According to the Biden's 2023 tax return, Joe Biden made $400,000 for being president and Jill Biden made $86,000 as a professor at Northern Virginia Community College. Most of the Bidens' net worth, an estimated $7 million of their $10 million, comes from their two Delaware homes.

While serving as First Lady, Dr. Biden continued teaching English and writing at Northern Virginia Community College, where she has been a professor since 2009. She is the first presidential spouse to maintain an independent career outside of the White House. “Teaching isn't just what I do, it's who I am.”

The president's son refers to Jill Biden as "my mother" in his memoir of drug addiction, but the Biden family's public story really begins with the tragedy of Joe Biden's first wife, Neilia Hunter Biden.
