how the tax actually works
PUMPLOYER is a Token-2022 mint with a transfer-fee extension. The default fee is 5.00% of each transfer. The token program withholds that fee. A withdraw instruction moves the withheld tokens to the vault wallet. That is the tax. It is not a picture of a tax.
Pump.fun cannot host that fee on the narrative coins, so those coins launch as normal pump.fun tokens. Their creator-fee share is SOL. It is a different income line. The site does not pretend those coins charge 5.00%.
The agent never sells PUMPLOYER, including fees that arrive as tokens. The vault can hold both PUMPLOYER and SOL.
