Married people get some monetary bonuses
According to two Atlantic writers who crunched some numbers, married women can pay as much as $1 million less than their single counterparts over a lifetime.
The writers looked at the tax penalties and bonuses, as well as living costs like health spending and housing costs.
According to the Tax Policy Center, a married couple suffers a "marriage penalty" if they pay more income tax as a married couple than they would have as two single individuals. A couple receives a "marriage bonus" if they pay less income tax as a married couple than they would have as two single individuals.
When couples combine their incomes, especially when they have similar incomes, this can push them into a higher tax bracket, which would result in a higher tax rate.
In addition to the tax break you receive from filing jointly, couples are more likely to receive a marriage bonus when spouses earn different amounts.
There are a lot of factors affecting marriage penalties and bonuses, but generally, according to the US Department of the Treasury Office of Tax Analysis, more married couples under the age of 65 filing joint tax returns on average see bonuses than penalties.
According to the BLS data the Atlantic writers looked at, couples also spent on average 6.9% of their annual income on their health, while single men spent only 3.9% and single women spent 7.9%.
And when it came to housing, couples spent on average 23.9% of their annual income, compared to single men who spent 30.3% and single women who spend 39.8%.
By combining resources and splitting costs, married people have the edge on all kinds of day-to-day expenses in addition to rent or mortgage: One cable bill, one utilities bill, and shared groceries can all lead to big savings.
