for missed rental property depreciation.
Just a bit of a clarification: It isn't merely for "missed" depreciation; it is for missing depreciation due to an incorrect Accounting Method.
If you did not take depreciation in the first or second year of it being "placed in service", yes, you need Form 3115 to start claiming depreciation and to 'catch up' on the missed depreciation. If you originally started taking depreciation in the first and/or second year, but then later stopped claiming depreciation, that can only be corrected by amending.
