A suggestion from the Wall Street Journal:

Even after the IRS audited him in 2006, Mr. Geithner paid back taxes only for the two years -- 2003 and 2004 -- for which he had been audited. He did not bother to amend his 2001 and 2002 returns until late last year, when the tax issue came up during the Obama vetting process.But [Senator] Baucus, who once called the tax gap "an affront to all the rest of us who pay our taxes," is not affronted. "This is an honest mistake and it's clear there was no intention not to pay," said the Finance Committee Chairman.For our part, we are delighted that Mr. Baucus and Democrats are suddenly in such a forgiving tax mood. In addition to being a teaching moment for liberals, perhaps Mr. Geithner's tax snafu can do all of America some good. We'd suggest that Mr. Geithner and Mr. Baucus together set a new standard for the IRS in dealing with people who, like Mr. Geithner, make a boo-boo on their tax returns.Let's have an amnesty -- with penalties waived, as they were for Mr. Geithner -- for all those Americans who somehow "forgot" to pay their taxes but are now willing to fess up or are audited. If forgiveness is to be the order of the day for the man who may soon be responsible for the IRS, American taxpayers deserve a similar reprieve.
