Real Voice

That concern of yoursis really a "worry consultation."

Does this count as an expense? I'm thinking of buying a car… I'm thinking of hiring someone… How much should director's pay be? Should I set up a company?

These kinds of questions —no matter how small.

Not a "tax consultation"
but a "worry consultation" — start there.
