I have seen where the Marketplace has incorrectly given too much Advance credit. But I'm surprised if they are still doing that.
Check line 3 of Form 8962. Is that about the income that you told the Marketplace?
Is your family size the same as what you told the Marketplace?
Yes, $37,000 for a Household Size of one person would result in about 10% being used for Marketplace health insurance premiums (based on the Second Lowest Cost Silver Plan).
