Immediately after the plan is filed. That is a snapshot of your debt and income on the date of filing. The next day you can win the lottery or get a high paying job and nothing will change.
A chapter 13 is different but you asked about a 7
Be careful. You generally have to bring your current\most recent paystub to the 341 and you will likely be asked if anything has changed since filing. Ideally, you want to wait until after discharge but after the 341 is where many people make changes.
Thanks for the advice, I am going to wait until I get my 341 date then go from there. I should be fine finding a job after the 341 though if I don't have issues?
Personally I would wait 30 after your 341 meeting, because you have to bring your last 2 pay stubs to the hearing. During the 30 days after the meeting, the trustee's office could run a Lexis/Nexis report on you. You don't want to risk your bankruptcy being dismissed. That''s just my persnal opinion and I know that's different than most.
