Issues about collecting sale tax before threshold reached by eCommerce

[airohugh]

Hi, experts

I'm operating a new LLC based on Wyoming. Our company operate a website which sell wooden dog sculpture to the entire united state. All of purchase including sale tax are collected by PayPal and stripe payment gateway.

I just learned that there is no consumption tax at the beginning of eCommerce business before the THRESHOLD reached of each state. (example: Virginia requiring tax collection and remittance when 

200 transactions threshold is reached)

Here is my question: 

1. Could I refund the sale tax collected to all paid customers to avoid early registration and remit sale tax to corresponding states? As these collected tax are incorrectly charged.

2. if my first assumption is wrong, please help me to advise a solution (affordable cost) to sort this issue out.

Sincerely appreciate help of my small business.
