Medical practitioner pal runs an office. Maybe five employees. It's a corporation. Not sure if Subchapter S.

Same CPA cranking out taxes, salaries, financials for him for years.

Let's say his salary is $100k. I did not ask. Normally a 50% bonus is paid into deferred income. The CPA forgot to do this last year.

So the $50k deferred income remained in the corporation and income tax was paid on this. His window of stuffing the 50k in a deferred account has been lost. I suspect he received the net via however corp earnings are distributed to him as sole owner/share-holder.

Anyhoo, the CPA is really sorry. But my pal is out the earnings potential of the taxes paid because of the oversight.

Thoughts on how these situations are handled or can be handled?

Although an oversight, kinda seems some form of liability on the CPA's part could be argued.
