We would be happy to setup your e-commerce website to collect any taxes from any areas you tell us to. Unfortunately, as Creating Digital is not an accounting firm we cannot offer any tax advice or tell you which states, regions, counties, or cities you should be charging and collecting tax from and reporting to.
Tax is a very complicated subject as some states are a supplier based state and others are a delivery based state. The supplier state based model means you need to collect tax from the jurisdiction in which the warehouse is. In delivery based states you need to collect and report tax for the jurisdiction in where the product is being delivered to.
To further complex matters taxes are sometimes more complex as a state of NJ is pretty simply with its 7% state wide tax. However did you know NJ has Urban Redevelopment Zones in which the tax rate is 3.5%? Does this affect your business? Other states like NY have different tax rates by city. For example, Westchester has a different tax rate than Manhattan.
Tax is a very complex problem. For clients on our Magento ecommerce solutions with physical storefronts processing over $2 million USD a year we recommend looking into taxjar and avalara if you require extensive tax management needs. For all clients we recommend you chat with your accountant about your online tax collection needs. Once you and your accountant have figured out what you need to do to be compliant, please let us know the states and regions you will collect tax from and the rates and we will be happy to implement!
