(1)     State taxes in Connecticut (for CL&P), Massachusetts (for NSTAR Electric) and New Hampshire (for PSNH) made up the majority of the tax effects in this category for Eversource.
Eversource maintains a valuation allowance recorded on deferred tax assets associated with the loss recorded from the offshore wind investments. In the third quarter of 2025, as part of filing its 2024 tax return to provision process, Eversource partially reversed this valuation allowance by $294 million and also recorded a charge of $129 million as it reconciled the positions on the tax return to what was estimated as of December 31, 2024, resulting in a net benefit of $165 million to tax expense. The adjustment to the valuation allowance was required based on the reconciling of previously recorded tax losses to amounts included in applicable partnership income tax returns. Both adjustments resulted from changes in tax estimates based on information from the partnership tax returns received in the third quarter of 2025. Eversource also recognized state tax benefits and certain tax credits of $118 million as part of the 2024 tax return to provision process. These benefits totaling $283 million were recorded as a reduction to income tax expense on the statement of income in 2025. The Loss on Offshore Wind in the table above of $59.5 million reflects the federal impacts of the $129 million charge, partially offset by the tax benefit of $44 million recorded from the pre-tax increase of $284 million to the offshore wind contingent liability recorded in the third quarter of 2025.

Eversource, CL&P, NSTAR Electric and PSNH file a consolidated federal income tax return and unitary, combined and separate state income tax returns.  These entities are also parties to a tax allocation agreement under which taxable subsidiaries do not pay any more taxes than they would have otherwise paid had they filed a separate company tax return, and subsidiaries generating tax losses, if any, are paid for their losses when utilized.
Deferred tax assets and liabilities are recognized for the future tax effects of temporary differences between the carrying amounts and the tax basis of assets and liabilities.  The tax effect of temporary differences is accounted for in accordance with the rate-making treatment of the applicable regulatory commissions and relevant accounting authoritative literature.  The tax effects of temporary differences that give rise to the net accumulated deferred income tax obligations are as follows:

Interest and Penalties:  Interest on uncertain tax positions is recorded and generally classified as a component of Other Interest Expense on the statements of income.  However, when resolution of uncertainties results in the Company receiving interest income, any related interest benefit is recorded in Other Income, Net on the statements of income.  No penalties have been recorded. The amount of interest expense recognized on uncertain tax positions was $2.4 million, $1.3 million and $0.3 million for the years ended December 31, 2025, 2024, and 2023, respectively. Accrued interest payable was $4.1 million and $1.7 million as of December 31, 2025 and 2024, respectively.

Tax Positions:  During 2025 and 2024, Eversource did not resolve any of its uncertain tax positions.

About Income Taxes Disclosures

The income tax disclosure reveals how much a company actually pays in taxes versus what the statutory rate would predict. Analysts focus on the effective tax rate (ETR) reconciliation, which breaks down every item driving the gap between the 21% federal rate and the company's reported ETR — including R&D credits, foreign rate differentials, and state taxes. Deferred tax assets (DTAs) and their valuation allowances signal management's confidence in future profitability: a rising allowance suggests the company doubts it can use accumulated tax benefits. Uncertain tax benefit (UTB) reserves quantify exposure to IRS challenges on aggressive positions.

Key signals to watch: sudden ETR drops without clear operational reasons, large increases in valuation allowances, growing UTB balances, and significant unremitted foreign earnings. Post-TCJA, pay attention to GILTI and BEAT provisions that affect multinational tax structures. Compare the cash taxes paid (from the cash flow statement) against the income tax provision to gauge earnings quality.
