Coronavirus stimulus payments aren’t considered income in bankruptcy, so you don’t have to list them on your means test form or on your Schedule I. If you’ve received your stimulus check, the only place you need to list it on your bankruptcy paperwork is on the Statement of Financial Affairs. Question 5 on this document asks about other recent income you’ve received.
If you haven't received your CARES Act payment authorized in March 2020 yet, it has to be listed as an asset on your Schedule A/B. The stimulus checks approved after March 2020 aren’t considered property of the bankruptcy estate, so they don’t have to be listed.
If you were waiting on your stimulus check when you started filling out the forms and have since received the funds, you can use the case editor to remove it from your Schedule A/B.
