5. Token Tax
In addition to the platform fees above, creators can configure an optional Token Tax on their coin during creation. This tax is charged on every token transfer and trade and is distributed according to the creator's configured split across four channels: Funds Recipient, Holder Dividend, Token Burn, and Add to Liquidity.
Token Tax is completely separate from B.fun's 1% platform fee. For full details, see the Tax Token page.
