We are working with an S-Corp client that is a Wealth Management/Financial Advisors business.  I know this is considered an SSTB for QBI purposes but I've heard certain revenue sources may still qualify for the QBI deduction but I've been having trouble finding anything to back this up.  

The company's revenue streams include annuity sales, insurance commissions and revenue from assets under management.  

Would any of these qualify for the QBI deduction and be excluded from being considered SSTB income?

Thanks in advance for your help.
