How long should I keep records for the Franchise Tax Board (FTB)?

FTB may request information regarding your California income tax return within the California statute of limitations period, which is usually the later of four years from the due date of the return or the date the return is filed. (Exception: an extended statute of limitations period may apply for California or federal tax returns that are related to or subject to a federal audit.)

Keep a copy of your tax return and the records that verify the income, deductions, adjustments, or credits reported on your return. Some records should be kept longer. For example, keep property records as long as they are needed to figure the basis of the property. In transactions relating to Abusive Tax Avoidance Transactions: 
  • For notices issued prior to August 1, 2011: FTB has 8 years after a taxpayer files a return to mail a proposed deficiency assessment. Therefore, tax documentation should be kept for at least 8 years. 
  • For notices issued beginning August 1, 2011: FTB has 12 years after a taxpayer files a return to mail a proposed deficiency assessment. Therefore, tax documentation should be kept for at least 12 years.
