Field notes
The workflow accepts a prior-year input PDF made with Nenchō-san or its saved data, then separates information that can carry over from details users should revisit. The listed carry-over fields include names, addresses, family names and birth dates, and insurance contract information. Users are prompted to check current income, premiums, and household changes, while the page says age- and income-based deduction determinations are recalculated. The listed forms span Reiwa 8 and Reiwa 9 tax years.
