Features of the Inheritance Procedure Deadline Countdown Tool

By simply entering the date of the decedent's death, the tool displays a list of all deadlines and remaining days for inheritance-related procedures.

Input

• Date of death of the decedent (Start date of inheritance)

Output

• Deadline for Renunciation of Inheritance (within 3 months) — Displays remaining days and deadline date.
• Deadline for Quasi-Final Income Tax Return (within 4 months) — Displays remaining days and deadline date.
• Deadline for Inheritance Tax Filing and Payment (within 10 months) — Displays remaining days and deadline date.
• Deadline for Claim for Refund of Inherited Portion (within 1 year) — Displays remaining days and deadline date.
• Deadline for Request for Correction of Inheritance Tax (within 5 years and 10 months) — Displays remaining days and deadline date.
• Overview of each procedure and risks associated with missing deadlines.

Background of the Release

The deadline for filing and paying inheritance tax is set within 10 months from the day following the date the decedent's death became known (Inheritance Tax Act, Article 27). Missing this deadline may result in penalties such as delinquent tax or additional tax for failure to file.

According to National Tax Agency statistics, the inheritance tax taxation rate has reached a record high of 9.9% (Source: National Tax Agency, 2023 Inheritance Tax Filing Results). Since inheritance is an event most people experience only once or twice in their lives, managing multiple deadlines—such as 3 months for renunciation, 4 months for quasi-final returns, and 10 months for inheritance tax filing—is not easy.

This tool clarifies "what needs to be done now" by automatically calculating all deadlines based on the date of death.

Who this tool is for

• Those who have just experienced a death in the family and want to understand the overall picture of the procedures.
• Heirs who want to manage multiple deadlines without omissions.
• Those who want to check if the deadlines for renunciation of inheritance or quasi-final tax returns are approaching.

※ This service does not constitute tax consultation under the Certified Public Tax Accountant Act. Please consult a tax accountant or other professional for specific filing procedures.
