Yeah, it’s California.

I bought a plane from a guy who lived in California - I flew commercial to meet him in Vegas, then I flew the plane all the way back home to nearly the Atlantic ocean.

Of course California threatened to sue me because I wasn’t paying them taxes on the aircraft, even though I don’t live there and I’ve never flown the plane there. Ended up getting it fixed, but from what I can tell California will go after any revenue they think they have even a tangential claim to, and if they think you can be intimidated, tricked, or otherwise forced to pay then they have no problem doing so.

My policy has been “it’s full price or it’s free.”

Don’t discount. Give it to them and invoice it as full price, marked down with a 100% family rdiscount. Or charge full price.

They’ll value a $400 art piece they got for free much more than the same piece that they argued you down to $40 on.

Well, if you were compensating per-mile driven for mileage, and he drove more than you, would that be unfair?

What about travel, and his job responsibilities require more travel?

It’s a business expense. Don’t compare it, just cover it.
