How far back can i amend my tax return? I have recently received my daughter's SSN and would like to refile.

You can file an amended return for any tax year if the original return was accepted by the IRS and/or state.

You cannot amend a tax return for 2015 or a prior year to claim Earned Income Credit, Child Tax Credit or American Opportunity Credit if you or the dependent did not have their current SSN or ITIN prior to the due date for that tax year.  See this IRS website for information - https://www.irs.gov/uac/rda-2016-01-17-2015-p17

However, to file a return for a tax refund then you have up to three years from the original due date of return.  For tax year 2013 you must file the amended return for a tax refund on or before April 15, 2017.  All prior tax years after 2013 have expired for tax refunds.
