I will support @Anonymous_ in that specifically stating a "reasonable salary" is not possible.
Just citing a case when you have absolutely no idea of the facts of the poster's business does not support a blanket statement. The decision in each case is decided based on the facts of that specific case.
The IRS does not have any specific guidelines on what constitutes a reasonable salary; no statute, no regulations, no revenue ruling, no revenue procedure, nothing. This is a very facts and circumstances determination. This will vary by agent, supervisor, negotiation, appeals, court.
A single owner S corporation that generates $1 mil in net income and only pays out $50,000 in wages would be hard pressed to prevail in court. Once again, each case is facts specific.
You should sit down with a tax professional and they would be able to review your facts and provide you with general guidance on what "might" be reasonable. Nothing is a guarantee and this is a highly scrutinized area for the IRS.
*A reminder that posts in a forum such as this do not constitute tax advice.
Also keep in mind the date of replies, as tax law changes.
