The pretax margin, as know as pretax profit margin, is widely used to measure the operating efficiency of a company before deducting taxes.
The pretax margin is sometimes preferred over the net margin as tax expenditures can make profitability comparisons between companies misleading.

The long term trend of the pretax margin is a good indicator of the competitiveness and health of the business.
