Congress’ decision to suspend the Affordable Care Act’s tax on health insurers for one year will cost the government $13.9 billion, funding that normally would go to cover subsidies for low-income enrollees and other functions of the law.

The CMS, therefore, expects insurance companies to keep their premiums in check when they file 2017 rates this spring. The hope is the one-year tax reprieve will put a ceiling on premium increases and push savings to consumers instead of into the coffers of health insurers.

“Because the fee is not being collected for the 2017 fee year, administrative costs for plans in all impacted markets are expected to be adjusted appropriately to account for the moratorium,” the CMS said in a document posted Monday.
