When businesses encounter duplicate tax invoices and credit card sales slips for the exact same transaction, a strict hierarchy for value-added tax deductions is required. According to guidelines enforced via the Hometax system, taxpayers must claim input tax deductions based on the tax invoice while treating the credit card slip as supplementary verification.
How Hometax Prevents Duplicate VAT Deductions
Taxpayers cannot claim input tax deductions twice for a single transaction settled with a credit card and accompanied by a tax invoice. According to the filing framework, businesses must reflect these transactions under the tax invoice receipt section of their value-added tax return. The credit card sales slip receipt schedule must only contain eligible amounts. Because Hometax inquiry amounts are totals of issued amounts, they may include non-deductible items that must be filtered to prevent over-deduction.
Managing Cancelled Transactions and Corporate Cards
Real-world tax accounting requires cross-checking of payment approvals and cancellations. According to practical tax filing rules, any transaction cancelled after initial payment approval is excluded from input tax deductions. Even when sole proprietors register business credit cards to record total amounts, operators must separately verify whether duplicate deductions exist. Deductible credit card claims demand that the value-added tax amount is separately distinguished, the expense is related to the business, and the transaction is not with a business operator or industry sector that cannot receive deductions.
Compliance Summary for Mixed Documentation
| Transaction Type | Primary Deductible Document | Secondary Document Status |
|---|---|---|
| Invoice and Credit Card Issued Together | Tax Invoice (세금계산서) | Credit Card Slip (신용카드매출전표) kept for evidence; excluded from the credit card receipt schedule. |
| Cancelled Payment Approvals | None | Excluded from input tax deduction eligibility. |
Ultimately, filing returns on Hometax means prioritizing tax invoice receipts for deductions and omitting those same transactions from credit card receipt schedules. Taxpayers are encouraged to separately check the latest revisions before submitting returns.
