The Sales and Use Tax Refund Application is a Kentucky Department of Revenue form used by taxpayers who paid sales or use tax and are requesting a refund of that amount. The form allows the applicant to provide business details, tax payment information, refund details, supporting explanations, and payment instructions so the Department of Revenue can review the refund request.
This application is used when a taxpayer believes they have paid sales or use tax incorrectly, paid more tax than required, or qualifies for a refund based on supporting documentation. The applicant must provide accurate information and include any required schedules, invoices, resale certificates, exemption certificates, or other relevant documents that support the refund claim.
The person submitting the application must be the individual or business that directly paid the tax to the Kentucky State Treasurer. Refund claims must be filed within four years from the date the tax was paid. Claims submitted after this period will not be considered.
Applicants must keep books and records supporting the refund request for four years from the date the refund is issued. These records may be reviewed or audited by the Department of Revenue.
