Part III column B is the Second Lowest Cost Silver Plan (SLCSP) applicable for your household. This must be filled out for every month someone in your household is covered by the Marketplace. The SLCSP is used in the calculation of your premium tax credit.
The SLCSP premium is incorrect if:
- Part III, Column B has a “0” or is blank for any month someone in your household had the Marketplace plan
- You had changes in your household that you didn’t tell the Marketplace about — like having a baby, moving, getting married or divorced, or losing a dependent
If either applies to you, you’ll use the government's tax tool to get the premium for your second lowest cost Silver plan and fill that cost in column B of form 1095-A. Failure to do this will result in a wrong calculation of the premium tax credit.
