The Tax Policy Center has updated its Marriage Bonus and Penalty Calculator for 2018, including the new GOP-passed tax law. The tool lets users calculate the difference in income taxes a couple would owe if filing as married or separately. “Most couples will pay lower income taxes after they are married than they would as two separate taxpayers (a marriage bonus), but some will pay a marriage penalty," TPC’s Daniel Berger writes. “Typically, couples with similar incomes will be hit with a penalty while those where one spouse earns significantly more than the other will almost always get a bonus for walking down the aisle.”

Housing and Urban Development Secretary Ben Carson will propose increasing the rent obligation for low-income households receiving federal housing subsidies, as well as creating new work requirements for subsidy recipients. Some details via The Washington Post: “Currently, tenants generally pay 30 percent of their adjusted income toward rent or a public housing agency minimum rent not to exceed $50. The administration’s legislative proposal sets the family monthly rent contribution at 35 percent of gross income or 35 percent of their earnings by working 15 hours a week at the federal minimum wage -- or approximately $150 a month, three times higher than the current minimum.” (The Washington Post) 

Anti-tax activists in Washington are renewing their pressure on lawmakers to pass new legislation indexing capital gains taxes to inflation. The Hill provided an example of such indexing that Grover Norquist recently sent to Treasury Secretary Steven Mnuchin: “Under current policy, someone who made an investment of $1,000 in 2000 and sold it for $2,000 in 2017 would pay capital gains taxes on the $1,000 difference. But if capital gains were indexed, the investor would only pay taxes on $579, since $1,000 in 2000 would be equivalent to $1,421 in 2017 after adjusting for inflation.” Proponents of indexing say it’s just a matter of fairness, but critics claim that it would be just another regressive tax cut for the wealthy. Indexing would cost an estimated $10 billion a year in lost revenues. (The Hill)

Sen. Bernie Sanders (I-VT) is preparing to announce a plan for the federal government to guarantee a job paying $15 an hour and providing health-care benefits to every American “who wants one or needs one.” The jobs would be on government projects in areas such as infrastructure, care giving, the environment and education. The proposal is still being crafted, and Sanders’ representative said his office had not yet come up with a cost estimate or funding plan. Sen. Kirsten Gillibrand (D-NY) last week tweeted support for a federal jobs guarantee, but Republicans have long opposed such proposals, saying they would cost too much. (Washington Post)

Childhood poverty cost $1.03 trillion in 2015, including the loss of economic productivity, increased spending on health care and increased crime rates, according to a recent study in the journal Social Work Research. That annual cost represents about 5.4 percent of U.S. GDP. “It is estimated that for every dollar spent on reducing childhood poverty, the country would save at least $7 with respect to the economic costs of poverty,” says Mark R. Rank, a co-author of the study and professor of social welfare at Washington University in St. Louis. (Futurity)
