Key Changes and Effective Dates

Major provisions include:

• Making current tax rates permanent (see table below)
• Enhancing the Child Tax Credit to $2,200 per child, indexed for inflation
• Temporarily increasing the State and Local Tax (SALT) deduction cap to $40,000 for 2025, with annual increases through 2029, then reverting to $10,000 in 2030 (cap phases down for high-income taxpayers)
• New, temporary deductions for tip and overtime income (2025–2028)
• Creation of “Trump Accounts” for newborns ($1,000 per eligible child; details to be set by the Treasury)
• A special $6,000 additional deduction for taxpayers age 65 and older (2025–2028, with phaseouts at higher income levels)
• Making mortgage insurance premiums permanently deductible
• Making permanent the 20% Qualified Business Income (QBI) deduction for pass-through entities
• Increasing the estate and gift tax exemption to $15 million per person (indexed for inflation) for deaths in 2026 and after
• Rolling back most green energy credits after 2025
• Most provisions are effective for tax years beginning January 1, 2025

Who Will Be Most Affected

• Middle- and upper-middle-income households: Stand to benefit from higher standard deductions, enhanced child tax credits, new deductions for tips/overtime, and a higher SALT cap (phased down at higher incomes).
• Seniors (65+): Receive an extra $6,000 deduction (2025–2028), phased out at higher incomes.
• Residents of high-tax states: Temporarily benefit from a much higher SALT cap.
• High-income households: May see SALT cap phased down and some deductions limited.
• Small business owners: Benefit from permanent QBI deduction and new/expanded expensing rules.
• Green energy investors/homeowners: Lose access to most credits after 2025.

Historical Context and Comparison to Previous Tax Laws

This bill represents an extension and expansion of the 2017 Tax Cuts and Jobs Act (TCJA). The Congressional Budget Office projects that, compared to “current law,” the new tax bill will have a multi-trillion-dollar fiscal impact, largely by extending or expanding existing policy. The Act is funded in part by eliminating green energy credits and some other program changes.

The corporate tax rate remains at 21%; there is no new progressive rate or base broadening.

Deductions for Business Owners

• Qualified Business Income (QBI) deduction: The 20% deduction for pass-through income is made permanent and expanded.
• Bonus Depreciation: 100% bonus depreciation is now permanent for property acquired after January 19, 2025.
• Section 179 Expensing: Limits are increased.
• Research & Experimental (R&E) Deductions: Domestic R&E expenses are fully deductible after 2024, with small businesses allowed to retroactively claim the deduction to 2022.

International Tax Provisions

• FDII and GILTI: Updated rates and rules; base erosion minimum tax set at 10.5% after 2025.

• Exemption increases to $15 million per individual (indexed for inflation) for deaths in 2026 and after.
• Generation-skipping transfer (GST) exemption: Now matches the estate tax exemption.
• No change to step-up in basis rules for inherited property.
• Standard deduction for seniors (age 65+): $6,000 additional deduction (2025–2028).

Planning Strategies Under the New Law

With these new exemption limits in place, high-net-worth individuals should consider several planning strategies:

1. Lifetime Gifting – The increased exemption encourages making substantial lifetime gifts to reduce the overall taxable estate.

2. Dynasty Trusts – Establishing dynasty trusts has become more advantageous, allowing wealth to be preserved and protected across multiple generations.

3. Trust Income Tax Planning – The OBBBA maintains the TCJA-era income tax brackets for trusts, providing certainty for trustees managing irrevocable trusts.

4. SALT Deduction Considerations – Despite hopes for change, the $10,000 cap on State and Local Tax (SALT) deductions remains in place, requiring residents of high-tax states to explore alternative strategies.

5. Art and Collectibles Management – Proper governance and liquidity planning for valuable collections are essential components of comprehensive estate planning under the new law.

Timeline for Implementation

The implementation of these estate and gift tax revisions follows a clear timeline:

• The OBBBA was passed by both the Senate and House in early July 2025.

• The new $15 million individual exemption ($30 million for couples) takes effect immediately.

• Inflation indexing for these exemptions will begin in 2026.

• The permanent increases to the standard deduction for seniors are also effective immediately.

It’s worth noting that the Republican tax reform efforts aimed to have this legislation passed by July 4th, 2025, and they successfully met this target. These changes represent a continuation and enhancement of the Tax Cuts and Jobs Act provisions that were set to expire.

With these estate and gift tax revisions now clearly outlined, let’s turn our attention to the practical steps individuals and families should take when preparing for these changes and how to optimize their financial planning in response to the new tax landscape.

Now that we have covered the Estate and Gift Tax Revisions, it’s crucial to focus on how to effectively prepare for these significant tax changes. With the new tax bill introducing numerous modifications, taking proactive steps will help ensure you’re well-positioned to optimize your tax situation.
