Yes! You can use AI to fill out Form 540 2EZ, California Resident Tax Return

Form 540 2EZ has a Form Complexity Index of 60 out of 100, placing it in the moderate complexity tier. This score is calculated deterministically from the form’s own structure using Instafill’s published Form Complexity Index methodology, so it can be reproduced and independently verified — it is not a subjective estimate.

For Form 540 2EZ specifically, the score reflects 135 fillable fields across 5 pages, grouped into 28 sections. The number of fields is the largest factor in the base score (weighted 36%), followed by how difficult those fields are to complete based on their type, where free-text and signature fields count for more than simple checkboxes (26%). The number of pages that actually contain fields (15%), the amount of conditional “fill-only-if” logic (16%), and how many sections the form is divided into (7%) account for the rest of the base. On top of that base, the index adds points for tables and repeating lists, bundled instruction pages, and dense page layouts — capturing difficulty the base alone can miss.

In practical terms, a moderate score means the form takes real effort: there are enough fields, pages and rules that errors are easy to make by hand. Instafill removes that effort entirely: our AI reads your information, maps each value to the correct field — including the conditional ones — and completes Form 540 2EZ accurately in under a minute, with every field available for you to review before you download.
