Internal Revenue Service regulations make it possible for the health insurance deductions to be taken from your pay prior to the calculation of your taxes. This reduces your taxable income for the year. This may mean you pay less in income taxes and have more take home pay. Your personal tax advisor may help you clarify the impact on your personal tax planning.
If you do not want your health deductions to be taken from your pay before tax, you must contact the Benefits Center at 1-866-325-2345 and request your deductions be taken "after tax".
