If an individual purchased health coverage on the federal marketplace on March 14th, when will the coverage officially begin?

When an individual purchases health coverage through the federal marketplace, the effective start date of that coverage is typically the first day of the following month, provided that payment is made for the first month's premium. In this scenario, since the purchase occurred on March 14th, and assuming payment is made, the coverage will officially begin on April 1st.

This timing aligns with the standard enrollment process and the rules under the Affordable Care Act, which stipulate that the coverage starts on the first day of the month after the enrollment is completed and payment has been received. Therefore, if the $first month's premium is paid, the coverage will commence on April 1st.
