Year-End Tax Considerations for Dealerships: What to Review Before Closing Out 2025

As dealerships prepare to close their books for 2025, tax strategy becomes just as important as sales performance. The final weeks of the year bring opportunities to reduce tax liability, strengthen financial positions, and enter 2026 with clearer visibility and fewer surprises. But dealership tax planning is complex, with inventory rules, floorplan interest considerations, evolving bonus depreciation rules, and manufacturer programs all influencing year-end decisions.

A proactive review now can help dealerships optimize their tax position and avoid rushing through critical decisions in the final days of December. Here are the key areas dealerships should focus on as the year comes to a close.

Review Bonus Depreciation and Section 179 Before Year-End

2025 brings continued changes in bonus depreciation rules, and dealerships need to evaluate how year-end equipment and facility investments will be treated. While bonus depreciation had been phasing down in recent years, 100 percent bonus has been reinstated by the One Big Beautiful Bill for assets acquired and placed in service after January 19, 2025. In addition, Section 179 may provide meaningful opportunities depending on your entity structure and acquisition limits.

A year-end equipment or technology purchase shouldn’t be made just for tax reasons, but if upgrades are already planned, timing them correctly can create tax efficiencies. This is especially relevant for dealerships with aging diagnostic tools, shop equipment, or IT infrastructure.

Evaluate LIFO Considerations and Inventory Levels

LIFO continues to be a significant tax tool for dealerships, but 2025 inventory conditions remain uneven across manufacturers. Some dealerships have returned to more normal inventory levels, while others are still facing volatility depending on manufacturer pipelines.

Important year-end questions include:

• Are LIFO reserves likely to unwind based on 2025 inventory changes?
• How will year-end acquisitions, inventory purchases, or returns impact LIFO layers?
• Is a LIFO conformity review necessary before issuing financial statements?

Even small shifts in year-end inventory levels can have material tax implications, especially in years with price fluctuations or manufacturer allocation inconsistencies.

Assess Floorplan Interest and Limitations

Interest rates remain elevated, and floorplan interest continues to have a major impact on dealership profitability. While dealerships receive a full deduction on floorplan interest, interest limitations tied to adjusted taxable income may affect certain dealerships depending on their structure and earnings profile.

Year-end is the ideal time to project:

• Whether floorplan interest will exceed allowable deductions
• How bonus depreciation decisions affect the interest limitation
• Whether different entity structures or elections may be beneficial

The interaction between interest deductions and depreciation strategy can be one of the most important year-end planning considerations.

Analyze Manufacturer Incentive Timing

Manufacturer incentive programs can significantly influence taxable income depending on when payments are earned or received. In a year where incentive programs have become more complex, timing matters.

Key items to review include:

• Whether year-end incentives will be recognized in 2025 or 2026
• Compliance documentation to support incentive recognition
• Open co-op or facility program reimbursements that may hit year-end revenue
• Accounting treatment for stair-step or volume-based programs

Dealerships should confirm timing before the year closes to avoid unexpected income recognition.

Review Repair Order Documentation for Warranty and Tax Compliance

Warranty reimbursements, internal work, and customer-pay service all impact revenue classification and tax treatment. Year-end is an appropriate time to evaluate whether documentation supports the deductions claimed and whether repair order processes comply with both manufacturer and IRS standards.

With service departments growing as a portion of dealership profitability, clean documentation helps ensure the tax return accurately reflects operations, and reduces audit risk.

Confirm Payroll, Compensation, and Ownership Distributions

With many dealerships experiencing leadership changes, expanded incentive programs, or performance bonuses in 2025, compensation structures may need a year-end review. This includes:

• Reasonable compensation standards for owners
• Bonus accruals and timing
• Retirement plan contributions and eligibility
• S-corp or partnership distributions

Addressing these items early prevents rushed adjustments in the final week of the year.

Consider Whether 2025 Is the Right Time for Entity or Structural Changes

While major restructuring should not be rushed into year-end, dealerships that are already evaluating ownership transitions, expansion, or succession should consider whether certain actions need to be initiated before December 31.

This includes:

• Updating entity structures
• Adjusting ownership percentages
• Beginning or finalizing succession-driven transfers
• Reviewing estate and gift planning opportunities

Even a preliminary conversation in December can provide clarity before 2026 begins.

Finalize Tax Estimates and Cash Flow Planning

A year-end tax projection is essential for dealerships, especially in a year with fluctuating inventory costs, incentive programs, and interest expenses. Understanding your estimated liability early helps avoid surprises and provides time to plan cash needs appropriately.

A December projection should incorporate:

• Updated net income
• Inventory adjustments
• Expected incentives
• Depreciation decisions
• Any potential credits or deductions that will expire with the year

Cash planning is sometimes overlooked, but it’s one of the most beneficial steps dealerships can take before year-end.
