When the appraisal district makes a change to an account, such as adding an exemption or adjusting the value, a monthly supplemental file is sent to the county tax office. Once received, we will update our records to reflect the change. If the change decreases the levy, an adjustment refund will be created for any overpayment made to the account. These types of refunds are generally processed 30-45 days from the date the tax office receives to adjustment from the appraisal district. Refunds of over $5.00 are automatically issued and no application is required.
