Corporate tax hike advocate Tim Walz had his China travel company shut down by the Nebraska government for failing to pay a minor business operating tax in 1998, according to corporate records. Educational Travel Adventures, Inc., which Walz founded with his wife in 1995 to run group trips to China, was dissolved by Nebraska’s secretary of state for "non-payment of occupational taxes"—just $26 annually—in April 1998. The company was left defunct for years, even as Walz continued to organize group tours to China.
