State and Local Tax Deductions (SALT): Navigating Changes and Limits with AI and Automation


The landscape of state and local tax deductions (SALT) has experienced significant shifts, particularly following the enactment of the Tax Cuts and Jobs Act (TCJA) in 2017, which capped the SALT deduction at $10,000. This cap has stirred debate and caused significant changes in tax filing strategies, particularly in high-tax states. As we move forward, understanding these changes and exploring how artificial intelligence (AI) and automation can streamline the process is essential for taxpayers and professionals alike.

Understanding SALT Deduction Changes

The SALT deduction allows taxpayers to deduct local tax payments on their federal tax returns. Before the TCJA, there was no cap, meaning that taxpayers could deduct an unlimited amount for state and local property taxes, and either income or sales taxes. The $10,000 cap significantly affects those in states with higher tax rates, such as New York, New Jersey, and California, where many taxpayers now find themselves paying higher federal taxes.

Legislative Responses and Updates

In response to the cap, some states have implemented or are considering "workarounds." For example, states like New Jersey and Connecticut have established charitable funds that taxpayers can contribute to in exchange for a tax credit. These contributions can then potentially be written off as charitable donations for federal tax purposes, albeit this strategy has faced scrutiny from the IRS.

Looking ahead, discussions continue in Congress about adjusting or eliminating the cap, especially with shifts in political power and ongoing debates about tax fairness. Taxpayers and advisors must stay informed about these legislative dynamics as they can significantly impact tax strategies.

The Role of AI and Automation

AI and automation are poised to revolutionize how taxpayers manage SALT deductions amid these changes. Here’s how technology is making a difference:

  1. Error Reduction: AI can analyze tax returns to identify common errors or inconsistencies, particularly in how deductions are claimed. This minimizes the risk of audits and penalties associated with misreporting.

  2. Scenario Simulation: Advanced software can simulate various tax scenarios under different legislative landscapes to find the most advantageous strategies for taxpayers, taking into account the cap on SALT deductions.

  3. Regulatory Updates: AI-driven systems can be updated in real-time to reflect changes in legislation, ensuring that taxpayers and advisors are always working with the latest tax rules and regulations.

  4. Enhanced Record-Keeping: Automation tools help in maintaining detailed records of deductions, including state and local taxes paid. This is crucial for ensuring compliance and for supporting tax positions if audited.

  5. Advisory Services: AI can power virtual tax advisors that provide personalized advice based on individual financial situations and how changes to the SALT deduction may impact them.


As the debate around the SALT deduction cap continues, leveraging AI and automation can help taxpayers navigate this complex landscape more effectively. By enhancing accuracy, ensuring compliance, and providing up-to-date advisory services, technology not only simplifies the tax filing process but also optimizes it, ensuring that taxpayers can make the most of their deductions.
