Overview

The Massachusetts Affordable Homes Act, signed into law on August 6, 2024, represents a landmark opportunity for real estate investors and property owners. This legislation creates substantial tax incentives designed to transform underutilized commercial properties into much-needed residential housing while delivering attractive returns on investment.

Primary Tax Incentives

The Act introduces several powerful tax credits specifically targeting conversion projects. These primary incentives form the foundation of the financial benefits available:

• New Qualified Conversion Project Credit
  • 25% of qualified rehabilitation expenditures
  • $5 million maximum per project
  • Transferable credit (can be sold if you lack tax liability)
  • Officially detailed in Massachusetts Department of Revenue Technical Information Release (TIR 24-16)

• Historic Rehabilitation Credits
  • Federal Historic Tax Credit: 20% of qualified rehabilitation expenses
  • Massachusetts Historic Tax Credit: Additional 20% for eligible buildings
  • Can be combined with the Conversion Project Credit for historic properties
  • Potential to cover up to 65% of rehabilitation costs for qualifying properties

• Property Tax Incentives
  • Urban Center Housing Tax Increment Exemption: Up to 20 years of property tax relief on increased value
  • Local Option Special Assessment: Phased-in assessment increases over 5-15 years
  • Requires municipal approval and participation

Additional Tax Benefits

Beyond the primary incentives, several supplementary tax strategies can further enhance project returns when properly implemented:

• Accelerated Depreciation Opportunities
  • Cost segregation studies can identify 25-35% of conversion costs eligible for accelerated treatment
  • Bonus depreciation: 80% first-year bonus depreciation available for qualified improvement property

• Opportunity Zone Benefits (for designated areas)
  • Capital gains tax deferral until December 31, 2026
  • 10% basis step-up for investments held 5+ years
  • No tax on appreciation for investments held 10+ years

The Commercial Conversion Initiative

The Healey-Driscoll Administration’s Commercial Conversion Initiative supports these tax incentives by providing:

• Planning resources and technical assistance to municipalities
• Help identifying suitable properties for conversion
• Assistance navigating regulatory barriers
• Guidance on combining various funding sources and incentives
• Streamlined approval processes for qualified projects

Financial Impact

The combination of these incentives can dramatically transform the economics of conversion projects, turning marginally viable properties into attractive investments.  Strategic layering of these incentives can transform project economics:

• • Potential to increase returns from low single digits to 10-15% IRR
  • Can improve equity multiples from 1.3x to 2.4x
  • May contribute 25-65% of total project costs through tax benefits
