As the Senate begins final negotiations over the House-passed tax-and-spending package widely branded as Trump’s “One Big Beautiful Bill”, internal divisions inside the Republican Party are threatening to derail one of its key tax provisions: the State and Local Tax (SALT) deduction cap.
While the House version of the bill raised the SALT cap from $10,000 to $40,000, that compromise is now facing strong opposition from multiple Senate Republicans who want the cap to stay at its original 2017 level of $10,000.
This latest rift isn’t between Democrats and Republicans it’s emerging inside the GOP itself, with significant regional tensions shaping the debate.
The SALT deduction cap has been one of the most controversial parts of the Tax Cuts and Jobs Act (TCJA) of 2017. Originally designed to limit deductions for high-income taxpayers in blue states, the cap limited the ability of taxpayers to fully deduct their state income and property taxes on their federal returns.
The House’s $40,000 compromise was intended to split the difference but now faces fierce resistance in the Senate.
The SALT cap argument is now one of the final sticking points as Senate Republicans work to craft a version of the bill that can survive the budget reconciliation process.
In other words, this isn’t just a side issue. The future of the full tax-and-spending package may now hinge on resolving the SALT cap fight.
