can amended tax returns be verified by irs
The IRS 1040x Amended Tax Return forms. Even taxpayers who filed by April 15 may not be done wrangling with Uncle Sam any time soon. The reason: They're amending their return. In most cases, the IRS gives taxpayers three years from the date they filed their original return, including extensions, to make changes. Regardless of what form you initially filed, and how, federal income tax amendments must be submitted via paper using form 1040X. Each state has its own forms and procedures.
