So far, through the legalese and gobbldy-gook that is the Texas government website arrangement, I've garnered that I have a few things to do to open up my dealership and smithy shop here in Seagoville. If anyone has a business in Texas, or otherwise has experience with these issues, could I trouble you to help me out with these issues? - the self employment tax; if there is such a thing, how much is it on average? I have never heard or such a thing, so I don't know if it's on a federal or state level. - the NAICS code; each business has one, but they are not individualistic, each type of business has one. My email to the state two days ago has gone without an answer, and I'm getting antsy. Apparently there is a code for a gunsmith without retail, and one with wholesale, but not one with retail. - Sale tax; Texas had no personal income tax, but I don't know about a business tax. We have to charge 8.25% of the value of each purchase as sales tax. How often is this tax paid to the state. Some sources say annually, some say quarterly. - do texas firearms dealers need an EIN even without the extra employees? Any light you can shed on this would be very helpful. So far the state surely hasn't been.
