2025 Year-End Tax Planning Strategies for Business Owners

Below is a curated set of tax planning strategies for business owners to consider before year-end under the 2025 regime.

1. Review Corporate Structure and Tax Status

The way your entity is structured (sole proprietorship, partnership, or corporation) continues to have a profound impact on your tax outcomes. With looming changes to individual and corporate tax policies, now is a good time to revisit whether your current structure remains optimal.

Key considerations:

• Future tax rate risks. High earners may see shifts in individual tax rates, and corporate tax rates might be adjusted in future legislation.
• Dividend taxation. The favorable tax rates on qualified dividends may come under pressure; re-characterizing distributions, or timing dividends, could become more relevant.
• State tax considerations. Differences in state tax regimes may lead you to re-evaluate your state of incorporation or where operations are located.

Before making any structural change, consult both your tax advisor and corporate counsel; what works today might not be optimal under next year’s rules.

2. Review and Max Out Retirement Plan Options

Retirement plans remain one of the most powerful levers to reduce current taxable income while funding your future.

• Max contributions: Make sure you (and your employees) are contributing up to allowable limits. For 2025, verify the IRS caps for 401(k), SEP, SIMPLE, and profit-sharing plans.
• Roth vs pretax: If your tax rate today is lower than what you anticipate in retirement, allocate a portion of contributions to Roth options when available.
• Employer credits: Smaller businesses can still benefit from tax credits for setting up new retirement plans or auto-enrollment features.
• SECURE Act / SECURE 2.0 compliance: Stay current with changes under these acts – e.g., Roth catch-up rules, required minimum distributions, and allowed flexibility in plan features.

Align your strategy to reduce your current tax burden and position for growth in retirement.

3. Business Transition Planning

Planning for the eventual exit or transition of your business should begin long before the actual event. Without planning, owners risk leaving value on the table or creating disagreements among heirs.

• Succession options: Selling to co-owners, passing to family members, or selling to an outside buyer — each path requires tailored planning (buy-sell agreements, redemption agreements, etc.).
• Insurance & funding: Ensure that life insurance, disability coverage, or other buy-out funding mechanisms are adequate and structured properly.
• Periodic review: Revisit your succession plan annually (or whenever significant events occur, such as changes in ownership, business valuation, or personal circumstances).

If you haven’t yet, now is an opportune time to bring in advisors to help architect a plan aligned with your legacy goals.

4. Take Advantage of the Business Expensing Election (Section 179)

Section 179 continues to provide an accelerated deduction for qualifying property placed in service during the tax year. For 2025:

• Deduction cap & phase-out. The maximum deduction and the beginning of the phase-out threshold are adjusted for inflation each year. Be sure to check the 2025 IRS limits.
• Eligible property. The deduction applies not only to new equipment, but also to some types of used property, and expanded definitions may allow deductions for qualified improvements to nonresidential real property (e.g., HVAC, fire protection, interior improvements).
• Timing matters. Assets placed in service by December 31 qualify. Even purchases late in the year may still be fully deductible under Section 179 rather than waiting for 2026.

Using the Section 179 election can lower taxable income today and enhance your cash flow.

5. Don’t Forget Bonus Depreciation — It’s Back Baby!

In a welcome development, bonus depreciation has been fully restored to 100% by recent legislation (often referred to colloquially as the “Big Beautiful Bill”). This means that for qualifying property placed in service in 2025, you can expense the entire cost immediately, rather than amortizing it over its useful life.

Key points for 2025 and beyond:

• Permanent 100% deduction. The prior law had bonus depreciation phasing down to 0% after 2026, but OBBBA made 100% bonus depreciation a permanent part of the tax code.
• Applies to new and used property. As long as the property is acquired and placed in service during the year, it qualifies.
• Full deduction up front. No proration – 100% of the purchase price is deductible in year one.
• Works with Section 179. Business owners can coordinate bonus depreciation with Section 179, expensing to maximize tax benefits. However, ordering and planning are critical to avoid wasted deductions.

If you have equipment, machinery, or qualified assets on your radar, accelerating their acquisition to 2025 might yield substantial tax savings.

6. Maximize the Pass-Through (QBI) Deduction

One of the most significant shifts for business owners in 2025 is the treatment of the Qualified Business Income (QBI) deduction under the new One Big Beautiful Bill Act (OBBBA).

• Now permanent: The QBI deduction is no longer scheduled to expire after 2025. This provides stability and long-term planning certainty for pass-through entity owners.
• Expanded phase-in thresholds: The OBBBA increased the income phase-in ranges where wage/property limitations and specified service trade or business (SSTB) restrictions apply. For 2025, the phase-in range is now $75,000 for single filers and $150,000 for joint filers (indexed for inflation starting in 2026). This allows more high-income taxpayers, particularly those in service fields, to qualify for at least a partial deduction.
• New minimum deduction: If you generate at least $1,000 of aggregate QBI from active, materially-participated businesses, you are guaranteed a minimum deduction of $400 (indexed for inflation after 2026). This ensures small but active businesses receive a benefit, even when income is modest.
• Core rules remain: The deduction still equals the lesser of (a) 20% of QBI (plus 20% of qualified REIT dividends and PTP income) or (b) 20% of taxable income (less net capital gain). It is only available to non-corporate taxpayers, and wage/property limitations still apply, but will impact fewer taxpayers due to the higher thresholds. Importantly, the reinstated Pease limitation on itemized deductions (starting in 2026) will not affect QBI.

7. Leverage Energy-Related and R&D Credits

Tax credits continue to reward investments in clean energy and innovation. However, most energy-related tax credits will not be available after 2025 unless Congress extends them. That means 2025 may represent a peak window to benefit.

Energy-related credits:

• Clean energy investments. Credit programs for solar, wind, geothermal, and energy storage may be winding down post-2025.
• Commercial buildings/efficiency credits. Incentives for green building improvements, energy audits, and efficiency upgrades are likely subject to sunset.
• Alternative fuel vehicle credits. Credits for electric or hydrogen fuel cell vehicles may face phaseouts depending on legislative renewal.

Because many energy credits may vanish or shrink after 2025, now is the time to evaluate whether your business can deploy capital into qualifying clean energy assets.

R&D (Research & Development) credits:

• Continuing availability. The R&D credit remains a valuable incentive for businesses engaged in innovation – developing new or improved products, processes, or software.
• Small business election. Qualified small businesses can elect to apply the credit against payroll tax liability (up to a limit), providing relief even if the entity is not currently profitable.
• Credit stacking and eligibility. Work with your tax advisor to determine stacking with other credits or grants, and to ensure eligible costs are correctly characterized (i.e., wages, supplies, contract research).

Given the impending expiration risk of many energy credits, aligning your capital investment decisions today may preserve significant tax advantages you won’t get later.

8. Review Your Compensation Strategy

Your compensation decisions, both for yourself and your employees, can shift significant tax outcomes. As year-end approaches:

• Bonuses and profit-sharing. If your business is profitable, carve out bonus or profit-sharing payments before December 31 to deduct them in 2025.
• W-2 wages. For pass-through businesses aiming to boost QBI deduction eligibility (or satisfy wage limits), strategically increasing W-2 wages may pay dividends.
• Distributions vs salary. In S corporations, the split between distributions and salary remains closely scrutinized. Review your balance to ensure IRS compliance and tax optimization.
• Deferred compensation. If your business maintains a deferred compensation arrangement, carefully assess the timing and recognition triggers in light of expected tax changes.

Aligning compensation planning late in the year can help optimize deductible expenses, QBI outcomes, and cash flow.

9. Defer Income and Accelerate Deductions (When Appropriate)

Classic year-end moves remain evergreen, though in light of changing rules, their importance is magnified.

• Defer invoices: If your cash-based business can push invoicing into early 2026, that defers income recognition.
• Prepay expenses. Paid in 2025, but related to 2026 operations (insurance, rent, etc.) may allow deductible acceleration, subject to applicable rules.
• Accelerate purchases. Bring forward the acquisition of eligible equipment or supplies that qualify under Section 179 or bonus depreciation.
• Review accrual-basis strategies. For accrual taxpayers, carefully consider when to accrue or delay expenses in light of deductions and timing.

Because of the potential for legislative changes after 2025, strategies that defer income today may provide an outsized benefit.

Final Thoughts

2025 is not just another year-end for tax planning; it’s a turning point. Thanks to the One Big Beautiful Bill Act (OBBBA), two of the most powerful provisions for small business owners – the QBI deduction and 100% bonus depreciation – are now permanent parts of the tax code. That means you can plan with greater certainty, knowing these benefits won’t vanish after 2025.

At the same time, many energy-related tax credits are set to expire, and other rules (like individual rate changes and deduction limits) may shift in the coming years. Acting now to capture what’s available, while positioning your business for the long haul, is essential.
