The debate over the state and local tax (SALT) deduction is back in the spotlight, particularly concerning its implications for California homeowners. With the current $10,000 cap set to expire, discussions in the U.S. House and Senate are focused on whether to raise or maintain the limit. This decision carries significant weight for many Californians, especially those in high-cost areas.
The crux of the debate centers on a Republican tax provision that impacts what high-income Californians can deduct on their taxes. Established in 2017 during President Donald Trump’s term, the $10,000 SALT deduction cap limited the ability of California taxpayers to deduct their full state and local income and property taxes. Now, the House proposes raising the cap to $40,000, while the Senate aims to keep it at the existing level.
This article breaks down the core arguments, analyzes the potential winners and losers, and explores what this all means for the California economy. From the “working rich” to small business owners, understanding the SALT deduction debate is essential for navigating the evolving tax landscape.
Understanding the SALT Deduction
The SALT deduction allows taxpayers who itemize to deduct state and local taxes from their federal income tax. These taxes include property taxes, income taxes (or sales taxes), and other local levies. Prior to the 2017 tax law, there was no limit on the amount that could be deducted. However, the 2017 Tax Cuts and Jobs Act imposed a $10,000 cap, significantly affecting taxpayers in states with high state and local taxes, such as California.
The implementation of the $10,000 cap was intended to help offset the costs of corporate tax cuts included in the 2017 bill. For California, this change meant that many residents, particularly those in wealthier areas, could no longer deduct the full amount of their state and local taxes, increasing their federal tax burden.
According to IRS data, approximately 2.8 million California taxpayers claimed the SALT deduction in 2022, representing about 15% of all filers in the state. The highest percentage of those claiming the deduction resided in affluent counties like Marin, Santa Clara, and San Mateo. This underscores how crucial the SALT deduction is for specific regions within California.
The House Proposal: Raising the SALT Cap
The U.S. House of Representatives has proposed raising the SALT deduction cap to $40,000. This proposition is championed by several representatives who argue that it will provide much-needed tax relief to middle- and upper-middle-class families in high-tax states. Proponents of the increase suggest it will stimulate the economy by allowing households to retain more of their income.
However, this proposal isn’t without its critics. Many experts argue that raising the cap disproportionately benefits wealthy individuals who don’t necessarily need another tax break. Nikhita Airi, a research associate at the Urban-Brookings Tax Policy Center, noted that raising the cap would be expensive and deliver minimal benefits to most taxpayers nationally. She estimates that only about 10% of taxpayers who itemize use the SALT deduction.
Despite these criticisms, some argue that in high-cost states like California, the increased cap would provide substantial relief to the “working rich”—those with annual incomes between $250,000 and just under $500,000. Dennis Ventry, a professor at UC Davis School of Law, points out that these individuals are likely to itemize their deductions and could see significant savings.
The Senate’s Position: Keeping the Cap at $10,000
In contrast to the House, the U.S. Senate is inclined to maintain the SALT deduction cap at $10,000. This position reflects concerns about the potential costs of raising the cap and the perception that it primarily benefits the wealthy. With no Republican senator representing a high-tax state, there is little incentive to push for an increase.
Alan Auerbach, a professor of economics and law at UC Berkeley, explains that the Senate’s stance is largely driven by the absence of political pressure from high-tax states. He suggests that if the Senate had a choice, they would likely avoid including the SALT deduction provision altogether.
Maintaining the $10,000 cap would mean that many California taxpayers continue to face a higher federal tax burden, particularly those with high property taxes and state income taxes. This could impact their financial planning and investment decisions.
Impact on California Taxpayers
For California, the SALT deduction debate is especially critical due to the state’s high cost of living and elevated tax rates. Raising the cap could allow many residents to deduct the full cost of their property taxes, which can be substantial. For instance, the median price of a home in California is $900,000, resulting in approximately $9,000 in annual property taxes. An increased deduction cap would enable many homeowners to deduct these taxes along with other state and local taxes.
Dennis Ventry notes that this could free up funds for other essential expenses, such as child care, enabling more spouses to re-enter the workforce. The House proposal suggests that the increased cap would apply to those with annual incomes of $500,000 or less, while taxpayers earning more would remain subject to the $10,000 cap.
However, experts caution that the benefits would largely accrue to higher-income earners. While some argue it helps the “working rich,” the reality is that the majority of California taxpayers would see little to no direct benefit. This raises questions about the equity of the proposed tax changes.
The Workaround and Its Potential Elimination
Another crucial aspect of the proposed tax bills is the potential elimination of certain workarounds that taxpayers have been using to circumvent the SALT deduction cap. One common method involves paying state taxes through a business entity, allowing owners to deduct these taxes against their personal state income taxes.
If these workarounds are eliminated, individuals and small businesses with incomes under $500,000—such as doctors with private practices, lawyers, or financial professionals with their own firms—could be subject to the deduction cap. However, a Tax Law Center analysis at New York University School of Law pointed out that the House bill includes exceptions, depending on the types of taxes being paid.
Darien Shanske, a professor at UC Davis School of Law, notes that these tax proposals can be complex and challenging to interpret. Eliminating the cap workaround, for example, might be more palatable if the funds were used to support public services like universal pre-K. Instead, he argues, it appears to be a measure to retain low taxes on large corporations, which could disproportionately affect smaller businesses.
Political Considerations and Future Outlook
More than 20 California Democrats in the House, including U.S. Reps. Dave Min, Zoe Lofgren, and Mike Thompson, have advocated for the complete removal of the SALT deduction cap. In a letter to House leaders, they argued that California taxpayers pay more than their fair share of taxes and deserve relief during these challenging economic times.
Rep. Young Kim, a Republican member of Congress representing parts of Orange, Riverside, and San Bernardino counties, has pushed for a $62,000 deduction limit. This stance reflects the concerns of constituents in high-cost areas where almost half of the homes are valued at $1 million or more.
Ultimately, the fate of the SALT deduction cap lies in the hands of Congress, and the outcome will significantly impact California taxpayers. Whether the cap is raised, maintained, or eliminated, the decision will have far-reaching consequences for the state’s economy and the financial well-being of its residents.
Final Thoughts on the SALT Deduction Debate
The SALT deduction debate is a complex issue with varied impacts on California taxpayers. While raising the cap could provide relief to some middle- and upper-middle-class families, critics argue that it primarily benefits the wealthy. The Senate’s reluctance to increase the cap reflects concerns about fiscal responsibility and equity.
For California homeowners and small business owners, understanding the potential changes to the SALT deduction is crucial for effective financial planning. Monitoring the progress of tax legislation and seeking professional advice can help navigate the evolving tax landscape.
As Congress continues to grapple with these issues, the future of the SALT deduction remains uncertain. The outcome will undoubtedly shape the financial future of many Californians and influence the state’s economic trajectory.
