The "wife tax" is referring to the guilty present that a husband has to buy for his wife when he mad a purchase of something expensive for himself.
For example if the husband got himself a Ferrari, he might need to buy his wife a diamond necklace as a "wife tax".

Its a funny way to say that your wife gets a cut of any unexpected financial gain. Like if you hit a lottery or win a big bet the wife gets her share.
Yeah bro I was in Vegas and won $500 playing craps but after the Wife Tax of 40% I only got to keep $300.

Taken from your net pay, often straight from your wallet, the Wife Tax is a mandatory contribution directly to your spouse's spending money.
I was going to buy those parts to fix the family car and renovate the bathroom, but I got hit pretty hard with the Wife Tax last paycheck.
