Allstate Protection underwriting income was $3.04 billion in the third quarter of 2025 compared to underwriting income of $555 million in the third quarter of 2024, due to lower catastrophe losses, increased premiums earned and the benefit of prior year reserve releases. Underwriting income totaled $4.69 billion in the first nine months of 2025 compared to underwriting income of $1.32 billion in the first nine months of 2024, due to increased premiums earned and the benefit of prior year reserve releases, partially offset by higher expenses.

Previous report

income tax expense of $1.80 billion on total income from operations before income tax expense of $8.24 billion. The effective rate for the first nine months ended September 30, 2025, is higher than the federal statutory rate of 21%, primarily due to non-deductible goodwill and higher state income taxes arising from the sales of the EVB and group health businesses, offset by tax benefits derived from tax credits, tax-exempt interest income and share-based payments.

Previous report

For the first nine months ended September 30, 2024, we reported an effective tax rate of 18.2% based on a total income tax expense of $603 million on income from operations before income tax benefit of $3.31 billion.
