Since I didn't get a definitive answer to my
post earlier about whether cash could be added to the gift bags to cover the taxes, I called a CPA and asked.
The answer is that corporations can, and indeed do, add cash to an amount paid to an individual to cover taxes on that amount. It is sometimes called "grossing it up", because it raises the gross amount paid to reach a certain net amount after taxes.
If you want to pay somebody in the 30% marginal tax bracket enough to cover the taxes on $100,000, you must add 100000x0.3 + 100000x0.3^2 + 100000x0.3^3 + ..., which is an infinite sum if not rounded off at each term. It converges to base_amount / ( 1/taxrate - 1 ), or in this case 100000 / ( 1/0.3 - 1 ) = 100000 / ( 3.3333 - 1 ) = 100000 / 2.3333 = $42,857.76, the same number I computed earlier.
So now we know. And I can sleep peacefully tonight.
