Generally, just like all financial transaction and reports, you should keep your corporate tax returns for a period of at least three years.
This is the allowable period when you can amend tax returns.

Any record of items claimed for depreciation should be kept as long as the item is still depreciating. For instance, if a corporation claims depreciation of assets on a certain period, any records relating to the purchase of the assets should be kept within that timetable.
