Navigating the OBBBA & WA State Tax Changes: How Individuals & Businesses Can Plan for the Road Ahead

Tax laws are shifting once again, and this time, both federal and state updates are on the table. With the passage of the One Big Beautiful Bill Act (OBBBA) in Congress and new state-level changes in Washington, individuals and businesses alike are assessing what these updates mean for their financial future.

While these reforms introduce added complexity, they also create strategic planning opportunities. The key is understanding how the changes apply to your situation and identifying steps to reduce risk and maximize available benefits.

Federal Highlights: Key Implications of the OBBBA

The OBBBA represents one of the most comprehensive updates to the federal tax code in recent years. While the legislation spans dozens of provisions, the most impactful changes for individuals and businesses fall into a few core areas.

For Individuals

1. Permanent Extension of TCJA Tax Rates and Brackets

The OBBBA makes permanent the lower individual income tax rates and wider tax brackets introduced under the TCJA. The top individual income tax rate remains 37%, avoiding a return to 39.6%.

2. Increased Standard Deduction

The higher standard deduction is now permanent and will continue to be indexed for inflation.

  • Single filers & married filing separately: $15,000
  • Married filing jointly (including surviving spouses): $30,000
  • Head of household: $22,500

3. Senior Deduction

Taxpayers aged 65+ can claim a $6,000 deduction (2025–2028) with a phase-out starting at $75,000 MAGI ($150,000 for joint filers), reduced by 6% for each $1,000 above the threshold.

4. State and Local Tax (SALT) Deduction Cap

For 2025-2029, the SALT deduction limit rises from $10,000 to $40,000, phasing out starting at $500,000 MAGI. The cap and threshold increase 1% annually, with a minimum deduction of $10,000.

5. Expanded Family Tax Credits

Child Tax Credit increases from $2,000 to $2,200 per qualifying child (2025), indexed for inflation.

6. No Tax on Overtime and Tips

Above-the-line deductions for tip income (up to $25,000) and qualified overtime pay (up to $12,500 individual/$25,000 joint) apply for 2025–2028. Phase-outs start at $150,000 MAGI ($300,000 joint).

7. Interest Deduction on Principal Residence

Permanent $750,000 loan limit for acquisition debt; home equity interest continues to be excluded; mortgage insurance premiums treated as qualified residence interest starting 2026.

8. Interest Deduction on Domestic Auto Purchases

For 2025–2028, above-the-line deduction for interest on loans for U.S.-made passenger vehicles, up to $10,000 annually. Phase-out begins at $100,000 MAGI ($200,000 joint).

9. Section 1202 Small Business Stock

Tiered gain exclusion: 50% (≥3 years), 75% (≥4 years), 100% (≥5 years) for stock issued after July 4, 2025. Per-issuer cumulative exclusion rises to $15 million; aggregate gross asset limit to $75 million; both indexed.

10. Above-the-Line Charitable Contribution Deduction

Starting in 2026, non-itemizing taxpayers can deduct up to $1,000 ($2,000 joint) for charitable contributions.

11. Estate and Gift Tax Exemption

The lifetime exemption increases to $15 million per person, indexed for inflation starting in 2026.

For Businesses

1. 100% Bonus Depreciation Restored

The OBBBA reinstates 100% bonus depreciation for qualified property placed in service from January 19, 2025.  

2. Qualified Business Income (QBI) Deduction Made Permanent

20% deduction for many pass-through entities, providing long-term planning certainty.

3. Research & Development Expensing

Domestic R&D expenses can now be immediately expensed (2025 onward). Qualifying small businesses (<$31M gross receipts) can amend prior returns. Software development included.

4. Pass-Through Entity SALT Deduction Workaround

Maintains federal deduction for state taxes paid by pass-through entities on behalf of partners/shareholders.

5. Business Interest Limitation

IRC §163(j) modified: interest limitation now excludes depreciation, amortization, and depletion, reverting closer to original TCJA calculation.

6. Excess Business Loss Limitation

Permanent limits: $313,000 (single) / $626,000 (joint) for 2025; excess losses carried forward as NOLs with 80% taxable income cap.

7. Qualified Opportunity Zone (QOZ) Program

Tax incentives for investing deferred capital gains: deferred gains recognized by Dec 31, 2026, if invested before Jan 1, 2027. Post-2026 investments enjoy deferral, 10% basis increase after 5 years, 30% for rural funds, and no tax after 10 years.

In light of these changes, individuals should revisit estate and family tax planning strategies, while businesses may want to model capital spending, payroll, and R&D investments.

Washington State Tax Changes: What to Expect in 2025

In addition to federal reforms, Washington has enacted state-level tax changes that will affect both businesses and individuals.

1. Capital Gains Tax Rate Increase

Beginning January 1, 2025, long-term capital gains are taxed at 7% up to $1 million and 9.9% on amounts above $1 million. This reflects the prior 7% base rate plus a new 2.9% surcharge on high-value gains.

2. Estate Tax Threshold Raised

For decedents dying on or after July 1, 2025, the state estate tax exclusion increases from $2.193 million to $3 million. The exemption will now be indexed annually for inflation, a change from prior law.

4. B&O Increase for Retailing, Wholesaling, and Manufacturing
