If I owed a total of $1629 Fed taxes, and paid $400 when first filing, then later paid $685 more, what do I do if I get 2 IRS notices saying I owe: $943.14 and $306?

[m0ruth6ne0]

1. I retrieved my "Account Statements" from the IRS website, and it clearly shows both my payments of $400 and $685, which confirms that the IRS received my payments.  This means that my balance should be ($1629-400-685 = $547, and not $943.14).

2. The $306 notice was for "unpaid shared responsibility for 2018", however, I included that in my taxes, in my tax return, therefore, I have already paid for it.

I have tried to contact the IRS, but am unable to do so.

I would appreciate any advice on how to approach this problem?

1) Final amounts for interest/late penalties due can't be assigned until original amount due is fully paid. Thus, two billings is normal under described situation.

2) "Shared Responsibility" implies a second party debt. Filing a joint return? Member of a partnership?

943 -306 = 637
which is close to your $547 plus a penalty and interest

You probably owe the IRS $943.

you didn't state what tax year this is.

IRS penalties can add up really fast.

The shared responsibility payment is billed separately from the federal taxes and cannot have  a penalty or interest added to it ... read the notices carefully.
