Investing your tax refund in projects that qualify for tax credits is a smart way to secure another substantial refund next year. Upgrading your HVAC system, adding insulation, or installing renewable energy sources like solar or geothermal can earn you thousands in credits while cutting long-term costs.
However, only energy-efficient improvements qualify. To maximize your tax savings, it’s crucial to understand which upgrades meet eligibility requirements. Johan Garcia, CPA and founder of After Tax Cash, a site specializing in tax credit guidance for home improvements, offers expert advice to help you make informed decisions.
