1. I shouldn't have said no deadline. The IRS doesn't recognize tax returns going back more than 7 years - those are closed years. So I guess there is a seven year deadline from the date that you filed. Three years in order to get a refund that was owed.
2. States are all different. What state?
3. Yes, three years from the date that you filed. No specific month for federal purposes. I doubt it for state.
4. Yes. Each tax year is a separate account. So having amended returns for prior years has no bearing on other years' taxes.
