Keep records for 3 years from the date you filed your original return or 2 years from the date you paid the tax, whichever is later, if you file a claim for credit or refund after you file your return. Keep records for 7 years if you file a claim for a loss from worthless securities or bad debt deduction.

Usually this is 4 to 7 years from the due date of the return, or the date filed, whichever is later. If you under-report your income on your return by 25% or more, the statute of limitations is 6 years from the due date of the return or the date filed, whichever is later.

In California, the general statute of limitations is three years for taxpayers who have filed tax returns. That means the CDTFA has three years within which they can audit those returns. However, if you fail to file tax returns, the statute of limitations is eight years.

The IRS has three years after the tax return due date or the date the return was filed to assess a tax against you. If you unreported your gross income by 25% or more, the IRS can assess taxes six years back. If you committed fraud/evasion or if you didn't file, the IRS can go back an unlimited amount of time.

By signing a waiver of statute of limitations, the CSED can then be extended by no more than five years. The IRS can only request that you sign the waiver if it is in conjunction with a filed installment agreement.
