Fears that the I.R.S. could share their data with ICE have turned tax season into a gamble for people who are in the country illegally.
That they are undocumented immigrants did not deter them.
“Our thinking has been, if one day there’s immigration reform and the chance to legalize our status, we can show that we file our taxes, are not a burden — that we do the right thing,” said Mr. Quebedo, a car mechanic, who lives with his family in Los Angeles.
But as April 15 approached this year, the couple, who came to the United States from Central America, agonized over whether to file.
Their fears, shared by many of the millions of undocumented people who file tax returns, are rooted in the decision last year by the Internal Revenue Service to give immigration officials the addresses of people subject to deportation — a break with the tax agency’s longstanding practices.
