The 6-month lookback period is one of the most important -- and most strategic -- aspects of the means test.
The Exact Calculation Window
The lookback period covers the 6 complete calendar months before the month you file. It does not include the month of filing itself. Examples:
- File in January 2026 -- lookback: July through December 2025
- File in March 2026 -- lookback: September 2025 through February 2026
- File on April 30, 2026 -- lookback: October 2025 through March 2026
Why Timing Matters
Because the means test uses this specific window, the timing of your filing can significantly affect whether you pass. Common situations where timing is strategic:
- Recent job loss: If you lost your job 2 months ago, waiting 4 more months means only post-termination months are in the lookback
- Year-end bonus: If you received a large bonus in December, filing in July or later excludes it from the calculation
- Seasonal work: If you earn most of your income in summer months, filing in January means the window includes mostly lower-income months
- Overtime reduction: If overtime was cut recently, waiting helps
What About Income Changes After Filing?
The means test is a snapshot of your pre-filing income. If your income changes after filing, it generally does not affect a Chapter 7 case. However, the U.S. Trustee can file a motion to dismiss based on the "totality of circumstances" if your post-filing situation suggests the filing was not made in good faith.
Strategic timing of your filing is legitimate and common. It is one of the most valuable aspects of working with an experienced bankruptcy attorney -- or doing thorough research as a pro se filer.
