From what I've observed (worked at a few small businesses before I got an office IT job, and even then...) it's about figuring out enough 'fringe benefits' and/or 'explanations' that are plausible with your CPA. e.x. how many profitable company car buy/leases can you do, a good explanation of why you are saving that money as a small or privately owned company (i.e. saving for expansion via acquisition/etc, but you have to follow through and then sell the results ASAP)

You can't have it be 'insignificant' salary but you can do plenty of fringe benefits or long term profiteering via acquisition as mentioned.

I will say, ironically, the small business owners like that were great to work for, although they were paranoid, they were often generous to employees.

OTOH, at the computer shop there was a standing rule that if the CPA brought his computer in it was 100% priority and we treated him better than the one org that was 10-30% (depending on year) of our entire gross income...

EDIT: To be clear, it's complicated, https://news.ycombinator.com/item?id=42199534 is a good explanation of where I sit overall.
