Colorado’s great migration wave may have reached its peak. The IRS released that Colorado tax returns filed last year by households who had filed under an address in another state or abroad in 2014 was down 21,062 compared to tax returns filed two years prior.

The tax returns also show that California, Texas, Florida, Arizona, Illinois, New York and New Mexico continue to provide the highest number of transplants.

Back in 2014, 10.3% of tax returns in Colorado came from migrating households as defined by the IRS, the highest ratio of any state in the country. Last year, a smaller 7.9 percent of returns were made by migrating households.
