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. We also leave out mortgages on homes the report does not list as assets, because the homes themselves are not counted either.

Compares the 2013 report with the 2025 report, using the same method for both. Her first report in the online database covers 2013, the year she 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.

Katherine Clark reported household assets minus debts of $6.82M to $21.2M, a midpoint of about $14M, on her latest financial disclosure (2025 annual report, filed May 15, 2026).

Katherine Clark has represented Massachusetts's 5th congressional district, which covers cities and suburbs north and west of Boston, since a 2013 special election. She has been House Democratic whip since 2023, after serving as assistant speaker and as vice chair of the Democratic Caucus.

Born in Connecticut, she worked as a lawyer before moving to Massachusetts in 1995. She served on the Melrose School Committee and then in the Massachusetts House and Senate before winning the seat left open by Ed Markey.

What her 2025 disclosure shows

The report she filed on May 15, 2026 covers 2025. It lists 57 assets with a value, adding up to $7.1 million to $21.3 million. The largest are Family Home (non-primary) (Truro, MA) (joint, $1M–$5M); Judith S. Clark Irrevocable Trust: SPDR S&P 500 (SPY) ($1M–$5M) and DC Co-op (Washington, DC) (joint, $500K–$1M). Another twelve items are listed with no value or an undetermined value, such as a pension, so they are not counted.

On the debt side, the report lists one debt, a co-op building loan with Capitol Hill Tower Housing, held jointly, in the $100K–$250K band. Subtracting debts the same way gives a range of $6.8 million to $21.2 million, with a midpoint of about $14 million. It also lists a mortgage on a home the report does not list as an asset. As on all our House profiles, we leave that debt out because the home's value is not counted either.

How the range has changed

Using the same method for every year, the midpoint of her disclosed range went from about $2.9 million on her 2013 report to about $14 million on her 2025 report. 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, Clark does not have to report a home she lives in, cars and personal belongings, or federal retirement savings such as the Thrift Savings Plan, so her real net worth could be higher than these forms show.
