This is how VITA sites handle this.
Entering multiple Forms 1095-A on one Form 8962
Only one Form 8962 may be submitted with the tax return. Make sure everyone on each Form 1095-A is also
on the tax return. If not, this may require the taxpayer to allocate policy amounts with another taxpayer, which
makes this return Out of Scope.
Column A: Add the premiums together.
Column B: If everyone is enrolled in the same
state, the SLCSP premium should be the same
on all Forms 1095-A for a given month. Enter
that amount. If the enrollees are enrolled in
different states, add the SLCSP premiums.
When in doubt, look it up in the Tax Tool for your
Marketplace. See the Tax Tool section later in
this tab.
Column C: (entered in Column F of Form 8962): Add the amounts together.
