A rendition refers to a form that you need to submit to the district. You have to put the description, location, cost, and acquisition dates for your personal property. The district uses this information to estimate the market value of your property for taxation purposes. You need to get this form, fill it up correctly, and submit it before the deadline. The last day to file your rendition is April 15 annually. Suppose you want to mail your rendition; it must be postmarked by the U.S. Postal Service on or before April 15 and must be filed at the appraisal district office in the county in which the business is located.
