The 501(c)(4) organization, U.S. Term Limits, now has some more trouble. The Democratic Senatorial Campaign Committee (DSCC) has filed a complaint with the Internal Revenue Service (IRS) claiming that the group violated the law by not disclosing on its Web site that contributions made to the group are not tax-deductible. Roll Call ($$) reports that the "complaint against U.S. Term Limits comes as the Internal Revenue Service is stepping up its enforcement of nonprofit organizations that engage in political activity, particularly 527s and 'social welfare' groups that register under section 501(c)(4) of the tax code. The DSCC's complaint to the IRS is the first time that the committee has sought to strip an outside political group of its tax-free status." Meanwhile, the Democratic Congressional Campaign Committee (DCCC) filed a second complaint with the Federal Election Commission (FEC) against the organization Freedom's Watch. The DCCC complaint alleges that Freedom's Watch ran a television "attack ad that directly and illegally advocates the defeat of a Democratic candidate and also for failing to disclose the names of the donors funding that ad."
