In February, the U.S. State Department published budget requests for the next fiscal year. They estimate that in the current FY 2016 (which ends in September), they will spend US$27.4 million on reimbursing international organisations for those organisations’ reimbursements to their U.S. citizen employees for the U.S. taxes paid by those employees — $9.8 million (56%) more than they did ten years ago.
This is a fast-growing budget item in an area where Congresscritters have been trying to cut back after period of high spending growth in the late 2000s: State officials estimate that their total spending on “Contributions to International Organizations” (CIO) will be only about 12% higher in 2016 than in 2007, and have only requested 7.5% more than 2007 in the 2017 budget.
