Brief answer: A Correction Request form is the official form to request correction of past income tax filings and a refund from the tax office. Supplemental claims for overseas parent deductions usually require printing and mailing to your local tax office.
Detailed explanation
The form states the reason for correction (adding dependent deduction), original and corrected tax amounts, and refund amount. Supporting non-resident parents overseas is difficult to prove fully through e-Tax online, so the common practice is mailing paper tax forms, Correction Request form, withholding slip, relationship proof, and remittance evidence. Use the form for the relevant tax year. Include your address, My Number (can be added later), and refund bank account. Mail by registered post and keep shipping records. After acceptance, the tax office may send inquiries or request additional materials. Final decisions rest with the tax office.
