Prior Year Tax Returns

Filing a Prior Year Return

Only prior year 2010 tax returns can be e-filed. Other prior year returns cannot be electronically filed. Refer taxpayers to the Form 1040 Instructions for the appropriate address to mail their tax return. Also review the information about balance due returns in the Volunteer Resource Guide (Tab 12).

Tip

Taxpayers can also visit the local IRS Taxpayer Assistance Center to hand-deliver their prior year return or payment.
