Little is known about the effects of accounting regulation on private insurers. In this paper, we examine the uniqueness of the tax deductibility of insurers’ loss accruals. We find that private insurers’ overstatement of loss accruals in tax planning significantly decreases after adoption of the Statement of Statutory Accounting Principles (SSAP) 101, which mandates that insurance companies recognize and measure tax contingencies. Relative to public insurers’ loss reserve errors, those of private insurers decrease by an estimated 0.8–1.1 percent of total assets, implying a forfeited tax benefit of $1.79–$4.4 million per firm, per year. We also find that the decrease is mitigated for insurers with lower IRS monitoring or in states where the insurance industry comprises a greater part of state employment. Additionally, insurers with independent boards, or those with independent, external actuaries are more responsive to the adoption of SSAP 101.
