I had a business associate go through an audit. It was not specifically about net poker but the issue came up in the course of the review.

This person maintains detailed records of both online and B&M play, showing date, table played, buy-in & cash out and table time. He backs that up with withdrawal / deposit slips for a bank account that is used only for his poker bankroll - he makes withdrawals before each play and deposits the results right after. Any withdrawals to personal use he does using a cheque written to himself and deposits into his personal account.

The auditor spent an hour looking it all over, said "thanks" and there was no adjustment to taxes owing as a result of the audit.

Auditors for the most part won't have a deep understanding of the business / hobby of poker and if your documentation hangs together and is complete (i.e. looks like other business' supporting documents) then there is little they can say.
