Creates an income driven repayment plan for private student loans held by New York state banking institutions

S 4243 creates an income-driven repayment plan for New York residents with private student loans held by New York state banking institutions. It caps monthly payments at 15% of income above the federal poverty level for the borrower's family size, requiring annual income and family size verification. Borrowers who qualify for "partial financial hardship" can enroll, with payments adjusted yearly based on income changes. After 10 years of on-time payments (120 total), remaining loan balances may be forgiven, though forgiven amounts could be subject to New York state income tax. This directly affects New York residents with eligible private student loans from NY banks facing financial strain.
