My rule: Keep records and tax returns for years that include atypical transactions (sales or donations of property) and irregular income (stock option exercises, trust income, etc.) for six years after the filing date of the return. Keep a 2005 tax return that includes reporting of irregular items until April 2012.
(You only need to keep your most recent one; with one exception: keep the last one for the year until you get your W-2) Tax returns -- technically the rule is 7 years, but realistically you should keep them forever -- at least proof that you filed and what you filed (that is, the form itself).
