If you've been trying to meet your state's sales tax requirements with the built-in solutions from Miva Merchant, you may be having trouble. Like most carts, only basic sales tax is supported. For Miva Merchant, this means calculating sales tax amounts based on a single sales tax rate per state. Many states have more than one tax rate, however - taxes may be defined by a county, a city, a shopping mall, a transit authority, and more.
Only AccurateTax.com's TaxTools products give Miva Merchant users the ability to accurately calculate sales tax on their e-commerce transactions no matter how complicated their states' laws.
We offer a Miva module for each of our sales tax products that installs and is used in place of your existing sales tax module. (For the Address Validation product, we offer a system extension module.) These modules call out to the AccurateTax.com servers at appropriate places during the customer's checkout process, to validate and scrub the shipping address, and to return any applicable sales tax rate(s), which are then used to calculate the amount of sales tax that the customer is charged.
