# Relation of tax and slippage

if tax is low

setting slippage a little more than tax is sufficient

for example,

transaction will be done if set slippage to 10% when tax is 9%

and even if slippage is set much higher,

only tax amount is excluded from buy/sell amount

for example

even if slippage is set to 49% when tax is 9%

actual 9% of the buy/sell amount will be excluded for the sell

but if the tax is high,

slippage is much more needed than the tax value.

for example,

if 33% tax is needed, slippage should be set to 49%

you could see this relation easily in pancakeswap and poocoin
