Americans can now sign up for health insurance plans under the Affordable Care Act (ACA) until 15 August. The window to sign up for insurance through the program normally closes on 15 February, but the Department of Health and Human Services has initially moved the deadline to May, before extending it to the summer.

The extension will give Americans who lost health coverage during the pandemic more time to sign up, and allow more Americans to take advantage of new federal subsidies to reduce insurance premiums granted via the coronavirus relief package.
