Environment

Resolution

There are several reasons why the tax amount may be incorrect.

• The tax rate in the jurisdiction may have changed.

• The address on the invoice has only a State and Zip Code.  

  • Always include the address, city, state and zip code on a transaction. This ensures the precise tax rate is generated. 

• You may not have established Nexus in the taxing jurisdiction

• If you have Nexus in the jurisdiction you may not have the correct tax type selected.

  • If that is the case then we suggest contacting the applicable state to verify which tax type you should be collecting.

• If there is a Tax Code in the transaction it may/may not be taxable in the applicable jurisdiction

• If there is an Entity Use Code being used it may/may not be taxable in the applicable jurisdiction

• If there is an Exemption Certificate being used it may/may not be taxable in the applicable jurisdiction

• If you are using a Custom Tax Rule it may not have been applied correctly.

• There may be a Jurisdiction Override in place for the specific address and/or zip code. Alternatively, it could be that a Jurisdiction Override needs to be created to compensate for a boundry that has just changed.
