The share of taxpayers using State and Local Tax (SALT) deductions has fallen sharply since 2017, when nearly a third claimed them, to less than one in ten by 2022.
From our experience, this shift reflects how the SALT deduction cap changed household decisions on whether to itemize or take the standard deduction.
With the Big Beautiful Bill Act introducing new provisions, many high earners in states with steep property or income taxes want clarity.

Understanding The Current SALT Deduction Cap
Before diving into the new rules, it’s important to understand where things started and how new rules shaped taxpayer behavior. The SALT deduction cap has been one of the most debated features of the TCJA rules, especially for those living in high tax states.
The $10,000 Deduction Cap
The Tax Cuts and Jobs Act, often called the Jobs Act, set a hard deduction cap of $10,000 on state and local tax payments. That includes local tax from property and state income tax. Many taxpayers who once itemized suddenly found their deductions slashed.
For example, a family paying $25,000 in property and state income taxes could only claim $10,000, leaving $15,000 nondeductible.
High Tax Vs Low Tax States
This cap hit many taxpayers in high property-tax states such as New York, New Jersey, and California much harder than those in states with no income tax. In places like Texas or Florida, the cap mattered less because state income taxes were minimal.
To illustrate: A homeowner in California with $20,000 in state income taxes compared to a Florida resident with only $6,000 in property taxes. One lost a major deduction, the other barely noticed a change.
Adjusted Income Thresholds
The impact also depended on adjusted gross income and modified adjusted gross income. Taxpayers with higher earnings often exceeded itemization thresholds anyway, but the cap limited their benefit.
On paper, the household income looked strong, but the inability to deduct all taxes meant their taxable income shot up. That drove higher tax liability even when earnings stayed the same.
Filing Status Matters
Another overlooked factor was filing status. Married filing jointly taxpayers got the same $10,000 cap as single taxpayers, which made dual-income households feel the pinch even more.
For example, two professionals filing jointly with $300,000 combined income could only deduct the same amount as a single filer making half as much. That inequity raised plenty of eyebrows and became a talking point for reform.
Lessons Learned
In practice, the cap reshaped how people approached deductions. Some people shifted charitable giving into bunching strategies, while others considered relocating to reduce exposure to high taxes.
Well into 2025, the SALT deduction cap continues to be a central piece of the tax conversation, setting the stage for the changes introduced in the big beautiful bill act.
The Big Beautiful Bill Act: Changes
Now that the Big Beautiful Bill Act has officially passed in July 2025, taxpayers finally have clarity. The so-called beautiful bill brings new legislation that attempts to fix frustrations created by the old $10,000 cap.
Key Provisions In The New Law
The new law allows a higher threshold amount for deductions. Depending on income thresholds, taxpayers in high tax states may see an increased cap of $20,000 for singles and a higher cap of $40,000 for joint filers.
A couple with $25,000 in state and local tax payments, for instance, will now be able to deduct nearly all of it instead of being limited to $10,000.
House Vs Senate Versions
The house bill and house version initially offered unlimited deductions, while the senate version preferred a capped approach tied to income. The final house proposal landed somewhere in the middle.
The House-passed version provides more relief than the Senate’s. After house approval, the compromise ensures more equitable benefits without blowing a hole in the budget.
Impact On Federal Revenue
The federal government faced concerns about revenue loss. To balance the books, lawmakers paired the SALT relief with modest spending cuts and a temporary increase in certain payroll taxes for high earners.
For example, those earning above $1 million in adjusted income may see an extra surtax for a few years. This design kept the package close to revenue neutral.
Connection To TCJA Permanent Rules
Some parts of the TCJA permanent framework remain. The cap structure is still tied to filing status, and phaseouts exist for very high-income filers. That means not every taxpayer will benefit equally.
For example, those making $2 million or more may find the cap still restricts them, even under the new rules.

Timeline And Updates
The changes apply to tax years beginning January 1, 2025. That means taxpayers should prepare now for filing in 2026. If you’re a homeowner with a large property tax bill, you’d do well to keep receipts handy and talk with professionals about timing payments.
These major updates mark one of the most significant tax cuts for high earners in recent years.
Strategic Tax Planning for High Income Earners
The updated rules under the Big Beautiful Bill open new opportunities for high earners to rethink their approach. Smart planning now can make a real difference in how much is saved when filing.
Optimize With Modified Adjusted Gross Income
One of the first steps is checking modified adjusted gross income (MAGI). Reducing MAGI lowers exposure to caps and phaseouts.
For example, contributing more to retirement accounts can reduce modified adjusted gross numbers, which in turn may lower taxable income. Keeping MAGI in check makes qualifying for deductions and credits much easier.
Coordinating SALT, Mortgage, And Charitable Deductions
Layering deductions is where strategy pays off. When pairing the SALT benefit with mortgage interest, a well-timed charitable deduction, or cash contributions, taxpayers can maximize their itemized deductions.
For instance, combining a large charitable gift in the same year as high property taxes can help surpass the standard deduction threshold. This way, itemizing beats taking the additional standard deduction.
Pass Through Income And Entity-Level Planning
Business owners should pay attention to pass through income. Structuring through pass through entities may allow better coordination with the SALT deduction. For example, shifting certain expenses to the entity level could lower overall taxable income.
This strategy has been valuable for real estate investors who own property under LLCs and partnerships.
Comparing Standard Vs Itemized Approaches
The new SALT cap changes make comparing itemized deductions against the standard deduction critical each year.
For example, married couples in high property-tax states may find itemizing saves thousands, while single taxpayers with lower state taxes might come out ahead using the standard option. In cases like these, running both calculations before filing is always worth the effort.
Don’t Forget Tax Credits
Even with larger deductions, a tax credit offers direct savings on liability. Credits for education expenses, energy-efficient upgrades, or certain business activities can reduce the final bill dollar for dollar.
For example, installing solar on a rental property may offset what otherwise would have been owed after deductions.
Planning For Married Vs Single Filers
Income thresholds differ for joint vs single status, so each filer type needs tailored planning.
For example, married couples making $400,000 may hit phaseouts sooner than a single taxpayer at $200,000. Adjusting a financial plan to reflect those differences ensures no tax penalty surprises down the line.
Implementation Timeline and Practical Steps
The Big Beautiful Bill SALT updates take effect in tax years beginning January 1, 2025. That means the first returns impacted will be filed in spring 2026. Knowing the timeline and steps ahead keeps surprises away.
Key Dates to Watch
Tax years starting January 2025 use the new rules.
- Mid-2025: IRS guidance clarifies calculation methods.
- April 2026: first filing deadline with changes.
Guidance for Individual Taxpayers
Individual taxpayers in high-tax states should start evaluating whether itemizing will now provide bigger benefits. For example, a homeowner in New Jersey paying $18,000 in property and state taxes will see much more relief compared to prior years.
Federal Deduction and State Law Interplay
The federal deduction interacts closely with state laws. Some states conform quickly to federal changes, while others take years.
For example, California often lags behind, which means residents there may have a different set of rules at the state level. Checking both sides avoids missed savings.
Documentation and Compliance
Your records are more important than ever. Essential compliance documentation includes:
- Property tax bills
- State income tax records
- Receipts for charitable giving
- Evidence of mortgage payments
Not keeping these records could reduce allowable deductions, so be careful!
Preparing For Sweeping Changes
The 2025 transition means adapting to new tax laws and new rules. Reviewing personal exemptions and past filing strategies will highlight areas that need adjusting.
A couple who always used the standard deduction, for example, may now need to switch. These major updates bring sweeping changes, and proactive planning prevents costly errors.
Final Thoughts
The Big Beautiful Bill has shifted the landscape for high income earners who have long felt squeezed by the old SALT deduction limits. The updates give taxpayers a fresh chance to refine a financial plan and prepare for the new tax laws that now take effect.
These aren’t just technical adjustments, though. These rules affect real money and long-term choices.
Every taxpayer’s situation looks different. That’s why seeking professional guidance is one of the smartest steps anyone can take before filing. Planning now means less stress later and more confidence when the next tax season rolls around.
