This question is for people who have an e-commerce company that have sales in other states. How do you keep track of the taxes?? What resources have you found that have helped you with dealing with the sales and use tax of each state? I've bought numerous stuff online and haven't been charged tax before and I'm not sure if it's because the company is not being compliant or if it's because I live in Texas. I've read some stuff on Nexus, but still confused. So if you have a website with some great information that you've used that would be very helpful!! Also, did you file for a sale and use tax ID for each state??
