Calculate Your Gain Under the New SALT Cap

Published: | Updated:

The state and local tax deduction, a write-off that primarily benefits higher-income Americans living in high-tax areas, was one of the most disputed provisions of Trump’s tax-and-spend bill.

Answer five simple questions about your taxes to see your estimated gain from an increased SALT deduction.

A higher SALT cap overwhelmingly benefits more affluent Americans. For instance, a married couple in Washington, DC is unlikely to receive any money back if their income is below $200,000.

The lopsided benefits of a bigger SALT write-off made it one of the most contentious pieces of Trump’s budget bill. The gains disproportionately go to wealthy residents of blue states, where state and local taxes tend to be higher. This made the increased cap unpopular to most Republicans.

But in a tight House where few votes can be spared, a handful of Republicans from swing districts in New York, New Jersey and California staked their support of the bill on a higher deduction for state and local taxes. The House bill set the SALT deduction limit at $40,000.

After extended debate, the Senate largely kept the House’s changes to SALT intact for the final version of the bill. While the House set the SALT cap permanently at $40,000, the Senate only extended the higher deduction for five years. After that the write-off reverts back to $10,000.
