CLIENT TOLD ME HE HAD $500.00 DEDUCTED WEEKLY FROM NET PAY FOR MEDICAL 

INSURANCE.  HE PAID $25,000 LAST YEAR.  HE SAID H & R BLOCK TOLD HIM IT WAS PRE TAXED AND THEREFORE  NOT DEDUCTIBLE.  IT SHOWS ON HIS PAYCHECK STUB AS AN ADJUSTMENT TO NET INCOME.  HOW CAN IT BE PRE-TAXED IF IT IS DEDUCTED FROM NET INCOME.   I;M CONFUSED?

I PLAN ON DEDUCTING IT AS A MEDICAL EXPENSE?
