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.
However, the six years is from the end of the period for which the tax return was filed, so for a tax return filed in 2015 you must keep the records until December 31 of 2021 (one day less than seven years). Most businesses keep their records for seven years to avoid confusion.
