Are taxes added automatically when quoting or closing a sale?

Yes, national taxes are automatically calculated and included. Just forget about them. This feature is unique to FL3XX, so much so that we made it available on the EBAA website at http://www.ebaa.org/en/current-issues/taxes.aspx and on paxtax.eu where those who don’t use FL3XX can save hours of tedious work, figuring out the complex tax rules of UK, France, Italy and many other countries that apply taxes.
