Jumbo refinance interest remains tax-deductible up to the first $750,000 of mortgage debt ($375,000 if married filing separately).

However, with Madison's 1.85% property tax rate ($424/month on median homes), combined property tax and mortgage interest deductions can still significantly reduce taxable income. Cash-out refinance proceeds are generally not taxable as income. If using cash-out funds for home improvements, that interest may also be deductible. Consult a tax professional to optimize your Madison jumbo refinance strategy, especially given the $275,000 median home values and high loan amounts involved.
