If I missed the dependent deduction for several years, can I file for multiple years of refunds at once?

Brief answer: Within the five-year correction period, each year requires a separate Correction Request form, with withholding slips and remittance proof prepared per year.
Detailed explanation
For example, if 2021–2024 were all missed and within the five-year window, file a separate Correction Request for each year with that year's withholding slip and living expenses remittance records. Multiple years cannot be combined into one tax year. Refunds are deposited separately by year to the designated account. This tool supports multi-year estimates and document generation. If a year lacks a withholding slip or remittance records, that year may not be recoverable. Expired years cannot be recovered. Confirm deadlines per year with the tax office or this tool.
