To file past-year taxes, gather documents (W-2s, 1099s) for that specific year, obtain missing info from the IRS using Form 4506-T if needed, use prior-year tax software or forms from IRS.gov (or USA.gov and TaxSlayer), and mail the completed paper return, as e-filing is limited unless you have an IP PIN. Be sure to use the correct year's forms and mail to the specific IRS address for your state.
