Using IP(Internet Protocol address) to calculate Tax
<p>I understand that if I sell things online, I need to calculate Taxes based on customer location. </p>

<p>Can I use IP(Internet Protocol address) to locate customer or should I ask them explicitly?</p>

<p>If it is fine to use IP to identify customer's Country, is it fine to locate customer State/Province. </p>

<p>I need it because Canada has different taxes in different Provinces.</p>

<p>You ask them explicitly, maybe adding that you need that info specifically to calculate tax.</p>

<p>IP address is not reliable because your customers could be using VPN, Tor, or be on vacation overseas.</p>

<p>(By the way, "IP" on a website about law would more likely be understood as "Intellectual Property", not "Internet Protocol address".)</p>
