Tax Strategy Under the One Big Beautiful Bill: Specific Planning Moves Now That TCJA Is Permanent

The enactment of the One Big Beautiful Bill Act in 2025 fundamentally changed the long-term tax planning landscape. Strategies that had been built around the impending TCJA sunset must now be recalibrated for a permanent extension. New deductions introduced by OBBB — for tips, overtime, auto loan interest, and senior taxpayers — create fresh planning opportunities. And retroactive provisions for Section 174 R&D and bonus depreciation create immediate refund opportunities for previously affected taxpayers.

Recalibrating Roth Conversion Strategy

Pre-OBBB, Roth conversions were urgent because of the impending 2026 marginal rate increases (22%→25%, 24%→28%, 32%→33%, 37%→39.6%). With OBBB making the lower rates permanent:

What changes:

• Conversion urgency for "rate arbitrage before sunset" is reduced.

• The window for converting at current rates is now indefinite.

• Multi-year conversion strategies have more time to execute.

What stays the same:

• Bracket arbitrage in low-income years (early retirement, sabbaticals) remains valuable.

• RMD elimination through Roth conversion remains a long-term planning priority.

• Estate planning benefits (Roth IRAs to heirs are tax-free under SECURE Act 10-year rule) continue.

• Future legislative changes remain possible — making opportunistic conversions in low-rate years still strategic.

The new optimal: continue systematic Roth conversions in low-income years, but without the "must execute before 2026" pressure that was driving urgency.

Estate Planning Recalibration

The pre-OBBB urgency to execute SLATs, GRATs, and dynasty trusts before the 2026 estate exemption cliff is significantly reduced:

What changes:

• The $14M per-person exemption ($28M per couple) is now permanent.

• The frantic 2025 execution timeline is no longer necessary.

• Estate planning becomes a longer-arc strategy rather than a deadline-driven activity.

What stays the same:

• High-net-worth families above $14M-$28M (depending on marital status) still face estate tax exposure at 40%.

• Future legislative changes remain possible — locking in current exemption through completed transfers retains value.

• State estate tax exposure continues in 12+ states with much lower thresholds.

• Dynastic wealth planning (multi-generational trusts) provides creditor protection, divorce protection, and family governance benefits beyond pure tax planning.

For families above the threshold, the conversation shifts from "execute by year-end 2025" to "build a structured multi-year estate plan" — but the underlying need for planning remains.

QBI Deduction Optimization Continues

With §199A made permanent, pass-through business owners no longer face the 2026 expiration. However, the SSTB exclusions, W-2 wage limits, UBIA limits, and threshold management opportunities all continue:

• Threshold management: For owners near the threshold ($241,950 single / $483,900 joint), retirement plan contributions, charitable giving, and other AGI-reducing strategies preserve QBI eligibility.

• Aggregation elections: For owners with multiple related businesses, aggregation can optimize W-2 wage and UBIA calculations.

• SSTB analysis: Determining whether a business is a Specified Service Trade or Business remains critical at higher income levels.

• S-corp salary calibration: Reasonable compensation analysis continues to drive the trade-off between W-2 wages and K-1 distributions.

Capturing New OBBB Deductions

Tip Income Deduction

For workers in tipping industries (food service, beauty, hospitality, hospitality):

• Track and document tip income carefully (separate from wage income).

• Coordinate with employer reporting on Form W-2.

• Verify income falls within the deduction's eligibility limits.

• For employer reporting compliance, ensure tips are properly reported through payroll.

Overtime Pay Deduction

For non-exempt hourly workers earning overtime:

• Verify overtime is properly classified (not regular wages misclassified).

• Review pay stubs to confirm overtime hours and pay.

• Coordinate with employer year-end W-2 reporting.

• Ensure income falls within the deduction's eligibility range.

Auto Loan Interest Deduction

For purchasers of qualifying U.S.-assembled vehicles:

• Verify vehicle qualifies (assembly location, type, MSRP limits).

• Track loan interest paid through annual lender statements.

• Coordinate with vehicle financing decisions — financing may now be more attractive than cash purchase for some buyers.

• Review post-purchase to claim the deduction on the tax return.

Senior Tax Deduction

For taxpayers age 65 or older:

• Layer with existing over-65 standard deduction increase.

• Coordinate with retirement income planning (RMDs, Social Security, pension).

• Subject to income phase-outs for high-earning seniors.

• Plan around the deduction's interaction with other senior-specific provisions.

Retroactive Section 174 R&D Recovery

For companies that capitalized domestic R&D under the 2022-2024 §174 rules:

1. Calculate the cumulative additional deduction available under restored full deductibility.

2. Determine whether amended returns or Form 3115 accounting method change is the better recovery path.

3. File the appropriate documentation.

4. Receive refunds of overpaid 2022-2024 federal taxes.

For software companies, technology firms, and R&D-intensive businesses, the recovery can amount to hundreds of thousands of dollars per year of operation under the prior rules.

Retroactive Bonus Depreciation Recovery

For property placed in service in 2023 (80% bonus) or 2024 (60% bonus):

1. Identify property where the additional 20% (2023) or 40% (2024) bonus depreciation can be claimed retroactively.

2. File amended returns or Form 3115 to claim the additional deduction.

3. Receive refunds of overpaid federal taxes.

For capital-intensive businesses, this can produce immediate cash refunds with significant business impact.

Capital Expenditure Strategy

With 100% bonus depreciation permanent and §179 expansion:

• Equipment purchases generate immediate full deductibility.

• Cost segregation studies become even more valuable (reclassified components qualify for 100% bonus).

• Real estate component analysis (HVAC, roofs, security under §179 for non-residential) remains valuable.

• Section 179 limit increase to $2.5M expands the per-business expensing capacity.

Business Entity Reconsideration

Pre-OBBB, some pass-through businesses were considering C-corp conversion if §199A sunsetted:

• With §199A permanent, the C-corp conversion calculus is significantly less favorable.

• S-corp election remains the typical optimal structure for closely-held businesses.

• Continued attention to reasonable compensation, retirement plans, and accountable plan reimbursements.

SALT Cap Continues

With the $10,000 SALT cap permanent under OBBB:

• PTET elections remain valuable in high-tax states for pass-through business owners.

• High-tax-state residents continue to face the limitation on personal SALT deduction.

• Domicile-shift planning to no-tax states retains value for retirees and business owners.

• State estate tax exposure remains in non-conforming states.

Multi-Year Income Smoothing

With marginal rates permanent, the year-to-year income smoothing strategy shifts:

• Bracket-line management remains valuable.

• "Bunching" deductions (charitable giving, medical expenses) continues.

• Retirement contribution timing optimizes around current (rather than future) brackets.

• Business income timing focuses on absolute level optimization rather than rate-trajectory positioning.

Investment and Capital Gains Planning

With long-term capital gains rates unchanged by OBBB:

• 0% long-term capital gains bracket (taxable income under $96,700 joint for 2025) continues.

• Tax-gain harvesting in low-income years remains valuable.

• Tax-loss harvesting continues as a year-round optimization opportunity.

• Asset location strategy (taxable vs tax-deferred vs Roth) continues to drive after-tax returns.

Common Mistakes Post-OBBB

• Continuing to execute "must complete by 2025" estate planning urgency that's no longer necessary.

• Failing to claim retroactive §174 R&D and bonus depreciation refunds.

• Missing the new tip, overtime, and auto loan interest deductions.

• Continuing C-corp conversion analyses based on the assumed §199A sunset.

• Failing to update planning models with the permanent rate structure.

• Not capturing the senior tax deduction for eligible retirees.

Bottom Line

The One Big Beautiful Bill Act fundamentally reshapes long-term tax planning. The pre-2026 sunset urgency is largely eliminated for most provisions, but the planning opportunities continue — they're just on a longer time horizon. The retroactive recovery opportunities for Section 174 R&D and bonus depreciation deserve immediate attention. The new deductions introduced by OBBB require integration into client return preparation. And the underlying tax planning toolkit — Roth conversions, QBI optimization, estate transfers, capital expenditure timing, asset location — continues to provide compound value over multi-year horizons. Working with a CPA who has internalized OBBB's implications is essential for capturing the full set of opportunities.
