I do not have a Tax ID/ Resellers ID, I sell on ebay, Do I charged taxes?if yes to whom?

Answer 1

You can't charge any tax (unless you have a sales tax permit). If it's a business, then you may be required to register with your city/county sales tax office. Check of the State web site.
Then when you sell to someone in your state, then you have to collect sales tax and remit it to state’s sales tax office.

When you have sales tax permit, then you can normally buy goods without paying sales tax. Then, when you sell the goods, you collect the sales tax.

Answer 2

You cannot charge someone tax if you do not have a tax id.

If you buy things with the intention to sell things then you should get a resellers id and a tax id. That's all standard irs stuff and you seem interested in that because you are asking. Once you have those things you can only charge tax to people that live in the state you pay taxes to.

If you only sell your own belongings then you do not need either.

Answer 3

If you are selling regularly on ebay, and selling items that are taxable in your state, you need to get a tax ID from your state, and charge sales tax to anyone from your state who buys taxable items from you.
