A request for payment for a charge by a provider to a customer having a plurality of accounts is received at a host computer. At least one of the accounts qualifies for pre-tax treatment and at least one account does not qualify for pre-tax treatment.

If the charge qualifies for pre-tax treatment, then at least the account qualifying for pre-tax treatment is debited for some or all of the charge.
