If you filed a tax return that requires Form 8962 for the Premium Tax Credit but haven't included it, you will get rejection code F8962-070, which means the IRS needs that form or an attachment explaining the taxpayer’s Affordable Care Act (ACA) situation.
Before 2021, they'd ask for the form separately, but now, they just reject the return if this form is missing.
To resolve the rejection:
the taxpayer has to provide you with the Form 1095-A(s) they received from the Health Insurance Marketplace so that Form 8962 can be completed.
Include a statement on their tax return explaining why Form 8962 isn't needed.
If the taxpayer is not sure about their marketplace insurance coverage or can't find Form 1095-A, they should log in to their account at HealthCare.Gov to obtain a copy of the form.
This reject happens if the IRS knows someone on the tax return had Marketplace insurance or got Advance Premium Tax Credit. It was added in 2021 to fix issues early and prevent delays in refunds. It was the most common reject nationwide in 2021. To fix it, include either Form 8962 or a statement explaining why it's not needed.
If the taxpayer had Marketplace coverage and provided you with Form(s) 1095-A, fill out Form 8962. If they don't need to file Form 8962, they can provide a statement disputing the need for it.
To do this, answer YES to the Marketplace/Exchange insurance question under Personal Information.
Then under Payments, go to Estimates & EIC > Premium Tax Credit >PTC (8962) > ACA Explanation for Not Filing Form 8962.
Choose the appropriate explanation or provide your own.
If you include the ACA explanation, Form 8962 doesn’t have to be part of the return.
