For Harris County Appraisal District, most businesses will need to file the general rendition form, 22.15. List of properties (real and business personal) you currently own in Harris County (if applicable).Q. Can I bid on behalf of another party? This type of business personal property is meant to be taxable at the very same tax rate as any real property in Texas. Business Personal Property tax is an ad valorem tax on the tangible personal property that is used for the production of income. Business owners are required to report the value of their personal property each year. This value is used to calculate the amount of tax owed. How do I fill this out? I am paying tax for my businesses assets that I have already paid tax on when I bought them. Is it difficult to file a BPP rendition?
