When do I need to file my PA amendment?

If you need to make any adjustments to your Pennsylvania state return or if the changes in your federal return affected your state return, you may need to file an amended return. You have 3 years from the original due date to file an amended California income tax return when requesting a refund, or within two 2 years since the tax was paid, whichever date is later.

If you reported too little income or too many deductions, or tax credits weren't claimed properly, then you have up to 30 days from the date you originally filed to file an amended. After 30 days, you will still be able to file an amendment, but you may owe late filing/payment penalties.
