- Reduced individual tax brackets lowered the tax burden for pass-through entities like LLCs, S Corps, and sole proprietorships
- Enhanced bonus depreciation and Section 179 expensing allowed immediate deduction of business equipment purchases up to $1.16 million in 2025
- Over 90% of small businesses qualified for some form of tax benefit from Trump’s big beautiful bill according to IRS data
- Main Street businesses reported using tax savings for hiring, equipment upgrades, and local reinvestment, stimulating economic growth
What Is the Qualified Business Income Deduction?
Quick Answer: The QBI deduction allows eligible business owners to deduct up to 20% of their qualified business income, potentially saving thousands in taxes annually.
The Qualified Business Income deduction, introduced through Trump’s big beautiful bill, represents one of the most significant tax benefits for small business owners in recent history. This provision, codified as Section 199A of the Internal Revenue Code, allows eligible taxpayers to deduct up to 20% of their qualified business income from pass-through entities.
How the QBI Deduction Works
The deduction applies to income from:
- Sole Proprietorships: Schedule C business income
- S Corporations: Pass-through income reported on K-1
- Partnerships: Distributive share of partnership income
- LLCs: Income from single-member or multi-member LLCs taxed as partnerships
- Real Estate Investment Trusts (REITs): Publicly traded REIT dividends
| Business Income Level | Maximum QBI Deduction | Tax Savings (24% Bracket) |
|---|---|---|
| $50,000 | $10,000 | $2,400 |
| $100,000 | $20,000 | $4,800 |
| $200,000 | $40,000 | $9,600 |
Pro Tip: The QBI deduction is taken “below the line,” meaning it reduces your taxable income without affecting your adjusted gross income (AGI). This can help you qualify for other income-based deductions and credits.
Calculation Example
Consider a married couple filing jointly with $150,000 in qualified business income from their consulting firm:
- Qualified Business Income: $150,000
- QBI Deduction (20%): $30,000
- Tax Savings at 24% bracket: $7,200 annually
- Effective tax rate reduction: 4.8 percentage points
How Did Lower Tax Brackets Benefit Small Businesses?
Quick Answer: Trump’s tax reform reduced individual tax rates across most brackets, directly benefiting pass-through entities whose income flows through to owners’ personal tax returns.
Since most small businesses operate as pass-through entities (LLCs, S Corps, partnerships, and sole proprietorships), the reduction in individual tax rates created immediate tax relief. The 2025 tax brackets continue to reflect these lower rates, though they’re set to expire after 2025 unless extended by Congress.
Tax Bracket Comparison: Before vs After
| Income Range (Married Filing Jointly) | Pre-TCJA Rate | Post-TCJA Rate (2025) | Savings |
|---|---|---|---|
| $19,751 – $80,250 | 15% | 12% | 3% |
| $80,251 – $171,050 | 25% | 22% | 3% |
| $171,051 – $326,600 | 28% | 24% | 4% |
| $326,601 – $414,700 | 33% | 32% | 1% |
Real-World Impact on Cash Flow
For a small business owner with $200,000 in taxable income (married filing jointly), the tax savings from reduced brackets alone amount to:
- 12% bracket savings: $1,815 (on $60,499 of income)
- 22% bracket savings: $2,724 (on $90,800 of income)
- 24% bracket savings: $1,158 (on $28,950 of income)
- Total Annual Savings: $5,697 from bracket reductions alone
Did You Know? According to the Small Business Administration, businesses with fewer than 500 employees account for 99.9% of all U.S. businesses, meaning Trump’s big beautiful bill impacted virtually every small business owner in America.
What Enhanced Expensing Opportunities Were Created?
Quick Answer: The Tax Cuts and Jobs Act expanded bonus depreciation to 100% and increased Section 179 expensing limits, allowing businesses to immediately deduct equipment purchases rather than depreciating them over several years.
One of the most overlooked benefits of Trump’s big beautiful bill was the dramatic expansion of business expensing opportunities. These changes provided immediate cash flow benefits by allowing businesses to deduct the full cost of qualifying assets in the year of purchase.
Section 179 Expensing Enhancement
The Section 179 deduction allows businesses to expense (rather than depreciate) qualifying property in the year it’s placed in service. The TCJA significantly increased these limits:
- 2025 Limit: $1,160,000 (up from $500,000 pre-TCJA)
- Phase-out Threshold: $2,890,000 in qualifying purchases
- Qualifying Property: Machinery, equipment, furniture, software, and certain real property improvements
100% Bonus Depreciation
The TCJA introduced 100% bonus depreciation for qualifying assets, which has been gradually reduced but remains substantial:
| Tax Year | Bonus Depreciation Percentage | $100,000 Equipment Tax Benefit |
|---|---|---|
| 2025 | 60% | $60,000 first-year deduction |
| 2024 | 80% | $80,000 first-year deduction |
| 2018-2022 | 100% | $100,000 first-year deduction |
Qualified Improvement Property
The TCJA also expanded expensing to include certain real property improvements:
- Qualified Improvement Property: Interior improvements to nonresidential buildings
- Restaurant Property: Improvements to restaurant buildings
- Retail Property: Improvements to retail space
Pro Tip: Businesses can combine Section 179 expensing with bonus depreciation for maximum first-year deductions. Use Section 179 first, then apply bonus depreciation to remaining qualifying property.

What Are the Limitations and Phase-Outs?
Quick Answer: The QBI deduction has income-based limitations and excludes certain service businesses above threshold amounts, while most provisions of Trump’s big beautiful bill expire after 2025.

Uncle Kam in Action: Construction Company Owner Maximizes Trump Tax Savings
Client Snapshot: A construction company owner operating as an S Corporation specializing in commercial building projects.
Financial Profile: Annual business income of $280,000, with significant equipment purchases planned for expansion.
The Challenge: The client was unaware of how to maximize the benefits from Trump’s big beautiful bill and was missing substantial tax savings opportunities. He was paying unnecessary taxes and not taking advantage of enhanced expensing provisions for his heavy equipment purchases. Additionally, his S Corp salary structure wasn’t optimized for QBI benefits.
The Uncle Kam Solution: Our team conducted a comprehensive analysis of his business structure and implemented a multi-faceted tax strategy. We optimized his S Corp reasonable salary to $95,000, allowing $185,000 to flow through as QBI-eligible income. We then structured his $150,000 equipment purchase using Section 179 expensing to maximize first-year deductions. Finally, we implemented strategic timing for additional equipment purchases to utilize bonus depreciation benefits.
The Results:
- QBI Deduction Savings: $37,000 deduction resulting in $8,880 tax savings at 24% bracket
- Section 179 Expensing: $150,000 immediate deduction saving $36,000 in current-year taxes
- Self-Employment Tax Optimization: Additional $2,800 savings through salary restructuring
- Total Tax Savings: $47,680 in the first year
- Investment: The client invested $6,500 for comprehensive tax planning and implementation
- Return on Investment (ROI): An impressive 7.3x return on investment in the first year, freeing up substantial capital for business expansion and additional equipment purchases
The client used the tax savings to purchase additional equipment and hire two new employees, directly contributing to local economic growth – exactly the type of Main Street reinvestment that Trump’s big beautiful bill was designed to encourage.

Frequently Asked Questions
Does the QBI deduction apply to all business types?
The QBI deduction applies to pass-through entities including sole proprietorships, partnerships, S corporations, and single-member LLCs. C corporations don’t qualify because they’re subject to corporate-level taxation. However, rental real estate activities and REIT dividends can qualify for the deduction even if they’re not considered active businesses.
What happens to these tax benefits after 2025?
Most provisions from Trump’s big beautiful bill expire after December 31, 2025, including the QBI deduction and lower individual tax brackets. Unless Congress extends these provisions, tax rates will revert to pre-2018 levels, and the QBI deduction will disappear entirely. Business owners should plan accordingly and consider strategies to maximize benefits while they’re available.
Can I combine the QBI deduction with other business deductions?
Yes, the QBI deduction is taken “below the line” and doesn’t affect other business deductions. You can still claim all ordinary business expenses, Section 179 expensing, bonus depreciation, and other deductions. The QBI deduction is calculated after determining your net qualified business income, so maximizing business deductions actually helps preserve more income for the QBI calculation.
How do I know if my service business qualifies for QBI benefits?
Service businesses face restrictions based on income levels and business type. If your taxable income is below the threshold ($191,950 for single filers or $383,900 for married filing jointly in 2025), you generally qualify regardless of business type. Above these amounts, specified service trades or businesses (SSTBs) like law, accounting, consulting, and financial services face phase-outs and eventual elimination of the deduction.
What’s the difference between Section 179 expensing and bonus depreciation?
Section 179 expensing has a dollar limit ($1,160,000 in 2025) but can be used for both new and used property. Bonus depreciation has no dollar limit but applies at different percentages (60% in 2025) and traditionally required new property, though recent changes allow some used property. You can combine both methods: first apply Section 179 up to the limit, then use bonus depreciation on remaining qualifying assets.
How much can I realistically save with these tax strategies?
Savings vary significantly based on income level, business type, and entity structure. A typical small business owner with $150,000 in qualified business income might save $3,600 annually from the QBI deduction alone, plus additional savings from lower tax brackets. When combined with strategic expensing of equipment purchases, total tax savings can easily reach $10,000-$30,000 or more annually, depending on the business situation and planning strategies implemented.
