Hi Ruko, I`ve done a little research on this and I believe it works like this. If you buy from an online retailer you are not taxed unless you reside in the same state as the business you are buying from. Where I live for example the State of Washington will require online retailers to collect and pay sales tax for any sold items shipped to a customer within Washington State. If an item is sold and shipped to a customer out of state, no tax is collected on the sale. State tax laws vary but this is the case for WA. Currently there is a group of states working together to figure out how to capture all that lost sales tax revenue so this nice benefit to online shopping may not last for long.
Any business who is selling as interstate or a foreign commerce are liable for sales tax where the product is delivered, and therefore they collect the sales tax based on where you live for the city, county, and state and other special taxes. Texas has many taxes that a retailer is liable for. You will be charged the company that collects the sales tax that you paid will be filed to your state on whatever recurrence your state deems necessary. I have worked with a interstate and foreign commerce where we had sold items and delivered them to a texas resident and were liable for the taxes and the state keeps track of these things.
It's been a while since this thread has been updated . The rules have changed over the past couple years. Doing business online is like doing business in the wild west. Lots of great areas. Since the recession began many states have changed the rules on how e-commerece businesses are taxed. Your best bet --speak to your CPA.
Sales Tax can be very confusing.
Check out this blog to find out some information about what to look for when it comes to sales tax online. Its a very gray area still and there are many issues that are still being worked out with each states government.
Hope this helps!
