Can I catch up on past incorrect depreciation without submitting amended returns?

[caryn]

I have submitted the wrong depreciation percentage for my room rental in the previous years (100% versus what it should be...15.50) Doh! Is there a way to catch up and take less depreciation from this point forward so I don't need to submit amended returns?

You have two choices:

1. File an amended tax return as you stated, or
2. Complete and file a form 3115 to correct your depreciation error.

The easier of the two would be to amend your tax return(s).
