A breakdown of the data by the real estate blog roofline.com reveals that the median property taxes paid last year by New York City residents was $5,633 compared to the national median of $2,578. Residents of three cities had stiffer tax bills: Elizabeth, N.J. (nearly $9,000); San Francisco ($7,678); and Austin, Tex., ($6,616). Adding to the sting was the Trump administration’s tax bill, which, beginning in 2018, began limiting the amount of state and local taxes that can be deducted against federal income taxes. As a result, living in expensive, high-tax states such as New York, New Jersey and Illinois became even more expensive.
