Since the earliest online report (2013)
Compares the 2013 report with the 2025 report, using the same method for both. He first served in the House from 2008 to 2011. His first report in the online database covers 2013, the year he returned to office, so we can't show his wealth from his first stint. Changes can come from a spouse’s assets, market moves, property values, new debts or how filers choose bands, and the forms do not say which. We do not guess.

Where the money comes from
Main sources named in the disclosures and the reporting we cite. The forms don’t split the total into exact amounts, so we don’t show percentages.
Bill Foster reported household assets minus debts of $11.2M to $32.2M, a midpoint of about $21.7M, on his latest financial disclosure (2025 annual report, filed April 18, 2026).
Bill Foster has represented Illinois's 11th congressional district, in Chicago's western and southwestern suburbs, since 2013. He first served in the House from 2008 to 2011, representing the 14th district. He is a member of the Democratic Party.
Foster is a physicist and businessman. Disclosures shown here begin after his return to the House, so the first report on this page comes from his current period in office.
What his 2025 disclosure shows
The report he filed on April 18, 2026 covers 2025. It lists 41 assets with a value, adding up to $11.2 million to $32.2 million. The largest are CREF Stock Fund ($1M–$5M); Invesco National AMT-Free Municipal Bond ETFo (PZA) (joint, $1M–$5M) and Vanguard Information Tech ETF (VGT) (joint, $1M–$5M). Another two items are listed with no value or an undetermined value, such as a pension, so they are not counted.
The report lists no debts that we count, so the range of $11.2 million to $32.2 million comes from the assets alone, with a midpoint of about $21.7 million.
How the range has changed
Using the same method for every year, the midpoint of his disclosed range went from about $18.8 million on his 2013 report to about $21.7 million on his 2025 report. The highest midpoint was about $22.6 million, on the 2017 report. The lowest was about $14.1 million, in 2018. The chart shows 13 reports from 2013 to 2025, each added up the same way, and nothing is filled in between them.
These are ranges built from the value bands on each form, not exact values. They move with market prices, property values, new or paid-off debts and the bands a filer picks, and the forms do not say which of these caused a change. Like every member of Congress, Foster does not have to report a home he lives in, cars and personal belongings, or federal retirement savings such as the Thrift Savings Plan, so his real net worth could be higher than these forms show.
