The setting to turn off taxes (for estimate reports, as shown below) also turns off taxes when exporting invoices to QuickBooks.
For QuickBooks Desktop users, here's how you will find this option:
- Open your LMN QuickBooks Sync Tool (the program you installed from your LMN account)
- On the LMN Estimating side of the program, find step 3; titled Choose your Import Settings
- From there, select My Company does not charge Sales Tax (Taxes OFF)
