2026 Tax Law Changes Small Business Prep Checklist

The Tax Cuts and Jobs Act (TCJA) provisions that have shaped small business tax strategies since 2018 are set to expire at the end of 2025, creating significant changes for the 2026 tax year. Small business owners, CPAs, and tax professionals must begin preparing now for these substantial shifts in tax law that will impact everything from pass-through entity deductions to equipment depreciation schedules.

Understanding and preparing for these 2026 tax law changes small business owners will face is crucial for maintaining profitability and ensuring compliance. The expiration of key TCJA provisions will affect millions of small businesses across the United States, making strategic tax planning more important than ever.

Major Tax Law Expirations in 2026: What Small Businesses Need to Know

The expiration of TCJA provisions represents one of the most significant tax law changes small businesses will face in recent history. These changes will fundamentally alter how businesses calculate their tax liability and plan their financial strategies moving forward.

The most impactful changes include the elimination of the Section 199A qualified business income deduction, modifications to bonus depreciation schedules, and adjustments to various business deductions that have provided substantial tax savings since 2018. Small business owners must understand that these changes will generally result in higher effective tax rates unless Congress intervenes with new legislation.

Corporate tax rates, which were permanently reduced to 21% under the TCJA, will remain unchanged. However, pass-through entities including sole proprietorships, partnerships, S corporations, and LLCs will face the most significant impact from these expiring provisions.

The timing of these changes creates a unique planning opportunity for businesses in 2025. Strategic decisions made before December 31, 2025, can help minimize the impact of higher tax rates in 2026 and beyond. This includes accelerating income, timing equipment purchases, and restructuring business operations where beneficial.

Timeline of Key Expiration Dates

Understanding the specific timeline of these changes helps businesses plan accordingly:

Section 199A Pass-Through Deduction Changes for 2026

The Section 199A deduction has provided eligible pass-through entities with up to a 20% deduction on qualified business income since 2018. This deduction has been particularly valuable for small business owners, as it effectively reduces the top marginal tax rate on business income from 37% to 29.6% for qualifying taxpayers.

When this provision expires at the end of 2025, pass-through entities will lose this significant tax benefit entirely. For a small business owner with $100,000 in qualified business income, this could mean an additional $7,400 in federal income taxes annually, assuming they previously qualified for the full 20% deduction.

The elimination of the Section 199A deduction will disproportionately impact service-based businesses and higher-income business owners who currently benefit from this provision. Professional service firms, including accounting practices, law firms, and consulting businesses, should begin modeling the financial impact of this change on their cash flow and pricing strategies.

Planning Strategies for Section 199A Expiration

Small businesses can implement several strategies to prepare for the loss of this valuable deduction:

• Accelerate income into 2025 to maximize the final year of Section 199A benefits
• Consider business structure changes that might provide alternative tax advantages
• Evaluate equipment purchases and other deductible expenses to optimize tax positions
• Review pricing strategies to account for higher effective tax rates
• Explore retirement plan contributions and other tax-advantaged savings options

Business owners should work closely with their tax professionals to model different scenarios and determine the most advantageous approach for their specific situation. The complexity of these calculations often requires sophisticated tax software and professional expertise to navigate effectively.

Bonus Depreciation and Equipment Purchase Planning

Bonus depreciation has allowed businesses to immediately deduct a significant percentage of qualifying property costs in the year of purchase. This provision has been particularly valuable for small businesses investing in equipment, technology, and other capital assets necessary for operations.

The bonus depreciation percentage has been declining since 2023 and will reach zero percent for property placed in service after December 31, 2026. This means businesses will need to return to traditional depreciation schedules, spreading the cost of assets over multiple years rather than taking immediate deductions.

For small businesses planning significant equipment purchases, 2025 and 2026 represent critical decision points. Equipment placed in service during 2025 will qualify for 60% bonus depreciation, while equipment placed in service during 2026 will qualify for 40% bonus depreciation. After 2026, businesses will rely entirely on regular depreciation schedules.

Strategic Equipment Purchase Timing

The phase-out of bonus depreciation creates specific planning opportunities:

1. Evaluate current and planned equipment needs through 2027
2. Prioritize purchases that qualify for remaining bonus depreciation percentages
3. Consider the cash flow impact of returning to traditional depreciation schedules
4. Review financing options that might be more attractive with reduced tax benefits
5. Assess whether leasing arrangements might become more favorable than purchasing

Manufacturing businesses, construction companies, and technology-dependent service providers should pay particular attention to these changes. The ability to immediately deduct large equipment purchases has been a significant cash flow advantage that will be substantially reduced after 2026.

R&D Expense Capitalization Impact on Small Businesses

Unlike many TCJA provisions that are expiring, the requirement to capitalize and amortize research and development expenses over five years became effective in 2022 and remains in place. This change has already begun impacting small businesses engaged in product development, software creation, and other research activities.

Small businesses that previously deducted R&D expenses immediately now must spread these deductions over five years for domestic research or fifteen years for foreign research. This change significantly impacts cash flow for innovation-driven businesses, particularly startups and technology companies that rely heavily on R&D activities.

The ongoing nature of this requirement means businesses must continue adapting their financial planning and tax strategies to account for the delayed tax benefits of R&D investments. This is particularly challenging for small businesses with limited cash reserves who previously relied on immediate R&D deductions to reduce their tax liability.

Managing R&D Capitalization Requirements

Small businesses can implement several approaches to manage the ongoing impact of R&D capitalization:

• Carefully document and track all qualifying R&D expenses for proper capitalization
• Implement robust project tracking systems to allocate costs appropriately
• Consider timing of R&D projects to optimize amortization schedules
• Evaluate alternative business structures that might provide R&D tax advantages
• Explore federal and state R&D tax credits that remain available

Technology companies and businesses engaged in product development should work with tax professionals familiar with R&D capitalization rules to ensure compliance and optimize their tax positions within the current framework.

Essential Tax Planning Strategies Before 2026

The approaching expiration of TCJA provisions creates a narrow window for strategic tax planning. Small businesses that act proactively can minimize the impact of these changes and position themselves for success under the new tax environment.

Income timing strategies become particularly important in 2025. Businesses with flexibility in their revenue recognition may benefit from accelerating income into 2025 to take advantage of the Section 199A deduction one final time. Conversely, businesses expecting lower income in 2026 might benefit from deferring deductible expenses until the higher tax rate environment takes effect.

Business structure evaluation is another critical consideration. The elimination of the Section 199A deduction may make C corporation status more attractive for some businesses, particularly those with retained earnings and growth plans. However, this decision requires careful analysis of the long-term implications, including potential double taxation issues.

Year-End 2025 Planning Priorities

Small businesses should focus on these key areas during 2025 planning:

1. Model tax liability under both current and post-2025 tax rules
2. Evaluate equipment purchase timing to maximize remaining bonus depreciation
3. Consider accelerating income or deferring expenses based on rate changes
4. Review business entity structure for potential optimization opportunities
5. Assess retirement plan contributions and other tax-advantaged strategies
6. Update financial projections to account for higher effective tax rates
7. Consider multi-year tax planning strategies that span the transition period

The complexity of these decisions often requires sophisticated modeling and professional guidance. Small businesses should begin these conversations with their tax advisors early in 2025 to allow sufficient time for analysis and implementation of optimal strategies.

Technology and Software Preparation for New Tax Requirements

The changing tax landscape requires small businesses to evaluate their accounting and tax preparation technology to ensure compliance with new requirements. As depreciation schedules become more complex and deduction calculations change, having robust systems in place becomes increasingly important.

Cloud-based accounting solutions offer particular advantages during periods of tax law transition. These systems typically receive updates automatically, ensuring that depreciation schedules, deduction calculations, and tax forms reflect the most current requirements. This is especially valuable for small businesses that may not have dedicated tax professionals monitoring every regulatory change.

Sagenext provides cloud hosting solutions for popular accounting and tax software, ensuring that small businesses have access to the most current versions of their critical business applications. This approach eliminates concerns about software updates and provides the reliability needed during complex tax transitions.

For businesses using QuickBooks Desktop, cloud hosting through QuickBooks Hosting services ensures access to the latest tax forms and depreciation schedules without the burden of managing local software installations and updates.

Technology Upgrade Considerations

Small businesses should evaluate several technology factors as they prepare for 2026 tax changes:

• Ensure accounting software can handle complex depreciation schedules without bonus depreciation
• Verify that tax preparation software includes updated forms and calculations for 2026
• Consider cloud-based solutions that provide automatic updates and improved accessibility
• Evaluate integration between accounting systems and tax preparation software
• Assess backup and security measures for critical financial data
• Plan for staff training on new software features and tax calculation methods

The transition period also presents an opportunity to evaluate whether current technology solutions meet the business’s evolving needs. Businesses that have been considering upgrades to their accounting or tax preparation systems may find that implementing these changes before the 2026 tax year provides additional time to adapt to new workflows.

Frequently Asked Questions

What tax deductions will small businesses lose in 2026?

Small businesses will lose several key deductions when TCJA provisions expire at the end of 2025. The most significant loss will be the Section 199A qualified business income deduction, which currently allows eligible pass-through entities to deduct up to 20% of their qualified business income. Additionally, bonus depreciation will be eliminated for property placed in service after 2026, requiring businesses to return to traditional depreciation schedules. Interest deduction limitations will also become more restrictive, and various other business deductions that were enhanced under the TCJA will revert to pre-2018 levels.

How will the Section 199A deduction change in 2026?

The Section 199A deduction will be completely eliminated for tax years beginning after December 31, 2025. This means that pass-through entities including sole proprietorships, partnerships, S corporations, and LLCs will no longer be able to claim the up to 20% deduction on qualified business income. For eligible businesses, this represents a significant increase in effective tax rates. A business owner who previously qualified for the full 20% deduction will see their top marginal rate on business income increase from 29.6% to 37%, assuming they’re in the highest tax bracket.

When should small businesses start preparing for 2026 tax changes?

Small businesses should begin preparing for 2026 tax changes immediately, with intensive planning throughout 2025. The key planning window is the 2025 tax year, as this represents the final opportunity to take advantage of expiring TCJA provisions. Businesses should start by modeling their tax liability under both current and post-2025 rules to understand the financial impact. Strategic decisions about income timing, equipment purchases, and business structure should be made well before December 31, 2025, to maximize benefits from expiring provisions. Working with tax professionals early in 2025 allows sufficient time for analysis and implementation of optimal strategies.

The 2026 tax law changes small business owners will face represent some of the most significant shifts in tax policy in recent years. From the elimination of the Section 199A pass-through deduction to the complete phase-out of bonus depreciation, these changes will fundamentally alter how small businesses approach tax planning and financial management.

Success in navigating these changes requires proactive planning, strategic decision-making, and the right technology infrastructure. Small businesses that begin preparing now will be better positioned to minimize the impact of higher tax rates and maintain their competitive advantage in the post-TCJA environment.

The complexity of these transitions underscores the importance of having reliable, up-to-date accounting and tax preparation systems.
