State Rep. Tram Nguyen, who represents Andover, North Andover, Boxford, and Tewksbury in the Massachusetts House, publicly released five years of personal tax returns on Friday, July 24, and challenged her five Democratic opponents in the MA-6 congressional race to do the same before the September 1 primary.

Nguyen's campaign says she is the first announced candidate in the six-way race to release multiple years of returns. None of her rivals had disputed that claim or responded to the challenge as of Friday evening. She disclosed returns covering tax years 2021 through 2025.

The numbers paint a picture of a public servant's salary. Nguyen's individual income ranged from $82,056 in 2021 to $96,009 in years she filed alone, according to her campaign. In 2025, she and her husband, a mechanical engineer, filed jointly and reported combined income of $232,038. The couple paid more than $33,000 in federal income taxes and more than $11,000 in Massachusetts income taxes that year.

"My opponents shouldn't have any trouble meeting this minimum transparency standard, particularly those who are eagerly using their insider connections and personal wealth to fund their campaigns," Nguyen said in a statement released Friday.

The challenge comes in a race where money has been a defining fault line. Dan Koh, a former chief of staff to Boston Mayor Marty Walsh, has raised more than $4.5 million total, including more than $1 million in the second quarter alone, according to Andover News reporting on FEC filings. John Beccia, a financial technology executive from Lynnfield, has self-funded roughly $2 million of his $2.4 million war chest, according to the Marblehead Independent. Nguyen, by contrast, has raised more than $690,000 from 2,827 individual donors, with more than 80% of contributions coming from Massachusetts and a median gift under $25, her campaign says.

The other candidates in the Democratic primary are Beth Andres-Beck, Mariah Lancaster, and Jamie Zahlaway Belsito.

The seat opened when Rep. Seth Moulton announced his run for U.S. Senate. The winner of the Tuesday, September 1 Democratic primary will face Republican Micah Jones in the November general election. All three major race-rating outlets rate the district Solid or Safe Democratic.

A July internal poll commissioned by the Beccia campaign showed Beccia at 15%, Koh at 13%, and Nguyen at 11%, with 47% of likely Democratic voters still undecided. Internal polls are typically released selectively to benefit the commissioning campaign, and no independent polling of the race has been published.

Nguyen was first elected to the state House in 2018 after defeating Republican incumbent Jim Lyons by 10 points. She chairs the House Committee on Climate Action and Sustainability. Before entering office, she worked as a staff attorney at Greater Boston Legal Services, representing survivors of domestic violence and sexual assault.
