly estimated payments and more working capital available to reinvest in operations or payroll.
- Itemizing becomes more attractive. With a $40,400 SALT limit, many taxpayers who previously relied on the standard deduction may find that itemizing on Schedule A now yields much higher savings. When combined with mortgage interest and charitable contributions, the total deduction can far exceed the standard amount.
- Pass-Through Entity Tax (PTET) synergy. Most high-tax states have enacted PTET workarounds that allow S-corps and partnerships to pay state taxes at the entity level. The OBBBA preserved these workarounds, meaning you may still be able to deduct state taxes as a business expense while using your individual SALT cap for personal property taxes.
Planning for the 2026 tax year
Maximizing this new limit requires more than just waiting for tax season. You should review your property tax payment schedules and state estimated tax payments now. In some cases, accelerating a payment into the current year can help you hit that $40,400 ceiling and maximize your federal benefit.
Navigating these thresholds while managing a business can be a balancing act. Ensuring you are taking the right deductions without triggering an unnecessary phase-out requires a proactive approach to your financial strategy.
