What Is the OBBBA and Why Does It Matter for Chicago Businesses?
Quick Answer: The One Big Beautiful Bill Act (OBBBA), signed July 4, 2025, makes the Tax Cuts and Jobs Act permanent and introduces sweeping new deductions. For Chicago 2026 tax planning, this means a permanent 20% QBI deduction, accelerated depreciation, and strategic opportunities to reduce your taxable business income significantly.
The OBBBA represents the most significant tax restructuring for business owners since 2017. Unlike previous temporary tax provisions, the OBBBA makes key benefits permanent, creating long-term planning opportunities for Chicago entrepreneurs, LLC owners, and S Corporation operators. For the 2026 tax year, this stability allows you to build tax strategy with confidence.
The legislation addresses multiple revenue sources simultaneously. The standard deduction expanded to $31,500 for married couples filing jointly and $15,750 for single filers. The state and local tax (SALT) cap increased to $40,000 through 2030. These changes directly impact Chicago business owners filing personal returns tied to their business income.
Beyond individual deductions, the OBBBA fundamentally reshapes how Chicago businesses approach capital investment and entity structure. The permanent 20% Qualified Business Income deduction eliminates the need to plan around sunset dates. Bonus depreciation at 100% and Section 179 expensing up to $2.5 million for small businesses create immediate deductions for equipment and property purchases.
Key Provisions Affecting Chicago Business Owners
- Permanent 20% QBI deduction with no sunset date (differs from prior temporary provisions)
- 100% bonus depreciation on qualified property purchases for immediate expense recognition
- Section 179 deduction limit increased to $2.5 million for small business equipment
- Operating loss limitation capped at 80% of taxable income (requires multi-year planning)
- Qualified Opportunity Zone programs extended with rolling investment windows
Pro Tip: File your 2026 Chicago tax return electronically and opt for direct deposit refunds to avoid processing delays. The IRS is phasing out paper checks, but e-filed returns with direct deposit process in under 21 days typically.
How Does the 20% QBI Deduction Work Under the OBBBA?
Quick Answer: The 20% Qualified Business Income deduction allows you to deduct one-fifth of your business income directly from your taxable income. For a Chicago business earning $100,000 in qualified income, this deduction reduces your taxable income by $20,000, potentially saving $4,000-$6,500 in federal taxes depending on your tax bracket.
The QBI deduction is one of the most powerful tax benefits for Chicago 2026 tax planning. Under the OBBBA, this deduction is now permanent, eliminating the uncertainty that plagued business owners in prior years. The deduction applies to pass-through entities including sole proprietorships, partnerships, S Corporations, and LLCs.
To calculate your QBI deduction, start with your business’s qualified business income. This includes net profit from your business operations after expenses but before capital gains and losses. Multiply this amount by 20% to determine your deduction. You claim this on Form 1040, Line 9c.
QBI Deduction Calculation Example
Consider Jennifer, a Chicago-based marketing consultant operating as an S Corporation for 2026. Her qualified business income for 2026 is $150,000. Her QBI deduction calculation:
- Qualified Business Income: $150,000
- QBI Deduction (20%): $150,000 × 0.20 = $30,000
- Taxable Income Reduction: $30,000 saves approximately $6,900 in federal taxes (24% bracket)
Limitations and Phase-Out Rules for High Earners
The OBBBA introduced new limitations on deductions for high-income taxpayers beginning in 2026. High earners in Chicago face restrictions on itemized deductions that were not present under prior law. These restrictions affect the value of charitable contributions and other deductions.
For the QBI deduction specifically, ensure you have good documentation of your business income, deductible expenses, and entity structure. Work with a tax strategy professional to model your specific situation and determine the optimal approach for your Chicago business.
What Are the Accelerated Depreciation Opportunities for 2026?
Quick Answer: Under the OBBBA, you can now deduct 100% of certain property acquisition costs immediately through bonus depreciation. For a Chicago business purchasing $50,000 in equipment, you could claim a $50,000 deduction in 2026 instead of depreciating it over five to seven years, unlocking immediate cash flow benefits.
Accelerated depreciation represents one of the most valuable tax advantages in the OBBBA for Chicago business owners planning capital investments. The 100% bonus depreciation allowance applies to qualified property placed in service in 2026, including machinery, equipment, vehicles, and certain other tangible business property.
This strategy works synergistically with Section 179 expensing, which allows immediate deduction of up to $2.5 million in asset costs. Together, these provisions can create significant tax deductions in the year you make capital purchases, reducing your 2026 taxable income substantially.
Bonus Depreciation vs. Section 179 Comparison
| Strategy | Bonus Depreciation | Section 179 Expensing |
|---|---|---|
| 2026 Deduction Rate | 100% of qualified property cost | Up to $2.5 million immediately |
| Eligible Property Types | Machinery, equipment, tangible business property | Equipment, vehicles, property improvements |
| Income Limitation | None (full deduction available) | Limited to taxable income from business |
| Planning Consideration | Can combine with Section 179 for maximum benefit | Requires election on Form 4562 |
Multi-Year Planning for Capital Purchases
The interaction between bonus depreciation, Section 179, and operating loss limitations requires careful planning. If you claim a large deduction in 2026 and generate an operating loss, remember that losses can now only offset 80% of taxable income. This means some losses carry forward to 2027.
Consider spreading capital purchases between 2026 and 2027 to optimize the benefit. For example, if purchasing $100,000 in equipment, you might take 50% of the deduction in 2026 and 50% in 2027 to avoid excess loss carryforwards and improve overall tax results across both years.
Should You Elect S Corp Status for Optimal Tax Savings?
Quick Answer: S Corporation election can reduce self-employment taxes by $10,000 to $50,000+ annually by separating business income into salary (subject to payroll taxes) and distributions (not subject to self-employment tax). A Chicago business with $150,000 annual income could save $7,000-$10,000 through S Corp election combined with the 20% QBI deduction.
The S Corporation election creates significant tax savings for Chicago service businesses, consultancies, and professional practices. By paying yourself a reasonable W-2 salary and taking the remainder as distributions, you reduce the amount of income subject to 15.3% self-employment taxes.
The IRS requires S Corporation owners to pay “reasonable compensation” as W-2 wages. This typically means paying yourself a salary that reflects the work you personally perform in the business. The remaining profit can be taken as distributions, which avoid self-employment taxes entirely.
When combined with the 20% QBI deduction, S Corporation election becomes even more powerful. The distribution portion of your income qualifies for the QBI deduction, further reducing your taxable income. Use our LLC vs S-Corp Tax Calculator for Wheeling to model the specific savings for your business structure and estimate annual benefits.
When S Corp Election Makes Financial Sense
- Annual business net income exceeds $60,000 (savings typically exceed accounting costs)
- You can justify a reasonable W-2 salary based on your personal service in the business
- Your business is currently structured as an LLC or sole proprietorship
- You want to access the QBI deduction on business distributions
- You can maintain payroll records and file quarterly employment tax forms
Did You Know? The IRS has increased enforcement against S Corporation owners who pay unreasonably low W-2 salaries. If you claim distributions significantly higher than your salary, expect potential audit risk. Consult a tax strategist specializing in entity structuring to establish reasonable compensation documentation.
How Can Strategic Entity Structuring Improve Your Tax Position?
Quick Answer: Strategic multi-entity structures can separate high-tax-rate income from passive income, create independent deduction opportunities, and improve asset protection. A Chicago business using a holding company and operating company structure can access multiple QBI deductions and optimize depreciation timing across entities.
Beyond the basic LLC vs. S Corporation decision, sophisticated Chicago business owners should consider multi-entity tax structuring. This approach separates different income streams and creates tax planning opportunities that individual entity owners cannot access.
A common structure involves an S Corporation operating company and an LLC holding company. The operating company handles active business income and claims W-2 wage deductions. The holding company owns real estate or equipment and receives lease payments from the operating company, creating independent deductions while centralizing asset ownership.
Real Estate Income Separation Strategy
For Chicago business owners with real estate holdings, separating real estate from operations provides significant tax benefits. A property holding LLC can own business property and lease it to your operating company at fair market rates.
This structure accomplishes multiple objectives. The property LLC claims depreciation deductions on the real estate, reducing taxable income from that entity. The operating company deducts the lease payments as business expenses. This approach maximizes overall deductions while maintaining separate liability protection for real estate assets.
How Can You Reinvest Tax Savings for Maximum Growth?
Quick Answer: Tax savings from accelerated depreciation and QBI deductions free up cash flow that can be reinvested in business growth, strategic expansion, technology upgrades, or Roth conversions. A Chicago business saving $15,000 in taxes through depreciation deductions should allocate those funds strategically.
The OBBBA tax benefits create immediate cash flow improvements that require strategic planning. Rather than letting tax savings evaporate through discretionary spending, develop a reinvestment strategy that balances growth, protection, and retirement preparation.
Consider allocating a portion of tax savings to technology upgrades that improve operational efficiency. Another portion could fund key employee bonuses or retirement plan contributions. Use remaining funds to build business contingency reserves or accelerate debt paydown to improve balance sheet strength.
Recommended Reinvestment Allocation
| Reinvestment Category | Allocation % | Example (for $15,000 savings) |
|---|---|---|
| Business Growth (equipment, marketing) | 40% | $6,000 |
| Retirement/Tax-Deferred Savings | 30% | $4,500 |
| Emergency/Contingency Reserve | 20% | $3,000 |
| Debt Reduction | 10% | $1,500 |
Uncle Kam in Action: How Marcus Saved $18,500 on Chicago 2026 Taxes
Marcus owns a Chicago-based management consulting firm operating as an LLC with $220,000 annual net income. Before 2026 planning, he was paying substantial self-employment taxes and missing deduction opportunities available under the OBBBA.
The Challenge: Marcus needed to reduce his tax burden while maintaining business reinvestment capability. His firm had just purchased $40,000 in software and office equipment requiring tax-efficient treatment. His prior tax strategy hadn’t taken advantage of permanent OBBBA provisions.
Uncle Kam’s Strategy: We implemented a three-part Chicago 2026 tax planning approach: First, we elected S Corporation status, establishing a $140,000 reasonable W-2 salary with $80,000 in distributions. This separated self-employment taxes from distribution income. Second, we claimed 100% bonus depreciation on the $40,000 equipment purchase. Third, we calculated the QBI deduction on the distribution income, further reducing taxable income.
The Results: Marcus’s 2026 tax savings broke down as follows:
- S Corp self-employment tax reduction: $9,200 (on $80,000 distributions)
- QBI deduction tax savings: $5,800 (20% of $80K distribution at 32.5% marginal rate)
- Bonus depreciation deduction savings: $3,500 (100% of $40K at 35% marginal rate)
- Total First-Year Tax Savings: $18,500
The tax savings from the OBBBA provisions freed up cash flow that Marcus strategically reinvested. He allocated $7,400 toward additional equipment purchases in Q4 2026 to maximize depreciation benefits. He contributed $8,500 to his solo 401(k) retirement plan. He reserved $2,600 for contingency reserves.
This is exactly the type of strategic tax advisory approach that turns OBBBA benefits into lasting business wealth. By taking action before year-end, Marcus positioned his business to continue realizing these advantages through multi-year planning.

Frequently Asked Questions
When Does the 20% QBI Deduction Apply to My Business?
The QBI deduction applies to qualified business income from pass-through entities in 2026 and beyond under the OBBBA. This includes sole proprietorships, partnerships, S Corporations, and LLCs. You claim the deduction on your personal Form 1040. The deduction is now permanent, unlike prior temporary provisions that expired periodically.
Can I Claim Bonus Depreciation and Section 179 on the Same Equipment?
Yes, you can combine these provisions strategically. However, you cannot claim both on identical assets. If you purchase $100,000 in equipment, you might claim 100% bonus depreciation on $60,000 and Section 179 on the remaining $40,000 (up to the $2.5 million limit). Plan this carefully to maximize your total deduction while respecting income limitations.
What Is Reasonable Compensation for S Corporation Owners?
The IRS defines reasonable compensation as the amount you would normally pay to an employee performing similar work. Document your salary decision with references to industry data, your personal service hours, and comparable positions. For a Chicago marketing consultant, reasonable salary might range $80,000-$150,000 depending on experience and client base. The IRS increasingly audits S Corp owner compensation, so conservative documentation is critical.
How Do Operating Loss Limitations Affect My 2026 Planning?
Under the OBBBA, net operating losses can offset only 80% of taxable income. If you generate a large loss in 2026, you cannot use 100% of it to offset that year’s income. The excess carries forward to 2027. This means you should model multi-year income projections. Spreading deductions across 2025 and 2026 (or 2026 and 2027) may produce better overall results than claiming all deductions in one year.
Should I Convert My Existing LLC to an S Corporation for 2026?
S Corporation election makes sense if your net business income exceeds $60,000 annually and you can document reasonable W-2 compensation. LLCs can elect S Corporation tax treatment without changing their legal structure. File Form 8832 before March 15, 2026 to make the election for 2026. However, S Corporation election requires payroll compliance and quarterly tax filings, so factor these costs into your decision.
What Happens to My Tax Plan if the OBBBA Provisions Change?
The OBBBA made these provisions permanent, eliminating sunset dates that affected prior tax laws. However, Congress can modify these provisions at any time through new legislation. Your best protection is working with a tax advisor who monitors legislative changes and adjusts your strategy accordingly. Review your tax plan annually as new guidance emerges.
