減稅

减 = 冫 + 咸 : Joan of Arc (ji) found that there's a giant popsicle (冫) obstructing the way to the bar inside of the anthill (an3). To clear the way, she reduces (减) the size of the popsicle by scattering salt (咸) all over it.

税 = 兑 + 禾 : Sheldon Shrimp opened an exchange booth in the Eiffel Tower's bathroom, and shortly thereafter a tax collector visits to collect the tax. Sheldon's business was rather mediocre though, so he can only offer a bowl of cereals as payment.
