Answer:

How long should I keep my tax papers?

At least three years, but six years is preferable. The IRS has three years after you file a tax ­return to complete an audit. The IRS can audit you for up to six years if it suspects that you underreported your income by 25% or more. If the IRS suspects fraud, there is no time limit for an audit, although audits beyond six years are extremely rare.
