How to read this: members of Congress report each asset and debt in a value band (for example, $1,001 to $15,000), not an exact amount. We add up the low ends and the high ends, then subtract debts the same way, to get the widest possible range. The midpoint is simply the middle of that range, not a measured value. The forms do not include a home the official lives in (unless it earns rent), cars and personal belongings, or federal retirement savings such as the Thrift Savings Plan, so true net worth can be higher.

Compares the 2014 report with the 2025 report, using the same method for both. He took office in 1999. The House's online database has his electronic reports from 2014 on, so we can't show his wealth when he first took office. 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

Congressional salaryStocks

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.

Mike Simpson reported household assets minus debts of $1.59M to $3.3M, a midpoint of about $2.45M, on his latest financial disclosure (2025 annual report, filed April 14, 2026).

Mike Simpson has represented Idaho's 2nd congressional district since 1999. The district covers most of eastern Idaho, including Idaho Falls, Pocatello, Twin Falls and most of Boise.

He served in the Idaho House of Representatives from 1984 to 1998 and was its Speaker from 1992 to 1998. He is a member of the Republican Main Street Partnership and was first elected to Congress in 1998.

What his 2025 disclosure shows

The report he filed on April 14, 2026 covers 2025. It lists 10 assets with a value, adding up to $1.6 million to $3.3 million. The largest are D.A. Davidson/Stifel: Stifel Financial Corporation Common Stock (SF) ($500K–$1M); D.A. Davidson/Stifel: Stifel Financial Corporation Common Stock (SF) ($500K–$1M) and American Estate & Trust (Accuplan): American Estate & Trust ($250K–$500K).

The report lists no debts that we count, so the range of $1.6 million to $3.3 million comes from the assets alone, with a midpoint of about $2.4 million.

How the range has changed

Using the same method for every year, the midpoint of his disclosed range went from about $1.7 million on his 2014 report to about $2.4 million on his 2025 report. The highest midpoint was about $2.7 million, on the 2021 report. The lowest was about $1.2 million, in 2024. The chart shows twelve reports from 2014 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, Simpson 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.
