Uber tracks his mileage., and possibly his income, Generally I have not found it to be very profitable other than for personal pleasure. I have even had clients who purchase a separte care to use just for Uber or Lyft.
I will file my own BOI and no more. I will give them a letter so that they are aware of the requirements supported by several pages with more detail.
I am not going to answer questions or offer advice. If they have questions or need advice I will refer them to seek out a knowledgeable attorney.
FINCEN BOI has nothing to do with accounting, tax law or tax returns.
It is not administered by the IRS and our privileges and responsibilities under Circular 230 do not apply.
