The GOP tax bill's state and local tax (SALT) deduction exchange has been a contentious issue. This change allowed taxpayers to deduct up to $10,000 in state and local taxes, but only if they gave up their ability to deduct mortgage interest.
The SALT deduction exchange was a trade-off for many taxpayers, especially those in high-tax states. By giving up mortgage interest, taxpayers could deduct more of their state and local taxes.
The impact of this change was felt most by taxpayers in states like California, New York, and New Jersey, where property values are high and state taxes are steep. These taxpayers often saw their tax bills increase as a result of the SALT deduction exchange.
As a result of the SALT deduction exchange, many taxpayers were forced to choose between deducting their state and local taxes or their mortgage interest.

Tax Bill Updates
The Tax Cuts and Jobs Act (TCJA) brought sweeping changes to the tax code, but one thing remains the same: pass-through entity tax elections still make sense.
The OB3 SALT cap increase is a key provision of the TCJA that affects how businesses calculate their state and local tax (SALT) deductions.
Businesses with pass-through entities can still benefit from making pass-through entity tax elections, even with the new SALT cap limits.
The TCJA's changes to the tax code have left many business owners wondering if making a pass-through entity tax election is still worth it.
However, with careful planning and consideration, businesses can still achieve significant tax savings by making these elections.

Tax Deduction and Cap
The proposed changes to the State and Local Tax (SALT) deduction in the GOP tax bill have been a topic of much debate. One of the key aspects of the bill is the cap on the SALT deduction, which would be set at $10,000 for individuals and $20,000 for joint filers, but the House bill proposal suggests a $30,000 cap with certain limits.
The current policy has no cap on the SALT deduction, resulting in a revenue loss of $981.2 billion from 2025 to 2034. In contrast, the House bill proposal would limit the SALT deduction to $30,000, resulting in a revenue loss of $807.2 billion during the same period.

The proposed SALT deduction caps would also have varying effects on different income percentiles. For example, the $30,000 cap would have a negligible effect on the 0-20% income percentile, but would result in a revenue loss of -0.9% for the 80-100% income percentile.

Republicans Clash Over Tax Deduction Extension
Republicans are at odds over extending a tax deduction that benefits many businesses. This deduction, known as the OB3 SALT Cap, was a key provision in the Tax Cuts and Jobs Act.

The TCJA brought sweeping changes to the tax code, including the introduction of this deduction. This cap was put in place to limit the amount of state and local taxes that can be deducted.
Many businesses, especially those in high-tax states, rely heavily on this deduction to reduce their tax liability. The cap has been a contentious issue, with some arguing it disproportionately affects certain industries and regions.
The OB3 SALT Cap Increase is a proposed solution to this problem, but it's unclear whether it will be passed. The Tax Cuts and Jobs Act brought significant changes to the tax code, and this deduction is just one of many provisions that are still being debated.

A $30,000 SALT cap with limits for those earning over $400,000 and partial closure for pass-through workarounds, as proposed in the House bill, is estimated to generate $807.2 billion in revenue over the same period.
In contrast, a $40,000 SALT cap with limits for those earning over $500,000 and partial closure for pass-through workarounds is projected to generate $659.8 billion in revenue over the 2025-2034 period.
