Start by opening the CONFIGURATION MENU by pressing on the configuration button in the top right.

Then select COMPANY SETTINGS to open your company configurations. 

Once in the edit menu, you can access the sales tax menu by clicking the Sales tax button at the top right.

A new window will open in which you can modify your sales tax rate and the frequency of reporting your tax reports to your government.

By default, the tax rate for Sales tax is automatically set to comply with the tax regulations of the country of your company. We do not advise you to change them. However, you should change your filing frequency to match that of your company.

If your country was not included in the drop-down choice of countries and you chose "Other" as your country, you should manually set up your tax rate for Sales Tax. By default, the tool uses global averages that may not be suitable for your country's tax regulations.
