Calculate Your Capital Gains Tax Savings With a QOZ Investment:
Instantly compare your after-tax returns with and without Qualified Opportunity Zone benefits.
How does it work?
This calculator estimates the potential impact of reinvesting capital gains into a Qualified Opportunity Zone (QOZ) investment. By combining your input amount with projected deal performance and current capital gains tax rules, it models outcomes over a 10-year horizon. The result is a clear comparison of after-tax returns with and without QOZ benefits, highlighting potential tax deferral and long-term tax elimination on future gains.
1. Enter Your Investment Amount
Just tell us how much capital gain you’re considering reinvesting. This is usually from a recent sale of stock, real estate, crypto, or a business. Our calculator does the rest.
2. We Run the Numbers Automatically
Behind the scenes, we apply the actual projected returns from the First Harbor Square QOZ investment, using a 3.62x equity multiple and current capital gains federal tax rates.
3. Instantly See Your Tax Savings
You’ll get a side-by-side comparison showing your projected 10-year returns with and without QOZ tax benefits — including how much you could save by deferring taxes and eliminating capital gains on future growth.
