Selection of tax professional

Hello again,

what criteria do investors follow to ensure that a certified public accountant is qualified to manage your assets and deal with your taxation issues? (in conjunction with references from other investors and the degrees posted on the certified public accountant’s office wall)

For example: Would investors use as a criteria

1)number of audit cases (won against the IRS)
2)number of investment properties the C.P.A owns

Any other suggestions would be welcomed, thanks again for reviewing my post
