As spring arrives in March 2026, small business owners face a critical window to optimize their positions amid significant 2026 tax changes. Consequently, understanding the One Big Beautiful Bill Act (OBBBA) provisions is essential for maximizing your financial strategy before the first quarterly deadline.
For businesses in the Inland Empire and beyond, these updates offer a unique opportunity to secure thousands in savings. As your trusted CPA Moreno Valley partner, we break down exactly how to navigate this new landscape.
Essential Takeaways
- Permanent restoration of 100% bonus depreciation drives immediate tax savings.
- Section 179 limits have increased substantially to $2.56 million for 2026.
- Critical deadlines and compliance rules require proactive tax preparation planning.
Navigating the 2026 Tax Changes Landscape
The 2026 tax year represents a significant turning point for small businesses. Specifically, the OBBBA, passed in July 2025, brought substantial 2026 tax changes that took effect on January 1. Unlike previous years filled with temporary provisions and expiring deductions, many of these adjustments offer permanent tax relief and greater planning certainty.
For Catalyst CPA clients and Riverside County CPA seekers, spring is the ideal time to review your strategy. Assessing eligibility for new deductions now ensures you remain on track with payment obligations.
Quarterly Deadlines and 2026 Tax Changes
One of the most critical spring obligations is the first quarterly estimated tax payment due April 15, 2026. If you are self-employed or run a business with variable income, understanding 2026 tax deadlines is essential to avoid penalties.
2026 Payment Schedule Overview
| Quarter | Deadline |
|---|---|
| Q1 2026 (Jan 1 – Mar 31) | April 15, 2026 |
| Q2 2026 (Apr 1 – Jun 30) | June 15, 2026 |
| Q3 2026 (Jul 1 – Sep 30) | September 15, 2026 |
| Q4 2026 (Oct 1 – Dec 31) | January 15, 2027 |
According to IRS guidelines, you should make payments if you expect to owe $1,000 or more. Furthermore, high earners with AGI over $150,000 must pay 110% of last year’s liability to be safe.
Critical Alert: Mark these dates now. Missing a quarterly payment can result in penalties even if you expect a refund later.
Section 179 Expensing Under 2026 Tax Changes
Perhaps the most significant of the 2026 tax changes involves Section 179 expensing. This powerful deduction allows you to deduct the full price of qualifying equipment immediately.
Expanded Limits for Growth
The OBBBA made substantial improvements to help small businesses grow:
- Maximum Deduction: Increased to $2.56 million (up from $2.5 million).
- Phase-out Threshold: Raised to $4.09 million.
- Eligibility: Expanded for businesses spending less than $6.65 million.
Financial experts note that these changes allow businesses to deduct more capital purchases upfront. This strategy significantly improves cash flow for growing companies investing in their future.
Eligible Property Types
Section 179 applies to diverse business property, including software, heavy vehicles, and office equipment. However, remember that vehicles follow stricter rules regarding business use percentages and mileage logs.

Permanent 100% Bonus Depreciation Benefits
One of the most welcome OBBBA tax provisions was the restoration of 100% bonus depreciation. This rule allows businesses to deduct the entire cost of qualifying property immediately, with no phase-down schedule.
According to Thomson Reuters, this applies to property acquired after January 19, 2025. When combined with Section 179, you may deduct up to 100% of purchases in a single year.
Strategic Order of Deductions
The IRS requires a specific application order for these deductions:
- First, elect Section 179 deductions.
- Then, apply bonus depreciation.
- Finally, use MACRS depreciation for any remaining basis.
Additional 2026 Tax Changes for Owners
Beyond expensing, other 2026 tax changes impact your broader financial picture.
Retirement and Reporting Updates
Retirement contribution limits have risen, with 401(k) limits hitting $24,500. Additionally, new reporting requirements for tips and overtime on W-2s demand strict bookkeeping services compliance. Accurate payroll reporting is now more critical than ever.
Moreover, the business interest deduction has been restored to the EBITDA standard. This change provides flexibility for businesses carrying significant debt, especially in real estate.

- Review Q1 Income: Determine if estimates need adjustment.
- Assess Capital Spend: Plan purchases to leverage deductions.
