What Were the Tax Cuts Expiring 2025?
Quick Answer: The 2017 Tax Cuts and Jobs Act (TCJA) included sunset provisions that were scheduled to expire on December 31, 2025. Without intervention, this would have eliminated 100% bonus depreciation and reduced the 20% QBI deduction, creating a significant tax cliff for business owners and investors.
When Congress passed the 2017 Tax Cuts and Jobs Act, they included numerous tax breaks designed to stimulate economic growth and business investment. However, many of these provisions had “sunset clauses”—automatic expiration dates built in. Unless extended or made permanent, these tax cuts expiring 2025 would have created a major “tax cliff” on January 1, 2026.
The most impactful expiring provision was 100% bonus depreciation. This allowed businesses to immediately deduct the full cost of equipment and machinery purchases in the year acquired. Without this benefit, bonus depreciation was scheduled to phase down to 80% in 2026, continuing to decline by 20% each year until reaching zero by 2027. This would have dramatically increased the effective cost of capital expenditures for manufacturers, construction companies, and other equipment-intensive businesses.
The Qualified Business Income Deduction at Risk
Another major expiring provision was the 20% Qualified Business Income (QBI) deduction. This powerful deduction allowed eligible business owners to deduct 20% of their qualified business income, effectively reducing their taxable income by one-fifth. Pass-through entities like S-Corps, LLCs, partnerships, and sole proprietorships benefited tremendously from this provision. Without the One Big Beautiful Act, this deduction would have expired completely for 2026, eliminating significant tax savings for millions of self-employed professionals and small business owners.
The threat of losing these provisions created immense uncertainty in business planning. Company executives couldn’t commit to long-term capital investments if they didn’t know whether 100% bonus depreciation would be available. Entrepreneurs couldn’t confidently project future tax liabilities. This uncertainty tax, while invisible, cost businesses millions in delayed investments and reduced expansion plans.
The Cascading Impact on Smaller Businesses
For small business owners structured as pass-through entities, the combined impact of these expiring provisions would have been catastrophic. A business owner with $100,000 in qualified business income would have lost access to the $20,000 QBI deduction. Simultaneously, any equipment purchases would have faced dramatically reduced depreciation benefits. The cumulative effect would have resulted in thousands of dollars in additional annual tax obligations for mid-sized businesses.
How Did the One Big Beautiful Act Prevent the Tax Cliff?
Quick Answer: The One Big Beautiful Act (OBBBA), signed July 4, 2025, made 100% bonus depreciation and the 20% QBI deduction permanent. It also expanded the SALT deduction, repealed R&D amortization requirements, and introduced new deductions for tips and overtime.
In a historic legislative achievement, Congress passed the One Big Beautiful Act to address the impending tax cliff. Unlike previous temporary extensions, this legislation made key provisions permanent, fundamentally shifting the tax landscape for 2026 and all subsequent years.
The OBBBA represented a bipartisan acknowledgment that business certainty drives investment and economic growth. By making these provisions permanent rather than extending them temporarily, Congress removed what economists call “policy risk”—the uncertainty that discourages long-term planning. A business owner can now confidently invest in equipment knowing that 100% bonus depreciation will be available indefinitely.
The Permanence Factor Changes Everything
Prior tax reforms, including the Reagan-era cuts of 1981 and even the 2017 TCJA, included sunset provisions. This created a “ticking clock” mentality where businesses knew they had limited time to exploit certain benefits. The OBBBA eliminated this ticking clock for bonus depreciation and the QBI deduction. Corporations and small businesses can now make 10, 20, and 30-year capital expenditure plans with confidence that these provisions will remain in place.
This permanence has already been reflected in market behavior. In the months following the OBBBA’s enactment, major corporations announced record capital expenditure plans. The industrial sector experienced particularly strong performance as companies rushed to modernize equipment and expand manufacturing capacity. A projected $129 billion reduction in corporate tax bills for S&P 500 companies in 2026 alone demonstrates the magnitude of tax cuts expiring 2025 prevention.

Which Provisions Are Now Permanent for 2026?
Quick Answer: For 2026, the permanent provisions include 100% bonus depreciation for all business property, the 20% QBI deduction for pass-through entities, immediate R&D expensing, and expanded SALT deduction limits through 2029.
The One Big Beautiful Act made several critical provisions permanent, fundamentally restructuring the federal tax code for long-term stability. Understanding these permanent changes is essential for effective 2026 tax planning.
100% Bonus Depreciation (Now Permanent)
For tax year 2026 and all future years, businesses can continue to deduct 100% of the cost of qualifying property in the year the asset is placed in service. This provision applies to tangible personal property, including machinery, equipment, vehicles, and computers. The permanence of this provision means businesses no longer need to depreciate assets over 5, 7, or 10-year MACRS schedules. They can immediately write off the full amount in year one.
Consider a manufacturing company that purchases $5 million in new production equipment for their Tennessee facility. Under 100% bonus depreciation, they can deduct the entire $5 million in 2026, reducing their taxable income by $5 million. This creates substantial cash flow benefits through reduced tax liability, allowing reinvestment in the business.
20% QBI Deduction (Now Permanent)
The Qualified Business Income deduction remains available for 2026 without any sunset date. Pass-through entity owners—including S-Corp shareholders, LLC members, partnership owners, and sole proprietors—can deduct 20% of their qualified business income. This deduction is taken above-the-line and can significantly reduce taxable income for eligible business owners.
For example, a real estate investor with $200,000 in qualified rental income can claim a $40,000 QBI deduction for 2026, reducing their effective tax burden substantially. This benefit applies to most business structures, making it one of the most valuable provisions ever included in federal tax law.
100% R&D Expensing (Repealed 5-Year Amortization)
The OBBBA eliminated the mandatory five-year amortization requirement for Research and Development (R&D) costs. Previously, companies were required to amortize domestic R&D expenses over five years. This provision changes allowed companies to immediately expense 100% of domestic R&D investments in the year incurred. This change particularly benefits pharmaceutical companies, technology firms, and any business engaging in significant research activities.
| Provision | 2026 Status | Impact on Businesses |
|---|---|---|
| 100% Bonus Depreciation | Permanent | Full-year deduction for equipment purchases |
| 20% QBI Deduction | Permanent | 20% reduction in taxable business income |
| 100% R&D Expensing | Permanent | Immediate deduction of all research costs |
| SALT Deduction Limit | $40,000 (MFJ) Through 2029 | Quadruple increase from prior $10,000 cap |
| Qualified Tips Deduction | New for 2026 | Deduction for service industry workers |
| Qualified Overtime Deduction | New for 2026 | Deduction for eligible overtime income |
How Do Tax Cuts Expiring 2025 Affect Self-Employed Contractors?
Quick Answer: Self-employed contractors benefit from permanent 20% QBI deductions, new qualified tips and overtime deductions, and the $24,500 2026 401(k) contribution limit, allowing greater tax-advantaged retirement savings.
Self-employed contractors and 1099 workers were among the most vulnerable to tax cuts expiring 2025. Without the QBI deduction, many independent professionals would have faced significantly higher effective tax rates. The permanence of these provisions provides crucial stability for freelancers, consultants, and gig-economy workers.
Additionally, 2026 introduces new tax breaks specifically for self-employed workers. The qualified tips deduction allows service industry workers to deduct certain tip income, though the IRS recently clarified that self-employed filers face stricter requirements than employees. Similarly, the qualified overtime deduction provides partial deductions for eligible overtime compensation, though again, self-employed individuals have more restrictive qualification standards.

401(k) and Retirement Planning for 2026
Self-employed individuals can take advantage of higher retirement contribution limits in 2026. The 401(k) contribution limit for 2026 is $24,500 per person, with an additional $7,500 catch-up contribution available for those aged 50 and over. This brings the maximum total contribution to $32,000 for older workers. These contributions reduce current taxable income while building retirement wealth, combining the benefits of tax cuts expiring 2025 prevention with long-term retirement security.
What Is the Impact on Real Estate Investors and Businesses?
Quick Answer: Real estate investors benefit from permanent bonus depreciation on building improvements, continued cost segregation opportunities, and the expanded $40,000 SALT deduction through 2029, creating substantial tax planning advantages.
Real estate investors experienced unique challenges from tax cuts expiring 2025. Depreciation is among the most powerful deductions available to rental property owners, allowing them to deduct the theoretical annual decline in property value even when rents increase. The threat of losing 100% bonus depreciation represented a material threat to real estate investment returns.
For 2026, the permanence of 100% bonus depreciation combined with cost segregation studies creates extraordinary tax planning opportunities. A real estate investor who purchases a commercial property for $2 million can potentially accelerate depreciation deductions through cost segregation, claiming larger depreciation amounts in early years of ownership. This creates significant tax deferral benefits, allowing 2026 tax law changes to enhance overall real estate profitability.
The SALT Deduction Expansion for High-Net-Worth Investors
One of the most significant benefits of the OBBBA for real estate investors is the quadrupling of the SALT (State and Local Taxes) deduction limit. Previously capped at $10,000 for married couples filing jointly, the limit has expanded to $40,000 through 2029. This change particularly benefits investors in high-tax states like California, New York, and New Jersey.
A real estate investor with a $2 million property in California and annual property taxes of $24,000 plus state income taxes of $20,000 can now deduct the full $44,000 in state and local taxes, reducing taxable income substantially. This SALT expansion alone can result in thousands of dollars in annual tax savings for affluent investors, particularly homeowners with significant real estate portfolios.
Business Owner Expansion Strategies
Small and mid-sized business owners can now commit to significant capital expenditure plans with confidence. Manufacturing facilities, construction companies, and equipment-intensive businesses are increasingly announcing major expansion projects, directly attributable to the permanence of 100% bonus depreciation. A business owner contemplating a $500,000 equipment purchase can now deduct the entire amount in 2026, creating substantial tax benefits that fund the investment.
Uncle Kam in Action: How One Real Estate Investor Saved $87,000 Through Tax Cuts Permanence
Meet Marcus, a high-net-worth real estate investor based in California managing a diverse portfolio including rental properties, commercial investments, and development projects. At the beginning of 2026, Marcus faced a critical decision: with tax cuts expiring 2025, he needed to understand how the new legislative environment would affect his tax planning.
Marcus’s portfolio included a $3 million commercial property recently improved with $600,000 in building enhancements eligible for accelerated depreciation. Under the previous uncertain environment, Marcus worried that bonus depreciation might phase down or expire. Working with Uncle Kam’s tax strategists, Marcus implemented a comprehensive cost segregation study on the property, separating building components into personal property (accelerated), land improvements (accelerated), and building structures (standard depreciation).
The tax strategists identified that with permanent 100% bonus depreciation now guaranteed through 2026 and beyond, Marcus could claim accelerated deductions of $320,000 in 2026 alone. Additionally, the expanded SALT deduction limit allowed Marcus to deduct property taxes and state income taxes totaling $48,000 instead of the previous $10,000 limitation.
Combined impact: Marcus achieved nearly $87,000 in additional deductions for 2026, reducing his effective tax rate from 37% to 28% on his investment income. The tax savings of $26,000 in 2026 alone more than paid for the cost segregation study, with ongoing benefits in subsequent years. Critically, Marcus gained the confidence to move forward with a $2 million expansion plan for his portfolio, knowing that 100% bonus depreciation would remain available to fund this growth through tax benefits.

2026 Tax Savings: $26,000
ROI in First Year: 217%
Multi-Year Benefit: $185,000+ (five-year projection)
Next Steps
Understanding tax cuts expiring 2025 and how the One Big Beautiful Act prevents a tax cliff is the first step. Now, implement these strategies to maximize your 2026 benefits. Start by documenting all business equipment and building improvements eligible for accelerated depreciation. For real estate investors, commission a cost segregation study to optimize your depreciation deductions. Self-employed contractors should maximize their $24,500 401(k) contributions and track all qualified business income for the QBI deduction. Consider working with business tax strategists who specialize in maximizing permanent tax benefits to ensure you’re leveraging every advantage of the new permanent provisions. Finally, if you haven’t reviewed your entity structure since the OBBBA was enacted, consult with a tax professional about whether an S-Corp election or other strategic changes could further enhance your tax efficiency for 2026 and beyond.
Frequently Asked Questions
Are the tax cuts expiring 2025 now permanent for all businesses?
Yes, for the most critical provisions. The 100% bonus depreciation and 20% QBI deduction are now permanent under the One Big Beautiful Act. However, some provisions like the expanded SALT deduction are permanent only through 2029, after which the limit reverts to $10,000 for married couples filing jointly. Always verify the current status of any deduction before implementing major tax planning strategies.
Can a self-employed contractor claim both the QBI deduction and the new tips deduction?
Yes, but with limitations. The QBI deduction applies to all qualified business income for self-employed workers. The tips deduction is separate. However, the IRS recently clarified that for self-employed individuals, tips income used to calculate the tips deduction must be reduced by the deductible portion of self-employment tax and other business deductions. This can reduce the benefit of the tips deduction for self-employed workers compared to employees.
How long will the expanded $40,000 SALT deduction limit remain in effect?
The expanded SALT deduction limit of $40,000 for married couples filing jointly is permanent through 2029 under the One Big Beautiful Act. After 2029, the limit is scheduled to revert to $10,000 unless Congress extends it again. Real estate investors and high-income earners in high-tax states should plan accordingly, potentially accelerating deductions before 2030.
What specific equipment qualifies for 100% bonus depreciation in 2026?
Tangible business property generally qualifies for 100% bonus depreciation, including machinery, equipment, vehicles placed in business service, and computer equipment. Land and certain land improvements do not qualify. Building structures qualify only if placed in service after September 28, 2017. Qualified leasehold improvements, qualified restaurant property, and qualified retail improvement property have specific rules. Consult with a tax professional to verify whether specific assets qualify.
Can I retroactively claim the QBI deduction for 2025 if I missed it?
If you didn’t claim the QBI deduction on your 2025 return, you may be able to file an amended return using professional tax preparation and filing services to claim the deduction. Form 1040-X allows you to amend your 2025 return within three years of the original filing date. Many taxpayers missed this deduction on their initial filing, so amended returns claiming the QBI deduction are common.
How does the permanent R&D expensing change affect my 2026 tax planning?
For 2026, businesses conducting research and development can immediately deduct 100% of eligible R&D costs in the year incurred, rather than amortizing them over five years. This creates substantial first-year deductions for research-intensive companies. If your business spent $500,000 on qualified research in 2026, you can now deduct the full amount immediately, creating a $500,000 reduction in taxable income. This particularly benefits pharmaceutical, technology, and manufacturing sectors.
What documentation do I need for bonus depreciation claims on my 2026 tax return?
For bonus depreciation claims, you must maintain documentation showing the asset’s acquisition date, cost, business use percentage, and eligibility. Keep invoices, purchase agreements, and proof of payment. For building improvements, retain contracts and specifications showing the work performed. The IRS may request this documentation during an examination, so maintaining detailed records is essential. Many businesses use asset management software to track this information systematically.
If I didn’t take advantage of permanent deductions in 2026, can I claim them in 2027?
Yes, since these provisions are now permanent, they remain available in 2027 and future years. However, there is no benefit to delaying deductions. Claiming deductions in 2026 provides immediate tax savings that can be reinvested in your business. Additionally, depreciation deductions cannot be carried forward indefinitely—they’re tied to specific assets. Claiming bonus depreciation when assets are placed in service is the appropriate timing.
