The Department of Commerce has stated that those who receive a survey form are legally obligated to answer all the questions as accurately as possible. Those who decline to complete the survey may receive follow-up phone calls and/or visits to their homes from Census Bureau personnel. Section 221 of Title 13 U.S.C., makes it a misdemeanor to refuse or willfully neglect to complete the questionnaire or answer questions posed by census takers and imposes a fine of not more than $100. This fine was changed by the Sentencing Reform Act of 1984 from $100 to not more than $5,000. The Census Bureau prefers to gain cooperation by convincing respondents of the importance of participation. To date, no person has ever been charged with a crime for refusing to answer the ACS. The Department of Commerce states that it is "not an enforcement agency"

Short answer: don't return it, and if you get a follow up call say you never received it. At that point they may or may not ask follow-up questions. You can be fined if you decline to respond to those questions.

By who? The census department may have bullets but they have no enforcement division and if I remember right the census can’t give your personal info to the justus department because they are bound by some law not to.
