Missed Depreciation
Never claimed depreciation?
Estimate what a Form 3115 catch-up could recover in a single year — the deductions you were entitled to but never took. (You still owe recapture either way, so you may as well claim them.)

A Form 3115 §481(a) adjustment can pull this whole amount into a single year’s deduction.
Read this before you count the cash. This is a deduction, not a refund — its cash value depends on your bracket, and passive-loss rules can suspend it until you have passive income or sell. The fix is Form 3115, not an amended return, once you’ve missed two or more years. And recapture is owed on depreciation “allowed or allowable” when you sell — whether or not you ever claimed it, which is exactly why catching up is usually worth it.
