Keep the corporation’s records for as long as they may be needed for the administration of any provision of the Internal Revenue Code. Usually, records that support an item of income, deduction, or credit on the return must be kept for 3 years from the date the return is due or filed, whichever is later. Keep records that verify the corporation’s basis in property for as long as they are needed to figure the basis of the original or replacement property. QDDs should see the Qualified Intermediary Agreement for additional requirements.
The corporation should keep copies of all filed returns. They help in preparing future and amended returns and in the calculation of earnings and profits.
