If you are purchasing materials and making crafts, the materials should also be purchased tax free from a wholesale supplier. If the weekend fair is the only time you will be selling crafts in Tempe, there is a one-time event tax license available. I participated in a weekend craft sale and only sold a few items. In fact I really didn't even make a profit after considering all of my expenses. Selling at a weekend craft sale is subject to the same tax and license obligations as a retail store.
All items sold at the craft sale are taxable.
I participated in a special event at Kiwanis park. If you obtained a one-time event license, you are required to report and remit payment of tax within 15 days of the end of the event. If you are a permanent Tempe license holder, you would report and pay tax on items sold at the event when you file your next tax report, either monthly or quarterly as required. Depending upon the number of rental properties you own, you may need a privilege tax license. However, if you own one rental property in Tempe, and then acquire another rental property somewhere else in the State of Arizona, effective the date that you acquired the second property, rental income on the Tempe property becomes taxable.
