The IRIS Taxpayer Portal lets you upload 1099s as CSV files, but only in its own templates: one per form type, with fixed columns for the recipient's TIN, name parts, address and each box amount. Filling them by hand from a spreadsheet or another program is slow, and a wrong column means a rejected file.
If your 1099 software exports a Publication 1220 file, every value the template needs is already in it. Refile reads that file and fills the IRIS CSV templates for you: names split into their columns, amounts in the right boxes, large batches split into several files at the portal's limit.
It runs in your browser, so the TINs in your file never leave your computer.
Filled IRIS CSV templates from your FIRE file, for the 2026 tax year.
Opens in December 2026. Pressing Buy charges nothing now: it puts you on the list for launch.
