Itemized deductions not used in the year they are reported do not carry forward or back. Unfortunately, they pretty much become lost deductions.
Then what types of deductions can be carried forward on a personal return? I know I have read articles at one time or another about carrying deductions forward. Does that not apply to personal returns?
You are probably referring to Net Operating Losses (NOL) and Capital Losses. These looses are carried back if not elected to be carried forward on a personal return. Itemized Schedule A deductions do not affect these numbers.
