This may happen soon as suggested by Government Accountability office (GAO).
GAO noted that federal law currently prohibits the IRS from divulging taxpayer information, including unpaid federal taxes, to the State Department, unless the taxpayer consents. In contrast, federal law permits certain restrictions on the issuance of passports to individuals, such as individuals owing child support debts over $2,500 or with outstanding felony warrants.
The 224,000 tax delinquents who received the passports represented about 1 percent of the 16 million individuals who received passports in 2008. However, the estimated amount of unpaid federal taxes is probably understated because it excludes individuals who have not filed tax returns or underreported income.
