Mortgage Credit Certificates (MCCs) are special tax credits designed to help low- to moderate-income homebuyers afford their mortgage payments. By providing a dollar-for-dollar reduction in federal income tax liability, MCCs can significantly lower the overall cost of homeownership. To qualify for an MCC, buyers must meet certain income limits and purchase a home within designated areas. The program is typically administered by state or local housing agencies, making it an accessible option for those looking to buy their first home.
