Income Tax Expense and Rate

EXXON MOBIL CORP · 2026-05-04 · Importance 66 · Surprise 74 · From source text

Income tax expense was $2,495 million for the first quarter, down from $3,567 million in the prior-year quarter, a decrease of approximately $1,072 million (about 30%). The effective income tax rate was 40 percent in the quarter, 6 percentage points higher than the prior-year period, driven by portfolio mix effects impacted by derivative mark-to-market losses. Total taxes and duties were $9,270 million for the quarter, down $1,363 million year-over-year. The combination of lower income tax expense but a higher effective rate indicates shifts in taxable income mix and significant non-operational mark-to-market impacts on tax calculations.
