Sales Tax Compliance

Before you can begin collecting sales tax in other states, you must complete an e-commerce business registration in that state as well as possibly apply for and obtain other permits, depending on the laws in that state. We can complete your sales tax registration in the various states in which you have nexus.

Once your company is registered, however, taking the steps to ensure your business achieves sales tax compliance can be intimidating. It’s not so difficult when you operate a brick-and-mortar store at which you simply charge the local rate. But when you operate an e-commerce store, the rules change. That’s because e-commerce vendors often sell their products to customers in states other than the one their business is located in — states that sometimes have different tax rates. Additionally, the city or township your customer lives in may levy additional taxes. Paying taxes to these states and jurisdictions is what is meant by the term “use tax.” Charging and paying e-commerce use taxes and sales taxes are simply part of doing business online.
