When congress passed the Tax Cuts and Jobs Act (TCJA) in December 2017, it redefined how Americans paid taxes. It lowered tax rates, expanded deductions and rewrote decades of policy. But many of those provisions were set to expire at the end of 2025.

Now, a new law has entered the scene: the One Big Beautiful Bill Act (OBBBA). Positioned as both a continuation and a correction, it redefines what the post-TCJA tax world looks like.

The TCJA laid the groundwork for lower taxes and broader deductions, but its short timelines created uncertainty. The OBBBA seeks to make several of those popular provisions permanent while introducing new relief for workers, seniors and small business owners.

How the Big Beautiful Bill Builds on the TCJA

Expanded Standard Deduction
The TCJA nearly doubled the standard deduction and increased the child tax credit. The OBBBA preserves and expands these increases.

• For tax year 2025, the standard deduction rises to $15,750 for single taxpayers, $31,500 for married couples filing jointly and $23,625 for head of households.
• For tax year 2026, the standard deduction increases again to $16,100 for single taxpayers, $32,200 for married couples filing jointly and $24,150 for head of households.

No Tax on Tips – Effective 2025-2028 (IRS, 2025)
Building on the TCJA’s pro-wage approach, the OBBBA allows deductions for qualified tip income, defined as voluntary cash or charged tips received directly from customers or through tip sharing. The maximum annual deduction is $25,000. Or, if self-employed, an individual’s net income.

No Tax on Overtime – Effective 2025-2028  (IRS, 2025)
Individuals who receive overtime compensation may now deduct the portion of the pay that exceeds their regular rate. The maximum annual deduction is $12,500 for single filers, or $25,000 for joint filers.

Vehicle Loan Interest Deduction – Effective 2025-2028  (IRS, 2025)
This fresh addition allows taxpayers to deduct up to $10,000 in annual interest on qualified vehicles for personal-use vehicles. To qualify, the loan must:

• Originate after December 31, 2024
• Be used to purchase a new vehicle that was assembled in the US (used vehicles do not qualify)
• Apply to a personal use vehicle (not business or commercial)
• Be secured by a lien on the vehicle

Temporary SALT Cap Relief – Effective 2025-2029  (IRS, 2025)
The TCJA capped the state and local tax deduction at $10,000, but the OBBBA temporarily raises that cap to as much as $40,000

Senior Tax Relief “Bonus” – Effective 2025-2028 (IRS, 2025)
The law introduces an additional deduction for taxpayers aged 65 and older, on top of the current additional standard deduction for seniors. The benefit applies to both itemizing and non-itemizing taxpayers and provides up to $6,000 for single filers, and $12,000 for married couples where both spouses qualify.

A Turning Point for Taxpayers

Tax year 2025 is more than just another filing year…it’s a pivot point in tax history. The TCJA reshaped the tax landscape by delivering immediate relief for taxpayers but left lasting questions about what would follow. The Big Beautiful Bill refines that model through the continuation of key benefits, the expansion of targeted deductions and the introduction of entirely new opportunities.

Together, they form a two-chapter story in modern tax policy. One that begins with sweeping reform and continues with strategic recalibration. As these updates take effect, proactive planning becomes essential. Now is the time to schedule your year-end tax review with your accountant to identify opportunities and make the most of the 2025 changes before the new year begins.
