Trump’s SALT Deduction Increase and Its Implications
In 2025, the federal limit on the state and local tax (SALT) deduction will temporarily rise from $10,000 to $40,000, a provision introduced under President Donald Trump’s tax legislation. This adjustment aims to provide enhanced tax relief for homeowners and taxpayers in states with high local tax burdens. The SALT deduction allows taxpayers who itemize to deduct state and local taxes paid, including income and property taxes, from their federal taxable income. Since the 2017 tax reforms capped this deduction at $10,000, many residents in high-tax states have faced increased federal tax liabilities.States Receiving the Largest Median SALT Savings
According to a recent analysis from Redfin, taxpayers in certain states stand to benefit disproportionately from the increased SALT deduction limit. The study estimates median savings for typical homeowners based on projected deductions and a 24% marginal tax rate applied to the amount exceeding the previous $10,000 cap.- New York: $7,092
- California: $3,995
- New Jersey: $3,897
- Massachusetts: $3,835
- Connecticut: $3,133
States with Minimal SALT Deduction Gains
- South Dakota: $1,033
- Alaska: $1,052
- Nevada: $1,090
- Tennessee: $1,097
- New Hampshire: $1,101
Policy Details and Phaseout Mechanism
The increased SALT deduction cap will begin phasing out for taxpayers with incomes exceeding $500,000, a threshold that will rise by 1% annually until 2029. Unless extended, the cap will revert to $10,000 starting in 2030. Importantly, only taxpayers who itemize deductions, rather than taking the standard deduction, are eligible for SALT benefits. As of 2022, approximately 10% of filers itemized, predominantly higher-income individuals.Methodology and Limitations of the Analysis
Redfin’s estimates are based on simulations incorporating average property values and state income tax rates. However, these calculations exclude local income taxes, which can vary significantly within states, and rely on assumptions that may not capture the full complexity of individual tax situations.Additional Insights from the Bipartisan Policy Center
A May 2025 report from the Bipartisan Policy Center complements these findings by examining the distribution of SALT claimants and average deductions. Their data indicates that states like Connecticut, New York, New Jersey, California, and Massachusetts have average SALT deductions near the $10,000 cap, emphasizing the cap’s constraining effect. Conversely, states such as Wyoming, Tennessee, Nevada, North Dakota, and South Dakota exhibit much lower average deductions, consistent with the smaller benefits observed in those regions.FinOracleAI — Market View
The temporary increase in the SALT deduction limit to $40,000 for 2025 represents a significant fiscal reprieve for taxpayers in states with high local tax burdens. The adjustment primarily benefits higher-income taxpayers who itemize deductions, reinforcing the regional disparities in federal tax relief.- Opportunities: Increased after-tax income for homeowners in high-tax states may stimulate local economies and housing markets.
- Risks: The phased reduction and eventual reversion to the $10,000 cap in 2030 could create uncertainty for taxpayers and real estate markets.
- Potential for increased state-level budget pressures due to reduced federal tax offsets.
- Taxpayers in low-tax states see minimal benefit, preserving existing regional tax disparities.
Impact: The raised SALT deduction cap is a positive development for taxpayers in high-tax states, easing federal tax burdens in the short term while highlighting ongoing regional tax policy challenges.
