How FillWise handles Form 1040
FillWise fills this form the regular way: the AI reads each field's printed caption, its tooltip and its options, and answers from your notes.
It also carries Adobe XFA data; FillWise fills the regular fields and drops the XFA part, so the result opens in any reader.
What to check before you file
- The edition. Agencies replace their forms with new editions. This page describes the 2025 edition; check that your copy is still the current one on irs.gov/forms-pubs/about-form-1040.
- Lines that bring in an amount from a schedule (Schedules 1, 2, 3 and 8812) must match the schedule you attach, and only one filing status box is ticked.
- Names and numbers character by character; signatures, fees and supporting documents stay with you.
