December 11, 2025 | Economics and Other
This research brief computes 2023 county-level effective tax rates (ETRs) as the ratio of personal income tax liability to total income. Total income includes both taxable and non-taxable income (e.g., Social Security, pensions, SNAP benefits). Counties surrounding Philadelphia (Chester, Montgomery, Bucks and Delaware) had some of the highest ETRs, while rural counties (Forest, Cameron, Sullivan and Venango) had the lowest ETRs.
