You can set the tax rate when you are creating a new project, but you can always go back and change it if needed.
To change the tax rate on a project:
1. Open your project and click Project Details.
Change the tax rate under the Sales Tax field or use the Lookup Tax tool that pulls in the tax rate based on the project's address. Then click Update to save your changes.
