Ed Gillespie, an adviser to the Romney campaign, told "Fox News Sunday" that Mitt Romney would release his completed 2011 tax returns by Oct. 15.
In January, Romney released his 2010 returns, as well as an estimate for his 2011 returns, promising to release his completed 2011 returns when they were ready. The Obama campaign has pressured Romney to release more than two years of tax returns but Romney has repeatedly declined.
"Look, Oct. 15 is the deadline for the IRS on an extension. We have said as soon as they're ready we're going to release them. And I believe they'll be ready before that," Gillespie said, according to Reuters. "They're being finalized. There's a lot of forms that have to come in from other entities that the governor doesn't have control over."
Romney has estimated that his 2011 tax liability would be about $3.2 million.
