I am a psychologist who uses a billing service. How much of my payment to this service can I deduct as business expenses?

[rsd0123]

The billing service charges me 6% of what they collect for me.  This adds up to about ten thousand dollars.  Can I deduct 100% of this as a business expense?

All of it. Yes, it is a business expense. It is probably not as elegant but using a merchant services for credit cards can run about 1-2% and you would not need a billing service.
