Who Needs a Sales Tax Permit in Big Lake?

A sales tax permit or seller's permit is typically issued by states in the United States. You can apply for one in Texas at the Texas Comptroller website. A seller's permit allows you to collect and remit sales tax on your products.

You need one if you:

• Sell tangible personal property in Big Lake or anywhere in Texas
• Lease or rent tangible personal property in Texas
• Sell taxable services in Texas
• Sell or lease tangible personal property or taxable services to customers in Texas from an out-of-state business and have revenue from Texas of $500,000 or more in the past 12 months

Note: If consumers purchase goods from outside the state but use them within the state, you can collect use tax if they haven’t already paid sales tax. 

How to Collect Sales Tax in Big Lake

Since Texas uses origin-based sales tax sourcing for intrastate sales and destination-based sales tax sourcing for interstate sales, the same applies to Big Lake as well. 

According to Texas sales tax law, here’s how to collect:

• Intrastate Texas sales: A sale is considered intrastate if it ships from an origin in Texas to a buyer's address in Texas. For example, if your business is in Big Lake, Texas and you make a sale to a buyer in Paducah, Texas, you need to charge the buyer the sales tax rate at your Big Lake location.

• Interstate Texas sales: A sale is considered interstate if the item ships from outside Texas and the seller isn’t otherwise “engaged in a business” in the state. In such cases, you’d generally charge the sales tax rate at your buyer’s location. For instance, if your business is located in Leander, Idaho, and you sell to a buyer in Big Lake, Texas, you should charge the buyer the Big Lake sales tax rate.
