Most businesses think tax is based on where they are located. It is not. It is based on where they have nexus. Without understanding nexus, businesses either collect tax everywhere or miss obligations entirely. Both create unnecessary cost and risk.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Nexus is not location<\/h2>\n\n\n\n<p><strong>Most businesses assume:<br><\/strong>tax = where the business operates. That is incorrect<\/p>\n\n\n\n<p><strong>Tax is based on:<br><\/strong>where nexus exists. Nexus is your connection to a state that creates a tax obligation. Without nexus no tax is required<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why businesses misunderstand nexus<\/h2>\n\n\n\n<p>Nexus is misunderstood because it is not visible<\/p>\n\n\n\n<p><strong>It requires tracking:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Revenue by state<\/li>\n\n\n\n<li>Transaction counts<\/li>\n\n\n\n<li>Customer distribution<\/li>\n\n\n\n<li>Physical presence<\/li>\n<\/ul>\n\n\n\n<p>Most businesses do not track this properly.
