No. (This confuses attorneys too, so don’t feel bad).
You must wait 8 years between chapter 7s. This 8 year time period is calculated from the day you filed your old chapter 7 case (that eventually received a discharge) to the filing date of your new case.
What happens is that if they don’t qualify for a chapter 7 right away, many people will file a low paying chapter 13 and wait until their 8 years have run between chapter 7s. The chapter 13 protects them from creditors as they wait for to qualify for a new chapter 7.
The problem arises where they want to convert that chapter 13 case after the 8 years have run. The court goes from the filing date of the new case. So if you file your chapter 13 at the 6 year mark and then eventually convert to a 7 after the 8 years have run, since it’s the same case number, the court looks at the file date of 6 years, and your case is dismissed.
If this happens to you, you can file the low paying chapter 13. When your 8 years have run from the file date of the old case, stop paying on your chapter 13 and it will get dismissed for non-payment. You can then file a new chapter 7, since it’s after the 8 year period now, add any new creditors, and receive a discharge.
