A Cash Receipt Was Self-Issued — Now What?
How to register a self-issued cash receipt (010-000-1234) on Hometax, with steps for both individual and business taxpayers and key merchant considerations.

After a Self-Issue
A cash receipt issued to the self-issue number (010-000-1234) is stored in the National Tax Service (NTS) system in a temporary, unattributed state. For the customer who actually made the payment to claim the associated tax benefit, a follow-up step — registering their identity — is required.
Why Is Follow-Up Required?
A self-issue is an anonymous receipt — it's issued without any customer identity information. The NTS Hometax system requires an explicit step to link [receipt data + customer identity] before the receipt can count toward year-end income deduction or business expense documentation.
Registration Steps by Taxpayer Type
The menu path and process differ depending on who the customer is. Here's a quick reference:
| Type | Taxpayer | Identifier | Hometax Path |
|---|---|---|---|
| Income Deduction | Individual (wage earner) | Mobile number or card number | Inquiry/Issue > Cash Receipt > Register Self-Issued Receipt (Consumer) |
| Business Expense | Individual or corporate business | Business registration number | Inquiry/Issue > Cash Receipt > Register Self-Issued Receipt (Business) |
3 Things Customers Need to Register
The merchant must provide the following information so the customer can complete registration:
| Field | Description |
|---|---|
| Approval Number | The 9-digit number returned in the issuance response |
| Transaction Date | The date the receipt was issued |
| Amount | The final payment amount including VAT and service charge |
Timing Note
For Business Customers: A Better Path Than Hometax Registration
Hometax does have a "Register Self-Issued Receipt (Business)" menu, but for corporate accounting teams, the cleaner approach is to contact the merchant, cancel the original transaction, and request a reissue using the business registration number.
Why this is recommended:
- Retroactive registration carries a risk of missing the input VAT credit in your accounting system.
- Reissued receipts sync automatically with ERP systems, whereas Hometax-registered self-issued receipts may not.
How to request it: Call the merchant's customer support with the approval number, transaction date, and amount, and ask for a "reissue to business registration number."
Common Questions
- Cancel + reissue vs. direct Hometax registration: If a customer later asks for a receipt under their own number and a self-issued receipt already exists, directing them to register it directly on Hometax is administratively cleaner. They receive the same tax benefit, and you avoid the risk of double issuance or omission that can come with cancel + reissue.
- Digit count check: The self-issue number must be exactly 010-000-1234 (10 digits). Only the correct format allows the customer to match and register the receipt on Hometax.
If the self-issue workflow is still unclear, the cash receipt documentation covers the full end-to-end flow.
