How to Collect Sales Tax in Miamisburg

Ohio uses origin-based sales tax sourcing for intrastate sales and destination-based sales tax sourcing for interstate sales. This applies to Miamisburg as well. 

So, there are two types of sales tax collection depending on the origin of the sale:

• Intrastate sales: A sale is considered intrastate when the origin and the buyer's address originate from Ohio.
  
  If you make a sale originating in Ohio and the buyer’s ship-to address is also in Ohio, you should charge the sales tax rate of the sale originating point. 

So, let’s say your business is in Miamisburg, Ohio, and you sell to a buyer in Forest Park, Ohio. In that case, you should charge the buyer the sales tax rate at your Miamisburg location.

• Interstate sales: A sale is interstate if the item ships from outside Ohio and the seller isn’t “engaged in a business” in the state. Then, you should charge the sales tax rate at your buyer’s location. 

For instance, if your business is in Pittsburgh, Pennsylvania, and you sell to a buyer in Miamisburg, Ohio — you should charge the buyer the sales tax in Miamisburg.
