Under 28 U.S.C. § 1930(f)(1) the court can waive the Chapter 7 filing fee for a debtor whose household income is less than 150% of the official poverty line and who cannot pay the fee in installments. You can read through the wizard now; it produces the document once its rules are reviewed by a licensed attorney.
The Filing-fee waiver (Form 103B) template is waiting for a licensed attorney to review its rule data. Until then SynthCounsel does not produce this document, so answering the questions will not give you one.
You can still read through the questions to see what it asks and what to gather.
Form 103B waives the Chapter 7 filing fee entirely and is available when household income is less than 150% of the official poverty line and the fee cannot be paid in installments. Form 103A (installments) splits the fee into up to 4 payments and is not income-capped. Both are discretionary with the court. Which one to file is your decision.
The most persuasive Form 103B applications are specific: exact months unemployed, exact medical bills owed, exact rent due this Friday. Generic “I am poor and need a waiver” statements get denied. Treat the statement of need like a sworn declaration to a stranger.
