Tax Strategy & Considerations
Tax Profile:
- Effective Tax Rate: 20.9% in 2025, compared to 21.6% in 2024. The 2025 rate was slightly lower than the 21% federal statutory rate due to a $30.5 million credit for increasing research activities (R&D tax credit), partially offset by $30.3 million of net state income taxes.
- Geographic Tax Planning: The Company conducts business across virtually all U.S. states, influencing its effective tax rate based on varying state tax rates and rules.
- Tax Reform Impact: The One Big Beautiful Bill Act, enacted July 4, 2025, reinstated immediate expensing of domestic R&E expenditures, 100% bonus depreciation, and terminated the energy-efficient commercial buildings deduction. These provisions are not expected to materially affect the Company's operating results, cash flows, or financial condition.
- Tax Refunds: In April 2025, the Company received a $107.1 million refund for its 2022 federal tax overpayment, along with $11.3 million (or $8.9 million, net of tax) in interest income, which reduced its provision for income taxes in the first quarter of 2025.
Insurance & Risk Transfer
Risk Management Framework: Comfort Systems USA, Inc. is substantially self-insured for workers’ compensation, employer’s liability, auto liability, general liability, and employee group health claims, due to high per-incident deductibles. The Company manages these risks primarily through its wholly owned captive insurance company. Loss estimates for larger and longer-developing risks are reviewed quarterly by a third-party actuary. Insurance Coverage: The Company generally retains the first $500,000 per occurrence for losses under individual lines, with reinsurance providing additional risk transfer for subsequent large losses. Most insurance policies are renewed annually, and terms may change. Risk Transfer Mechanisms: The Company frequently posts performance and payment bonds issued by sureties, which provide assurance to customers. The Company must reimburse sureties for any expenses incurred. As collateral for potential obligations under bonds, the Company grants sureties a first lien on assets such as receivables, costs and estimated earnings in excess of billings, and equipment specifically identifiable to bonded projects. As of December 31, 2025, the book value of these assets was approximately $258.4 million.
