Graduate students and their supporters walked out of their classrooms and research labs at campuses in Southern California and across the nation Wednesday to protest a GOP plan that would classify their tuition waivers as taxable income.

Organized by graduate students at USC, thousands attended simultaneous rallies and a “Grad Tax Walk Out” on at least 60 campuses across 33 states. Students at all of the UC schools participated, organizers said, including UC Riverside, which held a “Grad Teach-In” featuring student speeches.

The students said most of them live on small stipends and would be financially crushed if a GOP tax plan, passed by the U.S. House of Representatives this month, becomes law.

“We would be paying taxes on money we don’t receive,” said USC grad student and organizer Nina Jhaveri, 33, a Newport Beach resident who said the tax increase would have a devastating impact on graduate students, leading many to drop out of school.

The House tax plan includes provisions that could impact higher education and families with children in college, including one that would eliminate a student-loan interest deduction allowing borrowers to deduct up to $2,500 annually. But on Wednesday, the attention was focused on a provision in the GOP tax plan that could increase graduate students’ taxes by as much as 400 percent.

“It would be crippling,” said Ben Leffel, 30, a UC Irvine Ph.D sociology student and teaching assistant. “The tax would force me to make a decision between rent and food. I’m already close enough to making those decisions now.”

Graduate students typically are paid stipends and granted free tuition in exchange for teaching classes and doing research. Under the new plan, the value of their tuition would be taxable. Now it is not.

House Republicans voted for the changes on Nov. 16 as part of a $1.5 trillion package meant to overhaul the U.S. tax code and enact President Trump’s economic agenda.

They said they want to simplify the tax code, provide tax cuts and repeal portions of the Affordable Care Act. Both the House and the Senate measures would nearly double deductions to approximately $12,000 for individuals and about $24,000 for married couples.

Tuition varies even within the UC system; at UCLA, tuition and student fees for most doctoral and master’s programs are about $16,800 for California residents and about $32,000 for non-California residents.

“We live on extremely small stipends, between $18,000 and $22,000 a year,” said UCI graduate student Mary Schmitt, 38, a teaching assistant in the visual studies program.

Kurt Horner, a fifth-year UCI economics graduate student and a leader with the UAW 2865 union that helped organize the UCI walk-out, said the tax plan could cost him and most students in the public school at least $2,000 more annually in taxes. He makes $18,000 during the school year.

For out-of-state students and those in private school, the numbers are much higher.

At USC, Jhaveri receives a waiver on her tuition of nearly $44,000 a year and she’s paid a $29,500 stipend for her clinical psychology work.

“If you take $30,000 home and you’re paying taxes on close to $80,000, that’s not something you can live on,” she said.

Schmitt, of UCI, said: “In many ways, this is an attack on graduate education in general, because it’s going to become that much more unaffordable.”

Universities and educational organizations, including the American Association of State Colleges and Universities, have opposed the Republican tax reform package. UC said it threatens the nine-campus system’s ability “to carry out its research, education, health care, and public-service missions.”

“Ninety-six percent of our Ph.D students receive tuition waivers,” UCI Vice Provost and Dean Frances Leslie wrote in an e-mail to the Southern California News Group. “Since many of them are low income, this will mean that they may have to drop out. That will be a tremendous loss of talent to the state of California.”

As part of Wednesday’s protest, students and their supporters took to social media with the hashtags #gradtaxwalkout and #savegraded.

THE #GOPTaxScam could increase taxes for grad students by 400% while giving giant corporations a tax break. That is not acceptable. Thank you @uaw2865 at UCI for organizing the #GradTaxWalkout pic.twitter.com/DD4Xyg7LFA — Katie Porter (@katieporteroc) November 29, 2017

Some grad students said they were unclear on whether the proposed plan would also affect their fellowships, grants and scholarships. Max Chao, a full-time lecturer who specializes in tax law at the UCI Paul Merage School of Business, said there’s some uncertainty.

“It seems related to any grant or fellowship but I can’t say for certain,” Chao said. “It’s so vague.”

But tuition waivers for undergraduate students, including those in community colleges, are unlikely to be affected because undergrads do not receive them in exchange for work performed, Chao said.

Other deductions and credits for college students that could be affected:
