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".

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.
