How to file your sales taxes in Iowa
Once your business has an Iowa sales tax license and begins to make sales, you are required to start collecting sales taxes on behalf of the Iowa government and filing regular sales tax returns. This page will help you understand the basics of your tax collection and filing responsibilities.
How To Collect Sales Tax In Iowa
Iowa practices a destination-based tax system. This means that the amount of sales tax that must be charged is determined by the buyers' location. You simply determine the tax rate of the area to which you are shipping, and then you charge that tax rate.
Sales Tax Collection Discounts In Iowa
While many states allow merchants to keep a small percentage of the sales tax they collect as a collection discount, or compensation for the work put in collecting the tax on behalf of the state, Iowa does not currently allow this.
