Am I to believe that no one here is a CPA or has never asked their CPA for detailed example??? I’ll bet 99% of MR is deducted, so dont ask, dont tell.
Lets please have a CPA give a few examples because Not one CPA in this state wants to answer that question!!! The CA FTB deflects question to IRS and the IRS gives generic answer with no examples. The FTB hints that generally answer is no, but REFUSES to provide examples, IRS refuses to provide examples, as do CPAs and tax lawyers. Maybe they want to bill $500/hr for 10 hours to answer no.
This question is not as complicated as those fancy FPGA thingamagics that SDR designs. If the IRS, FTB, cant provide reasonable guidance, then 99% are out of strict compliance.
