Provides refundable gross income tax credit for early principal payments on certain home mortgages.

This New Jersey bill (S 1763) creates a refundable tax credit for homeowners who make extra principal payments on qualifying mortgages. Taxpayers can claim 50% of these extra payments, up to $1,000 annually, reducing their state income tax bill (or creating a refund if the credit exceeds tax owed). To qualify, the mortgage must be for a primary residence, be a traditional 15-30 year loan, and the homeowner must meet income limits (e.g., single filers with $125,000-$135,000 taxable income see reduced credits). The credit applies only to payments beyond the required monthly amount and cannot be claimed for more than 10 years total.
