This article is part of a series detailing meaningful proposed tax law changes that could have far-reaching implications for individual income and estate taxpayers. Read the previous article on key business tax proposals.
The United States Senate is currently negotiating and drafting tax reform legislation as a follow-on to the House of Representatives ‘One Big Beautiful Bill Act’ (OBBBA), which passed the House in late May. The House-passed legislation contains meaningful tax reforms with potentially significant impact on individual income and estate taxes.
Increased lifetime gift and estate tax exemption
The OBBBA proposes significant changes to the lifetime exemption for gift and estate tax purposes.
Increased exemption: Under current law, the lifetime gift/estate tax exemption is scheduled to revert to its pre-2018 amount of $5 million for individuals and $10 million for married couples (indexed for inflation). The OBBBA proposes to increase the lifetime exemption to $15 million for individuals, or $30 million for married couples, indexed for inflation. Permanency: The OBBBA proposes to make the lifetime exemption permanent. Historically, the exemption amount has been temporary.
Tax planning: The proposed change to the gift/estate lifetime exemption makes now an ideal time for you and your family to consider what strategies to execute for your unique situation. There are several estate planning tools and strategies to consider to ensure tax efficiency. The Intentionally Defective Grantor Trust (IDGT) is one example. When drafted correctly, this type of trust is designed so that its assets are excluded from your taxable estate, yet you – as the grantor – are responsible for paying the income tax on the trust’s earnings. The IDGT offers a powerful dual benefit. First, trust assets grow free of income tax and defer estate taxes, allowing compounding appreciation to work more effectively over time. Second, when the grantor pays income tax from personal assets that are within their taxable estate, it further reduces the grantor’s taxable estate on a dollar-for-dollar basis, maximizing the overall wealth transferred to heirs. This payment of income taxes functions implicitly as an indirect gift to the trust yet does not reduce the grantor’s lifetime exemption amount.
State-level taxes are also a key consideration for gift and estate tax planning as states have widely varying gift/estate tax laws. As tax reform takes shape federally, state legislatures may reform their laws in response to the federal tax law changes, making planning important beyond the federal tax implications.
Itemized deductions
New limitation for highest tax bracket: Taxpayers in the 37% income tax bracket will be subject to a new limitation of overall itemized deductions beginning with tax year 2025. The limitation is 2/37 of the lesser of total itemized deductions or taxable income.
Increased State and Local (SALT) deduction cap: Current law imposes a maximum state and local itemized deduction of $10,000. The OBBBA proposes to increase this limit to $40,000 (for married filing joint taxpayers) beginning in 2025. The increased limit would be phased out for taxpayers with incomes over $500,000.
Notably, the Senate Finance Committee's draft of the budget reconciliation bill, released on June 16, 2025, keeps the $10,000 SALT cap in place. The Senate Finance Committee noted there is an expectation the SALT cap will be subject to further negotiations that may change the Finance Committee cap in the version of the budget bill that is voted on by the full Senate.
Auto loan interest deduction and 1099 reporting
The OBBBA also introduces a temporary auto loan interest deduction and new reporting requirements.
New tax break: For tax years 2025 through 2028, individuals may deduct up to $10,000 in auto loan interest for personal-use vehicles assembled in the US. This applies to itemizers and non-itemizers.
Eligibility: Applies to personal-use cars, minivans, SUVs, pickup trucks, motorcycles, and recreational towable units.
Phaseout: The deduction phases out for single filers with AGI over $100,000 and joint filers over $200,000.
New IRS Reporting (Section 6050AA): Effective January 1, 2025, lenders receiving $600 or more in interest on qualifying auto loans must issue Form 1099-INT to the IRS and the borrower. This applies to personal-use, US-assembled vehicles. This rule enhances tax compliance by ensuring accurate documentation.
This provision aims to ease vehicle ownership costs and support US manufacturing.
