Mitt and Ann Romney have requested an extension for filing their 2011 federal tax returns, the Romney campaign announced late Friday.

The campaign released a copy of the extension request and an accompanying statement noting that “earlier this year, Gov. Romney released his 2010 tax return and an estimate of his 2011 income and taxes.” The statement, from spokeswoman Andrea Saul concluded: “This is an extension for filing his 2011 actual return, similar to what he has done in prior years.”

About 10 million of the 140 million annual tax filers request such an extension, according to IRS data. Romney announced the extension on the same day that President Obama released his tax returns.
