SEP IRA 20% or 25%

[JeffO]

I was told by my accountant that the maximum contribution I could make as a professional poker player was 20%, because I am considered the employer. However if I were the employee, then I could make a SEP IRA of up to 25%. Can anyone shed some light on this for me. I was always under the impression that I could contribute 25% into a SEP.

Thanks.
